Many thanks to Doctor Loden and his amazing staff! They made something that would otherwise be very intimidating very comforting. Their professionalism and service was off the charts. I am one day post surgery and am pain free and can see better than I have for twenty years. I would recommend them to anyone!

I am so thankful to Dr. Loden. My results from my LASIK surgery were instant. I don't have hardly any vision distortion and it 1 day post surgery, it will just keep getting better each day. I see better now than I've ever been able to with glasses or contacts. I so recommend Dr Loden!!!

Provided by Citysearch - Thanks to Dr. Loden and his staff. I had ILASIK yesterday with the guarantee that I would have 20/20 or better. Now it's the day after and sure enough I have 20/20 in both eyes and Dr. Loden says ""it will only get better."" Everything he has said has been spot on so there is no need to doubt him now. His staff was the nicest people I've ever met in a business environment. If anyone deserves a award it would be Loden Vision Center.
