The sharpness of the high-resolution section images on a diameter of 16 mm, together with the many details of the structure and the cornea layers brought to light by the instrument, are the most extraordinary features and appreciated by the specialists of the anterior segment (corneal and epithelial) . The device provides pachymetry, elevation, curvature and power information for both corneal surfaces.
EPITHELIAL AND STROMAL MAP
MS-39 includes the advanced measurement of the epithelial and stromal layer. The epithelial masking effect is known, so knowledge of its morphology is very useful assess abnormalities of the corneal surface.
Aberrometric analysis offers a complete overview of the corneal aberrations. It is possible to select the contribution of the anterior, posterior or total cornea for different pupil diameters. The OPD/WFE maps and the visual simulations (PSF, MTF, image convolution) can help the clinicain in understanding or explaining the patient’s visual problems.
Keratoconous screening provides the clinician with important information about the patinets cornea. Understanding this can help prevent complications associated with ectasia before corneal surgery is undertaken.
In order to more accurately determine the ELED, and consequently to reﬁne the intra-ocular lens calculation, MS-39 provides an acquisition mode to measure the crystalline lens thickness, its distance from the cornea and its equator.
