XO Exam ABT (Aberrometry)
The XO Exam™ ABT (Aberrometry ) exam unit, part of Xenon Ophthalmics™ world’s first medical-grade wearable ophthalmic exam system, is designed to improve patient care and increase practice growth.
XO Exam ABT offers three critical subjective aberrometry tests (Refractive Error, Wavefront Aberrometry, and Retinoscopy) with greater accuracy, speed, and patient comfort than conventional optical exam equipment.
For patients, that means greater access to the highest level of vision care available no matter where they are in the world. For practitioners, that means increased patient volume and practice growth without sacrificing the quality of care provided.
NEXT-GENERATION OPHTHALMIC DIAGNOSTIC TESTING
Multiple Refractive Error Tests in a Single Medical-Grade Device

Digital Phoropter
Our XO Exam ABT Aberrometry exam unit offers a paradigm shift in the subjective measurement for Refractive Error. Our custom liquid-lens technology goes beyond the latest digital phoropters for real-time true and accurate optical power change with a wide field of view while providing unmatched patient comfort.
With direct input using the convenient XO Remote, patients can move easily through cylinder, prism, and lens combinations, test their visual acuity, and provide feedback to increase accuracy while reducing test time.

Wavefront Aberrometry
Our XO Exam ABT unit offers accurate Wavefront Aberrometry, the objective method of measuring refractive power, using a tool to measure how a light beam moves through the tested eye.
The detailed measurements of the movement of the light wavefront are a critical tool in diagnosing low-order refractive errors like nearsightedness, farsightedness, astigmatism, and higher-order and refractive errors.
Higher-order errors refer to conditions that include complex visual defects such as coma, spherical aberration, and trefoil. These aberrations can cause difficulty seeing at night, glare, halos, blurring, starburst patterns, or double vision (diplopia).

Retinoscopy
XO Exam ABT offers precision Retinoscopy to examine the patient’s retina and provide an objective measurement of refractive error to determine if a patient suffers from emmetropia, myopia (nearsightedness), hyperopia (farsightedness), or astigmatism.
Unlike traditional retinoscopy, which requires a darkened room, the XO Exam ABT unit is light-tight, allowing the test to be conducted more efficiently in any part of the office environment.
XO Exam ABT also allows retinoscopy to be performed by the patient directly, providing feedback using the XO Remote or administered by a trained technician for those who may need assistance, such as very young and elderly patients.
