Purpose:

The study compares anatomic outcomes of Intra Ocular Lens(IOL) placement with two methods of centration of the capsulorhexis- scanned capsule centration and pupil centration. It is hypothesized that scanned capsule centration provides more uniform(25% better) overlap of capsulorhexis margin over IOL optic compared to pupil centration.


Study summary:

50 consecutive eyes undergoing cataract surgery will be studied. 25 eyes will have scanned capsule centration and 25 will have pupil centration. Retroillumination slitlamp photographs will be taken 10-30 days after surgery with dilated pupils. The amount of capsule overlapping the IOL will be documented. The horizontal, vertical and symmetricity of overlap will be calculated. Each group will have 20 eyes with an additional 5 eyes in each group to account for drop outs or poor quality images.


Criteria:

Inclusion Criteria: - Patients with cataracts - Same variety of IOL inserted in all eyes Exclusion Criteria: - Previous glaucoma or retinal surgery - Pupil not dilating beyond 6mm - Zonular weakness or pseudoexfoliation - Extensive corneal scarring - High refractive error: Myopia greater than 10D, Hyperopia greater than 5D
