Purpose: To describe the evaluation of 2 new intraocular lenses (IOLs) manufactured with newly developed materials with special properties.
Materials and Methods: Experimental studies with human eyes obtained postmortem, animal models (rabbit and cat), as well as in vitro studies were used to evaluate 2 new IOLs: the Light Adjustable Lens (LAL), and the photochromic lens.
Results: The LAL can have its dioptric power adjusted postoperatively, upon light irradiation, in a non-invasive manner. The photochromic lens turns yellow upon exposure to ultraviolet light, otherwise, it remains colorless, eliminating eventual problems with decreased scotopic vision with yellow lenses.
Conclusion: The newly developed materials described here have the potential to further influence IOL manufacture.
