Stem Cells Regenerate Human Lens After Cataract Surgery, Restoring Vision

Approach may have broad therapeutic implications on tissue and organ repair

Researchers at University of California, San Diego School of Medicine and Shiley Eye Institute, with colleagues in China, have developed a new, regenerative medicine approach to remove congenital cataracts in infants, permitting remaining stem cells to regrow functional lenses.

The treatment, which has been tested in animals and in a small, human clinical trial, produced much fewer surgical complications than the current standard-of-care and resulted in regenerated lenses with superior visual function in all 12 of the pediatric cataract patients who received the new surgery.

Dr. Zhang receives NIH Director’s Transformative R01 Award

“Zhang and co-principal investigators Sheng Ding, PhD, from The Scripps Research Institute, and Thomas Reh, PhD from the University of Washington, received the highest possible scores for their proposal to investigate the regenerative potential of retinal cells.  Their long-term goal is to restore visual function lost through diseases such as macular degeneration and retinitis pigmentosa.”
