Abstract Details


To study the safety efficacy and advantages of the Moria One Use-Plus SBK head.


Al Salam international Hospital, Kuwait.


500 eyes of 250 patients underwent LASIK surgery using the One Use-Plus SBK head for creation of an ultrathin LASIK flap. In follow up at 1, 6, 12 and 24 months, both uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) were recorded. A keratoconus screening corneal topography was done on the last follow up visit.


500 eyes of 250 myopic patients were included in this study, 115 males, 135 females, mean age was 27.5 years range (18 – 44). The mean preoperative refractive error was -5.0 diopters sphere, range (-3 to -9), mean cylindrical error was -2.5 diopters cylinder, range (-0.75 to -4.5). The mean UCVA was 0.07 range (0.01 -0.3), it improved to 1.0, range (0.8-1.25) on day one post operatively. At the end of the follow up, the mean UCVA was 1.0 and the mean BCVA was 1.0. The mean stromal residual bed thickness was 362µ, range (304µ to 466µ) the mean central flap thickness was 102µ, range (82 - 120). Complications were perilimbal bleeding in 15 eyes, fine irregular stromal edge cuts at the sides of the hinge in 10 eyes, no epithelial defects, no epithelial heaping or sliding, no irregular stromal bed surface cuts, no free caps or button holes or incomplete flaps, DLK occurred in one eye of one patient, no slipped flaps, macro or microstriae, or epithelial down growth were seen over the follow up period. At the end of the follow up period none of our patients had topographic evidence of keratoconus.


The One Use-Plus SBK head, is a safe and effective method for creation of an ultrathin LASIK flap, that allows the surgeon to treat higher errors of refraction while maintaining a higher safety margin by leaving more residual stromal tissue.
