Toward optical correction of cataract opacities

Abstract

Cataracts is a common pathology where the crystalline lens tends to become opaque, degrading the quality of the retinal images because of the increase of scattering. This leads to a deterioration of visual quality affecting the life of patients. The widely used solution is cataract surgery, replacing the natural lens with artificial intraocular lenses. Although surgical approaches are very successful, it would be useful to have alternative non‐invasive approaches based in optics to correct the retinal images in cataract patients. There are different options, some of them already tested in my laboratory. In this presentation, I will describe some of those based in wavefront shaping technologies. Results in simulations and using excised crystalline lenses will be shown and the prospects and limitations for practical in vivo implementations will be discussed.
