        U.S. and Chinese scientists demonstrated that lens epithelial stem cells (LECs) could be used to regenerate a clear and functioning lens.

        Lens regeneration using endogenous stem cells with gain of visual function.
        They first showed the regenerative potential of LECs in a rabbit model and then went on to do a small (12-patient) trial on infants with congenital cataract. The lens capsule was preserved in the cataract surgery, which allowed a functional lens to regrow in 3 months. The authors are expecting to extend this surgical technique to treat age-related cataracts with the goal of eliminating the need for intraocular lens replacement.
