Changes in Axial Length after Cataract Surgery in Children: A 2-years-follow-up of a Prospective, Randomized Study

Purpose: The role of intraocular lenses in management of pediatric cataracts remains controversial, although it is becoming a more widely accepted and commonly used method. However, evidence concerning the role of IOLs in regulating ocular growth is contradictory. We present a longitudinal study of the biometric changes two years after cataract surgery and IOL-implantation in children. Moreover, we compare two different surgical methods.
Method: 26 eyes of 18 children aged 29 months to 11 years underwent cataract extraction and posterior chamber IOL implantation. 14 eyes had an in the bag IOL-implantation with anterior vitrectomy (method A) and 12 eyes underwent optic capture of the IOL without anterior vitrectomy (method B). Preoperatively and postoperatively axial length was measured at intervals. Comparison between the observed changes in axial length and the expected pattern of postnatal growth was achieved with the healthy contralateral eyes of our patients with unilateral cataract. Statistical analysis was performed with the t-test.
Results: Comparison of the axial length growth between the cataract eyes treated with IOL-implantation and healthy eyes indicated no significant difference (P = 0.72). Moreover, subgroup analysis of the two different surgical methods revealed no significant difference of postoperative axial length growth (P
