Objective:
To investigate the results and technology of making corneal flaps with Moria M(2) microkeratome.
Methods:
Eight hundred and six corneal flaps (in 409 cases) were made using Moria M(2) microkeratome in LASIK. The group consisted of 205 males (405 eyes), whose mean age was (23.61 +/- 5.44) years, mean refractive spherical equivalent was (-6.32 +/- 3.61) D, and mean corneal thickness was (542.72 +/- 29.54) micro m. The 130-micron head option was chosen, the pressure was less than 250 mm Hg (1 mm Hg = 0.133 kPa), the stop-ring was adjusted to the 8.0 mm position and the suction ring was chosen according to corneal curvatures.
Results:
All 806 corneal flaps were made successfully at one time with suitable hinge size, and without ruptured or thin or incomplete flaps. Flaps could be turned and reattached easily. There was no breaking down during the surgical procedure. The flaps showed smooth edges with smooth keratectomy beds.
Complications:
(1) Free flaps occurred in 3 eyes (0.37%). (2) Island phenomenon occurred in 2 eyes (0.25%). (3) Failure to make the flaps occurred in 3 eyes (0.37%).
Conclusion:
All 806 corneal flaps were made successfully at one time with no serious complications. Choosing the suction ring according to corneal curvature, checking blades preoperatively and inserting blades correctly may help to avoid complications when making corneal flaps with Moria M(2) microkeratome.
