Posterior chamber IOL implantation with suboptimal posterior capsular support

Area of Science:

• Ophthalmology
• Surgical Techniques
• Intraocular Lenses

Background:

• Suboptimal posterior capsular support presents challenges for intraocular lens implantation.
• Rupture of the posterior capsule or zonules can compromise lens stability.
• Maintaining adequate zonular support is crucial for successful lens placement.

Purpose of the Study:

• To evaluate the efficacy of posterior chamber intraocular lens (PC/IOL) implantation in eyes with compromised posterior capsular support.
• To assess the long-term centering and stability of PC/IOLs placed in the ciliary sulcus with residual zonular support.

Main Methods:

• PC/IOLs were implanted in 24 patients with at least six clock hours of remaining peripheral zonular support.
• Haptics were placed in the ciliary sulcus, specifically over the areas of residual zonular support.
• Patient outcomes were monitored for lens centering and stability.

Main Results:

• All implanted PC/IOLs remained centered in the capsular bag.
• The mean follow-up period was 10.5 months.
• Successful sulcus fixation of haptics was achieved over the remaining zonular support.

Conclusions:

• PC/IOL implantation is a viable option for patients with significant, but not complete, loss of posterior capsular support.
• Maintaining at least six clock hours of peripheral zonular support is a key criterion for successful PC/IOL implantation and stable centering.
