Helping patients seeking Custom Cornea LASIK and PRK in Portland and the surrounding area


Casey Eye Institute
Casey Vision Correction Center surgeons have more than 60 years combined experience in laser vision correction. Our center pioneered laser refractive surgery in the Pacific Northwest, performing the first excimer laser procedure in 1994. Dr. Mathers, Dr. Fraunfelder, Dr. Chamberlain and Dr. Huang all have completed advanced specialty training in caring for the cornea, the part of the eye reshaped by LASIK. They are dedicated to ensuring the health of your eyes and maintaining the excellence Casey Vision Correction Center patients have come to expect.
Dr. Mathers and Dr. Fraunfelder are leading authorities in the field of cornea care. They are currently serving as professors of ophthalmology at Oregon Health and Science University. Sought-after lecturers, Dr. Mathers and Dr. Fraunfelder also frequently share their laser eye surgery expertise with other physicians at national and international conferences and in our facility. Dr. Huang is a Harvard graduate who obtained his training at the world renowned Doheny Laser Vision Center, where he served at the center's Director, Chair of Corneal Laser Surgery and Associate Professor of Ophthalmology and Biochemical Engineering.
Casey Vision Correction Center offers surgical expertise, outstanding patient care and leading-edge technologies to provide patients with rewarding vision correction results. To schedule a one-on-one consultation with Dr. Mathers, Dr. Fraunfelder, Dr. Chamberlain or Dr. Huang and learn more about your vision correction options, call (866) 804-7217.
More About the Casey Laser Center
Casey Vision Correction Center is part of Casey Eye Institute at the department of Ophthalmology at Oregon Health and Science University (OHSU). OHSU is Oregon's leading health and research university, boasting a rich tradition of academic excellence, leading-edge research and high quality patient care.
In 1991, Casey Eye Institute opened its own freestanding building, bringing together impeccable patient care and the latest research with state-of-the-art surgery suites under one roof. The institute is widely recognized as a leader in developing new treatments for eye diseases. Casey Eye Institute is among the top recipients of U.S. research grants to eye centers, and is only one of seven regional centers sponsored by Research to Prevent Blindness the nation's leading health organization supporting eye research.
Dr. Mathers, Dr. Fraunfelder, Dr. Chamberlain and Dr. Huang are experienced in a variety of laser vision correction techniques. They offer blade-free LASIK, which uses the IntraLase laser instead of a mechanical blade to create the corneal flap. The IntraLase technology allows them to achieve a highly precise, accurate treatment. Casey Eye Institute's surgeons also specialize in the sophisticated CustomCornea LASIK procedure, whereby a special wavefront technology is used to create a detailed 3-D map of the patient's cornea. The surgeons use this map to precisely program the excimer laser, which gently reshapes the cornea so that it can refract light rays properly. The result is a highly customized treatment that often leads to better vision correction results.
For certain patients who are not candidates for LASIK, Dr. Mathers, Dr. Fraunfelder, Dr. Chamberlain and Dr. Huang recommend and perform the photorefractive keratectomy (PRK) procedure. This laser vision correction treatment is suitable for a range of patients who cannot undergo LASIK because of their large pupils and/or thin corneas. During your personal consultation, Dr. Mathers, Dr. Fraunfelder, Dr. Chamberlain or Dr. Huang will help you decide which laser vision correction procedure is right for you.

Each patient receives personalized care at the Casey Eye Institute.
