Quite Simply, Dr. Kroll is THE best Eye Dr. in Las Vegas! I'd give him 10 stars if it was available. His staff is courteous and knowledgeable and Dr. Kroll takes the time every time you visit to provide you with a thorough, comprehensive diagnosis. They have the latest in frames and lenses and I learned how to insert contacts from his staff. I will continue to go to Dr. Kroll for many years and highly recommend him to anyone needing a great eye Dr.
