Abstract
To report the prevalence of anisometropia at age 5 years after unilateral intraocular lens (IOL) implantation in infants.Prospective randomized clinical trial METHODS: Fifty-seven infants in the Infant Aphakia Treatment Study (IATS) with a unilateral cataract were randomized to IOL implantation with an initial targeted postoperative refractive error of either +8D (infants 28 to <48 days of age) or +6D (infants 48-210 days of age). Anisometropia was calculated at age 5 years. Six patients were excluded from the analyses.Median age at cataract surgery was 2.2 months (IQR, 1.2, 3.5 months). The mean age at the age 5 year follow-up visit was 5.0 ± 0.1 years (range, 4.9 - 5.4 years). The median refractive error at the age 5 year visit of the treated eyes was -2.25 D (IQR -5.13, +0.88 D) and of the fellow eyes +1.50 D (IQR +0.88, +2.25). Median anisometropia was -3.50 D (IQR -8.25, -0.88 D); range (-19.63 to +2.75D). Patients with glaucoma in the treated eye (n=9) had greater anisometropia (glaucoma, median -8.25 D; IQR -11.38, -5.25 D vs. no glaucoma median -2.75; IQR -6.38, -0.75 D; p=0.005) CONCLUSIONS: The majority of pseudophakic eyes had significant anisometropia at age 5 years. Anisometropia was greater in patients that developed glaucoma. Variability in eye growth and myopic shift continue to make refractive outcomes challenging for IOL implantation during infancy.
