[Comparison of the diameter and thickness of the corneal lamella in LASIK surgery using the oscillating microkeratome].
Corneal lamellas created by two different microkeratomes--oscillating and rotating are compared. Oscillating microkeratome Flapmaker (Refractive Technologies) and rotating Dreager microkeratome (Storz) were used for tis study. Diameter and thickness of the lamella were assessed. Rabbit lamella created by the same procedure as human differs significantly and this limits the interpretation of rabbit experiments to the human eyes. Oscillating microkeratome Flapmaker created more precise and standard lamella (standard deviation 4 times smaller) compared to rotating Storz on human eyes. Differences in lamella thickness in different topografical areas of the lamella were 3.3 times smaller with Flapmaker. We conclude that desired mean lamella thickness homogenity in different topografical areas of the lamella are much better with Flapmaker compared to Dreager microkeratome on human eyes.
