Anterior Segment OCT MS-39

The MS-39 is the most advanced corneal map device using a AS-OCT and Placido disk corneal topography to obtain measurements of the anterior segment of the eye. In addition to anterior segment clinical diagnostics,MS-39 can be used in corneal surgery for refractive surgery planning.

Peripheral Evaluation

MS-39 can measure and detect on the Placido image so that height, slope, and curvature data can be calculated using the arc-step method with conic curves. Profiles of the anterior cornea, posterior cornea, anterior lens, and iris are derived from the AS-OCT scans.

• Tangential curvature (anterior and posterior)
• Sagittal curvature (anterior and posterior)
• Elevation (anterior and posterior)
• Refractive power (equivalent, anterior and posterior)
• Corneal thickness
• Epithelial thickness
• Anterior chamber depth

Analysis and Detection

MS-39 captures footage with the advanced manual acquisition and electronically guided control joystick, which guarantees high precision and repeatability of all measurements.

 

Data for the anterior surface from the Placido image and SD-OCT scans are merged using a proprietary method. All other measurements for internal structures (posterior cornea, anterior lens, and iris) are derived solely from SD-OCT data.

Electromedical System

Phoenix Software

The MS-39 works perfectly with the advanced PHOENIX software. This program enables comfortable working, by connecting all of your diagnostic instruments with a powerful patient database, giving you an extraordinarily effective work station.

Crystalline Biometry

Lenticular crystalline biometry on non cataractous lenses has been studied by means of Scheimpflug photography and digital image analysis. MS-39 provides a capture mode to measure the crystalline lens thickness, its distance from the cornea and its equator.

Keratoconous

Screening

Keratoconous screening provides the
clinician with important information about
the patients cornea. Understanding this
can help prevent complications associated
with ectasia before corneal surgery is
undertaken.

Glaucoma Screening

The MS-39 device allows the glaucoma screening and gives the measurement of irido-corneal angles AOD, TISA and corneal pachymetry. These values are useful to diagnose the eyes optic nerve and intraocular pressures to detect any diseases which can

be due to the conformation of the anterior chamber.

Pupillography

Sirius has built-in pupillography measurement
soft ware. The measurement of the pupil in
scotopic (0.04 lux), mesopic (4 lux), photopic
(50 lux) conditions and in dynamic mode.
Knowing the center and the diameter of the
pupil, is essential for many clinical procedures
which seek to optimize vision  quality. 

Advanced Analysis of the Tear Film

Placido disk technology allows for the
advanced analysis of the tear film such as:

  • Tear film examination with white light

  • Tear film examination with fluorescein

  • Break-up time measurement

  • Examination of tear layers

  • Examination of rigid LAC clearance with fluorescein

Intrastromal Rings

On the basis of the pachymetry map and
corneal alti - metric data, SIRIUS allows for
intrastromal rings system planning, which
maybe an option for the correction of
refractive defects and some forms of
keratoconus.

Corneal Aberrometry

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) can help the clinician in understanding or explaining the patient’s visual problems.

IOL Calculation Module (Optional)

This module is based on Ray-Tracing techniques, regardless of the state of the cornea (untreated or previously treated for refractive purposes), provides the calculation of the spherical and
toric power of the intraocular lens.

Ephithelial Map

Epithelial thickness mapping can help us identify early keratoconus while screening patients for corneal refractive surgery. Epithelial thickness mapping provides additional supporting evidence in the diagnosis, which allows us to offer alternative treatment options.
