Filter by:The intended purpose of the investigational device in the study is the correction of myopia and myopia with astigmatism in the CE (Conformité Européene) approved range and optimized for presbyopic patients using the treatment option HiSMILE, installed on the VisuMax femtosecond laser.
A cataract is a clouding of the lens that occurs naturally with age. Cataract surgery involves removal of the cloudy lens and replacement with an artificial one. A special laser (femtosecond laser) is now being used to help make cataract surgery safer and more accurate . The femtosecond laser can also be used to correct astigmatism, an irregular curvature of the cornea, at the time of cataract surgery through a procedure called astigmatic keratotomy (AK). This study is gathering information about the specific laser settings that are used to perform astigmatic keratotomies (AK) during cataract surgery. This information will be used to improve the outcomes of patients that receive cataract surgery with astigmatic keratotomies in the future.
