WaveFront Sciences presents the COAS-HD Model 2800 high-definition precision aberrometer. The Model 2800 (2800 is the number of samples in a 9.5-mm pupil) extends the capability of wavefront-based ophthalmic metrology and provides the physician with an ultra-detailed map of the eye.

The newest member of the Complete Ophthalmic Analysis System (COAS) family of precision aberrometers is based on Shack-Hartmann wavefront-sensing technology to provide unparalleled accuracy, range, and resolution for ophthalmic research, according to the company.

The aberrometer's wavefront maps are reconstructed directly from the sensor array without mathematical interpolations or smoothing. In addition, the device provides 25th-order Zernike reconstructions and has sufficient resolution to provide on-screen displays of striae, corneal scarring, flap folds, cataracts, incipient keratoconus, and advanced keratoconus.

The device characterizes up to 10 D of astigmatism throughout the spherical range of 7 to -15 D. Pupil diameters as large as 9.5 mm are measurable. The combination of large pupil diameter and cylinder range means all patients can be measured with the device.
