Medical Eye center History

Our History
For over 100 years, the doctors of Medical Eye Center have been providing a level of care and experience that you won’t find anywhere else.


When Dr. Jocelyn J. (J.J.) Emmens, Medical Eye Center’s founding physician, left his active Eye, Ear, Nose, and Throat practice in Philadelphia for a new life out west; he could never have foreseen the legacy he was creating.

Building a Strong Foundation
Dr. Emmens established his new Rogue Valley office in 1911 and became renowned for his skill as a surgeon and diagnostician. Joining with other area physicians in 1921, he helped found the Jackson County Medical Society, where he served on the three-member bylaws committee. In addition to his active professional life, Dr. Emmens participated in many civic affairs; he served as a member of the city council from 1916 to 1919 and was involved in the Chamber of Commerce, leading the membership drive that brought the local organization to a metropolitan standing. Dr. Emmens passed away in 1934.

Dr. Emmens’ two sons, Thomas and Robert, also achieved local fame. Dr. Thomas H. Emmens followed in his father’s footsteps and joined the practice as an Ophthalmologist. Devoted to his Oregon home until his final days, Tom died in 1959.  After cheering on the University of Oregon football team against Stanford, he choked to death on a piece of steak while having dinner at a restaurant.  The doctors he was with all thought he had a heart attack. This was before the Heimlich procedure was invented.

Robert (Bob) Emmens joined the Army and served in the 17th Bomber Group. Four months after Pearl Harbor, as a member of the “Doolittle Raid,” he landed in Russia on a secret intelligence mission. They had personal orders to test Stalin’s resolve in not allowing US attacks on Japan to be initiated from Russia. After a career in the Air Force, he retired to Medford, where he became a realtor and a piano player at several local venues.

As the years passed and medicine became more specialized, the practice began to focus primarily on eye care. Dr. John T. Weisel joined Medical Eye Center in the late 1950s, and he worked with Dr. Emmens for a short time before he passed away. Dr. John Retzlaff was a local internist who decided to change fields, did an ophthalmology residency, and eventually joined Dr. Weisel.

Taking Cataract Care to a New Level
By 1968, Medical Eye Center was helmed by these two highly respected eye surgeons whose experience was soon respected worldwide. Drs. Weisel and Retzlaff were early pioneers in cataract removal and lens implantation whose work contributed to the approval of the intraocular lens by the FDA. In 1974, they also performed the first cataract extraction by phacoemulsification in Oregon. This process was the latest advancement in cataract removal at the time. It involved using an ultrasonic probe that vibrates 40,000 times per second and causes the cataract to disintegrate into tiny particles, which are then removed through a suction instrument. Until that time, patients were required to stay in the hospital for a few days, but phacoemulsification allowed smaller incisions and a shorter, safer, post-operative course. This was a considerable advance toward modern cataract surgery.

Dr. Weisel traveled the world lecturing to other doctors and teaching them to perform the delicate surgery of removing cataract-damaged lenses and replacing them with plastic ones. Those doctors have, in turn, led the technique to many others, helping to refine surgical skills among their peers.

Dr. Retzlaff was an esteemed lecturer and researcher. In the mid-1980s, he helped develop a technique to determine the proper lens power in cataract implants after the old lens is removed. Eye surgeons worldwide still employ the SRK formula, of which the “R” stands for Retzlaff. He was also one of five doctors to participate in FDA research of a drug called bendazac for use in halting cataract development.

Medical Eye Center thrived under Weisel’s and Retzlaff’s leadership. They eventually recruited Dr. Philip Paden, Dr. Paul Jorizzo, and Dr. Paul Imperia, and a new building was constructed in 1989 to accommodate additional technology and an increasing number of patients. This building featured education and patient counseling areas, in-office surgical suites, and the RVMC Eye Lab, providing the latest lasers and fluorescein angiographic equipment on the Rogue Valley Medical Center campus.

Our pioneer in laser vision correction surgery and the first fellowship-trained cornea surgeon, Dr. Paul Imperia, started his career at Medical Eye Center by performing Radial Keratotomy (RK) surgery.  RK predated LASIK and relied on the steady hand of the surgeon.  Dr. Imperia participated in the original FDA studies for LASIK and brought the first excimer laser to Southern Oregon in 1996.

To meet expanding patient interest, he invested in an FDA-approved mobile transport system for the excimer laser used in LASIK. He developed satellite offices in Bend, Redding, Grants Pass, and Eureka.

An affiliated ophthalmologist with the Himalayan Cataract Project and Surgical Eye Expeditions, Dr. Imperia worked in Nepal, Ethiopia, Honduras, and Christmas Island, providing surgery and teaching modern surgical techniques. Locally, Dr. Imperia spearheaded the development of a free eye clinic in partnership with La Clinica, providing routine eye care, glasses, and surgical procedures to low-income and uninsured patients. He also led a team that provided outreach screenings at seasonal migrant worker camps. He retired from Medical Eye Center in 2018.

Dr. Paul Jorizzo

Dr. Paul Jorizzo graduated from Union College in Schenectady, New York, and medical school at the University of Rochester School of Medicine. Moving to the west coast, he completed five years of ophthalmology training at the Oregon Health Sciences University including: ophthalmology residency, a one-year medical retina fellowship, and a formal fellowship in glaucoma.

In 1988 Dr. Paul Jorizzo joined MEC as the first subspecialist, ushering in a new era of modern glaucoma and medical retina care. Dr. Paul Jorizzo became one of Southern Oregon’s most sought-after cataract and glaucoma specialists, and our region’s only board-certified ophthalmic surgeon with advanced fellowship training in both glaucoma and retinal diseases including diabetic retinopathy and macular degeneration. Along with his colleagues at the Medical Eye Center, he offered the latest intraocular lens technologies and surgical techniques.

Jorizzo became director of the glaucoma service in 1988 at the Medical Eye Center in Medford, Oregon. During his time as Director of Glaucoma, Dr Jorizzo played a hand in many instances of growth within the practice, opening the first in Oregon to be AAAHC accredited facility in 1996, in 2005 Medical Eye Center became first to offer premium IOL in the region, later becoming the first to offer IntraLase and Lipiflow and again later performing first light adjustable lens implants in our region. 

Dr. Jorizzo & his children have participated in international eye surgical expeditions in Peru, Kiribati & multiple locations in Ethiopia. In addition to teaching & treating cataract & glaucoma patients, they have enjoyed photographing their experiences for Himalayan Cataract Project working in Nepal, Ethiopia, Rwanda & Ghana.  

He also works extensively with Pacific Islands Medical Aid (PIMA) and Surgical Eye Expedition International (SEE International) providing surgical eye care in the Pacific Islands. 

Dr Jorizzo retired after a lengthy career and 30+ years in Opthalmic practice in December 2022. Dr. Jorizzo enjoys photography, fly fishing, and exploring the world with his family.  


In addition to advanced care, Medical Eye Center offers the latest technology in comfortable, custom-designed eye care facilities.

Laser and Surgery Center
In 1996 Medical Eye Center opened a 5000 square foot Ambulatory Surgery Center (ASC) with two operating rooms—the first ASC in Oregon to be AAAHC accredited. Our current Laser and Surgery Center spans over 8,000 feet and holds four operating rooms, with one operating room approved for general anesthetics.  

Medford Office

In October 2009, Medical Eye Center’s new 38,000-square-foot building was erected at Barnett Road and Highland Avenue. The custom-designed facility further improves and expands Medical Eye Center’s services. Thanks to thoughtful planning, the new building allowed for expansion of surgical capacity and created more room for new state-of-the-art diagnostic equipment, a more extensive optical department featuring the latest styles in fashion eyewear, a unique LASIK surgical suite, and a results-oriented medical spa, and more.

Volunteering Abroad
Every year Medical Eye Center surgeons travel abroad to countries such as Honduras, Peru, Nepal, Kenya, Ethiopia, and Christmas Island to perform operations for individuals who would otherwise have lost their sight due to a lack of resources. This humanitarian work reminds the doctors of why they became ophthalmologists. In addition to training surgeons in developing countries, MEC doctors also host both U.S. and international surgeons in their Medford office, offering advanced training to other regional eye care providers.
