Interface quality of endothelial keratoplasty buttons obtained with optimised femtosecond laser settings.

Aim: To optimise interfaces of endothelial buttons created with femtosecond (FS) lasers.

Setting: Department of Ophthalmology, Hôtel-Dieu Hospital, Paris, France.

Methods: Forty-two corneas were divided into five groups of various cutting patterns and a control group of 100 μm laser in situ keratomileusis flap creation.
