Our President & CEO

Dr. Pit Gills a cataract surgeon and board-certified ophthalmologist, is also fellowship-trained in cornea surgery and disease. Since joining St. Luke’s in 2001, his skill, extensive training, and experience with many types of intraocular lenses and latest laser technologies have allowed him to provide his patients with the most current treatment advancements. At the same time, his philosophy is to practice balance and restraint – drawing on his broad spectrum of specialties – to tailor each treatment for each individual and knowing when to use, and when not to use the latest technologies.


In addition to treating current patients and leading the team of cataract surgeons at St. Luke’s, Dr. Gills is engaged in developing new techniques that will benefit patients in the future. He has participated in multiple clinical studies and FDA trials of intraocular lenses and has published articles in key scientific journals and medical textbooks. Dr. Gills also shares his extensive surgical experience through presentations to colleagues at major scientific symposiums.


Today, as President and CEO of one of the largest freestanding ambulatory eye care centers in the United States, Dr. Pit Gills has performed more than 60,000 cataract surgeries making him one of the most sought-after cataract surgeons in Florida. Dr. Pit Gills approaches each patient as if they were a member of his family, asking himself, “What would I do if this was my mother, my brother, or my sister?” This philosophy is what has made St. Luke’s the choice of patients from over 77 countries.

  • My cataract surgery was a great experience all the way around! The offices are shiny and clean as well as the service areas. Professional staff treated us very well from the moment we walked in the door to the moment I walked out of the surgical suite! I was even given a medicine chart which made it easy to keep track of when and how many eye drops over the six weeks. It’s been a year and a half and my eyesight couldn’t be better – no problems, no glasses, even for reading.

  • Dr. Pit Gills identified an eye condition I have that no other eye doctor had ever mentioned, and he took the necessary precaution to address it during surgery. Dr. Pit Gills also patiently answered all my questions, and I came with a list! Forever grateful.

  • Painless perfection best describes my experience with Dr. Pit Gills and St. Luke’s. My vision was restored to an incredible state which permits me to see like a youngster, and I am 80!

    — Charles J.
  • I had an outstanding experience with Dr. Pit Gills. Highly recommended! Actually, traveled and drove over 2000 miles (roundtrip) three (3) times for diagnosis, surgery, and follow-up. Would gladly do it again. Everything was great and the cataract surgery has far exceeded my expectations. St. Luke’s is also a wonderful Christian hospital. My prayers answered in being able to see again like when I was a kid without glasses. You are treated cordially and lovingly as a whole person!

    — Dr. Rick Klobuchar - Virginia Beach, VA
  • After receiving treatment from Dr. Gills, I tossed my glasses and read the paper, drive at night and tie a fish hook on my line. I could not have ask for anything better. I tell people if they want the best sight then go to the best, like I did. His staff is top notch. His office/clinic is very impressive. All of this with no pain or discomfort.

    — Jim - North Port, FL
  • Having cataract surgery with Dr. Pit was just like clockwork. Everyone was so nice and they kept me informed as to whatever the next step would be in preparation. I felt calm and was assured the procedure would be O.K. I especially appreciated the assistant having prayer before the surgery and knowing I was surrounded by Christians. My follow-up appointments were just as easy. I would recommend St. Luke’s to any one.

    — Peggy - Spring Hill
