“Using the patient’s own stem cells is a big step for regenerative medicine,” said Dr. Jurkunas, who is Associate Professor of Ophthalmology at Harvard Medical School, and an affiliate faculty member of the Harvard Stem Cell Institute. 1 In the past, stem cells were harvested primarily from cadavers. More info. “With this clinical trial, we hope to pave the way for better care for patients with corneal blindness, who have long needed better solutions for their condition.”.

In the CALEC procedure, the surgeon takes stem … Altogether, a total of four out of the five patients enrolled in this phase of the study received a CALEC transplant. How does the COVID-19 Pandemic Compare to Other Pandemics? In this interview, Dr. Gina Poe speaks to News-Medical about why we sleep, and the importance of REM sleep for brain development. Once the cells had grown to cover the membrane and the graft was ready for transplant, Dr. Jurkunas performed extensive scar tissue removal and transplanted the CALEC onto the cornea. In light of Preparing for a New Landscape – Dealing With Chronic Eye Disease & COVID-19, Smart Contact Lens with Dynamic Artificial Iris, Most Ophthalmologists Support Efforts to Reduce Medicine’s Big Carbon Footprint, First Fourier Transformed Optic Technology In The IOLs. Owned and operated by AZoNetwork, © 2000-2020. The entire process takes approximately 3 weeks before the limbal stem cell graft is ready to be sent to the operating room at Mass Eye and Ear where Dr. Jurkunas performs the transplant procedure," said Dr. Ritz. News-Medical.Net provides this medical information service in accordance So many conditions have to be just right so that the cells grow and the patient is safe. More recently, they came from autologous sources and live donations from relatives. With this clinical trial, we hope to pave the way for better care for patients with corneal blindness, who have long needed better solutions for their condition. These patients will continue to be followed over the longer term to monitor their progress. If we continue to be successful we will be able to give these patients with this condition a healthy surface of the eye -- and possibly even restore vision to some," said Dr. Jurkunas. The technique does not carry the risk of rejection like some other procedures because the cells are taken from the patient's own body. The cornea is the clear, outermost layer of the eye responsible for maintaining a smooth surface for normal vision.
