Following are the main surgeries that is being practiced in ophthalmology
Refractive Surgeries:Glasses or contact lenses correct refractive errors such as nearsightedness, farsightedness, and astigmatism. These surgeries are predominantly done to remove specs and contact lens, they are cosmetic oriented surgeries.
LASIK (laser assisted in situ keratomileusis): A doctor cuts a flap in the cornea with a tiny saw. A laser reshapes the cornea’s surface, improving nearsightedness. Used for correcting myopia, hyperopia, and astigmatism.
Radial keratotomy (RK): A series of small incisions are made in the cornea to correct nearsightedness. Radial keratotomy is rarely used today.
Photorefractive keratectomy (PRK): A doctor rubs off the surface of the cornea, and then uses a laser to improve nearsightedness. The cornea then heals and grows back.
LASEK (Laser Epithelial Keratomileusis): Similar to LASIK, but no flap is cut in the cornea. Instead, the topmost layer of cornea cells is pulled off, allowing the laser to reshape the cornea.
Laser photocoagulation: A doctor uses a laser to burn blood vessels in the retina that are leaking or growing abnormally. Laser photocoagulation is most often done for diabetic retinopathy.
The cloudy cataract is removed from the lens and replaced by a man made lens (IOL- Intra Ocular Lens).
