N2 - Purpose To report the prevalence of anisometropia at age 5 years after unilateral intraocular lens (IOL) implantation in infants. Design 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 +8 diopters (D) (infants 28 to <48 days of age) or +6 D (infants 48–210 days of age). Anisometropia was calculated at age 5 years. Six patients were excluded from the analyses. Results Median age at cataract surgery was 2.2 months (interquartile range [IQR], 1.2, 3.5 months). The mean age at the age 5 years follow-up visit was 5.0 ± 0.1 years (range, 4.9–5.4 years). The median refractive error at the age 5 years 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 +2.75 D. 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 = .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.
