PURPOSE: The Zepto nano-pulse precision capsulotomy is a novel device for capsulorhexis formation during cataract surgery. Few complications or challenges have been reported while using this device. The purpose of this paper is to highlight two intra-operative challenges that were encountered while using the Zepto device.
OBSERVATIONS: CASE 1 - A 65-year-old with advanced primary open angle glaucoma (POAG) and an in situ Ahmed Glaucoma Valve located in the anterior chamber. During a planned phacoemulsification procedure, the tube became trapped between the suction cup of the Zepto device and the lens, resulting in a sudden complete collapse of the anterior chamber. The procedure was completed after appropriate interventions. On post-operative day 1 Descemet folds were visible, and corneal endothelial cell density was reduced from 2101 cells/cm2 preoperatively to 1355 cells/cm2 at 19 months postoperatively. CASE 2 - A 66-year-old female with secondary cataract from chronic inflammation post trabeculectomy for advanced POAG. During a planned phacoemulsification procedure, despite synechialysis for the 360° posterior synechiae, the iris tissue was sucked into the suction cup of the Zepto device and became incarcerated over the lens. The procedure was completed after a successful intervention.
CONCLUSIONS AND IMPORTANCE: Although not previously reported and possibly rare, intra-operative complications may be encountered while using the Zepto device, particularly in complex cataract cases. For the patient's safety and satisfactory post-operative and refractive outcomes, caution must be applied.
