An autorefractor is used to determine an individual’s prescription by measuring how light is affected as it reflects through the eyeball. The process is quick and painless for the patient, and the data ensures a baseline to determine the correct eyeglass or contact lens prescription.

How Does an Autorefractor Work?

The autorefractor shines light into the eye, measuring how it changes as it bounces off the back of the eye (the retina). Then, the patient is shown an image that moves in and out of focus. As reflections are made, several measurements determine when the eye is properly focused. These final figures determine the level of vision correction needed. Unlike many conventional refraction diagnostic devices, some autorefractors utilizes a unique wavefront technology algorithm based on Hartmann-Shack wavefront sensor, which analyzes many focal spots of a light wavefront. It can measure not just the basic refraction error of a patient, but to obtain a spatially resolved refraction map of the wavefront.

Types of Autorefractors / Keratometers

Latam Optical carries several auto refractors that are also built-in keratometers. This product duo determines eye prescription and measures the shape of the cornea. These capabilities are crucial for diagnosing eye conditions such as astigmatism or corneal distortion. They are also especially helpful for fitting contact lenses. Here is our auto refractor/keratometer lineup:
