An autorefractor or auto refractometer is an ophthalmic device used to measure the refractive error of a patient’s eyes. It provides an objective measurement of the eye’s focusing power, helping eye care professionals to determine the correct prescription for glasses or contact lenses.

Key Features

• Automated measurement: Quick and accurate measurements with minimal patient input.
• Refractive error assessment: Measures sphere, cylinder, and axis values for astigmatism.
• Pupil size measurement: Some autorefractors can measure pupil size.

Uses

• Eye exams: Routine eye exams to determine refractive error and prescribe corrective lenses.
• Screening: Vision screenings in schools, clinics, or community settings.
• Pre-operative assessment: Measuring refractive error before eye surgery.

Benefits

• Accurate measurements: Provides reliable and consistent results.
• Efficient workflow: Streamlines the eye exam process.
• Easy to use: User-friendly interface for both patients and eye care professionals.
