Clinical Trial Summary

The investigational device is an approved femtosecond laser (FSL) device with an integrated imaging system to perform certain steps of the cataract procedure including arcuate incisions (AI) correcting astigmatism, also referred to as arcuate keratotomy (AK). The FSL will perform anterior capsulotomy and lens fragmentation in individuals suffering from age-related cataract with need of cataract surgery and additionally perform arcuate keratotomy in individuals with more than 1.0 Diopter (dpt) of astigmatism. Cataract surgery will be performed in subjects who have signed an informed consent form. Postoperative examinations will be implemented in accordance with the approved Investigational Plan on subjects and includes: postoperative refraction, visual acuity, slitlamp examination, and corneal topography
