As an eye doctor in Peachtree City, Dr. John Henahan invests in continuing his training and in adding new technology when it can make a difference in the vision of his patients.
In 2012, Spectrum Eyecare has made a major investment in equipment to enhance Dr. Henahan’s ability to spot early signs of potentially blinding eye diseases including glaucoma, macular degeneration and retinal diseases.
This new machine manufactured in Germany by Zeiss is called an HD-OCT (Optical Coherence Tomographer). It has the ability to capture images of eye tissue at a near individual cell level of resolution. In addition, it can show each layer of tissue in the eye allowing Dr. Henahan to pinpoint the exact location of tissue damage.
In the past few years, HD-OCT has allowed breakthroughs in the diagnosis and treatment of a variety of eye diseases. Until recently, these devices have largely been found only in medical schools and research centers. Dr. Henahan realized that this device would allow patients to receive care in Peachtree City that in the past would require a referral to a specialist in Atlanta.
Dr. Henahan chose Zeiss because they are the clear leader in this technology. “Zeiss has an extensive database to compare patient results to. Without this database, we are looking at raw data that has little value because we don’t know if it deviates from normal or not. The Zeiss HD-OCT allows us to know at a glance if we need to be concerned or not about a finding”, says Dr. Henahan.
In addition, patients with vague visual complaints that have defied diagnosis in the past may finally get an answer regarding their visual complaints when this technology is used in conjunction with a comprehensive eye examination.
“It helps me be a better eye doctor, plain and simple”, says Dr. Henahan. “Really, it is like having an MRI of the eyes. With baby boomers coming of age, OCT will help us do a better job at detecting eye diseases before the damage becomes permanent.”
The scan only takes about five minutes and is non-invasive. “Nothing touches your eye, no drops are needed and it doesn’t hurt at all”, says technician Lorraine Ruiz. In most cases the cost of the procedure is filed to the patients medical insurance. Even if the insurance does not cover the test, it is relatively inexpensive; costing around $50 says Dr. Henahan.
At Spectrum Eyecare, they take a comprehensive approach to eye care including checking blood pressure, blood sugar, evaluating all parts of the eye and using OCT when indicated to be sure that they are taking the best possible care of a patient’s most important sense, vision.
If you know of someone who might benefit from the comprehensive approach to eye exams that Dr. Henahan and his staff at Spectrum Eyecare take, feel free to contact the office at 770-487-0667. They accept most major medical insurances as well as Medicare.
Dr. Henahan became an eye doctor in 1991. He founded Spectrum Eyecare in 2008. He lives with his wife Lisa and their two sons right here in Peachtree City.
