Non-laser Eye Surgery

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

Astigmatic Keratotomy Incisions

This procedure is used to correct mild astigmatism. Bulgy regions of the retina are mesmerized using a blade. Many patients undergo such a remedy together with other types of eye surgery. However, it is now less frequently used than laser eye surgical procedures, such as PRK or LASIK.
