AIM: To evnh line actual versus expected laser in situ keratomileusis (LASIK) flap thickness using the Mona M2.130 microlceratome head. METHODS: 50 eyes of 25 patients scheduled for LASIK surgery for myopia where enrolled in this study. Patients were prepared for surgery. On the d n j of surgery they were admitted to the LASIK room where the lids were sterilized and draped. A suction lid speculum was applied to one eye after instilling one drop of Benox into the conjunctival sac, the eye was then washed with balanced salt solution BSS and the suction of the lid speculum activated to assure there was no excess BSS in the conjunctival sac then affital preoperative ultrasonic central corneal pachymetry reading using the sterile probe of the Tomey AL-2000 pachymer was recorded. The suction ring of the Mona M2 mikrolcetatome was centered on the cornea and immediately after the lasik flap was fashioned and the suction ring removed the flap was elevated then an intra operative central stromal bed pachmetry reading was recorded using the sterile Tomey AL- 2000 pachymer probe. The actual }lap thickness was calculated by subtractirug the intra operative central strornal thiclmess from the preoperative central corned thickness.
