Physics in Medicine and Biology, 1977
The laser energy required to achieve an iridectomy in the human eye is calculated as a function of laser beam radius and pulse duration. Two widely different models of the stromal pigment distribution are used in order to embrace the range of coloured irides encountered in practice.

Laser Iridectomy Therapy of Glaucoma
JAMA Ophthalmology, 1973Seventeen iridectomy attempts were performed on 16 eyes using ruby, neodymium, and argon lasers. None of these was found suitable for iridectomy formation in blue eyes. Ruby wavelength was found to be the wavelength of choice in brown eyes, yielding a patent iridectomy in six out of six attempts. Attempts with neodymium and argon were disappointing. No

Corneal Decompensation After Argon Laser Iridectomy
JAMA Ophthalmology, 1988Five eyes of three patients developed generalized corneal decompensation after undergoing argon laser iridectomy for angle closure glaucoma. Factors possibly associated with corneal decompensation include episodes of angle closure glaucoma with pressure elevations and inflammation, corneal guttate, diabetes, and the need for multiple treatments ...

An “Exploding Cataract” Following Nd:YAG Laser Iridectomy
Ophthalmic Surgery Lasers and Imaging Retina, 2003A case of an “exploding” cataract (an iatrogenic posterior capsular rupture) following Nd:YAG laser iridectomy is described. Rapid cataract development was observed in the right eye of a 76-year-old woman following an iridectomy. B-scan ultrasonography documented cortical debris in the vitreous cavity.

Histopathology of Neodymium:YAG Laser Iridectomy in Humans
Ophthalmology, 1985Fifteen peripheral iridectomy specimens were obtained, with informed consent, from patients with primary narrow angle glaucoma, after previous neodymium:YAG (Nd:YAG) laser iridectomy. The iridectomies were performed three hours to ten weeks after laser application.

Corneal Decompensation After Argon Laser Iridectomy
Archives of Ophthalmology, 1989To the Editor. —We have had the pleasure of reading the article by Schwartz et al 1 in the November 1988 issue of theArchivesregarding corneal decompensation after argon laser iridectomy. Although all of us have seen corneas occasionally decompensate after an attack of angle closure glaucoma or after surgical procedures, our experience suggests less ...

Thermoelastic analysis of laser iridectomies
Journal of Biomedical Engineering, 1989We have attempted to derive the stress-strain-temperature relationships of the iris stroma subject to a restrictive thermal burn from a laser. The corresponding displacement equation embodies the mechanical impulses due to this thermal insult. This thermoelastic analysis of laser iridectomy attempts to describe the mechanism involved in the surgical ...

Laser Iridectomy in the Management of Chronic Angle-Closure Glaucoma
American Journal of Ophthalmology, 1984Nineteen eyes of 16 patients (12 men and four women ranging in age from 41 to 75 years) underwent laser peripheral iridectomy for treatment of uncontrolled chronic angle-closure glaucoma (25 to 62 mm Hg). Five of eight eyes (62.5%) with glaucomatous cupping but full visual fields attained postiridectomy intraocular pressures of less than 22 mm Hg with ...
