Course Description

Provides ongoing and advanced clinical education experience in local ophthalmic practices and health care facilities under the supervision of facility personnel. Includes exposure to working conditions and skills needed while performing ophthalmic diagnostic and therapeutic procedures.

Addendum to Course Description

Students are assigned to one or more clinic sites for the entire term.  Each weekly rotation consists of 20-24 hours, the clinic site(s) are selected by the course instructor.  The assignment hours for each clinic are based on clinic schedules.

Students are required to wear attire conforming to the requirements set forth by the Ophthalmic Medical Technology Program.  Apparel shall consist of  a department approved navy blue scrubs, with PCC ID badge.  These items are purchased by the student in accordance with the guidelines provided by the course instructor.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  1. Demonstrate ongoing and advanced-level skill as an ophthalmic technician in a clinical setting.
  2. Demonstrate the use of a variety of diagnostic tests offered in the clinical setting and understanding of diagnostic procedures.
  3. Perform patient work-ups and provide patient education in a clinical setting independently, and then have verified by the preceptor.
  4. Participate as a team member in an ophthalmic practice.
  5. Improve clinical and communication skills based on feedback and knowledge acquired from previous clinical experience.

Aspirational Goals

The goals are to enable the student to:

  1. Gain experience in ophthalmic offices.

  2. Make the transition from theory to practice as an ophthalmic technician.

  3. Gain direct work experience with experienced clinical office personnel and observe working relationships within an ophthalmic office.

Course Activities and Design

Grades and competency will be determined according to the student's ability to demonstrate theoretical understanding, technical performance, and professional growth. The student must progress by assisting the ophthalmic technician or ophthalmologist in basic procedures. The student will be directly supervised at all times. Students will demonstrate acceptable patient care, and the ability to follow directions. These traits must be demonstrated satisfactorily to progress to the next level.

Outcome Assessment Strategies

Assessment will be based on verbal and written progress reports at the clinical setting and in the campus laboratory. Evaluation criteria is based on daily performance, professional development, attitude, communication skills, attendance and interpersonal skills demonstrated with patients and office personnel. Students will receive an evaluation of their technical skills as well as their overall performance by the site supervisor after each practicum experience.

The grading system for the course is "Pass" or "No Pass" .  In order to receive a "Pass" grade, the student must:

    1. Satisfactorily complete the clinical rotation.

    2.  Receive a satisfactory evaluation (both clinical and interpersonal skills) from each of    the work supervisors.

          3.  Complete all of the time assigned 180 hours.
