Description

  • UniSys Professional Visual Refraction System is a digital vision chart and refraction platform developed for ophthalmology, optometry, optical retail, and clinical refraction practices.
  • The system is designed to replace or upgrade conventional visual acuity drums and chart systems by offering a wide range of software-based test options on a digital display. The brochure positions UniSys as a professional visual refraction system with special emphasis on astigmatic correction and contrast sensitivity. One of the key features of UniSys is its astigmatic / cylindrical correction function, which supports cylindrical axis correction from 1° to 180° in 1° increments.
  • This helps practitioners determine cylindrical power more accurately and verify whether the patient is under-corrected, correctly corrected, or over-corrected. The system also includes an astigmatic fan / cylindrical test display for efficient astigmatic evaluation. The system includes contrast sensitivity testing with contrast levels of 50%, 25%, 12.5%, and 6.25%, making it useful for assessing reduced visual performance that may be associated with cataract, glaucoma, retinal problems, or other ocular defects. Contrast sensitivity can be tested across different optotypes and ETDRS formats, supporting more advanced clinical assessment beyond standard visual acuity. UniSys supports a broad range of optotypes and display modes, including English alphabets, numbers, alphanumeric charts, tumbling E, Landolt C, dots, HOVT, Allen symbols, geometric shapes, pediatric numbers, clock symbols, images, and Indian language optotypes.
  • The brochure mentions support for Indian languages including Hindi, Tamil, Kannada, Gujarati, Bengali, Punjabi, Telugu, and Urdu, making it suitable for diverse Indian clinical environments. The system also provides ETDRS chart display, randomised optotype display, 1-line display, 1-alphabet display, 3-line display, white-on-black mode, mirror mode, and red-green duochrome testing. The red-green duochrome test is useful for final spherical correction and helps avoid over-correction or under-correction.
  • The brochure mentions duochrome testing from 6/6 to 6/60 and availability across optotype display modes and ETDRS. UniSys further includes binocular and specialty test functions such as stereo testing for 3D depth perception using red-green goggles, colour vision testing, Worth 4 Dot, Schober test, and phoria-related functional tests. These features make it useful not only for routine refraction but also for basic binocular vision and functional visual assessment.
  • The system is suitable for small clinics because the refraction distance can be adjusted from 3 feet to 25 feet in 1-inch increments, allowing effective use even in limited space. It is operated through a remote control and includes a twin remote mode, allowing two UniSys units to be placed near each other without remote interference. The brochure also mentions USB image support, including surgical videos, patient education clips, and cartoon movies for pediatric patients. Overall, UniSys is a multifunctional digital refraction system that combines visual acuity testing, astigmatic correction, contrast sensitivity, ETDRS, duochrome, stereo, colour vision, pediatric charts, Indian language charts, and functional vision tests in one software-based platform.
TopicDiscription
Product NameUniSys Professional Visual Refraction System
Product OverviewUniSys is a professional digital visual refraction system designed for precise refraction, astigmatic correction, contrast sensitivity testing, red-green duochrome testing, stereo testing, colour vision testing, and functional binocular vision assessment. It provides software-based optotype display with multiple test modes, Indian language options, ETDRS support, and remote-controlled operation for modern refraction clinics.
Product Brief DetailThe UniSys system combines multiple refraction and vision testing functions into a digital chart platform. It supports standard optotypes, ETDRS display, contrast sensitivity variation, cylindrical correction tests, randomised optotype display, stereo tests using red-green goggles, colour vision tests, and functional tests such as Worth 4 Dot, Schober, and phoria testing. The system is suitable for compact refraction rooms because the viewing distance can be set from 3 ft to 25 ft in 1-inch increments.
