Abstract
We describe our experience correcting a cohort of infants with contact lenses in the Infant Aphakia Treatment Study.Fifty-seven infants 1-6 months of age were randomized to contact lens wear. An examination under anesthesia was performed at the time of enrollment and at approximately 1 year of age. A traveling examiner assessed visual acuity at approximately 1 year of age.Forty-two treated eyes (74 %) were fitted with silicone elastomer (SE) contact lenses; 12 eyes (21 %) with rigid gas permeable (RGP) contact lenses, and 3 eyes (5%) wore both lens types. Median visual acuity was +0.80 logMAR in both lens type-wearing groups. The mean (± SD) keratometric power of the treated eyes was 46.3±2.8 D at baseline and 44.6±2.3 D at 1 year of age for a mean decrease of 0.2±0.2 D/mo. Keratometric astigmatism of treated eyes was 1.98±1.37 D at baseline and 1.62±0.98 D at 1 year of age for a mean decrease of 0.05±0.2 D/mo. The mean RGP lens base curve at baseline was 47.62 D±2.62 D versus 47.00 D±3.50 D at 12 months after surgery. Children wearing SE lenses required a mean of 10.9 replacements (range 2-24) compared to 16.8 replacements (range 8-32) for children wearing RGP lenses. Three adverse events occurred.Contact lenses were worn successfully with relatively few adverse events by a cohort of infants with unilateral aphakia. The visual acuity results were identical independent of the contact lens material or modality. RGP lenses needed replacement more often than SE lenses.
