Excimer Laser Surgery of the Cornea

American Journal of Ophthalmology, 1983
The excimer laser, which produces light in the far-ultraviolet portion of the spectrum, allows precise removal of corneal tissue through a photochemical laser-tissue interaction. This interaction is not thermal and does not involve optical breakdown; rather, it directly breaks organic molecular bonds without tissue heating.

Excimer laser surgery for keratoconus

Journal of Cataract and Refractive Surgery, 1998
To determine whether there is increased risk associated with excimer laser surgery of primary keratoconus.Department of Ophthalmology, County Council Hospital, Ryhov, Jönköping, Sweden.Twenty-four eyes in 23 patients with keratoconus had photorefractive keratectomy (PRK) to reduce the steepness of the cone.

Excimer Laser Filtration Surgery

American Journal of Ophthalmology, 1995
In order to remove precisely scleral tissue overlying Schlemm's canal with minimal trauma as an outpatient procedure under local anesthetic, we used a VisX Twenty/Twenty excimer laser.We performed excimer laser filtration in three enucleated pig eyes, seven enucleated human eyes, and seven eyes of seven patients with severe glaucoma.
