Methods20 cadaver corneas, underwent LASIK flap creation Group A(10 corneas)with the Wavelight, Ultraflap 150kHz and Group B (10 corneas) with the INTRALASE FS60Peri-operatively the flap diameter (FD), hinge length (HL) , total cornea and flap pachymetry(tP & fP), and flap creation interval were measured. Following tissue fixation, light microscopy sections were calculated for: peripheral, para-central and central thickness, intra-flap thickness variability (IFTV), diameter, hinge length and overall interface quality.

Results

Group A: In mean values: fP: 110 microns +/- 5μm, IFTV: (+/- 5)μm. FD: 8.2 mm, HL: 3.55 mm +/- 0.34, creation time 15 secondsGroup B: In mean values: fP: 115 +/-5μm(intended: 110), IFTV: (+/-5)μm, FD: 8.1 mm(intended: 8), HL: 3.25mm +/-0.24, creation time 17 seconds

Conclusions

• This study suggests highly reproducible flap parameters with both platforms. Further clinical studies may validate these data.
