PHACOEMULSIFICATION OF DISLOCATED LENS AND SUTURE FIXATION OF INTRAOCULAR-LENS USING A PERFLUOROCARBON LIQUID

The objective was to describe a new surgical technique to manage a pos teriorly dislocated crystalline lens. Four patients with posteriorly d islocated lenses were studied. Two patients had dislocated lenses seco ndary to trauma, 1 had undergone retinal detachment surgery, and 1 had an idiopathic lens dislocation. Pars plana vitrectomy was carried out on all 4 eyes, followed by an injection of perfluoro-n-octane to floa t the lens off the retina. The lens was phacoemulsified through a limb al incision, and an intraocular lens was positioned in the ciliary sul cus with suture fixation. Perfluoro-n-octane was replaced by a balance d salt solution. Postoperative visual acuity ranged from 1.0-1.5. Tran sient choroidal detachment and hypotony were observed in 3 eyes in the early postoperative period. Postoperative ocular hypertension was not ed in 2 eyes and was well-controlled with topical antiglaucoma agent. These results indicate that limbal lensectomy of a posteriorly disloca ted lens using perfluorocarbon liquids is a beneficial and relatively safe method. (C) 1998 Japanese Ophthalmological Society.
