Correlation of Pupillary Diameter Change With Age and Anterior Chamber Depth After Cataract Surgery

PURPOSE: To assess the correlation between the change in pupil diameter, age and depth of the anterior chamber after 3 months of cataract surgery both in photopic and mesopic conditions. And study the changes of the pupillary diameter at 3 months after surgery in the two light conditions
