Abstract Details


To assess the safety, reproducibility and efficacy of flaps done by mechanical microkeratomes ( Moria One use Plus SBK microkeratome and Moria M2)and Femtolasik flaps and comparing their results.


Magrabi Eye Hospital,Cairo,Egypt.


It has been evaluated for mechanical microkeratome (One Use Plus SBK and Moria M 2 ) and Femtolasik flaps.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.


With 90 head the diameter of the flap was 9,38 ± 0,32 (8,80-10,00), the stromal ablation was 9,07 ± 0,29 (8,30-9,80), the hinge size was 2,89 ± 2,74 (0,00-5,80) (in mm) and the flap thickness (µ)105,27 ± 15,46 (70-141); With 90 head New Blades and with metallic ring the diameter of the flap was 9,45 ± 0,21 (9,10-9,80), the stromal ablation was 9,23 ± 0,22 (8,80-9,60), the hinge size was 2,18 ± 1,61 (0,00–5,00) (in mm) and the flap thickness (µ) 91,59 ± 12,58 (63-115).


Although Femto flaps are efficient, Moria One Use-Plus SBK for Thin-Flap LASIK is safe and efficiently produces thin flap with smooth stromal beds, big flep and also good quality compared to Moria M 2. 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 i.e Cheaper technique unlike Morai M 2
