  2. Recognize adverse reactions to ocular drugs and apply the appropriate response.
  3. Safely administer ophthalmic pharmaceuticals under physician supervision.

Course Activities and Design

The class will be presented by means of lecture/discussion, audio-visual presentations, handouts and demonstrations.
 

Outcome Assessment Strategies

At the beginning of the course, the instructor will detail the methods used to evaluate student progress and the criteria for assigning a course grade. The methods may include one or more of the following tools: examinations, quizzes, homework assignments, research papers.
