We currently have intraocular lenses with flexible materials, which allow them to be inserted through the small incision made at the beginning of surgery. There are different types of lenses, from monofocal, such as the glass of glasses to see far and multifocal lenses, to see far and near. In recent years, a new type of lens has appeared that tries to emulate the physiological mechanism of the lens, these are progressive trifocal lenses, which offer better optical quality and the possibility of eliminating dependence on glasses, both for distance, intermediate vision, as close. We have the qualitative leap in cataract surgery in a future that is already a reality for some centers like ours. It involves implanting intraocular lenses with the ability to be "molded" 2 weeks after surgery. It consists of a material that is sensitive to ultraviolet light, which allows correcting the small graduation defects that may remain after surgery, eliminating optical aberrations to improve visual quality and incorporating the correction of astigmatisms or multi-focal profiles, according to the needs of each person. . In this way, we can speak of a truly personalized surgery for each patient, ensuring maximum vision potential in a safe and very effective way. These results will last a lifetime, without the need for further adjustments or the need to wear glasses.
