Long-term Results and Complications using Scleral-fixated Posterior Chamber Intraocular Lenses

ABSTRACT

The scleral fixation of a posterior chamber intraocular lens is known to be a technique for managing cataract, aphakia, lens dislocation, pseudophakic bullous keratopathy with incomplete zonular or capsular support. We performed a retrospective review of longterm results and complications of 86 patients(103 eyes) who had a minimum of 12 months follow-up after scleral fixation of a posterior chamber intraocular lenses. At the last examination, mean postoperative corrected visual acuity is 0.7 +/- 0.28 and 62 eyes(57.4%) had a vision of 0.8 or better. Especially in aphakia, postoperative corrected visual acuity was significantly improved. The complications related to scleral fixation were exposed scleral fixation suture, glaucoma, cystoid macular edema, subluxation of intraocular lenses, retinal detachment, herpetic keratitis, vitreous hemorrhage and vitreous opacity. The other factors influenced on visual acuity were age-related macular degeneration, optic atrophy, diabetic retinopathy and clinical significant macular edema, and corneal opacity. Though these longterm results suggest that overall prognosis for visual acuity is quite good, careful assessment preoperatively and proper management are important.
