Paper Abstract

In ophthalmology, femtosecond laser transections (photodisruption) in the vicinity of the retina need to be performed with minimized threshold energy to not harm peripheral retinal tissue. However, the aberrations of the anterior eye elements cause a distortion of the wavefront and therefore a raised threshold energy when focussing into the posterior segment. We present an optical system that allows for correcting aberrations in eyes using adaptive optics consisting of a deformable mirror and a Hartmann-Shack-Sensor with a novel light source. If combined with femtosecond laser pulses this system offers the possibility for minimally invasive laser surgery in the posterior eye segment.
