Long-Term Analysis of IOL Stability of the Lewis Technique for Scleral Fixation

Abstract

The Lewis technique for IOL scleral fixation is an optimal surgical technique in case of absence of capsular support. No IOL luxation in the vitreous chamber has been reported; only 2 of the 10 patients with at least one eroded knot presented a minimal decentration of the lens with no influence on visual acuity. Although knot erosion is not an uncommon occurrence, IOL remains stable in the long term, probably due to a fibrotic process around the suture, and the IOL haptics, which prevent IOL dislocation.
