Laboratory evaluation of LASIK flap parameters created with 2 femtosecond lasers ASCRS, San Diego 2011 Chatzilaou, Georgios, MD¹ A.

Kanellopoulos, MD www.brilliantvision.com Purpose The laboratory evaluation of LASIK flap of a novel femtosecond laser versus our standard. FS60 FS 200 Kanellopoulos, MD www.brilliantvision.com

Kanellopoulos, MD www.brilliantvision.com Methods 20 cadaver corneas, underwent LASIK flap creation Group A(10 corneas)with the Wavelight, Ultraflap 150kHz and Group B (10 corneas) with the INTRALASE FS60 Peri-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. Kanellopoulos, MD www.brilliantvision.com

Comparison of simultaneous use Kanellopoulos, MD www.brilliantvision.com

Kanellopoulos, MD www.brilliantvision.com 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 seconds Group 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 Kanellopoulos, MD www.brilliantvision.com

Kanellopoulos, MD www.brilliantvision.com Conclusions This study suggests highly reproducible flap parameters with both platforms. Further clinical studies may validate these data. Kanellopoulos, MD www.brilliantvision.com
