Kombination verschiedener Techniken bei sekundärer Verankerung intraokularer Linsen

Abstract

The four fundamental techniques of secondary intraocular lens (IOL) fixation, namely sulcus placement, scleral or iris suture fixation and scleral haptic fixation can be combined in special situations. When is a combination of different techniques advisable? This article describes our experiences and gives an example of combined technique use. These situations arise in cases when neighboring ocular structures are only partially preserved or show particular distinctive defects that can be repaired at the time of secondary IOL anchoring. This article presents a case of IOL-induced iris chafing and traumatic iridodialysis which was closed by a combined technique of iris suture and scleral suture fixation. A combination of different anchoring techniques for secondary IOL implantation can achieve a simultaneous repair of perilenticular structures and reduce the amount of suture material used.
