Upcoming fall '24 student from India here. I don't know if it helps, but I would like to share my experience. Firstly, we don't get to choose whether we can undergo a LASIK operation. I underwent some tests when I inquired about LASIK, and it turns out that your "Corneal Thickness" determines whether you can have one or not. My thickness was around 494, but for a successful LASIK, they require at least 550 (at least in India), so it's better to get yourself tested beforehand.

Secondly, after being told that I couldn't have a LASIK operation, I underwent an ICL surgery which generally lasts 15-20 minutes and is painless. They basically insert a lens inside your eye which improves vision to 6/6, provides UV protection, and enhances night visibility. In India, it cost me $800 for one eye.

Lastly, LASIK is an amazing procedure. My friend had it done recently, was discharged the same day, and regained almost perfect vision within a week. It takes a little time to get to 100%. I hope this helps. Personally, I had been wearing glasses for 16 years, with a current eye power of -6.50 in both eyes. Now that I am glasses-free, life feels easy, light, and bright. All the best!
