Objective: To describe baseline characteristics, initial postoperative refractive errors, operative complications, and magnitude of the intraocular lens (IOL) prediction error for refractive outcome in children undergoing lensectomy largely in North America.
Design: Prospective registry study of children from birth to <13 years of age who underwent lensectomy for any reason within 45 days preceding enrollment.
Participants: Total of 1266 eyes of 994 children; 49% female and 59% white.
Methods: Measurement of refractive error, axial length, and complete ophthalmic examination.
Main outcome measures: Eye and systemic associated conditions, IOL style, refractive error, pseudophakic refraction prediction error, operative and perioperative complications.
Results: Mean age at first eligible lens surgery was 4.2 years; 337 (34%) were <1 year of age. Unilateral surgery was performed in 584 children (59%). Additional ocular abnormalities were noted in 301 eyes (24%). An IOL was placed in 35 of 460 eyes (8%) when surgery was performed before 1 year of age, in 70 of 90 eyes (78%) from 1 to <2 years of age, and in 645 of 716 eyes (90%) from 2 to <13 years of age. The odds of IOL implantation were greater in children ≥2 years of age than in those <2 years of age (odds ratio = 29.1; P < 0.001; 95% confidence interval: 19.6-43.3). Intraoperative complications were reported for 69 eyes (5%), with the most common being unplanned posterior capsule rupture in 14 eyes, 10 of which had an IOL placed. Prediction error of the implanted IOL was <1.00 diopter in 54% of eyes, but >2.00 diopters in 15% of eyes.
Conclusions: Lensectomy surgery was performed throughout childhood, with about two-thirds of cases performed after 1 year of age. Initial surgery seemed safe, with a low complication rate. IOL placement was nearly universal in children 2 years of age and older. The immediate postoperative refraction was within 1 diopter of the target for about one-half of eyes.
