Dislocation of Binkhorst four-loop lens implant.

Area of Science:

• Ophthalmology
• Surgical Innovation
• Medical Device Technology

Background:

• Intracapsular cataract extraction (ICCE) involves risks of intraocular lens (IOL) dislocation.
• Binkhorst four-loop lenses are a type of IOL used in ICCE.
• Suture fixation techniques aim to improve IOL stability post-surgery.

Purpose of the Study:

• To evaluate the effectiveness of different suture fixation methods for Binkhorst four-loop implants in ICCE.
• To determine the optimal technique for minimizing IOL dislocation.
• To assess the safety and efficacy of suture fixation in preventing complications.

Main Methods:

• Analysis of 1,093 consecutive Binkhorst four-loop lens implantations.
• Comparison of three groups: transiridectomy suture fixation (497 cases), no suture (403 cases), and simple iris suture (193 cases).
• Evaluation of implant dislocation rates and procedural safety.

Main Results:

• The transiridectomy suture fixation group exhibited the lowest rate of implant dislocation.
• The simple iris suture technique demonstrated a favorable safety profile.
• No suture fixation was associated with a higher risk of dislocation compared to fixation methods.

Conclusions:

• Suture fixation is crucial for Binkhorst four-loop implants in ICCE to mitigate dislocation risks.
• The simple iris suture technique is recommended due to its safety, balancing stability and risk.
• Further research may explore modifications to enhance fixation security while maintaining safety.
