Purpose:
To assess safety, efficacy and flap performance of One Use-Plus SBK microkeratome (Moria SA, France) to perform Sub Bowman’s Keratomileusis (SBK) for intended 100-micron planar flaps using 2 types of suction rings.
Setting:
: Eye Care Hospital, Sao Paulo, Brazil
Methods:
First 500 eyes of 250 ametropic patients have been included for thin-flap LASIK surgery using One Use-Plus SBK microkeratome.
Metallic (reusable) suction rings were used in 440 eyes of 220 patients, and single-use plastic rings were used in remaining 60 eyes of 30 patients. Choice of rings and stop positions were based on nomograms provided by the manufacturer.
Speed 2 (fast speed) was routinely selected on the Evolution 3E console unit (Moria) for every case.
Flap profile and thickness have been estimated using anterior segment OCT (Visante, Zeiss) in vertical and horizontal meridian at 1 week postop.
Flap complications have been reported.
Results:
Mean flap thickness was 102.4 ± 6.8 microns, ranging from 81 to 128 microns.
Flap dimensions were always properly sized to allow consecutive excimer treatment: no laser treatment has been cancelled nor delayed, and no intraoperative flap complication has been experimented.
Metallic rings create approximately 0.5mm larger flaps than plastic rings.
Flap architecture was consistent in shape with a planar profile in both vertical and horizontal meridian: less than 5-micron difference was found between flap thickness in center and periphery.
No complaint of DLK nor postoperative flap complication has been reported, probably due to disposable heads used for every case.
Conclusions:
Moria One Use-Plus SBK microkeratome is a safe and accurate automated microkeratome for the creation of 100-micron planar flaps. It allows refractive surgeons to provide high level of safety surgeries for patients with a unique fully single-use solution.
