2.3 INTENDED USE
MS-39 AS-OCT is a medical device used in the ophthalmological
diagnosis to perform the analysis of the anterior segment of the eye. In
a single structure, it combines corneal topography with Placido’s disk
and OCT-based anterior segment tomography.
The device has been designed for the screening, the capture and the
processing of 25 clear sectional images, in high resolution over a
diameter of 16 mm.
The device provides pachymetry data, elevation, curvature and power
information of both corneal surfaces.
Additional satellite exams allow an accurate pupil diameter
measurement in scotopic, mesopic, photopic conditions and in
dynamic mode and their integration with corneal map.
On the basis of the pachymetry map and corneal elevation data, the
device allows the intrastromal rings system planning, for the
correction of refractive defects and some forms of keratoconus.
The device allows the glaucoma screening and gives the measurement
of irido-corneal angles and pachymetry. These values, and the most
common IOP correction formulas are useful to diagnose some diseases
which can be due to the conformation of the anterior chamber.
Corneal topography and tomography of the anterior segment
The device provides information on pachymetry, elevation, curvature
and dioptric power of both corneal surfaces over a diameter of 10 mm.
All biometric measurements of the anterior chamber are calculated
starting from 25 sections from the cornea over a diameter of 16 mm.
In addition to the clinical diagnostic, the most common fields of
application are the refractive and cataract surgery.

13/52
Pupillography
The pupillography module is completely integrated with the
topography and allows to:
- Perform the pupillometry measurement in scotopic light condition
in order to evaluate the maximal pupil extension and the optic
zone dimension that has to be set for a treatment.
- Perform the pupillometry measurement in scotopic light condition
(0.04 lux).
- Perform the pupillometry measurement in mesopic light condition
(4 lux).
- Perform the pupillometry measurement in photopic light condition
(50 lux).
- Perform the dynamic pupillometry measurement, starting form
400 lux and turning off the luminous source so that the pupil
dilates to its maximal extension.
- Evaluate the pupillary decentralization with respect to the corneal
vertex for each of the conditions described above and the pupillary
centre deviation during the dilatation.
Analysis of the tear film
The Placido's disk allows the advanced analysis of the tear film and the
evaluation of the NI-BUT (Non-Invasive Break-up Time).
IOL calculation module
It is available an IOL calculation module based on Ray-Tracing
techniques which, regardless of the clinical status of the cornea,
provides the values of the spherical and toric power of the intraocular
lens. This allows the planning of the corneal surgery for refractive
defects, either photoablative and by means of intraocular lens
implants.

Corneal aberrometry
The device allows to perform the analysis of the corneal aberrometry.
It is possible to select the anterior, posterior or total corneal
contribution for different diameters of the pupil. The OPD/WFE map
and the visual simulations (PSF, MTF and image convolution) can help
understanding and explaining the patient’s visual discomfort.
Biometry of the crystalline
In order to more accurately determine the ELEP, and consequently to
refine the intra-ocular lens calculation, the device provides a capture
mode to measure the crystalline lens thickness, its distance from the
cornea and its equator.
Glaucoma screening
The device allows the glaucoma screening and gives the measurement
of irido-corneal angles AOD, TISA and corneal pachymetry. These
values, and the most common IOP correction formulas are useful to
diagnose some diseases which can be due to the conformation of the
anterior chamber.
Keratoconus screening
An efficient keratoconus screening system, clinically validated, based
on a self-learning system, provides suggestions on the risk underlining
the cases which have a greater possibility of complications.
Dry Eye Report
The Dry Eye Report provides a general evaluation of the patient’s
clinical conditions, aimed at diagnosing tear film dysfunctions. The
evaluation is based on:
- Ocular Surface Disease Index (OSDI)
- analysis of the redness of the eye
- Analysis of Meibomian glands
- Tear meniscus analysis
- NiBUT.
