[7] Later that year, the college began construction on its main clinical facility, The Eye Institute (TEI), which opened in 1978 to serve as a training site for the school's optometry students and as a community vision care center for the public.

In 2000, PCO became the first school of optometry in the county to offer a Doctor of Audiology (AuD) degree when it received approval by the Commonwealth of Pennsylvania.

The Pennsylvania Ear Institute (PEI), the clinical facility of the program, was opened on November 19, 2004, shortly before the school's first class of AuD students would begin their four-year curriculum.

Over the years, the university has added programs such as Physician Assistant Studies (PA), Occupational Therapy (OT), Biomedicine and Speech-Language Pathology (SLP).

In addition to its main West Oak Lane clinical facility, TEI has a satellite location in the Chestnut Hill section of Philadelphia.
