Correcting presbyopia with the laser

In order to better predict eye surgeries in the future, scientists at the LZH have developed both a mechanics as well as an optics model of the eye. Photo: LZH

For the RayFEye project, the scientists of the LZH have developed both a mechanics and an optics model.

The mechanical model was used on test eyes (a by-product of the animal) to examine how laser incisions in the lens and the cornea influence their refraction behavior.

Based on these data, the researchers then developed a biomechanical model that can also be analyzed for optical imaging performance.

The model is supposed to predict the optimal placement and the expected vision of the patient before surgery.

The long-term goal is to develop gentle surgical methods and to replace clinical studies through virtual studies.

About RayFEye

In addition to the LZH, the Optimo Medical AG (formerly Integrated Scientific Services AG), which is developing the OptimEyesTM software, and the ROWIAK GmbH, the manufacturer of the laser system, are involved in the project.

The joint project “Ray tracing in ophthalmic finite element models for predicting visual acuity enhancement” (RayFEye) was funded within the framework of the Eurostars program by the Federal Ministry of Education and Research (BMBF) and by the Swiss State Secretariat for Education, Research and Innovation (SERI) under the grant number 01QE1545B.
