Explantation of a foldable silicone intraocular lens.

PURPOSE: We used a novel technique for explanting an improperly oriented silicone intraocular lens. METHODS: The elastomeric property of silicone was used to deform the optic and remove the intraocular lens in one piece. RESULTS: We explanted a flexible intraocular lens without compromising the integrity of the original wound, posterior lens capsule, or corneal endothelium. CONCLUSIONS: The technique offers a superior means of intraocular lens explantation while retaining the benefits of small-incision cataract surgery.

Corneal complications of cataract surgery.

Recent advances in cataract surgery have reduced the incidence of corneal complications. Review of the current literature reveals a trend toward early visual rehabilitation and minimization of postoperative astigmatism by careful selection of incision type and location for small-incision cataract surgery. Since the introduction of intraocular lenses, endothelial cell loss has been a concern. Preservation of corneal endothelial cell function continues to be a major goal as cataract surgery continues to evolve. Recent studies have been undertaken to determine the effect of incision location and size on endothelial cell loss. Several reports on iatrogenically induced corneal decompensation are of interest as this complication can be avoided if proper precautions are taken. Although improvements in surgical technique have lead to a decreased incidence of Descemet's membrane detachments and of epithelial and fibrous downgrowth, early recognition and intervention are imperative.
