Summary
This study demonstrates a novel technique for removing foldable acrylic intraocular lenses (IOLs) in one piece through a small corneal incision. This method minimizes trauma, offering a safer approach for IOL extraction during eye surgery.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Biomedical Engineering
Background:
- Foldable acrylic intraocular lenses (IOLs) are commonly used in cataract surgery.
- IOL removal can be challenging, potentially leading to wound trauma and complications.
- Minimally invasive techniques are crucial for improving patient outcomes.
Purpose of the Study:
- To present a novel technique for the single-piece removal of a foldable acrylic IOL.
- To evaluate the efficacy and safety of this method in terms of wound trauma.
- To demonstrate a technique applicable through a small corneal incision.
Main Methods:
- A 6.0 mm optic foldable acrylic IOL was the subject of removal.
- Viscodissection was employed to free the IOL from the capsular bag into the anterior chamber.
- Vannas scissors were used via a 2.2 mm corneal incision to make two parallel 4.5 mm cuts at the optic-haptic junctions.
- The IOL was then removed as a single, S-configured piece.
Main Results:
- The foldable acrylic IOL was successfully removed in a single piece.
- The removal was achieved through a 2.2 mm corneal incision.
- Minimal wound trauma was observed during the procedure.
- The described cutting technique resulted in an S-shaped IOL configuration.
Conclusions:
- This technique allows for the safe and efficient removal of foldable acrylic IOLs.
- The method minimizes corneal incision size and associated trauma.
- It offers a valuable alternative for challenging IOL removal scenarios.
