- When it comes to comparing transPRK to LASIK today, things have certainly changed. Modern bladeless and touch-free transPRK is not comparable to the original PRK method from the 1990s. Also, a transPRK is safer than LASIK surgery.

I just got PRK 5 days ago and I gotta be honest the recovery on the 2 and 3rd day SUCKS my eyes were burning so bad, but then on the 5th day it was like a switch and everything stopped burning and my vision started to instantly improve, such a crazy process
Thank you so much. You made my decision making process easier.
I did PRK last week and TH-cam suggested this video now🙂
You lucky, lucky boy!!!
How are you now?
@@da_great_mogul I'm good and I can see the things that I can't see before 😀
@@DavidKristen so happy for you, you made the right moves.
@@da_great_mogul thanks and God bless you
Thank you so much for this explainer! Having the development of the field and techniques laid out like this helps make sense of the options available now. I learned my cornea isn’t thick enough for Lasik and have access to transPRK (with Streamlight).
I still wonder about hazing during the recovery process and beyond. I was told the first months are critical to shield the eyes from UV light, but also that one needs to be careful for 1-2 years afterwards, and that always wearing sunglasses on sunny days should be best practice for the rest of one’s life.
Am I simply overreacting and overthinking how careful one must be, and / or how sensitive are the eyes to hazing after the first months of the surgery? Apologies if you already have a video answering this question, thank you already for this one.
woooooow. what an amazing explination. you just conviced me doctor to get trans PRK surgery. I wish u were close to me you would be my top doctor to go to. You ara an amazing person. ❤
As a martial artist and footballer, I had to undergoe transprk 6 days ago in order to continue playing the sports I love.
Indeed it's much safer than all Lasik-Smile surgeries but it takes longer to recover and was very painful during the first 48 hours after surgery, other than that, I have had good vision and I even ordered a fancy monochromatic sunglasses 🕶️🕶️
Great to hear: we have developed a new postoperative pain regimen that substantially reduces postop pain. We have been using it without issues since 2015, see here: pubmed.ncbi.nlm.nih.gov/35887874/

Hi! My doctor was also suggesting trans PRK for me. I'm very nervous for the procedure because of the healing time but thank you for your informative video I have less doubts now.
How did the procedure go? I''m so anxious because my surgery is in 2 weeks now
@@lililiz7869 the procedure was very quick. As for me since I have high grade, my right eye took about less than a minute whereas my left eye took 1minute more or less. After 5 months now, no regrets for the procedure. It's okay to feel nervous but always remember it is always a step towards a clearer sight for a long time. Bye glasses or contacts soon for you.
@meleesaclarin7367 Hiii hoep you're okay, how are your eyes now? Also what was your initial prescription and do you have any regrets?
Sir I'm glad that you uploaded such kind of helpful video for us. As my surgeon suggested me to go for PRK Over LASIK as my both eye numbers r -5.25 and cornea thickness is 515-520...but at somewhere i still confused to go for it or not,for future it will be okay for me?
There is any risk for vision or anything,m afraid.
Could you give me your opinion sir?
Doctor, first I want to congratulate you on your excellent work.
Is there currently a therapeutic surgery for Post Lasik ectasia? I developed corneal ectasia only in my left eye 5 years ago. I had Crosslinking in 2016 and it has been stable since then.
Great to hear. In fact, we developed cross-linking for ectasia after LASIK and were the first to treat, see here: pubmed.ncbi.nlm.nih.gov/18053900/
And yes, there are options on how to improve vision after cross-linking in ectasia, see here:
www.elza-institute.com/cross-linking/improve-vision-after-cxl-cross-linking/
I got my FEMTO LASIK done 3 days back but I wish I had watched your video before it as you mention TRANS PRK is more stable long term, and your logic does make sense. I was turned off by it due to my nature of work and the doctor mentioning that PRK takes about 1 month to show full results while LASIK shows results instantly and full recovery in 1-2 weeks.
I would not worry too much. Femto-LASIK also is very safe. When I say that transPRK per se is safer than Femto-LASIK, then we speak of two methods that both are safe, but one is even safer than the other. Because in medicine, it is all about making good therapies even better.
@@ELZA-Institute Thank you for the prompt response. I am a bit relaxed now with what you've said, however, could you also clarify if the effects of Femto LASIK wear off faster than PRK and will my flap dislodge anytime in the future considering I will be getting into combat sports like MMA or Boxing?
@@humantorchid i wonder about the same thing.. 😅
@@humantorchid you make sure that for 3 years you limit all extreme sports, sir.
@@da_great_mogul Noted, I've avoided getting into MMA for now. And even if I do, I'll limit it to everything except face.
Thank you 😍
Thank you, sir! Very helpful and informative. I am still considering ICL vs transPRK, however I am now leaning towards tPRK due to the halos side effects and abrasion risk of ICL.
I'm still considering ICL due to its reversibility as opposed to laser options due to the risk of severe chronic dry eye. My mother and uncle both had LASIK, and still have severe dry eye 10 and 14 years later, so I am very afraid of laser eye surgery.
Hello! Indeed, LASIK may lead to dry eye, because the nerve endings of the corneal nerves are compromised. This may also occur in transPRK, but much less.
@@ELZA-Institute Thank you for the reply sir. I just had standard modern PRK (brush epithilial ablation) on May 3rd. So far my eyes are still stabilizing other than night time dry eye is my only issue.
@@mikeag how you doing with dry eyes now hope youre going better
@@icdlight9284 my eyes are slightly noticeably dryer and more sensitive to light. That's to be expected and recovery is stated to take a full year. It's not bad at all and God blessed me with a miraculous recovery; even yhe Doctors thought my surgery date was incorrect in the file becasue I was so ahead of schedule in recovery.
If you do PRK be absolutely sure to protect your eyes from UV for at least a full year.
Absolutely would do it if I had it to do again. The hardest part was my eyes are 10x more sensitive to touch and I am immune to the effects of tranquilizers so no calming or sedation for the surgery and it was nearly impossible to hold still and not blink.
@@mikeag how are you now Michael? Sorry to ask and I know it isn't so important now you've had your procedure but why did you opt for standard PRK over the Trans PRK (AKA streamlight PRK), as advised by Doctor Farhad in the video?
Dear Doctor
This was very insightful and I only wish I'd saved myself one month of research and seen this sooner!
I agree that the advantages of trans PRK (as known as streamlight PRK that I'm booked in for this week) outweighs any negatives.
However, I believe that trans PRK destroys Bowman's layer in a way LASIK does not. Whilst I appreciate that there is no medical evidence that supports the role of this layer, is this something to be overly concerned with?
Is there anything I can do to ensure the surgeon enlisted for the procedure has the required skill and success rates?
Thanks again and I hope to hear back from you before my streamlight PRK procedure on Thursday!
Hello Doctor - I am a candidate for both SBK and PRK, however leaning more towards the latter treatment. If you can provide some insight for the following:
1) Is there a risk of significant vision loss as a direct result from the PRK laser treatment?
2) Would you recommend undergoing the PRK surgery one eye at a time?
Thank you!
Thanks 😊
Thank you for your video, it is very informative and helpful in understanding the procedures. What is the difference between trans prk and Lasek procedure?
LASEK has been more or less abandoned in the past years because the epithelium is not really viable after the alcohol treatment.
@@ELZA-Institute when you say no longer viable, is it just that it takes longer to recover? I am in the US so it seems like the best option (ASA or Lasek), if I can’t get transprk.
Hi
Thank you
Good to know after i chose PRK :D
درود آقای دکتر بسیار مفید بود🇮🇷🇮🇷👌🏻👌🏻
Dear Doctor, I have done Lasik in my early 20s and now in my early 50s. I couldn't do the Femto-Lasik due to my thin cornea.
Due to aging, my Myopic power has increased since my last Lasik and now with Hyperopia, and possibly of Cataract in the near future, would you suggest it would be good to go for TransPRK ?
Can TransPRK solve the thin cornea issue to correct both my Myopia and Hyperopia?
Great video. I subed.
Thanks for the sub!
Hello Dr.Hafezl i would like to ask you something and i would really appreciate it if you could help me.i have 1.5 myopia and 0.25 astigmatism,do you think its worth it to have an eye surgery for this amount of myopia?
i would really appreciate your help!
looking forward for you reply!
Thank you!
Do you have a maximum negative diopter you treat with tprk? Edit: given a corneal thickness you would deem thick enough.
Hello doctor. How common is corneal neuralgia after lasic or prk ?
Hi, is implantable contact lens even better than trans prk in terms of biochemical stability? thank you so much for this informative video!
Hi, yes, absolutely. But ICLs come with other risks including increased intraocular pressure or early cataract formation. Please consult with your treating surgeon.
Hi Doctor. I'm convinced that trans PRK is the best option and I'm undergoing the surgery (smartsurface trans prk) in Singapore in two weeks. Due to the high correction required, (-500 + 200 astigmatism), my doctor recommended corneal cross linking. Is there anything I should take note with regards to recovery? For example, I've read that consuming flaxseeds and more omega 6 can help with recovery though it might be a placebo effect. Thanks for reading :)

Have you heard about a method called the Bionic Eye, by Dr Garth Webb. From Vancouver Canada?
Hello doctor could you please share the things that should not be done after C10 procedure and to be avoided. Also after 3 days does the vision go back to normal? I have heard cases where peoples vision still stays blurry. Also will there be migraines or sharp headaches after it? Also would really appreciate if you guide me whether C10 is the right procedure or not as that is the only one available in Kenya.
I am software engineer can I go back to work on laptop after 10 days of trans-prk?
My eye prescription
right eye: spherical: -5.50, cylindrical: -0.50, axis: 15°, acuity: 6/6P
Left eye: spherical: -5.75, cylindrical: -2.00 axis: 5° , acuity: 6/6P
Had my pre LASIK test. The surgeon said that the cornea is thin, about 508 um so 6/6 couldn't be possible with LASIK, I may need to wear -1 glasses after LASIK. He suggested me ICL which is very very expensive here.
My question is, Can PRK correct my vision around 6/6 with this thin cornea? Am I a good candidate for PRK? Can PRK correct my astigmatism?
Hello Doctor, thank you for this informative video.
I have a 2 part question. I am 2 weeks away from getting laser surgery. I was not quite sure if I would prefer LASIK or PRK ...but after this video I think I will go with PRK. My question is, being that I apparently have thick cornea tissue (in the 500s), is PRK still a better option? And if so, is transPRK an even better option than PRK? I am not quite sure of which my doctor uses.
Thank you.
Hi. Please note that PRK and transPRK are quite different. A PRK procedure can also be performed on a 15 year-old-technology with older ablation algorithms and poorer outcome. Similar in LASIK: a modern Femto-LASIK shares the name with LASIK with a blade system, but is quite a different procedure.
@@ELZA-Institute Dr. Farhad, this patient asks some good questions. In cases where a healthy thickness of cornea is identified and the procedure will not render a post operative coronal thickness of less than 300 microns, is your logic of Trans PRK instead of LASIK still valid?
Also, is Trans PRK greatly more advisable than PRK (I think you did answer this in your reply in fairness)?
Hi Doctor, I got my trans PRK done 5 days back ( goes by the name T.E.S.T at the clinic), but they used a SOLID STATE CUSTOMVIS PULZAR Z1 machine and not SCHWIND. They said it had more advantages in terms of temperature and no excimer. Is it true ? Or Schwind is the best machine in current times? Which one do you recommend?
I did PRK about 6 weeks ago, so I am interested because I can not find information anywhere, when can I go back to lifting weights at gym and doing strength exercises?
Any idea why transPRK hasn't been approved by the FDA?
Which is better epi-contoura or epi- hdv2.0
Hi Doctor, I'm currently considering Smile and transPRK but still don't know which to choose. My eyesight is -5.00 with 1.25 and 1.50 astigmatism, and the cornea thickness is around 530. I prefer transPRK but I'm also concerned about getting haze, also I've got acnes before and may I know will it increase the possibility of getting haze post operation, please? I'm thinking about Smile as well but I'm also worried it will leave my cornea too thin and would cause keratoconus, especially in the long term. May I ask which one would you recommend, please? :))
Why don't you find a good Dr. and have yourself fit with proper contact lenses..
Doctor which is better relex smile or schwind amaris 500 touchless for myopia-2.5
In case someone has acne that affects the eye making it look red(small veins visible around the cornea) and is advised not to wear contacts as they can lead to an infection, as long as they are totally viable for the upcoming procedure, would trans prk be a good option over the femto lasik procedure? I'm making this question as post trans prk you got to have contacts for a couple of days constantly.
This is a special bandage contact lens and it cannot be compared to the usual contact lens wearing.
i did relexsmile in 2020 and transprk few days ago, because my eyes were so bad i had to do it in 2 times
Thank you so much for the video! I had lasik 14 years ago and it went well. However I feel the results are worn off... I wanted to ask for people who had the Lasik surgery can do Prk for enhancement or can just do Lasik again?
If you can have lasik again depends on the residual thickness of your cornea, people on youtube can't tell you that
Hello professor,
I have -4.5 and -4.75 with cornea thickness of 485mm. My surgeon recommended me Relex over Lasik to ensure cornea stability because of the thinness of my cornea. Unfortunately she does not offer TransPrk. Even though I paid for all the initial exams I now look for a surgeon who offers transPrk after watching your videos.
What is the min thickness of the cornea transPrk is performed?
Thank you so much for this informative video!
Depending on which country you live in, you should have steady access to this technology, with the exception of the USA.
So you can’t get transPRK in America?
Hello dear doctor, I want to ask you 2 questions, I will be very happy if you answer my first question. Is there a difference in success percentage between the transprk and the prk made by scraping? my other question is whether prk or smile will be more successful in moderately myopic eyes
Hi. transPRK is touchless so there is no interference from a blade. In moderately myopic eyes, I would prefer transPRK because whenever there is an additional step (pocket and lenticule creation in SMILE), there is room for additional complications.

Hi Doctor
what about Smart Surface vision correction
Hi. SmartSurface is the most modern version of transPRK and is used on the Schwind Amaris laser system. This is the system that I am using and is the most advanced surface system in my eyes. The system is available globally with the exception of the USA.
Do you feel the streamlight system is a safe and effective alternative to the Schwind Amaris system? Or would you try to find a clinic using the latest Schwind Amaris system? I am only aware of one clinic in my current country (Colombia) that has the system you are using.
I have no experience with that Alcon system and method because it is new to the market.
Michael, the Schwind Amaris is the machine used to correct your vision.
You can pair trans (streamlight) PRK with a customised treatment laser all with the Schwind Amaris machine.
Likewise, the same can be said for the Alcon EX500 machine also. These are machines, not techniques. Think of BMW or Mercedes-Benz driving you to the next city. They're both making the same journey but it's via two differing motor vehicle manufacturers.
Thanks for the information doctor! I had iLASIK 7 years ago, but my right eye got a bit worse in the past few years. Now I have about 0.75 of astigmatism. My doctor recommended TransPRK over lasik, since my flap is probably too healed to lift it up again. Do you think I have a higher chance of side-effects or failure in the TransPRK procedure since I had ilasik in the past?
It is typical to perform a second procedure as transPRK, this is what I do in most cases of older LASIK, too.
How did it go?
@@evafraga1706 It went really well. The recovery from the TransPRK was much slower than with lasik, but I recovered well anyway with 20/20 vision.

That was a wonderful video !!
I was just confused as I didn’t find any procedure named Trans PRK in my country (India) instead I got to know about some other blameless procedure like Contoura Vision and zLasik / iLASIK / Femto LASIK
Can you give a simple difference among these... Please :)
I know that a number of surgeons use transPRK in India, i.e. those who use the Schwind Amaris platform.
Thanks! The laser in question is the AMARIS from Schwind and to my knowledge there are a number of clinics in India using that laser.
Hello doctor. I am planning to get my surgery done in next few days. I wanted to understand if I should choose prk over smile ?
I am eligible for all techniques. I have tried to understand the pros and cons of each technique. Smile being the advanced version and eliminates the risks of other techniques and still retain the advantages. Is it a better option ? Or I should still stick to trans prk (being painful and slow recovery) ??
Waiting to hear from you ASAP cz I am getting it done in next couple of days.

If transPRK is not available, then standard PRK is not really a good option with these values. The rest depends a lot on your individual topographical and refractive data.
What about evo visian icl?
Except safety, in which transprk is superior to lasik, what is your personal experience about efficacy? Does it work as effectively as lasik in terms of correcting myopia and astigmatism?
Yes, absolutely, but in very deep ablations, the time to healing is longer. Up to -8D, the precision is very high, then it is lower without an increased risk profile.
Hi Professor,
My both eyes sight is -3..they had done all the tests and doctor said that I am eligible for PRK/LASIK/FEMTOLASIK.
which one would be a good option?
thanks.
I would always prefer a surface treatment via transPRK, if the examination is in fav our of it.
I have -9 and -7 and thickness of 540 mm which one is better for me prk or contoura vision please suggest me
If your cornea allows for it regarding topography, I would do a transPRK, because your corneal biomechanics will be much better.

Hello sir, i want to ask about trans PRK i learned that it is laser your outter layer through cornea to fix it. my question are

2. what do you think about smartsurface transPRK ops do you recommend it? i am a nearsighted -3 both with little astigmatism

Feel like the surgery went for a toss. Kindly suggest what should I do?
You were far too young to do anything on eyes that were clearly still not stable. Would you cut a newly laid grass lawn? You might be OK for trans PRK given you only need a very small amount of tissue removing from your cornea. However, please wait until you're 32 to 35 for that.
Hello Doctor, My eye sight is still 6/9 and little hazy after 2 weeks of trans PRK. Is it normal? Also near vision is slightly blurred when using mobile phone
Hi. Yes, petfectly normal after 2 weeks. Make sure to see your surgeon in the next 2 weeks.
Dear sir,
My eye error is -7, and corneal thickness is less than 500 microns. Doctors said With this features LASIk is not suitable. Is there any eye surgery for thinner corneal??
In such a case, and if all other factors are in favour of it (symmetric topography of anterior and posterior corneal surface, age, etc), then a transPRK makes much more sense than LASIK because one spares a lot of precious tissue with it.
Hello Doctor. Would you still recommend Trans PRK over SBK? I qualify for both, but I am getting really scared of the bad stories that I am hearing from those who have done Trans PRK and their eyesight still isnt 100% recovered for months. Thank you
Hi. SBK is a good option whenever a transepithelial excimer laser is not available. A modern transPRK laser makes the SBK obsolete.

Sorry, I focus on the medical and scientific aspects, cannot give any advice here.
You can have Contoura with trans PRK too. Contoura is simply put, the second treatment laser.
Hi! So would you recommend transPRK even over femtoLasik for 7 diopters of myopia? Does the risk of cornea opacity exist in transPRK?
Hi. If the specifics of your cornea allow for it, I would choose transPRK over LASIK. We can control haze up to 12 D of myopia.
I don’t understand … i thought Relex smile is the state of d art now ? (And the most expensive now due to very fast recovery)
SMILE was the last method that came to market. transPRK is the newest version of the method that started the whole field.
Could women's eyes be affected if they have pregnancy within 5 years after surgery (either TransPRK or Smile)? Many thanks for making human life better.
Theoretically yes, but the number of ectasias reported after PRK is extremely low. To my knowledge have ever been reported a few years after PRK or SMILE during pregnancy. However, we published on a number of ectasia-after-LASIK cases in pregnant women, that started even 9 years after LASIK. pubmed.ncbi.nlm.nih.gov/22496434/
where is transPRK available? is the price similar to PRK?
transPRK has been in clinical use in Europe and most parts of the world since 2005. For now, to my knowledge,it is not available in the US yet.
So PRK is better ?

@@priyanshutripathi7738 Hi bro how is your vision
Hi. I'm considering to have PRK in only one eye, to correct astigmatism of -2.50 , with no spherical correction. I realize PRK is less invasive than LASIK and doesn't have the potential risk with the flap that comes with LASIK. My question is, once healed, is the epithelium/eye as strong after PRK as it is naturally before surgery - in terms of possible injury, wind, sun etc? I mean after fully healed, 6 month post-op onward. Also, while I realize PRK is less apt to cause dry eye than LASIK, would someone having PRK only on one eye generally experience more dry eye in that eye than in the eye not operated on? Again, I mean after the eye is fully healed, after 6 month. Thank you.
I had PRK done and both eyes healed in different way. My left eye was very dry while my right eye i didn't experienced any dryness at all. Was 20/15 after 3 weeks with my right eye and 20/30 with my left. After time (3 months) my left pair out with my right eye at 20/15. So I guess if you're having the procedure in only 1 eye it would be hard to compare how fast or slow your eyes are healing. Dryness went away after 8 weeks. My prescription was -6.00 right and -5.50 left. Just make sure you get the procedure done with an eye doctor that doesn't work in a lasik institution those places are shaddy!
What about corneal haze isint prk have that disadvantage over lasik
Hi. It used to until last year when we presented our result of 7 years of research: the extremely smooth surface in transPRK allows us for the treatment of extremely high myopia without significant haze.

Is corneal neuralgia a possible side effect of TransPRK ?
maz hussain i haven‘t seen corneal neuralgia following PRK since I perform them (since 2002)
So ecstasia wont come up with in several years of PRK?
@@ravenmilian63 It can. It always is a question of the dosage, as Paracelsus said. So when a surgeon exaggerates by removing too much tissue, then even a PRK may develop ectasia. But the relative risk for ectasia is far lower in PRK when compared to LASIK or SMILE. And in surgery, it is always about reducing the risk.
@Salty Kraken Bowman's membrane does not contribute to corneal biomechanics. We have done the research and the manuscript has recently been submitted. For all other issues, I strongly suggest to talk to your treating surgeon. You must be comfortable and he/she should answer all open questions. Regarding epithelial removal: this is a standard in Europe since 2008, it is called transPRK.
@Rock Band, Drums, Guitar Reiser Music Studio Reiser will do, thanks!
Is streamlight and trans prk are same?
yes
Excellent question... I wish there were generic terms to cover all procedures as it would stop us needing to know the different terms each manufacturer uses.
Would you saw its safe for someone with custom intralase lasik to participate in water sports like water tubing and water skiing? It seems like the flap is pretty weak after surgery. I am not confident that a lasik flap can withstand a hard impact on the water like what is common with these sports. My surgeon says otherwise.
*say
Hi. Let me answer in a general way. The flap has good adhesion to the underlying wound bed, but biomechanically, it takes very long to contribute to biomechanics. And I had a patient of mine 15 years ago who unfortunately received a leaf of a plant into her eye 3 years after Femto-LASIK. The leaf went into the interface and sheared off the lamella. So mechanical stress can, under certain circumstances, become a real danger to the integrity of the flap. This is why, i.e. in Switzerland, professional pilots cannot have LASIK surgery. PRK (and transPRK) are ok to perform. So if you have a profession or are performing a sport that runs the risk of mechanical impacts, a surface ablation, if applicable, is potentially safer.
Oh okay. So as long as a solid object doesnt get under, or sheer the flap it shouldnt be a problem for the most part. Also, i can only assume that a patient you may have seen 15 years ago probably received bladed lasik, instead of the more modern all laser lasik. Im kindof amazed that it only took a leaf to dislodge her cornea regardless of what procedure she received. Would you say that the technological advancements from bladed lasik to intralase lasik help keep the flap down when it is undergoing abuse from blunt impacts?
@@stupidmilkshake4887 I was looking for the right term: it was a leaf from a yucca, so definitely a very robust leaf. Whenever there is a chance of a blunt impact, I would not opt for LASIK.
That is good information. It seems i made a terrible mistake then as my surgeon assured me of its safety. I am into contact sports and such. He never mentioned PRK to me despite him knowing I am a younger man that has a rougher lifestyle. That is very upsetting to hear how fragile my eyes are now. Thank you for being honest. I wish you were my surgeon
What type of lasik did you had to yourself??
This was back in 2008, so I had LASIK with a mechanical blade for 7 diopters of myopia. Today, I would rather choose transPRK. LASIK is safe, but transPRK is even safer.
@@ELZA-Institute prk or trans prk which is safer
My doctor choos PRK but I choose femto lasik..
Best decision of my life
No dry eyes no halos
Perfect eyes🥰

Great, there is no right or wrong: in quite a few patients, both are viable options.
Hi sir i got prk on October 7 my eyes are not clarity when did I get clarity sir pls tell me
Hello, did u get clear vision??
when the laser work, then our eyes moved, what will happened? I ever had this surgery. about 3 month ago. and now my left eyes still got the double shadow. I've worried that I made a mistake when the laser work. Im sure that my eyes moved down when the green light is off.
Hopefully its not my problem then my eyes still on recovery progress.
Modern-day lasers have eye trackers that are faster than any inadvertent eye movement can be, so if you were operated with a modern laser, this cannot be the reason for a double shadow. This shadow could rather be due to prolonged healing, or something in the ablation profile "increased" your wavefront errors.
If you can afford to take a week or two off work, PRK is a no-brainer. Yes, it takes longer to recover. But it keeps your eye much, much healthier.
But unlike LASIK, you lose Bowman's Layer forever as it'll never regenerate.
@@da_great_mogul That doesn't really mean anything. It's a layer of cells that perform no critical function. Hell, their most important function is to be removed to have PRK done.
@@L11ghtman are you a qualified Doctor?
@@da_great_mogul Nope, but I've read all the research papers and talked to my surgeon before choosing PRK. Bowman's Layer does not regenerate, but the other cell layers do, and they regenerate over where Bowman's membrane was. Effectively they replace it, and so far, nobody has any idea what Bowman's membrane does. Altering your eyes has repercussions either way--LASIK creates a permanent flap and cuts deeper into the tissue, resulting in the risk of less eye tensile strength. Both procedures are overwhelmingly safe and effective though.
@@L11ghtman I'm not sure about the permanent flap created by lasik to be honest. It's a tissue so the slit will surely heal.
I made an uniformed decision and decided to go with LASIK. I regret my decision.
Hello sir. I have a corneal thickness of 512mm and -8 on both eyes. My doctor recommended me not to go for LASIK as well as PRK, instead he suggested me to go for ICL. However, i thought minimum thickness required is 500mm. Could you please share some insight? Also could you share your email id if possible: I'll share you my Pentacam reports. Thank you
It's 500 microns, not millimetres! Are you aware that 500 millimetres is half a metre? I'm no surgeon but I can tell you that no one has a corneal thickness of half a metre.
@@da_great_mogul hey yeah my bad, but you got my point right 😂
@@da_great_mogul also I had my PRK done one month ago, everything is going great as of now
@@samkitbarbhaya4698 any pain?
@@josenunez3506 pain was there only for the few initial days, after that my eyes are fine af... No issues as such... Prk is a blessing for me!!
What’s the probability of having permanent dry eyes
There always is a chance of dry eye after refractive laser surgery, but the risk is much smaller in PRK. In contrast to LASIK, the nerve endings are not cut by the flap, which is a driving force for dry eye.
@@ELZA-Institute And compared to the newest Smile (Smile pro 2022) with 1,8mm cut?
I mean SmartSurf tPRK vs SmilePro?
Is Trans PRK just LASEK?
These 2 methods are fundamentally different in their approach to precision of the surgical result and healing.
PRK disrupts corneal structure affecting epithelium, Bowman's membrane (never grows back), and anterior stroma (never grows back). Epithelium healing is a complex process. With corneal regeneration many inflammation and complications can occur through the life but with flap dislodge its extremely rare less complication. ( if occurred also its again its very very rare).
If you touch or poke with finger or sky dive still flap wont move after 6 months. And by the time you damage flap your eyes structure will be deeply damaged by all means. Whether u had lasik flap or not, in accidents your eyes will be damaged. In healing process if small accident occurred also flap portion can be easily placed on eye with eye drops
The other problem associated with the PRK, is the increase in a corneal haze with the treatment of higher refractive errors. It is because the epithelium cells can never be removed completely, by either alcohol or laser and these tend to grow more haphazardly.
There is also an increased risk of infectious keratitis or corneal ulcer with surface ablation compared to LASIK due to the longer epithelial healing period since the protective epithelium has been removed.
Remember, everytime you get a corneal ulcer, you are going to get another scar. And the next scar might be in the central cornea, if you are unlucky enough, and that would permanently affect vision. The eye is a pretty fragile thing, and some things, once they happen, may not be reversible. The most important thing is to prevent such things from ever happening again.
You are right, It all is a question of assessing the individual risk.
thank you for this video ,very informative and to the point
i cant even hear you? speak louder
Hello Dr.Hafezl i would like to ask you something and i would really appreciate it if you could help me.i have 1.5 myopia and 0.25 astigmatism in both eyes,do you think its worth it to have an eye surgery for this amount of myopia?
i would really appreciate your help!
looking forward for you reply!
Thank you!
