The Jules Stein Eye Institute offers fellowship training to enable particularly well-qualified persons to receive and contribute to training in specific areas of ophthalmology. Clinical fellowship training combines outpatient, inpatient and surgical experience in an ophthalmic subspecialty. The fellow assumes increasing responsibility for patient care, under the supervision of faculty members responsible for the program. In addition to receiving instruction from faculty, the fellow instructs medical students and residents. Research is considered an important aspect of specialty training and a major prerequisite for assimilating future developments in ophthalmology. Fellows are expected to undertake independent investigation or to participate in one of the ongoing research projects in a basic or clinical field related to their specialty. Time is allotted appropriately for this experience, and its value is enhanced by careful supervision, availability of laboratory facilities, and access to technical assistance.
