Abstract

Purpose: To compare the incidence of flap complications and the reproducibility of flap thickness after laser in situ keratomileusis (LASIK) surgery using three different microkeratomes: the 180 head Chiron Hansatome (Bausch & Lomb) [Hansatome], the 160 head Carriazo-Barraquer (Moria/Microtech) [Moria CB], and the 160 head SKBM (Alcon) [SKBM]. Methods: A total of 418 consecutive patients (813 eyes) underwent LASIK surgery performed by one surgeon. Following surgery, the patients were reviewed for the flap complications. A subset of 193 eyes were evaluated by measuring flap thickness via subtractive pachymetry. Results: Epithelial defect was the most common complication and occurred in 36/813 eyes (4%). The risk of epithelial defect was statistically significantly higher following LASIK using the Hansatome microkeratome (p<0.001), and when compared with the other two microkeratomes, was positively correlated with older age (p<0.002), thicker preoperative cornea (p<0.005), and diffuse lamellar keratitis (p<0.005). Flaps created using the SKBM microkeratome had the most reproducible flap thickness. Conclusion: Flap thickness predictability is important in minimizing flap-related complications. Greatest predictability of flap thickness was seen with the SKBM microkeratome, which involved the use of a second motor for advancement. Flap complications occurred infrequently with all microkeratomes. The most common complication was an epithelial defect, which occurred more frequently with the Hansatome microkeratome.
