Moria M2 single use microkeratome head in 100 consecutive LASIK procedures

Abstract

Purpose: To evaluate the safety and efficacy of the Moria M2 single use 130 microkeratome head in consecutive LASIK procedures for correction of myopia and myopic astigmatism.

Methods: One hundred eyes of 55 patients underwent LASIK in which the flaps were created with the Moria M2 microkeratome using the single use 130 head and excimer laser ablation was done with the Allegretto Wave-light laser. Flap parameters measured were: thickness, diameter, hinge length, and overall quality. Preoperative uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refraction, wavefront aberrations, and low contrast sensitivity were compared to postoperative values at 6-month follow-up.

Results: Mean flap thickness was 145 +/- 17.5 microm, mean flap diameter was 8.5 +/- 0.40 mm, and mean hinge cord length was 4.05 +/- 0.35 mm. At 6-month follow-up, UCVA improved from 20/200 (+/-0.24) to 20/18.5 (+/-0.12) and BSCVA improved from 20/20.5 (+/-0.18) to 20/17.5 (+/-0.11).

Conclusions: The Moria M2 single use 130 microkeratome head appears to be safe and effective in performing LASIK procedures.
