Photorefractive keratectomy is a type of refractive surgery to correct nearsightedness, farsightedness, and astigmatism.
Laser-assisted in-situ is designed to correct multiple levels of nearsightedness, farsightedness, and astigmatism. LASIK is a surgical procedure using laser energy to reshape the cornea for better eyesight. In some cases it reduces and in some cases it entirely eliminates the need for eyeglasses or corrective lenses. This surgery is refractive based surgery that changes the shape of the dome-shaped transparent tissue (cornea) at the front of your eyes, with LASIK laser vision correction you may never have to wear glasses or contacts again!
LASIK candidates must be over 18, and they should be careful that they have no diseases or health issues of the eyes, like cataracts or glaucoma. Also, candidates must have had a stable vision prescription for at least a year.
