NO cure for myopia. Nothing to make it stop. World epidemic of myopia due to computers, iPads, iPhones, Video games, reading. Much higher rates in Asians. In 2 generations (40 years) everyone worldwide could be myopic. You will see better with contacts as the image is much bigger.
Surface lasik might be done on you. It would not get rid of all your myopia but ight change your -12 to -5 or -6. an ICL could correct all your myopia but I do not like them as they go inside the eye and have (to me) unacceptable risks. As far as RD dont do contact sports, protect against eye injury, don't do amusement thrill rides.
You cannot email me or post your email address. MedHelp.org forbids that. Yes there are many excellent cornea/refractive surgeons in India. I do not know them by name. A medical center/medical school would be a good place to look. You need a "cornea refractive surgeon" I would get at least 2-3 different opinions at different places. If you are meticulous about care and wear of your contacts there is no reason to believe you will damage your eye. Many people wear contacts for 20-30 years or more without problem. Yes surface lasik is PRK It works better for high myopes with thin corneas.
Different opinions for all reasons: price, how much myopia might be corrected, see how your personality meshes with the surgeons, which staff you like most.
