A cataract is an opacity of the lens that, if left untreated, leads to impaired vision that impedes daily functioning and, as a result, often leads to complete loss of vision. The premium implants enable vision without glasses for both distance and near vision. Individual fitting of the implant, discussion of the procedure and vision according to the individual calculation will be discussed during the qualification examination. The procedure performed with a femtosecond laser increases the precision of the procedure and its anatomical accuracy. At SwissLaser, we use the ZIEMER Z8 low-energy femtosecond laser. The World Health Organization lists unoperated cataracts as the cause of 35% of all cases of reversible blindness worldwide. Until recently, only mature cataracts were operated on, but now ophthalmologists take the position that cataract surgery is advisable even in the early stages, as long as the visual impairment is severe enough to impede daily functioning.
