Purpose:
The aim of this study was to describe a new technique for transscleral suturing of posterior chamber intraocular lenses (PCIOLs) without intraocular knots.
Design:
Retrospective noncomparative case series.
Participants:
Twenty-four eyes underwent implantation of PCIOLs with this new technique.
Methods:
Suture fixation of PCIOLs was performed in eyes without capsular support.
Main Outcome Measures:
The anatomic and functional outcome of surgery was determined during a follow-up of 2 to 40 months.
Results:
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.
Conclusion:
This technique eliminates intraocular knots, minimizes operating time with an open globe, and provides excellent lens centration in the absence of capsular support.
