Laser in situ keratomileusis, or LASIK, is a laser eye surgery that is used to correct astigmatism, farsightedness, and nearsightedness. LASIK is used to change the shape of the cornea, which is a transparent part covering the front part of the eye. A special kind of laser known as excimer laser is used during this surgery to improve vision and treat refractive errors.
Cataract surgery is generally not performed on both eyes together. In hospitals and surgery centers with advanced technology, the gap between the surgeries of the two eyes can be between 5 to 15 days. During this period, elderly patients find difficulty in driving. Visual acuity is generally tested after a cataract surgery, but what should also be tested, for issuing a drivers license, is the contrast sensitivity in both the eyes.
