Comparative Study of Stromal Bed Quality by Using Mechanical, IntraLase Femtosecond Laser 15- and 30-kHz Microkeratomes

Abstract

The IntraLase 15-kHz femtosecond laser 110-microm flaps and the Hansatome 160-microm head using a new blade both produced smooth, good-quality, compact stromal beds as assessed qualitatively by masked observers and quantitatively by image analysis software. The 30-kHz femotsecond laser permits a tighter spot/line separation and lower energy per pulse, which creates smoother corneal stromal beds.
