Abstract

Abstract: : Purpose: To investigate the wound temperature gradient and safety of using White Star micropulse technology phacoemulsification without an irrigation sleeve. Methods: 10 patients underwent phacoemulsification using White Star micropulse technology without an irrigation sleeve through a 1.2 mm clear corneal incision. A thermocouple was inserted into the cornea directly adjacent to the wound to digitally record temperature gradients at the wound. Corneal clarity and endothelial cell counts were evaluated pre-operatively and post-operatively. Results: All 10 patients maintained corneal clarity without sign of thermal damage to the wound. Corneal wound temperatures ranged from 19 to 34 degrees Celsius. Conclusion: White Star micropulse technology phacoemulsification maintains corneal wound temperatures significantly below the temperature of collagen shrinkage. Therefore, this type of phacoemulsification can safely be performed through a 1.2 mm incision without an irrigation sleeve.
