Abstract
Congenital cataract is one of the major causes of visual deprivation in pediatric population due to factors like need of early surgery, risk of amblyopia development, demanding surgical skills due to small dimension of infant eye with a small capsular bag, decreased scleral rigidity. Both surgical aphakia and cataract are equally amblyogenic if not corrected in time. Various modalities like spectacle, contact lens, and primary IOL implantation are available for correction of aphasia. Nowadays primary IOL implantation has been widely used with favorable results in children older than two years; however, there are problems such as difficulty in selecting the appropriate dioptric power of the IOL, due to early phase of rapid eye growth in children less than 2 year. Also, current theoretical and regression intraocular lens power prediction formulas are largely based on adult eyes at axial lengths, anterior chamber depth, and keratometric values much different than those seen in infants. The small dimension of infant eye, and increased tissue reactivity leading to excessive postoperative inflammation make IOL implantation technically more difficult in these patients. With the invent of microsurgical techniques, instrumentation and increasing evidence of successful primary intraocular lens implantation in first two years of life, this appears to be new ray of hope in patients with congenital cataract. The aim of the present study was to evaluate outcome of primary IOL implantation in the first 2 years of life.
