Abstract

PURPOSE
To compare intraoperative and postoperative flap complication rate between the Hansatome Excellus and Zyoptix XP microkeratomes for LASIK surgery. METHODS: The intra- and post-operative flap complication rate, in 323 eyes of 167 patients operated on using the Hansatome microkeratome were compared with 260 eyes of 132 patients that were operated on using the Zyoptix XP microkeratome.
RESULTS
The Hansatome group showed an intraoperative complication incidence of 2.7% compared to 0.4% for the Zyoptix XP group (p<0.05), but the incidence of postoperative complication was 2.7% in the Zyoptix XP group compared to 0.6% in the Hansatome group (p>0.05). There was no incidence of visually significant complications in either group.
CONCLUSIONS
The Zyoptix XP showed a significantly decreased intraoperative flap complication rate compared to the Hansatome Excellus microkeratome. The preoperative K value is an important factor for safe LASIK.
