BOSTON — An aphakic lens implant may offer spectacle-free vision to patients with ectopia lentis, according to a speaker here.

Lensectomy may spare the patient from lens-induced uveitis or glaucoma, but remains technically challenging, Catherine Cleary, MD, said at the annual meeting of the American Society of Cataract and Refractive Surgery. However, she said, lensectomy has previously been associated with a rate of retinal detachment as high as 17% in the published literature.
In a series of 24 eyes of 13 pediatric patients who underwent early lensectomy with a mean follow-up of 11 years, Dr. Cleary said that no retinal detachments have been noted. Because children have a soft, mobile sclera and because collagen degeneration is often less advanced in the pediatric age group, early lens removal may reduce the risk of retinal detachment by reducing tractional forces from the mobile lens, Dr. Cleary said.
In a series of eight eyes of five patients implanted with a three-piece iris claw lens, vision improved in all but one patient. Postoperative uncorrected visual acuity was greater than 6/12 in all eyes, Dr. Cleary said. Mean endothelial cell loss was 7.7% after a mean 34 months of follow-up, which is similar to the 10% rate reported in the published literature, Dr. Cleary said.
