A population of 250 age-matched cataract patients was studied to determine if hospitalization was required for cataract extraction. The success of the procedure was not jeopardized if immediate ambulation was effected and postsurgical care carried out entirely on an ambulatory basis in a nonhospital environment. The cost containment potential of this approach cannot be readily achieved in the face of existing regulatory systems and insurance requirements.

Pupillary block glaucoma is a potential complication of implantation. Early recognition and prompt medical therapy will generally successfully treat the condition. In some instances surgical treatment is required if medical therapy is inadequate. Laser iridectomy and laser photomydriasis are other alternatives to surgical therapy. This case reports successful treatment of pseudophakic pupillary block glaucoma using laser photomydriasis.

We designed a glass and polyimide iris-plane, iris-clip intraocular lens. It is sterilized in the autoclave and weighs approximately 6 mg in water. The optic is 0.3 mm thick for a 19-diopter lens and the flexible haptic is 0.05 mm thick. Two identical haptics and the optic are joined mechanically to form the intraocular lens. The round spatula-like portion of an insertional instrument secures the intraocular lens by passing through two opposing flexible haptic loops and behind the optic. Fluid or air is irrigated through the cannula as the implant is inserted in order to protect the endothelium.

Intraocular lenses, or their components of various weights and designs, were placed on and within the viterous of fresh human autopsy eyes. All devices were supported on the surface of the intact viterous and within the formed vitreous. All sank promptly through the disorganized vitreous. Advice against anterior vitrectomies at the time of implant surgery is offered.
