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.

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. ❤

That is what my ranking too 1.transprk 2.relex smile 3.lasik Thank you doctor for the information and clarity

I did PRK last week and KZfaq suggested this video now🙂

Thank you for this video.

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?

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.

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 🕶️🕶️

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.

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!

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!

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.

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.

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?

Thank you 😍

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?

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.

Do you have a maximum negative diopter you treat with tprk? Edit: given a corneal thickness you would deem thick enough.

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?

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!

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 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 :)

Great video. I subed.

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?

Thanks 😊

Hello doctor. How common is corneal neuralgia after lasic or prk ?

Doctor which is better relex smile or schwind amaris 500 touchless for myopia-2.5

Hi, is implantable contact lens even better than trans prk in terms of biochemical stability? thank you so much for this informative video!

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?

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? :))

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.

Hey doc my doc also suggest me for trans prk I have myopia -2.5 so should I go for that?

Thank you

I am software engineer can I go back to work on laptop after 10 days of trans-prk?

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

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?

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?

Hi doc, my diopter is -7.0 ,cyl -2.75 axis 15 on left and -6.0,cyl -2.75 axis 170 on right eyes. I also realize that my pupil is larger a bit. What is the best procedure should i go. At my place they only have lasik,smile, and prk..

Which is better epi-contoura or epi- hdv2.0

درود آقای دکتر بسیار مفید بود🇮🇷🇮🇷👌🏻👌🏻

Any idea why transPRK hasn't been approved by the FDA?

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!

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. Regards.

Is touchless lasik same as prk My no is -3. 75 sp -2. 00 cy 5 axis right eye In lef eye -3. 25 sp and -1. 50 cy axis 175 and my corneal thickness is 571 both eyes ... What could be the procedure to remove my glasses

I have -9 and -7 and thickness of 540 mm which one is better for me prk or contoura vision please suggest me

Have you heard about a method called the Bionic Eye, by Dr Garth Webb. From Vancouver Canada?

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 did prk 3 yrs back basis studying the pros and cons... absolutely loving it since 3 yrs...

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.

Hello doctor. I had prk surgery the older version in 2015 my cornea thickness was 530mm. I was 22 yrs when I did prk. I had cyl -3 both eyes. Got pregnant at 25 yrs n my vision started becoming blurr, now at 28 I have 0.75 cyl power, -1.75 sph power I'm wearing spectacles again, now my corneal thickness is 457 mm . Feel like the surgery went for a toss. Kindly suggest what should I do?

Dear Sir, thank you for this very informative video. I have a couple of questions. What are the advantages of trans prk compared to relex smile if we exclude the price aspect? In what cases a patient with high myopia and astigmatism, who is a good candidate for both relex smile and trans prk, should choose trans prk and not relex smile?

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?

Good to know after i chose PRK :D

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

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 1. people says that laser destroy your cells rather than with blade so the chance of ingrow risk are high is it true? 2. what do you think about smartsurface transPRK ops do you recommend it? i am a nearsighted -3 both with little astigmatism

Hello Dr Hafezi I am considering TransPRK, I am -8.5 in both eyes and age 43, as of yet I am not experiencing Presbyopia so should I avoid any monovision treatment and is it better to leave my soft contact lenses out 2 months prior to consultation or two weeks , would it make any difference to the final outcome of surgery.Regards Dr Hafezi

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??

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 :)

What about evo visian icl?

Hi Doctor what about Smart Surface vision correction

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

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.

Hello, can you list possible pricing of the procedure as the same procedure is not available in India right now .... they are just selling Contoura Vision at top pricing which is specialised version of LASIK

i did relexsmile in 2020 and transprk few days ago, because my eyes were so bad i had to do it in 2 times

Where can i go to have trans prk done

Hello doctor could you please take a min to answer my query I had my prk done a month ago I am having 6 by 6 but i m seeing floaters and flashes my surgeon examined my retina and said that there is no tear or Detachement is it because of my prk I m seeing floaters and how long would I have to deal with them thank you

Hi! So would you recommend transPRK even over femtoLasik for 7 diopters of myopia? Does the risk of cornea opacity exist in transPRK?

Sir ...I had prk in 2019 pre prk I had simple myopia and my corneal thickness is 499 microns in right and 489 in left ..after surgery I achieved 20/20 vision but I saw floaters little bit ...I have an experience with that floaters since my childhood but post prk one year later it was very noticeable and dryness is also increased when I woke up....upto one year my vision is perfect and no dry eyes and issues but after completion of one year I facing the so many minor complications my night vision is also very disturbing seeing stars and glare .....why all this was happening to me....please help Dr.

where is transPRK available? is the price similar to PRK?

What about corneal haze isint prk have that disadvantage over lasik

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.

So PRK is better ?

Hi sir i got prk on October 7 my eyes are not clarity when did I get clarity sir pls tell me

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)

My doctor choos PRK but I choose femto lasik.. Best decision of my life No dry eyes no halos Perfect eyes🥰 From pakistan

Is corneal neuralgia a possible side effect of TransPRK ?

Is streamlight and trans prk are same?

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.

What type of lasik did you had to yourself??

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.

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

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.

What’s the probability of having permanent dry eyes

Is Trans PRK just LASEK?

I made an uniformed decision and decided to go with LASIK. I regret my decision.

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.

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!
