A new technique for suture fixation of posterior chamber intraocular lenses that eliminates intraocular knots.

Abstract

The aim of this study was to describe a new technique for transscleral suturing of posterior chamber intraocular lenses (PCIOLs) without intraocular knots. Retrospective noncomparative case series. Twenty-four eyes underwent implantation of PCIOLs with this new technique. Suture fixation of PCIOLs was performed in eyes without capsular support. The anatomic and functional outcome of surgery was determined during a follow-up of 2 to 40 months. The PCIOL remained well centered without tilt in 22 of 24 (92%) eyes. The PCIOL was well centered in 16 of 17 (94%) eyes followed for > or =6 months. Complications related to lens suturing were minimal and resolved spontaneously. Final visual outcome depended almost entirely on the underlying health of the retina and optic nerve. This technique eliminates intraocular knots, minimizes operating time with an open globe, and provides excellent lens centration in the absence of capsular support.
