Sugarland Eye & Laser Center believes in offering the latest in technology to our patients. This helps our patients obtain unsurpassed results. Refraction literally refers to the bending of light as it passes between two substances. In ophthalmology, the term refers to measuring what lenses manipulate light in a way that achieves the patient's full visual potential. In simpler terms, it is the measuring of the patient's glasses prescription. Patients often feel quite confused during refraction. When asked to choose between two lenses, patients often cannot decide which is clearer of the two. Patients can now rest assured that their responses are being verified with our state-of-the-art autorefractor. This instrument's sophisticated sensors detect how light is moving through the eye. With its amazing precision, the sophisticated autorefractor reports its calculation of your glasses prescription. This data is correlated with the patient's responses to ensure accuracy. Now, you can relax during your examination knowing that your responses are being cross checked with this and several other technologies.
