MS-39 is a device capable of analyzing the entire anterior segment of the eye. It has several systems inside: Scheimplug, Placido’s disc, OCT of the anterior segment. The fields of application of the instrument therefore is several, from advanced diagnostics of the anterior segment, for refractive surgery using excimer laser and femto second laser, to intraocular IOL implantation, up to the insertion of intrastromal rings for some forms of keratoconus.
MS-39 includes advanced epithelial map measurement. The epithelial masking effect is known, so the knowledge of its morphology is very useful for evaluating the alterations of the corneal surface.
The aberrometric analysis offers a complete overview of corneal aberrations. It is possible to select the anterior, posterior or total corneal contribution for different pupil diameters. The OPD / WFE map and visual simulations (PSF, MTF, image convolution) can help the clinician in understanding or explaining the patient’s visual discomfort.
FEATURES OF THE PHOENIX SOFTWARE
The Phoenix user software interface is a multi-device platform capable of simultaneously integrating all CSO products. It is possible to share the patient archive with other devices.
An effective, clinically validated keratoconus screening system, based on a self-learning system, provides suggestions on the risks of ectasia, highlighting cases in which the probability of complications is greater.
Completely integrated with the topography of the anterior surface of the cornea, it measures the pupil in scotopic (0.04 lux), mesopic (4 lux), photopic (50 lux) conditions and in dynamic mode. Knowledge of the center and pupil diameter is essential for all clinical procedures aimed at optimizing the quality of vision.
In order to determine the ELED more accurately, and consequently refine the calculation of intraocular lenses, the device provides an acquisition mode suitable for measuring the thickness of the lens, its distance from the cornea and its equator.
IOL CALCULATION MODULE
The module is based on Ray-Tracing techniques which, regardless of the state of the cornea (virgin or previously treated for refractive purposes), provides the calculation of the spherical and toric power of the intraocular lens.
Based on the pachymetric map and corneal altimetric data, MS-39 allows the planning of the implantation of intrastromal rings, which can constitute a surgical solution for the correction of refractive defects and some forms of keratoconus.
ADVANCED LACRIMAL FILM ANALYSIS
Thanks to Placido’s disc, the MS-39 device allows advanced analysis of the tear film and to evaluate its NI-BUT (Non Invasive Break-up Time).
For glaucoma specialists, the device provides AOD and TISA index measurement and corneal pachymetry. These values are used in the most common IOP correction formulas that help diagnose the disease if it is due to the conformation of the anterior chamber.
The diagnostic tests that the MS-39 can provide are the following:
- CORNEAL TOPOGRAPHY: studies the elevation, curvature and power of the anterior and posterior face of the cornea and its thickness (pachymetry).
- KERATOCONUS SCREENING: it contains validated clinical data that allow to evaluate the possible risks of ectasia of the corneal surface.
- CORNEAL ABERROMETRY: allows an aberrometric analysis of both the anterior and posterior corneal surfaces, individually or total, in the different pupillary diameters.
- EPITHELIAL MAP: highlights the morphology of the epithelium, in this way, its use is useful for evaluating any alterations of the corneal surface.
- PUPILLOGRAPHY: it is able to measure the pupil diameter in different light conditions, scotopic (dark), mesopic (medium light), photopic (full light), and in dynamic mode.
- ADVANCED ANALYSIS OF THE TEAR FILM: using the Placido’s disc, it allows an advanced analysis of the tear film and to evaluate the NI-BUT (Non Invasive Break-Up Time), that is the break time of the tear film.
- OCT OF THE ANTERIOR SEGMENT: the coherent radiation optical tomography performs a high resolution analysis of the anterior portion of the eye, in all its parts: cornea, iris, chamber angle, crystalline lens, highlighting any anomalies.
- INTRASTROMAL RINGS: once the pachymetric data and corneal curvatures have been acquired, through a specific program, it is possible to simulate and plan the implantation of intrastromal rings.
- GLAUCOMA SCREENING: the OCT of the anterior segment, together with the corneal pachymetry, provides the measure of the indices to diagnose any alteration of the internal ocular pressure (IOP) due to the conformation of the anterior chamber.
- CRYSTALLINE BIOMETRY: it is able to measure the thickness of the lens, its distance from the cornea, and its equator, to make the calculation of intraocular lenses more precise.
- IOL CALCULATION MODULE: it is based on Ray-Tracing techniques, which are independent of the state of the cornea, and therefore are not influenced or modified in their calculations by any previous corneal interventions (e.g. refractive surgery, radial keratotomies, etc.), provides the calculation of spherical and toric IOL.
