Medical and Specialty Contact Lenses

The clinicians at the USC Roski Eye Institute provide unique expertise and over a decade of experience in fitting a variety of specialty contact lenses, including rigid gas permeable, hybrid, multifocal, and scleral contact lenses. These special lenses are often used to treat patients with irregular cornea shape and dry eyes that have not responded to traditional therapy.

In addition to many types of specialty contact lenses, USC Roski Eye Institute offers Prosthetic replacement of the ocular surface ecosystem (PROSE) treatment, a non-surgical option for patients who suffer from serious corneal conditions and ocular surface diseases. PROSE treatment utilizes a software program that allows the clinician to design highly customizable devices for complex eye shapes and surfaces. The USC Roski Eye Institute is one of 2 locations in California to offer this treatment, and one of only 16 nationally.

Patient Testimonials

PROSE therapy reduces symptoms, supports healing and improves vision through the use of a prosthetic scleral device that is tailored for each individual eye. Literature has demonstrated that patients who have received this pioneering treatment experience a notable improvement in their quality of vision and quality of life as a result.

BostonSight PROSE patient Lisa Berlin considers herself to be very fortunate. In her own words: “PROSE and Dr. Gloria Chiu at the USC Roski Eye Institute have both made such a difference in my life that it is hard to measure! When I insert my PROSE lenses, I eliminate pain, attain visual clarity, lubricated corneas and an all-around better quality of life! Dr. Chiu is brilliant, kind, caring and always goes the extra mile to try and help me with any of my eye issues (and I have many!). Because of Dr. Chiu and PROSE lenses, I now have relief from the pain of dry eyes and the scarring!”
