The use of computer technology in medical science has been expanding during the past couple of years. Laser eye surgery has become more and more popular, while non-laser procedures also have improved. Though many people think that LASIK is the sole type of refractive surgery, there are in fact various types of eye surgery for correcting vision.

Non-laser Eye Surgery

These surgical procedures involve enhancing vision by cutting into the surface of the eye, reshaping the cornea or utilizing low heating waves. Astigmatic keratotomy incisions, intraocular lenses and implantable contact lenses are among the most frequent non-laser eye surgery procedures.
