CA-800

Corneal Analyzer

CA-800

Ease of use
The CA-800 is extremely easy to handle and use.
From image acquisition to analysis, the on-board
software is intuitive and user-friendly and the10.1-inch capacitive touch screen provides quick
navigation. Visual guidance supports fast andeasy alignment and focusing on the eye; the“best image” selection mode automaticallyacquires the best-focused image. The CA-800
is a placido-based topography system thatdelivers accurate, high resolution images of theanterior corneal surface. The keratoscope conewith 24 rings equally spaced on a 43D sphere
analyses over 100.000 data points, with axial
and instantaneous curvature evaluation.

Integrated PC
The brand new compact design of the CA-800
includes a fully integrated PC, so that an external
PC is not required to manage a patient databasefor archiving and re-analysis purposes. The
patient database is stored on an internal 320Gb
SATA hard disk and the CA-800 includes a 32Gb
SSD for a quick startup of the instrument anduser interface.

CA-800 Corneal Analyzer

Acquisition
The CA-800 is easy to use. Visual signals support
fast and easy alignment and focusing on the patientseye. The CA-800 has a Right and Left eye detection
and prevents incorrect savings in Right / Left eyemeasurements. The automated best image selection
mode in the software of the CA-800 decides the best
focused position and automatically acquires the image.
Acquistions can be made for topography, pupillometry
and real time fluorescein imaging.

Keratoconus screening
With the CA-800, signs of asymmetry of the cornea caneasily be detected even in an early stage. By analyzing
the apical curvature, apical gradient and symmetry of
the cornea, a Keratoconus probability index will showin color code (green, yellow & red) if the topography
is compatible with Keratoconus. With the CLMI (ConeLocation and Magnitude Index) it is easy to follow-up
on keratoconus and keratoconus-like patterns.

Corneal Zernike analysis
The Zernike analysis module consists of 36 polynomials
into the 7th order, and provides a clear view on the
optical deficiencies which can disturb vision. Basedon this information, the CA-800 provides the visualacuity summary. Zernike analysis is the basis for thecalculation of the ablation area for laser treatment.
The Zernike expansion coefficient is used to determine
which component(s) dominate the aberration structureof the cornea and to what degree.

Corneal comparison & differential map
With the CA-800, it is easy to compare topography
maps between two examinations of a patient, which canbe used for follow up and for pre- and post-operative
corneal analysis. With the differential map, progress inrecovery of the cornea can be observed after refractivesurgery. Parameters such as keratometry, apicalcurvature and corneal symmetry can be analyzed tofollow the development of any corneal surface changes.
The CA-800 comparison and differential maps help youwith the treatment of collagen cross linking to stop thedevelopment of corneal keratoconus.

Pupillometry
The CA-800 is equipped with two white LED’s for
dynamic and static pupillometry. With the CA-800
on-board, the user can check the pupil position anddiameter (from Photopic to Scotopic condition) in
relation to the position of the optical zone in Ortho-K,
laser treatment or refractive surgery treatments. Dynamic
pupillometry provides clear information on the reaction
time of the pupil and the contraction of the pupil.

Fluorometry
The CA-800 incorporates eight blue LED’s for fluorescein
images and real time fluorescein videos which are essential
for contact lens fitting. During every measurement, theCA-800 automatically registers the pupil diameter, whichis critical information during contact lens fitting. Real time
fluorescein films allow the eye care practitioner to judge themovement of the contact lens on the cornea, the distributionof the tear film under the contact lens as well as the wettingof the outer contact lens surface. The corneal condition canbe observed by recording a real time fluo film without wearing
a contact lens. The tear film condition, corneal artifacts andbreak up tear time (BUT) can be observed.

Meibomian gland analysis
With the Infra-red illumination of the CA-800, theMeibomian Glands of the upper and lower eyelid can be
captured and analyzed. Posterior blepharitis is the mostcommon form of lid margin disease. MGD (MeibomianGland Dysfunction) can cause or exacerbate dry eye
symptoms and eyelid inflammation. The oil glands
become blocked with thickened secretions. Chronicallyclogged glands eventually become unable to secrete
oil which results in permanent changes in the tear film
and dry eyes. With the CA-800, MGD can easily beobserved and compared with previous Meibomian glandexaminations of the patient.

Contact lens fitting simulation
The CA-800 provides the perfect platform for contact
lens fitting. Simulation software is provided on-board,which automatically selects the best fitting contact
lens based upon an included complete contact lens
database for all the main manufacturers (upgradableand customizable by the user). With the option to input
refractive powers, the contact lens proposal is accurate
and complete. The on-board fluorescein acquisition
system allows full control of the contact lens positionon the eye. The comparison between different contactlenses is easy in order to ensure the best fit.
