Stem cell research has been a focus for doctors and health care researchers for more than 30 years now. While the research is generally complicated and sometimes slow-moving, there's one area of work where stem cells excel: eyecare. In fact, when it comes to eyecare, stem cell treatments have even helped some patients, like Anna Kuehl, who is profiled in a WebMD article about the treatments for macular degeneration. Head over to WebMD to learn more about stem cell research, how it's changing the world of eyecare, and what changes it might make to other areas of health care.
