Thomas Castillo states, "I want my patients to know that I have always been committed to providing the latest in quality eye care. I was the first ophthalmologist to implant folding intraocular lenses in the Quad Cities, something which is now the standard in cataract surgery. Dr. Wilkins and I routinely implant the best IOL's possible for our patients, always attempting to give them the best vision possible".
