Summary
A new lens bisector tool safely cuts silicone intraocular lenses (IOLs) in half within the eye. This allows for atraumatic removal through a small incision, enabling new lens insertion.
Area of Science:
- Ophthalmology
- Surgical Instrumentation
Background:
- Silicone intraocular lenses (IOLs) can be challenging to remove through small incisions.
- Existing methods for IOL removal may require larger incisions or specialized techniques.
Purpose of the Study:
- To introduce and describe a novel surgical device, the lens bisector, for fragmenting silicone IOLs.
- To evaluate the efficacy of the lens bisector for atraumatic IOL extraction via a 3.0 mm incision.
Main Methods:
- The lens bisector utilizes a disposable wire sling within a metal tube.
- The device is used by positioning the IOL in the anterior chamber, placing the sling over its center, and retracting it into the tube to bisect the lens.
- Extracted IOL halves are removed, and a new IOL can be inserted.
Main Results:
- The lens bisector effectively bisects silicone IOLs.
- The procedure allows for atraumatic removal of IOL fragments.
- Extraction and subsequent new IOL insertion are feasible through a 3.0 mm incision.
Conclusions:
- The lens bisector is a novel and effective tool for managing difficult-to-remove silicone IOLs.
- This device facilitates minimally invasive IOL exchange procedures.
