Summary
A new technique uses specialized forceps for direct intraocular lens (IOL) removal, reducing risks associated with traditional methods. This minimally invasive approach offers a safer alternative for dislocated IOL extraction.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- Increasing prevalence of intraocular lens (IOL) dislocation due to lower cataract surgery age thresholds and longer lifespans.
- Conventional IOL removal techniques carry significant risks, including corneal endothelial and iris damage.
Purpose of the Study:
- To introduce and evaluate a novel, minimally invasive technique for direct IOL removal.
- To assess the safety and efficacy of specialized lens-grabbing forceps for IOL extraction.
Main Methods:
- Development of custom-designed lens-grabbing forceps for direct IOL grasping and removal.
- Implementation of a technique allowing single-motion IOL extraction through a small corneal incision (2.2 mm).
Main Results:
- Successful IOL removal in approximately 95 seconds using the new technique.
- Minimal incision enlargement (0.16 mm) and a slight, non-significant decrease in corneal endothelial cells observed.
- Reduced intraocular manipulations compared to traditional methods.
Conclusions:
- The developed technique represents a safe and minimally invasive option for dislocated IOL removal.
- This method offers a promising alternative to conventional techniques, potentially reducing surgical complications.
