Incidence of Pseudophakic Dysphotopsia: Comparison of Two Intraocular Lenses

Hasanain Shikari

Purpose:
Incidence of Pseudophakic Dysphotopsia after uneventful Phaco Surgery with Acrysof IQ SN60WF and Tecnis ZCB00 Intraocular lens is related to design features.

Methods:
84 eyes of 68 patients were assessed. Patients were evaluated using a telephonic questionnaire between 3-6 months post surgery. Responses were rated on a scale from 0-4 (none-severe symptoms).

Results:
45.09% of eyes with IQ presented with various grades of dysphotopsia as against 27.4% eyes with ZCB00. 13.7% eyes with IQ were severely dysphotopic versus 3% with ZCB00.
27.4% eyes with IQ experienced night-time glare as against 18.2% eyes with ZCB00. 5% eyes with IQ suffered severe glare versus none with ZCB00.

Conclusion:
Design features of the Tecnis ZCB00 lead to less dysphotopsia and night-time glare as compared to Acrysof SN60WF.
