A study of 200 cases of anterior chamber implants.

In a series of 200 eyes with Choyce or Leiske style anterior chamber implants followed for an average of 19 months, final visual acuity averaged 20/30. Eighty-four percent of patients were 20/40 or better and 8% 20/100 or worse at the end of the period of observation. Cystoid macular edema occurred in 17% with most cases occurring during the first seven months. Visual loss averaged two lines and duration averaged eight months. All but one patient with adequate follow-up recovered. Cystoid macular edema appeared to be more frequent in patients who were "blinkers." The incidence of "new" glaucoma in this study was 2%. Ovalling of the pupil occurred in 46% of eyes, more frequently late than early. Early development of ovalling was more likely to be associated with imperfect implant positioning than was late. Imperfect implant position occurred in 40% of cases and inadequate early fixation resulting in propellering or rotation in 16%. Rotation was not associated with imperfect implant position. No cases of severe iritis were encountered. Pigment dispersion and vitreous herniating anterior to the optic were observed in a few eyes. No cases of corneal decompensation occurred although two eyes had minor to moderate changes. The incidence of subsequent procedures was a low 6%, helping to contribute to the high ratio of patient satisfaction. Mild tenderness and glare were the chief postoperative symptoms.

A first year's experience with intraocular lens implantation.

A microsurgical modification of Binkhorst's "open sky" technique of extracapsular cataract extraction was developed for intraocular lens implantation. Clear visualization of both anterior and posterior capsule is stressed and risky aspiration is minimized. Thirteen cases operated upon in the first year are described. Synechiae to the haptics occurred when mydriasis was not prompt. All but one obtained useful naked acuity. Binocularity depended chiefly upon the acuity of the opposite eye. Pre-calculation of lens power reduced the spread of postoperative refractive errors although deviation was greater than expected and myopia overaccentuated. High astigmatic errors occurred in three patients.
