Congenital Cataract – the Growth of the Eyeball after the PC IOL Implantation

Overview

The authors followed the influence ofPCIOL(posteriorchamber intraocular lens)implantation in congenital cataract to the growth of the eyeball (six bilateralcataracts and 6 monolateral cataracts). The development of the eye growth wascompared to the 6 healthy eyes of patients of this group. The intraocular lensimplantation was performed at the age of 1 to 5.5 year, in average at the age of 3years. The follow up period was 4 to 7 years, mean 6 years. In operated, as well asin non-operated eyes, an equal average growth of the eyeball 0.2mmper year wasdetected. All operated eyes were slightly hypermetropized according to the physiologicalvalues of growth of healthy eyes. The absolute mean deviation fromemmetropia was 1.8 diopters. The author established the suitability of intraocularlens implantation in small children because of positive influence to the growth aswell as to the final visual acuity, which ranged from 0.05 to 1.0, mean 0.4.
