Which of the following methods is primarily used for objective refraction? A) Visual acuity testing B) Refraction using subjective input C) Contrast sensitivity assessment D) Keratometry
Understand the Problem
The question is asking to identify the method that is mainly used for objective refraction from the provided options. Objective refraction involves determining a person's refractive error without requiring their subjective input, which typically involves methods objectively measuring the eye's focusing system.
Answer
Keratometry
The final answer is Keratometry.
Answer for screen readers
The final answer is Keratometry.
More Information
In objective refraction, methods like keratometry and the use of autorefractors are generally employed. These methods do not rely on patient input and are therefore considered objective.
Tips
One common mistake is confusing subjective refraction methods with objective ones. Remember that subjective methods rely on patient feedback while objective methods do not.
