Abstract :

Purpose: To evaluate the near visual performance of Ultrathin and standard monofocal Foldable intraocular lenses after phacoemulsification. Setting: St.Stephen’s hospital, Department of Ophthalmology, Tis Hazari, Delhi, India Methods: Forty (40) patients were enrolled and randomized into two groups of 20 eyes in each group to the type of intraocular lens – Ultrathin or foldable. All patients underwent routine phacoemulsification surgery. Both the groups were evaluated for visual acuity including distance and near vision, amplitude of accommodation and contrast sensitvity upto 3 months after surgery Results: Postoperative distance corrected near vision was better in Ultrathin intraocular lens group than in Foldable Intraocular lens group. Postoperative average distance corrected near correction required was less in Ultrathin intraocular lens compared to Foldable intraocular lens but was not of statistical significance. The amplitude of accommodation as measured by the two subjective methods was not significantly different between the two groups. In our study, contrast sensitivity increased during the follow up period of 3 months in Ultrathin lens. Conclusion: This study shows that thinner intraocular lenses can provide better restoration of near vision post cataract surgery although amplitude of accommodation was not significantly different between the two intraocular lenses.
