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.
