Verbesserung der Befestigung von Silikonschiffchenlinsen durch den Gebrauch von Positionierungslöchern in der Linsenhaptik

Silicone plate haptic IOLs seem to present special risks for dislocation. Shrinkage of the anterior capsule exerts centripetal forces on the ends of the plate haptic, causing the optic to move posteriorly and to exert pressure against the posterior capsule. If either the posterior or anterior capsule is disrupted by Nd:YAG laser treatment, the forces created by capsular contraction against the flexible lens may cause extension of radial tears and appear to be a substantial risk for further capsule-tearing, releasing the IOL into the vitreous cavity, even months later. The forces of capsular contraction can impart a spring-loading effect on plate haptic silicone lenses. Due to inadequate capsular adherence, these lenses are at risk of posterior dislocation from capsular rents following Nd:YAG laser treatment.
