Learn With Tamil Lyrics on Instagram: "LASIK is a laser procedure that permanently reshapes the cornea to correct nearsightedness, farsightedness, and astigmatism. A surgeon creates a small corneal flap, uses an ultraviolet laser to remove precise amounts of tissue, and replaces the flap. This improves how light focuses on the retina, often eliminating the need for glasses.👁️ #eye #tamil #infovideo #surgery"
