Hello everyone,

I'm looking for some advice regarding eye prescription measurements before vision correction surgery.

I recently had my eyes tested at two different clinics while exploring surgical options, and I received significantly different prescriptions.

The first optometrist started from zero power and gradually increased the lens strength until I could clearly read all the letters. The final prescription was actually lower than the glasses prescription I'm currently wearing.

The second optometrist started with my current prescription and then increased the power further until my vision improved. This resulted in a prescription that was about 1 diopter stronger in one eye.

For example:

First clinic: -7.00 and -7.50

Second clinic: -8.00 and -7.50

The cylinder values were also quite different:

First clinic: around -2.25 in both eyes

Second clinic: around -3.00 and -2.50

Because of these measurements, the first clinic recommended PRK, while the second recommended ICL.

What confuses me is that I understand subjective refraction tests can vary somewhat, and I wouldn't be too concerned if the difference was 0.25 or even 0.50 diopters. But a full 1.00 diopter difference seems quite large.

The first clinic took their time with the examination, carefully confirmed my responses, and gradually increased the power until I could read everything clearly. The second exam felt much quicker (around 5 minutes), the room wasn't very dark, and the vision chart even seemed closer than what I'm used to. Because of that, I currently trust the first clinic's measurements more.

However, I can't really go back to the first clinic because they were quite firm that PRK was the appropriate option and didn't recommend ICL. During my consultation at the second clinic, the doctor explained that for PRK or other laser procedures, the combined spherical and cylindrical correction should generally stay below around 9.5 diopters. Based on their measurements, I'm right at that limit or possibly beyond it.

Even if the first clinic's prescription is the correct one, it feels like PRK would be cutting things very close. My concern is that I could end up with residual prescription and need glasses again relatively soon after surgery, which is exactly what I'm trying to avoid.

That's why I'm currently leaning toward ICL, assuming I'm a suitable candidate. At the same time, the large difference between the two prescriptions is making me nervous because I need to order lenses soon, and I don't want to proceed based on inaccurate measurements.

Has anyone experienced such a large difference between prescriptions from two clinics? Is a 1.00 diopter difference in subjective refraction normal, or should I be seeking another opinion before moving forward with surgery?

Any advice or experiences would be greatly appreciated.

Hey everyone,

I am considering getting eye surgery and am looking for recommendations for good eye surgeons or refractive consultants in Hyderabad.

To give you some context: I visited a doctor a few years ago who conducted some tests, looked at the results, and mentioned that LASIK wouldn't be viable for my power and corneal thickness, so ICL would be the best option. However, he didn't really discuss it further with me regarding the pros, cons, or details of my eye health, and went straight to fixing a surgery date.

Because of that, I want to get a fresh start with a doctor who focuses a lot on patient communication. I am looking for a consultant who:

--Will re-run the necessary tests from scratch to see where my eyes stand today.

--Will actually sit down with me, go through the fresh results, and re-evaluate my case thoroughly.

--Will take the time to walk me through the pros, cons, and the best course of action even if that means advising me to wait it out.

--Will give me an honest, unbiased opinion on whether surgery is genuinely the right decision for my eyes.

I’ve heard good things about LV Prasad Eye Institute (LVPEI), but I am completely open to any hospital or individual consultants across Hyderabad as long as the doctor is known for being patient, communicative, and thorough.

--Has anyone here gotten ICL done in Hyderabad? Who was your surgeon, and how was your pre-op consultation experience with them?

--Are there specific doctors known for taking the time to explain test results and answer questions rather than rushing into scheduling the procedure?

Any specific doctor names or personal experiences would be incredibly helpful.

Thanks in advance!

Hey everyone,

I'm thinking about getting eye surgery soon and could really use some opinions or experiences from people who've been through something similar.

I've worn glasses since I was a kid, and my eyesight seemed to get worse every year until recently, when it finally stabilized. I went for a consultation and was told I'm not a candidate for LASIK because my corneas are too thin, but I am eligible for ICL surgery.

My current prescription is:

• Left eye: SPH -7.25, CYL -1.75
• Right eye: SPH -7.75, CYL -2.50

The problem is that after looking up ICL experiences online, I immediately came across a bunch of negative stories, and now I'm seriously second-guessing myself.

I don't know anyone personally who's had any kind of eye surgery, so I don't really have anyone to ask. Without my glasses, I can barely see anything. I always carry a spare pair when I go out because if something happens to my glasses, I'm basically helpless. I have to be ridiculously close to a screen to read comfortably without them.

I've seen a lot of posts from people who had prescriptions of -10 or even higher before surgery, but not many around my range. I'd love to hear from people with similar prescriptions who got ICL. Do you feel it was worth it?

One thing that worries me is that my job involves staring at a computer for 8–10 hours a day, and I'm also under bright LED office lights most of the time. I've read a lot about halos, glare, headaches, and other side effects, and honestly, that's what's scaring me the most. Headaches would be especially rough given the amount of screen time I have.

For anyone who's had ICL, especially with a prescription similar to mine, how was your experience? How noticeable were halos and glare, especially at night or when working on a computer? Did they improve over time? Any regrets, things you wish you knew beforehand, or reasons you'd recommend (or not recommend) going through with it?

Also, if anyone had a prescription in the -6 to -9 range, thin corneas, and works long hours in front of screens, I'd be especially interested in hearing how things turned out for you.

Thanks in advance!

Edit: A little extra context: I had a lazy eye when I was younger and started wearing corrective glasses because of it. Ever since then, my prescription seemed to get worse year after year until it finally stabilized recently. Not sure if that matters when it comes to ICL, but figured I'd mention it.
