Explantation of silicone plate haptic intraocular lenses.
The stress on small self-sealing incisions in cataract surgery has resulted in the increased use of foldable intraocular lenses (IOL). Plate haptic silicone IOLs implanted with the help of an injector require extremely small incision lengths and are extensively used. The authors discuss difficulties in explanting such lenses, especially in inflamed eyes. Two patients who underwent plate-haptic silicone IOL explantation for postoperative bacterial endophthalmitis are described. Plate haptic IOLs have a tendency to dislocate posteriorly because of poor capsular fixation and increased posterior bowing. Enlarging a small rhexis prior to attempting explantation of these lenses reduces this complication. Difficulties inherent in explanting plate haptic silicone IOLs in inflamed eyes are discussed, along with suggestions to overcome them.
