The Rexam AR, Kerato & Topographer, REF TOPO RET-700  is an advanced auto refractometer keratometer and corneal topographer designed for ophthalmology clinics, eye hospitals, optometry practices and professional eye-care facilities by Mediscience. By combining objective refraction, keratometry and corneal topography in a single platform, the RET-700 provides a comprehensive solution for anterior-eye examination and corneal assessment.

The Rexam RET-700 is designed as an all-in-one ophthalmic diagnostic system, integrating the functions of an autorefractometer, keratometer and corneal topographer, together with a built-in PC and database. This integrated configuration can help B2B eye-care facilities consolidate multiple diagnostic functions into a single examination unit.

As a professional corneal topographer, the RET-700 provides a measurement range of approximately 0.4–10.7 mm (R8.0) and can assess the peripheral cornea over an area of approximately 16 mm. Its Placido-dome system uses 19 concentric circular ring patterns for corneal-shape measurement, supporting detailed corneal mapping and analysis.

The Rexam AR, Kerato & Topographer, REF TOPO RET-700 also performs objective refractive measurements. Its spherical measurement range is -20D to +30D, while cylindrical power can be measured from 0D to ±10D. Axis measurement covers 1–180°, providing a broad measurement range for routine refractive assessment.

For corneal evaluation, the Rexam RET-700 measures corneal curvature radius from 4.90 mm to 10.10 mm, with a 0.01 mm measurement step. Corneal refractive power ranges from 68.88D to 33.42D, while corneal astigmatism can be measured from 0D to ±10D.

A major advantage of the Rexam RET-700 is its range of corneal analysis functions. The system supports axial, tangential, elevation and refractive mapping, along with Zernike and Fourier analysis. Analysis options include current maps, multiple maps, dual-case comparisons, difference maps, aberration analysis and contact-lens fitting.

The system can capture up to six topography images continuously, while its ring-edit function allows the operator to manually assign a ring when automatic measurement is unsuccessful. This provides additional flexibility when performing corneal topography in clinical settings.

The Rexam AR, Kerato & Topographer, REF TOPO RET-700 also includes pupil-diameter measurement from 2.0 mm to 8.5 mm, with the ability to perform both scotopic and photopic pupil measurements. This can provide additional information for clinical assessment where pupil size under different illumination conditions is relevant.

For contact-lens professionals, the Rexam RET-700 includes contact-lens fitting functionality, allowing corneal topography information to support lens-selection and fitting workflows. Optional functionality for dry-eye observation and meibomian gland analysis is also available according to current product documentation.

The device incorporates a 10.4-inch colour touchscreen display, built-in PC and database, thermal printer and external connectivity through USB-A, USB-B and Ethernet. Its built-in computer and database allow measurement data to be stored and accessed for clinical workflow and record management.

For B2B procurement, the Rexam AR, Kerato & Topographer, REF TOPO RET-700 is therefore suited to ophthalmology departments, eye hospitals, optometry practices, contact-lens clinics and diagnostic centres requiring an integrated platform for refraction, keratometry and corneal topography.
