Outcomes of Using Sutureless, Scleral-Fixated Posterior Chamber Intraocular Lenses

Area of Science:

• Ophthalmology
• Surgical Innovation
• Intraocular Lens Implantation

Background:

• Sutureless, scleral-fixated posterior chamber intraocular lens (SSFIOL) implantation offers a solution for patients lacking adequate capsular support during cataract surgery.
• This technique is a viable alternative when standard cataract surgery is not feasible due to compromised capsular integrity.

Purpose of the Study:

• To evaluate the indications for SSFIOL implantation.
• To assess the visual outcomes and refractive results following SSFIOL implantation.
• To identify and analyze the complications associated with SSFIOL implantation.

Main Methods:

• A retrospective, investigational cohort study was conducted on 112 consecutive SSFIOL implantations.
• Data collected included pre-operative ocular conditions, surgical indications, and post-operative outcomes.
• Visual and refractive results were compared between pre-operative and latest post-operative visits.

Main Results:

• The primary indication for surgery was dislocated intraocular lens (IOL) due to zonular weakness (68.8%).
• Significant improvements were observed in uncorrected visual acuity (logMAR 1.3 to 0.64) and best-corrected visual acuity (logMAR 0.6 to 0.36).
• Common complications included transient IOP elevation (26.8%), cystoid macular edema (14.3%), and uveitis-glaucoma-hyphema (UGH) syndrome (11.6%).

Conclusions:

• SSFIOL implantation is a reasonable surgical option for eyes with inadequate capsular support, leading to visual enhancement in the majority of patients.
• Complications, particularly those involving the iris-lens diaphragm, were noted and may be linked to complex ocular pathologies.
• Surgical technique modifications can potentially mitigate iris-related complications.
