Problems solved by technology
Additionally, hydrophobic lens materials are typically more viscous, which can lead to complications during the deployment process, as the stickiness may prevent the lens from deploying or the haptic feedback partly stick to the optic
Many known hydrophobic lens materials are made into harder materials to reduce sparkle and reduce stickiness, but harder lens materials also unfold more slowly, which affects the efficiency of the process, are more difficult to inject, and even May cause nozzle rupture during surgery

Abstract
The invention pertains to intraocular lens compositions comprising a polymeric mixture of monomers, a product comprising such compositions and uses thereof. The compositions of the inventions are completely vacuole-free, therefore resulting in a truly glistening free material. Moreover, they are soft enough to be easy to fold, have a properly tuned hardness to provide comfortable unfolding speed, require a low injection force, do not present prohibitive tackiness, and have good optical properties. Finally, the present intraocular lens compositions do not suffer from calcification.
Description
Background technique [0001] The present invention relates to the field of intraocular lens compositions. [0002] An intraocular lens is a lens (len) that can be implanted in the eye to replace or assist the natural lens material in providing visual function. In the case of, for example, cataract treatment or myopia treatment, an intraocular lens may be implanted in the eye. [0003] Cataracts affect the natural lens of the eye, causing it to become cloudy, which can blur vision. In this case, the natural lens can be replaced with an artificial lens, thereby restoring vision. Other conditions, such as nearsightedness, can be treated by placing an artificial lens over the natural lens, which alters the optical power of the eye. [0004] Intraocular lens materials are known and many varieties exist commercially or experimentally. Typically, intraocular lens materials are polymeric compositions of one or more monomers. Important features of this material are clarity and stab...
