Sometimes months or years after a cataract operation, a slow deterioration in vision may occur again- a posterior capsule opacification (PCO, secondary cataract) has formed. This is caused by epithelial lens cells remaining in the capsular bag during surgery. They slowly grow towards the posterior capsule in the direction of the visual axis and form an increasingly dens cell layer. As a result, the vision becomes blurry and cloudy again.
In the development of modern intraocular lenses, the prevention of posterior capsule opacification plays a major role. The material and design of intraocular lenses are constantly developed and improved. Posterior capsule opacification has been one of my main research areas for years; in the course of this I have carried out many clinical studies with my study group and published our results. I am happy to let my patients benefit from this knowledge and my experience.
Posterior capsule opacification laser treatment
Posterior capsule opacification is treated with a laser (Nd:YAG laser capsulotomy). The posterior capsule is opened by the laser so that the visual axis is free again and vision is clear again. The posterior capsule laser can be performed in our private practice. The treatment is completely painless and usually only takes a few minutes. A secondary cataract cannot come back—once the posterior capsule is removed, the cells can no longer grow.
