Abstract

Purpose: To compare the incidence of intraoperative corneal abrasions using the Hansatome® (Bausch & Lomb Surgical) and Amadeus (Advanced Medical Optics) microkeratomes and to determine whether there is a correlation between patient age and the occurrence of intraoperative corneal abrasions. Setting: Outpatient ambulatory laser vision correction center. Methods: The charts of 133 patients (263 eyes) having laser in situ keratomileusis (LASIK) were reviewed retrospectively. The patients were randomized to LASIK performed by 2 surgeons using the same technique with alternative microkeratome selection. Results: The incidence of intraoperative corneal abrasions was significantly higher with the Hansatome microkeratome than with the Amadeus microkeratome (P = .014). There was a significant correlation between increasing patient age and the incidence of corneal abrasions with both microkeratomes (P<.05). Conclusions: Laser in situ keratomileusis surgeons should be aware that certain microkeratome designs pose a higher risk for intraoperative corneal abrasions and that older patients are more susceptible to intraoperative corneal epithelial injury. These patients should be informed accordingly for appropriate consent.
