Certified Paraoptometric Practice Test

Which of the following is a common test performed by paraoptometric staff?

1. Refraction test

2. Laser eye surgery

3. Vision therapy

4. Corneal transplant

The correct answer is: Refraction test

The refraction test is a common procedure performed by paraoptometric staff, as it is a fundamental task in the assessment of a patient's vision. This test is designed to determine the appropriate prescription for glasses or contact lenses, and involves the use of various tools and techniques to measure how light rays are focused on the retina. It requires specialized knowledge about optics and the various factors that can affect vision. In contrast, procedures such as laser eye surgery, vision therapy, and corneal transplants are more complex and typically require a licensed optometrist or ophthalmologist to perform. Laser eye surgery involves altering the cornea to correct refractive errors, while vision therapy is a regimen designed to improve specific visual skills, including eye coordination and focusing, and corneal transplants involve surgical replacement of a damaged cornea. These tasks are beyond the scope of paraoptometric duties, which primarily assist in preliminary vision assessments and support the optometric practice.
