The results of extracapsular cataract extraction with a Shearing posterior chamber lens implant 34 to 40 months after surgery.

A series of 300 consecutive extracapsular cataract extractions with a Shearing posterior chamber lens implant (plus 13 with a surgical complication necessitating another kind of lens implant or no implant) was evaluated 34 to 40 months after surgery, except for those who died before this time (21 patients) and those lost to follow-up (15 patients). Ninety-one percent of the 264 patients who were examined achieved 20/40 or better visual acuity. Ninety-one percent of the 300 patients (those examined plus those who died and those lost to follow-up according to their last recorded examination) achieved 20/40 or better visual acuity. This series was compared to a previously reported series of 300 consecutive intracapsular cataract extractions with a Binkhorst iris clip lens implant examined 34 to 40 months after surgery.
