Intraocular lens technology is in a process of permanent development, due to the increasing visual needs of patients undergoing cataract surgery. That is why we set out to do a search about the different lens models of lenses are offered, including the monofocal, bifocal, trifocal, toric trifocal and extended focus types. This new technology requires rigorous and accurate preoperative tests, so that surgical results respond to the concept of refractive crystalline lens surgery. We therefore conclude that future intraocular lens technology should be aimed at recovering functional vision. Each of the lens types has its own strengths and weaknesses, and so a universal solution does not exist. A report should be developed of advantages and disadvantages, so that work can be done on aspects requiring improvement, mainly the standardization of the improper focusing curve, the modulation transfer function and contrast sensitivity, as well as the implementation of actions to be performed jointly by patients, surgeons and manufacturers.

Palabras clave : Cataract; monofocal intraocular lens; bifocal; trifocal; toric trifocal; extended focus.
