AIM: To observe the eye development and complications after primary intraocular lens implantation(IOL)in infantile cataract.

METHODS: The postoperative complications, corrected vision, refractive state, ocular axis of 46 patients(92 eyes)with congenital cataract treated by IOL implantation within 10y were retrospectively analyzed.

RESULTS: Five eyes(5%)had postoperative complications. In this study, the average corrected visual acuity was 0.40±0.10 at 3a follow-up after surgery, 0.51±0.01 at 5a follow-up after surgery, and 0.71±0.01 at 7a follow-up; The axial length of the eyes was 20.04±0.02mm at 3a after surgery, 22.09±0.09mm at 5a after surgery, and the axial length of the eyes was 22.96±0.06mm at 7a after surgery; The mean refractive state(equivalent spherical lens degree)at 3a after surgery was observed to be +5.37±0.12 DS, +3.20±0.20 DS at 5a after surgery, and +0.92±0.20 DS at 7a after surgery.

CONCLUSION: The appropriate surgical strategies can give safely and effectively opportunity for the patients with infantile cataract, which also have relatively normal refractive development.
