I trust Dr. Barker with my eyes - what can I say! I would hate to choose between my senses but I value optimum eyesight for all the obvious reasons and I had cataracts removed and lens implants inserted and I now have 20/15 vision and couldn't be happier. It's amazing how something artificial can feel so natural and improve what mother nature short changed you on. Thank you Mann for your quality work and trustworthiness. Don't go cheap on your eyes, go with someone you can trust implicitly and unhesitatingly. and that's Mann Eye Institute.
