to clear vision
Recognising the first signs
Blurred vision, sensitivity to glare or frequent changes in your glasses prescription can be early signs. An ophthalmologist confirms the diagnosis with a slit-lamp examination in a few minutes.
Learn morePreliminary examination and personal consultation
Before the operation, the eye is measured precisely (biometry) to calculate the best artificial lens. In the informed-consent consultation, you and the surgeon decide together which lens suits your daily life.
Learn moreSurgery
The clouded lens is broken up by ultrasound (phacoemulsification) and removed, then the new artificial lens is inserted. No general anaesthesia, no incision that needs stitches. You go home the same day.
Learn moreAftercare & result
In the first weeks, eye drops protect against inflammation. Follow-up appointments take place the next day, after one week and after four weeks. Only then are new glasses fitted. Many patients no longer need any.
