A fundamental component of any ophthalmic practice, an autorefractor is a computer-controlled device that is used to objectively determine a patient’s eyeglass or contact lens prescription. Utilizing cutting-edge technology, this advanced instrument automatically calculates refraction, sphere, cylinder and axis values without any input from the patient. While an autorefraction can be useful for evaluating any patient, it is especially so for examining young children and disabled individuals who are unable to verbally respond.
The data generated by autorefraction can come very close to that obtained with subjective refraction. While subjective refraction will always produce a superior result, autorefraction provides valuable information that can be used by a practitioner as a reliable baseline for refining a phoropter examination, leading to a highly accurate prescription.
The technology behind autorefractors has continued to evolve over the years, and today’s models are very sophisticated. Some, such as the innovative Topcon KR8000 autorefractor-keratometer, are designed to accommodate very small pupils and irregular corneas, which can aid in the examination of cataract and post-refractive surgery patients.
Additionally, the latest generation of autorefractors employs fogging techniques that can prevent the patient from accommodating for the target, resulting in a more precise reading.
