Summary
A foldable intraocular lens (IOL) injector may cause Descemet's membrane tears. Preoperative microscopic inspection of surgical instruments is crucial for patient safety during cataract surgery.
Area of Science:
- Ophthalmology
- Surgical Technology
Background:
- Foldable intraocular lens (IOL) implantation via injector systems through small corneal incisions offers rapid patient recovery after cataract surgery.
- The Sensar AR40e IOL and Emerald C cartridge are commonly used for this procedure.
Observation:
- A case report details a Descemet's membrane tear with a rolled flap occurring immediately after IOL injection through a 2.8-mm clear corneal incision.
- The tear was associated with downward beaking of the injector cartridge's anterior end.
Findings:
- The injector cartridge, loaded outside the operating microscope's view, exhibited a beaked tip, indicating a potential cause for the Descemet's tear.
- This complication highlights a risk associated with the injector system during foldable IOL implantation.
Implications:
- Thorough preoperative microscopic examination of all instruments and devices is recommended to prevent intraoperative complications.
- Ensuring the integrity of the IOL injector system is vital for patient safety and successful cataract surgery outcomes.
