Thus, after the operation, either the patient's vision would be impaired, or the accommodation of the lens would be limited. In the "Lens-Refilling" project, LZH scientists and the LZH spin-off ROWIAK GmbH want to develop a new approach. The idea is to precisely remove only the nucleus of the eye lens and replace it with lens refilling. To this end, they are developing and evaluating a method with which they can technically implement lens nucleus fragmentation while fully preserving the physiological structures.
The lens cortex would remain untouched with this new method of nuclear fragmentation using femtosecond lasers. This would likely prevent the complications mentioned above. Thus, it would be possible to restore accommodative ability after lens refilling.
This method could be used for age-related lens opacities, such as cataracts, or to compensate for presbyopia. Currently, the damaged lens is usually removed and replaced with an artificial one. However, this artificial lens cannot accommodate itself, and the patient loses the ability to see sharply at any distance. The new method would help reduce the risk of postoperative cataracts. Patients should be able to go for a longer time without having to undergo another operation.
