![]() ![]() Retinoscopy performed by an experienced clinician has been found to provide a more accurate estimation of refractive error than autorefraction. Objective refraction can be performed with static retinoscopy, which requires cycloplegia, or dynamic retinoscopy both require the judgment of a human operator to determine the refractive error. This method does not require any input from the patient: instead, instruments such as Retinoscopy, Auto-refractometer and Aberrometer are used to calculate objectively the refraction. Ocular refraction can be determined with a technique called "subjective refraction", which requires the patient's collaboration, and/or with the "objective refraction" technique.
