Profile: AMO Wavefront Sciences LLC specializes in providing highly sensitive optical measurement systems to ophthalmic surgeons with detailed measurements for Lasik surgery. COAS-HDTM Model 2800 is a high definition wavefront aberrometer. The Model 2800 (2800 is the number of samples in a 9.5mm pupil) extends the capability of wavefront-based ophthalmic metrology and gives the physician an ultra-detailed map of the eye. The 2800's wavefront maps are reconstructed directly from the sensor array without mathematical interpolations or smoothing. The 2800 accurately characterizes up to 10 diopters of astigmatism throughout the spherical range of +7 to -15 diopters. Pupil diameters as large as 9.5mm are measureable. The combination of large pupil diameter and cylinder range means the 2800 can easily measure patients. The 2800 can measure all patients.
