Abstract

Purpose: : To determine the percentage of wound burns associated with various phaco machines and incision sizes in the U.S. and Canada.

Methods: : Web-based survey of practices across the U.S. and Canada. Data analyzed included the number of incision wound burns, presence of ophthalmic viscosurgical devices (OVDs), phaco system employed, cataract removal technique, phaco system settings, and tip occlusion.

Results: : There were a total of 957,323 phaco procedures and 415 wound burns reported (0.04%). 157 (38%) burns were associated with continuous, 140 (34%) with OZiL, 51 (12%) with pulse, 44 (11%) with hyperpulse, 4 (1%) with burst and 0 with Ellips ultrasound. For each system, the incidence was 0% for Ellips for about 12116 surgeries vs OZil incidence of 0.030% (172,723 surgeries) and 0.072% for OZil + longitudinal (173,460 surgeries). Of the wound burns, 211 occurred with incisions between 2.41-2.79mm, 132 occurred with incisions ≥ 2.8 mm. 244 (59%) of burns occurred with OVD present in the anterior chamber.

Conclusions: : Although wound burn is uncommon in modern cataract surgery, the type of machine used, power modality, incision size and presence of OVD are related to this problem.
