Abstract
Clinical Evidence of Ambient Temperature Variations on Femtosecond Laser Performance and Comparison with a Mechanical Microkeratome
Highlights
The mechanism of flap creation with the IntraLase femtosecond laser has already been described extensively in the literature [1,2,3,4,5] over the years
Corneal flaps created from 60 kHz femtosecond laser (IntraLase FS Laser, AMO, Abbott Park, Ill, USA) were compared to those created from a mechanical microkeratome (Amadeus II, Ziemer Group, Port, Switzerland)
In the femtosecond laser group, 94% (292 eyes) of all treated eyes were within ± 0.5D of the intended manifest spherical equivalent refraction at the first month, improving to 95% (295 eyes) at the third month and 97% (302 eyes) at the sixth month
Summary
The mechanism of flap creation with the IntraLase femtosecond laser has already been described extensively in the literature [1,2,3,4,5] over the years. The ultra-short impulses are focused at a spot size of a few micrometers in diameter at a preset depth within the stroma, leading to photo disruption and to a creation of a corneal resection plane. Several studies showed an improved flap predictability and refractive outcomes compared with that of the mechanical microkeratome [6,7,8]. The use of this technology helped to reduce or eliminate many of the minor or even severe complications associated with the flap creation [2,4,6,7,8,9]
