Computerized Refraction Q & A

G. DENNIS LEAKS, OD LTD

What is computerized refraction?

Refraction refers to the way light is deflected inside the eye. Normally when light enters the eye, it passes through the cornea and the lens before converging at the light-sensitive retina. Sometimes though, aberrations in the cornea, lens, or other structures can interfere with the way light reaches the retina, causing it to converge in front of or behind the retina.

These vision problems are referred to as refractive errors, and they include myopia, hyperopia, and astigmatism. Refractive testing is performed to measure how well your eye refracts light and to determine if you have a refractive error that needs to be corrected with lenses.

Traditionally, refractive tests were performed manually, but today, computerized refraction uses state-of-the-art technology to obtain highly accurate and precise refractive measurements. The computerized refraction system is sometimes referred to as an autorefractor.

What happens during a computerized refraction exam?

Like traditional refraction that uses manually controlled dials and lenses to assess your eyes, computerized refraction is completely painless and noninvasive. During the test, you’ll sit in front of the imaging machine and rest your head or chin against a support to steady your vision. You’ll focus on a light that’s directly in front of you while the machine does all the rest. Computerized refraction is usually performed as part of a comprehensive eye exam, but it can also be performed as a “standalone” procedure to assess your need for glasses or contact lenses, or to determine if a current prescription needs to be adjusted to accommodate a change in your vision.

What technology do you use for the computerized refraction portion of the exam?

At G. Dennis Leaks, OD, LTD, we use the KR-800 Auto Kerato/Refractometer and the i.Profiler®plus to perform computerized refraction exams. The KR-800 represents the latest in design technology, featuring rotary prism technology for greater accuracy and precision. The i.Profilerplus is a 4-in-1 system that includes an autorefractometer, a corneal topography system to map the corneal curvature and surface, a keratometer to identify and measure astigmatism, and an ocular wavefront aberrometer. Aberrometers are routinely used in LASIK surgery, but today, eye doctors also use the technology to detect small vision problems by measuring the way light travels through the eye. The i.Profilerplus uses a completely automated system to perform all measurements in both eyes in about a minute.
