Dr. Keisler actually saved my life. He caught a severe bacterial infection (Pseudomonas) caused by a corneal abrasion, he responded swiftly and with great care. Not only did he save my vision, his quick response prevented the infection from spreading (to my brain). I can’t speak highly enough of him as a doctor and as a person.
