Quizplus · Accepted Answer

Laser-assisted in situ keratomileusis, or LASIK, is a surgical procedure that uses a laser to remove small portions of the cornea to reshape it and improve vision. It is a common procedure for correcting nearsightedness, farsightedness, and astigmatism. Iridectomy involves removing a small part of the iris, and is not used for correcting vision. Penetrating keratoplasty is a procedure where a damaged cornea is replaced with a donor cornea, and is not used for changing the curvature of the cornea. Retinitis pigmentosa is a genetic eye disorder that affects the retina, and is not treated with corneal surgery.
