Abstract PURPOSE: After infantile cataract surgery, axial elongation, induces a myopic shift that cannot be fully compensated by corneal flattening and the rate is unpredictable owing to the non-linear growth of the eye. The current prospective study assesses the myopic shift and visual outcomes in children undergoing cataract surgery in infancy over a follow-up period of 5 years. MATERIALS AND METHODS: A prospective study conducted at a tertiary eye care center to evaluate the five-year myopic shift, refractive and visual outcomes in infants, who underwent surgery for congenital cataract in infancy. The visual acuity, myopic shift and biometric changes are compared between the aphakia and pseudophakia group. RESULTS: The mean best-corrected visual acuity (BCVA) recorded in logMAR at 5 years for aphakia group was 0.92±0.44 and for pseudophakia group was 0.66±0.42. (pvalue: 0.002102). The myopic shift was noted to be -5.9+/-5.16 in the aphakia group whereas it was -9.01+/- 3.11 in the pseudophakia group ( P value= 0.002101) at 5 years after surgery for infantile cataract. CONCLUSION: IOL implantation in eyes of infants undergoing cataract surgery is feasible in eyes that strictly satisfy the pre-operative inclusion criteria and the visual outcomes in these eyes are better compared to aphakia group at 5 years follow up. Eyes with primary IOL implantation had a higher myopic shift compared to ones without primary IOL implantation. Eyes undergoing primary IOL implantation, need higher under correction compared to the current available formulae.
