Primary intraocular lens implantation in infants: complications and visual results.

PURPOSE To evaluate the complications and visual results in a consecutive series of patients having cataract extraction with intraocular lens (IOL) implantation in the first year of life. SETTING St. Erik's Eye Hospital, Stockholm, Sweden. METHODS This retrospective study comprised 28 children (31 eyes) who had cataract surgery with primary IOL implantation. RESULTS The median age at surgery was 2.5 months (range 8 days to 10 months). The median follow-up was 36 months. Two newborns with persistent fetal vasculature (PFV) who had surgery at 8 days and 17 days, respectively, developed intraoperative vitreous hemorrhage; a retinal detachment developed in 1 of the eyes. Intraocular lens luxation occurred in 2 infants with PFV. Seventy percent of eyes developed opacification of the visual axis that required additional surgery. Chronic glaucoma developed in 2 eyes and transitory glaucoma in 1 eye. Two of the glaucoma cases occurred in eyes with PFV. In 7 eyes of 4 infants with bilateral cataract, the median visual acuity was 20/63 (range 20/25 to 20/100). In 12 infants with unilateral cataract without PFV, 7 achieved a visual acuity between 20/32 and 20/200 (median 20/63), 4 achieved counting fingers (CF), and 1 achieved light perception. In 12 eyes with PFV, 2 achieved a visual acuity of 20/200 and the rest achieved CF or worse. CONCLUSIONS After-cataract with membrane formation was the main complication in infants with primary IOL implantation. The glaucoma incidence was low at the last follow-up.
