Abstract Details

Purpose:

To evaluate the efficacy, safety, predictability, ocular aberrations, and flap thickness predictability of VisuMax femtosecond laser compared to Moria M2 microkeratome in mild to moderate myopia.

Setting:

Ophthalmology Department, Dar AlSifa hospital, Kuwait.

Methods:

This study involved 60 eyes of 30 patients who were divided into two groups. Group (I) included 30 eyes in which the flap was created with VisuMax femtosecond laser, while group (II) included 30 eyes in which the Moria M2 microkeratome was used. Refractive, keratometric, and aberrometric measurements were compared preoperatively and 3 months postoperatively. Flap thickness was measured using the intraoperative subtraction pachymetry.

Results:

No significant difference was found between the two groups in regards to postoperative manifest sphere, astigmatism, SE, safety indices nor ocular aberrations. 26 eyes (86.6%) in group I and 23 eyes in group II (76.6%) were within + 0.5D of the intended correction and 23 eyes (76.6%) in group I and 15 eyes in group II (50%) were within + 0.25D of the intended correction. In group I, the mean postoperative actual flap thickness was 100.12 + 16.1µm (81 to 122 µm), while in group II, it was 104.6 + 20.1µm (62 to 155 µm)(p= 0.001).

Conclusions:

Both VisuMax and Moria M2 microkeratome are safe and effective in treating myopia with no statistically significant difference in induction of ocular aberrations but with potential advantage for VisuMax regarding predictability. More accurate flap thickness is achieved with Visumax femtolasik. FINANCIAL DISCLOUSRE: NONE
