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.

Nd:YAG Laser Iridectomies: 100 Consecutive Cases
Ophthalmic Surgery, Lasers and Imaging Retina, 1988ABSTRACT We reviewed the patient charts of our first 100 consecutive Nd:YAG laser iridectomies. Our success rate (99%) is the same as that reported by others. Iris bleeding was not problematic. We did find that relative pupillary block may still be present with a patent but very small Nd:YAG iridectomy; that transillumination is not an ...

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.

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 Iridotomy vs Surgical Iridectomy
Archives of Ophthalmology, 1985The number of laser iridotomies in 1982 was more than four times the annual rate of surgical iridectomies performed before the laser was in common use at the Bascom Palmer Eye Institute, Miami. No single reason accounts for the increase. Only a minority of the increase is due to a 32% increase in our outpatient volume, a backlog of individuals with ...

Central Anterior Chamber Depth After Laser Iridectomy
American Journal of Ophthalmology, 1980We found the true anterior chamber depth to be unaffected by successful laser iridectomy in ten eyes treated by this modality for chronic angle-closure glaucoma. The apparent general deepening seemed to be the result of peripheral chamber deepening combined with the common use of strong cycloplegic agents, reversing the shallowing effect of ...

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.

Transactions. Section on Ophthalmology. American Academy of Ophthalmology and Otolaryngology, 1975
The argon laser and the ruby laser have been used to open the pigment layer in three cases of surgically incomplete peripheral iridectomy. The technique, its advantages and complications, were discussed. On two additional eyes, full-thickness argon laser iridectomy was unsuccessful.

Increased Intraocular Pressure Following Neodymium-YAG Laser Iridectomy
Archives of Ophthalmology, 1986To the Editor. —Peripheral iridectomy is the treatment of choice for pupillary block glaucoma and for prophylaxis of occludable iridocorneal angles. Argon laser iridectomy has fewer serious complications and has largely replaced surgical iridectomy.

Nanophthalmic Eyes and Neodymium-YAG Laser Iridectomies
Archives of Ophthalmology, 1987To the Editor. —We congratulate Karjalainen et al 1 on their interesting report of bilateral nonrhegmatogenous retinal detachments following neodymium-YAG laser iridotomies in nanophthalmic eyes. From our experience with nanophthalmic eyes and laser iridectomies, we thought that the following thoughts might be of interest: The authors mentioned that ...
