Corneal lamellas created by two different microkeratomes – oscillating and rotating are compared. Oscillating microkeratome Flapmaker (Refractive Tech- nologies) and rotating Dreager microkeratome (Storz) were used for this study. Diameter and thickness of the lamella were assessed. Rabbit lamella created by the same procedure as human differs significantly and this limits the interpreta- tion of rabbit experiments to the human eyes. Oscillating microkeratome Flapma- ker created more precise and standard lamella (standard deviation 4 times smaller) compared to rotating Storz on human eyes. Differences in lamella thic- kness 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.
