Corey Haas, 8, cries after getting eye drops shortly before he enters surgery at the UPenn Medical Center in Philadelphia, PA on Thursday, September 25, 2008. The red X above his left eye marks the eye that gene therapy surgery will be performed on. Corey is sight-impaired and will undergo surgery injecting genetic material into his left eye in hopes of improving his vision.
