Abstract

PURPOSE
To analyze the clinical features and the long term visual results of children with ectopia lentis after lensectomy. METHODS: Enrolled in this study were 79 eyes of 43 patients who were operated on and followed up for at least 3 years. We performed a retrospective analysis of the patient records. RESULTS: The mean age at diagnosis was 4.6 years, mean age at surgery was 5.7 years and average follow-up was 7.1 years. Of the 43 patients with bilateral ectopia lentis, 7 underwent monocular surgery. The mean age at diagnosis was higher and mean postoperative BCVA was significantly lower in the monocular surgery group than in the binocular surgery group. All eyes showed reduced hyperopia for 5 years postoperatively, but the reduction rate of the monocular operated eyes was significantly lower than that of the binocular operated eyes (P<0.05). No complication occurred during surgery and 1 eye (1.3%) with Marfan syndrome showed retinal detachment 9 years after surgery. CONCLUSIONS: Surgical treatment of ectopia lentis was safe and showed good visual outcomes after 7.1 years of follow-up. Nevertheless, consideration must be given to the possibility of amblyopia due to the difference of the degree of dislocation between the two eyes.
