Summary
The Zepto device for cataract surgery can cause rare intra-operative challenges, especially in complex cases with glaucoma or inflammation. Surgeons should exercise caution during Zepto-assisted capsulorhexis to ensure patient safety and optimal outcomes.
Area of Science:
- Ophthalmology
- Surgical Technology
- Medical Devices
Background:
- The Zepto nano-pulse precision capsulotomy is a novel device for creating the capsulorhexis during cataract surgery.
- While generally safe, potential intra-operative challenges with this device are not widely reported.
Observation:
- Case 1 involved a 65-year-old with advanced primary open angle glaucoma (POAG) and an Ahmed Glaucoma Valve, where the valve tube became trapped by the Zepto device, causing anterior chamber collapse and reduced endothelial cell density.
- Case 2 involved a 66-year-old with secondary cataract post-trabeculectomy, where iris tissue was incarcerated into the Zepto device's suction cup despite synechialysis.
Findings:
- These cases highlight two distinct intra-operative complications encountered during Zepto-assisted capsulorhexis in complex cataract surgeries.
- Complications included anterior chamber collapse due to trapped glaucoma device tubing and iris incarceration within the device.
Implications:
- Intra-operative complications, though possibly rare, can occur with the Zepto device, particularly in patients with pre-existing ocular conditions like glaucoma or chronic inflammation.
- Careful patient selection and surgical technique are crucial for mitigating risks and ensuring favorable outcomes in Zepto-assisted cataract surgery.
