Their efforts to share study opportunities with patients and to help bring new treatments to market contributes to breakthroughs that improve vision and enrich lives.

Studies are ongoing and fall into two categories: sponsored clinical trials, most of which are FDA-monitored; or investigator-initiated trials, studies sparked by our doctors’ desire to understand an already-approved technology better.

Vance Thompson Vision was the only practice I even considered for cataract surgery based on their stellar reputation. Dr. Morton and his staff were so professional, friendly, kind, and trusted. They were totally focused on me, my comfort, and good outcomes. My surgery went extremely well just as I knew it would. You won't regret using this outstanding practice.

From the moment I walked into the surgery center I was greeted, with a friendly smile, offered water or coffee and a comfortable seat. I only had to wait a few minutes to be asked to come to go in the testing area by an assistant. She was wonderful! Then I was shown a room to be greeted by the Dr. And his assistant in just a few minutes! I immediately felt at ease and both were very professional and explained the options and surgery procedure. We scheduled the surgery and again when I came to the surgery center, everyone was friendly, knowledgeable and made me comfortable when they dialated my eye and shortly brought me to the surgery area The Dr. came in very soon, performed the surgery, which was painless. When my eye was no longer dilated, I was amazed at how my vision was so much clearer! I would go back there for any eye surgery I needed!!
