Modern Directions of Intraocular Lenses Improvement. Literature Review

Today, cataract surgery is almost always accompanied with aphakia correction by implantation of an intraocular lens (IOL). In addition to the constant improvement of surgical techniques, special IOLs with improved characteristics are being developed, allowing any optical task to be solved with a minimum of side effects.

Optimization of the material, shape and optical design of IOLs remain.
