[Evaluation of the cut quality of the Masyk microkeratome in obtaining corneal flap from porcine eyes].
OBJECTIVE
Evaluation of the cut quality of the Masyk microkeratome in obtaining corneal flap from porcine eyes.


METHODS
Prospective study with 31 porcine eyes divided into two groups: 15 eyes with programmed flap thickness of 160 microm and 9.5 mm diameter (Group 1), and 16 eyes with programmed flap thickness of 140 microm and 8.5 mm diameter (Group 2). Corneal thickness was calculated with a P55 pachymeter (Paradigm, USA) and the diameter with compass.


RESULTS
No complications were observed during the use of the microkeratome. In group 1, the central corneal thickness mean was 146.33 +/- 15.43 microm, range between 127 and 186 microm, and the vertical diameter mean was 9.39 +/- 0.26 mm, range from 8.90 to 9.85 mm. In group 2, the central corneal thickness mean was 128.75 +/- 18.83 microm, range from 71 to 178 microm, and the vertical diameter mean was 8.27 +/- 0.20 mm, range from 7.95 to 8.65 mm.


CONCLUSIONS
The Masyk microkeratome showed to be effective and safe to produce corneal flaps with appropriate thickness and diameter in porcine eyes.
