Comparison of visual outcome in monofocal versus multifocal iol

Introduction: The goal of cataract surgery has changed from mere restoration of vision to attaining spectacle independence. While the introduction of phacoemulsification and foldable monofocal IOLs led to spectacle free vision only for distance, multifocal IOLs led to complete spectacle independence for both distance as well as for near, but with its own set of drawbacks. Material and Methods: A prospective interventional study consisting of 50 eyes of 50 patients divided into two groups of 25 each. Group A underwent monofocal IOL implantation while group B underwent multifocal IOL implantation. Results: Group A didn’t experienced glare, haloes, reduction of contrast sensitivity and complete spectacle independence. Group B experienced glare and haloes in 12 (48%) patients, reduction of contrast sensitivity in 25 (100%) patients, and spectacle independence in 12 (48%) patients. Conclusion: Multifocal IOLs can lead to complete spectacle independence but associated with disturbing phenomenon of glare, halos and reduction in contrast sensitivity. Further improvement in design of multifocal IOLs is suggested.
