The field of low vision and neuro-optometric rehabilitation is very rewarding. There are constant struggles that an individual with these disorders faces as part of their ""normal"" life. Difficulties range from cooking and laundry to bill paying and shopping, and solutions to all of these concerns are readily available. Through rehabilitation and education we can make a significant improvement in the patient's confidence and independence. The low vision exam works in coordination with a patient's regular optometric exam.

During a low vision evaluation, we determine the individual goals and struggles the patient notices and then work on viable solutions. Once we have developed a plan, the patient returns to his or her general optometrist for all future care. Patients who have had traumatic brain injury or who suffer from a neuro-degenerative disease have specific concerns and needs regarding balance and visual perception. These needs are ongoing and ever changing, but a variety of solutions exist to aid in meeting patients' needs.

Terria L. Winn, MD is a board certified ophthalmic surgeon specializing in cataract and implant surgery.

She was one of the first eye surgeons in Wichita to use topical anesthesia, starting in 1996. Her standard surgical technique utilizes eye drops to “numb” the eye and a no stitch, no needle approach, allowing the patient to leave the operating room without a patch and eliminating the need to stop “blood thinners.”

Dr. Winn was the first surgeon in Wichita, and one of the first in Kansas to implant the Acrysof foldable intraocular lens after receiving FDA approval in the mid 1990s. She was also the first in Wichita and the surrounding area to implant the Acyrysof Toric intraocular lens that corrects astigmatism.

Aside from being known for her surgical skills in advanced microincision cataract surgery, Dr. Winn is probably best known by her professional peers and patients for her kindness, personal attention, and contagious smile. This validates her practice philosophy, “A Special Kind of Care.”
