Abstract Details

Purpose:

To assess the safety, reproducibility and efficacy of the Moria One Use-Plus SBK microkeratome for thin-flap LASIK similar to Femto flaps.

Setting:

Magrabi Eye Hospital, Cairo, Egypt

Methods:

It has been evaluated with single use disposable head and femtolasik flaps by the Ilasik machine. The anterior OCT Optovue - RTvue was used to assess central corneal thickness, flap thickness at apex, 3mm and 6 mm from it, the meniscus of the flap and how far from Bowman’s layer. After flap creation, the hinge width and flap diameters were measured.

Results:

With 90 disposable SBK head , the diameter of the flap was 9,44 ± 0,22 (9,10-9,80), the stromal ablation was 9,23 ± 0,23 (8,81-9,60), the hinge size was 2,19 ± 1,61 (0,00–4.99) (in mm) and the flap thickness (µ) 91,58 ± 12,58 (62-116).With Femtosecond, the diameter of the flap was 9,27 ± 0,30 (8,79-10,02), the stromal ablation was 9,10 ± 0,28 (8,31-9,79), the hinge size was 2,87 ± 2,75 (0,00-5,77) (in mm) and the flap thickness (µ)105,25 ± 15,51 (71-140).

Conclusions:

Moria One Use-Plus SBK for Thin-Flap LASIK is safe and efficiently produces smooth stromal beds and also good quality. This prospective study shows that the Moria One Use-Plus SBK microkeratome can safely, reproducible and reliable achieve SBK (Sub-Bowman's Keratomileusis) flaps as good as Femto flaps but without any Femtosecond technology.
