Surgery should be done only in case of cataract. Do not fall prey to anyone else’s trap. There are many quacks around you. During surgery, the surgeon removes the dirty lens and fits (implants) an intraocular lens inside the eye in its place. Of course, you may still have to wear glasses for a few days, but soon your vision will be the same as it was before cataract. The speed of surgery for cataract has now freed you from glasses. Various types of surgeries are used in the treatment of cataract.
