Abstract Details

Purpose:

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.

Setting:

Magrabi Eye Hospital,Cairo,Egypt.

Methods:

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.

Results:

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).

Conclusions:

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
