Physician assistants in ophthalmology: a national survey.

Fifty-two physician assistants employed in ophthalmologic practice throughout the United States were identified. Demographic and role-delineation data from 40 PAs agreeing to participate in the study were collected by questionnaire and telephone interviews. The data indicated that the majority of ophthalmologic PAs are employed in large practices that specialize in cataract and radial keratotomy procedures and that those practices are primarily located in the Southeast and Gulf regions of the United States. The authors conclude that most PAs are being utilized appropriately by ophthalmologists, that more formalized educational and credentialing programs may be necessary for the future, and that PAs can be positive adjuncts to ophthalmologic practice.
