She gives a thorough and effective eye exam and has the ability to use the results effectively when prescribing new lenses. She was able to increase strength of prism as needed and remove astigmatism prescription when no longer nShow moreeeded. I look forward to soon receiving my new glasses. She answers questions when asked, is kind and caring when doing the exam, and I am grateful for having had the opportunity to be under her vision care.

Great results from my first cataract surgery. The anesthesiologist gave me something to help me relax during surgery. Day 2 and no pain, just a little awareness that something feels slightly different about my eye but not scratchy in any way.
