Medical Eye Center Providers

Following medical school, ophthalmologists complete three years of comprehensive training in the diagnosis and treatment of eye diseases and abnormalities. Many doctors begin practicing as soon as they have finished their residency. Some ophthalmologists, however, choose to pursue a fellowship, which is an additional year of training that makes them experts in a specific area of the eye. This level of further education is generally considered optional, but our doctors all prioritized additional training in order to provide the best possible care to their patients. While it is rare to find a practice with even one physician who has completed advanced training, many of the doctors at Medical Eye Center are fellowship-trained.

Dr. Paul Jorizzo and Dr. Helen Koenigsman have advanced glaucoma training;

Dr. Matt Oliva and Dr. John Welling are the only fellowship-trained cornea specialists in southern Oregon;

Dr. Craig Lemley has advanced training in the medical and surgical management of vitreoretinal diseases.

Our specialists each explained the benefits of their advanced training to give you a better idea of the level of skill and knowledge they gained through additional education.

Dr. Koenigsman

“Here at Medical Eye Center, we offer the tried-and-true treatments for a multitude of eye diseases. We are continuously updating our skills and training to also be able to offer the latest advances. I am involved in clinical research trials that allow patients to have access to technologies and treatments that are not yet widely available. My education did not end with my fellowship in glaucoma; learning is a continuous process.”

Dr. Lemley

“Treatments for common vitreoretinal disorders are evolving rapidly, and advanced training has enabled me to provide state-of-the-art care. In addition, the techniques used in vitreoretinal surgery are highly specialized, and advanced fellowship training is paramount in managing these highly complex diseases.”

Dr. Oliva

After pursuing an international fellowship, Dr. Oliva spent a year in Melbourne, Australia to complete his intensive training in the diagnosis and treatment of corneal diseases and abnormalities. “My fellowship really prepared me to offer the latest in cornea transplant techniques and the other complicated cornea issues we treat here.”

Dr. Welling

“I was fortunate to complete two fellowships - one in cornea, cataract, and refractive surgery and the other working in Africa and Asia with the Himalayan Cataract Project. These fellowships enabled me to acquire very specific skill sets and also broaden my exposure to a wide variety of pathology in high volume settings. I hope to utilize this training to improve my patients' quality of life.”

Dr. Jorizzo

“During my residency, I had an opportunity to spend an additional year working with one of the leading authorities in the treatment of diabetic retinopathy and age-related macular degeneration. Later on, I became particularly interested in glaucoma. I did a formal glaucoma fellowship after residency to enhance my ability to diagnose and manage glaucoma using medical, laser, and surgical modalities. At the Medical Eye Center, I enjoy a practice that blends cataract, glaucoma, and retina interests.”
