Summary
This study introduces a novel lens glide technique to safely manage interior zonular ruptures during cataract surgery. The method facilitates cortical cleanup and intraocular lens insertion, preventing complications in 12 cases.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Cataract Surgery
Background:
- Manual extracapsular cataract extraction (ECCE) can be complicated by interior zonular rupture.
- Managing zonular defects during ECCE requires specialized techniques to ensure safe intraocular lens (IOL) implantation.
Purpose of the Study:
- To describe and evaluate a new technique using a lens glide for safely concluding ECCE with interior zonular rupture.
- To assess the efficacy and safety of the lens glide technique in preventing complications.
Main Methods:
- A novel lens glide is inserted into the anterior chamber and positioned in the capsular bag.
- The glide is sutured to the sclera to stabilize it during the procedure.
- The technique allows for aspiration of retained cortical material and in-the-bag IOL implantation.
Main Results:
- The technique was successfully applied in 12 eyes with pseudoexfoliation and zonular rupture.
- No intraoperative complications, such as vitreous loss or lens displacement, were observed.
- No postoperative complications were reported in the treated eyes.
Conclusions:
- The described lens glide technique provides a safe and effective method for managing interior zonular ruptures during ECCE.
- This approach facilitates uncomplicated in-the-bag IOL implantation even with significant zonular compromise.
- The technique shows promise for improving outcomes in complex cataract surgeries.
