Course Description

Provides 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. Students must enroll in this course if they are enrolled in the second year seminar. May be repeated two times for credit.

Addendum to Course Description

Students are assigned to one office for the entire term.  Each weekly rotation consists of two(2) eight hour days in an office selected by the course instructor.  Exact hours during the clinical rotation day are determined by the office schedule. 
Students are required to wear attire conforming  to the requirements of the Ophthalmic Medical Technology program.  Apparel shall consist of a department approved blue lab jacket embroidered with the college name, college logo and the student's name.  Appropriate professional  dress will be worn under the lab coat.  These items are purchased by the student in accordance with the guidelines provided by the course instructor. 

Intended Outcomes for the course

Upon successful completion students should be able to:

1. Use knowledge and apply skill as an ophthalmic technician in a clinical setting.
2. Perform ophthalmic diagnostic tests.
3. Participate as a team member in the ophthalmic practice.
4. Perform patient work-ups and provide patient education in a clinical setting.

Course Activities and Design

Grades and competency will be determined according to 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. Student 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 (144 to 160 hours, depending on the term).
