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. 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!”

Treatment – PROSE Service

PROSE lensOur clinicians are expertly trained in PROSE technology, which originated at the Boston Foundation for Sight, in Needham, MA. The clinic is supervised by J. Bradley Randleman, MD and Gloria Chiu, OD, FAAO, FSLS, Boston Sight PROSE Clinical Fellow.

Please ask your eye care provider for a referral if you are seeking PROSE treatment. PROSE therapy is a long-term investment, as it requires multiple visits that involve preliminary consultation to determine candidacy, customized fitting, training on use and maintenance of the scleral device, and routine follow up visits.
