Excimer Laser Application For Cataract Surgery

Proceedings of SPIE, 1988
The ablation threshold of bovine lenses was determined for excimer laser radiatiF at 308 nanreters. The ablation th5eshold for bovine lenses was approximately 0.6J/cm +/-0.1J/cm , for cortex and 1J/cm for nucleus. The threshold for bovine nucleus was higher than the threshold for cortex and difference was statistically significant at the 0.05 level ...

Studies in fiber guided excimer laser surgery for cutting and drilling bone and meniscus [PDF]

Lasers in Surgery and Medicine, 1991
Our experiments on transmitting high-power excimer laser pulses through optical fibers and our investigations on excimer laser ablation of hard tissue show the feasibility of using the excimer laser as an additional instrument in general and accident ...

ArF 193 nm Excimer Laser Corneal Surgery as a Possible Risk Factor in Cataractogenesis

Experimental Eye Research, 1994
It was evaluated whether ArF 193 nm excimer laser corneal surgery represents a risk factor in cataractogenesis. For this purpose, 20 male albino rabbits underwent a photorefractive keratectomy and biochemical analyses on aqueous humour (hydrogen peroxide,

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 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 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.

Evolution of excimer laser corneal surgery

Journal of Cataract and Refractive Surgery, 1989
Interest in the potential of the excimer laser for refractive surgery was generated by a series of experiments performed in IBM's T.J. Watson laboratories. The development of photoablative decomposition was applied to corneas with immediate implication for corneal refractive control.

The Characteristics of Excimer Laser Refractive Surgery Candidates

Eye & Contact Lens: Science & Clinical Practice, 2018
Purpose: To determine the demographic and refractive characteristics of excimer laser refractive surgery candidates in Iran. Methods: This was a cross-sectional study between 2010 and 2014. All information was collected from 28 centers randomly selected from 12 provinces.
