KONOSCREEN Corneal Topographer

Description The Konoscreen Topographer with Eye Top 2005 software, combines the latest technological advances in the field of corneal topography. Its sophisticated features, its compact and ergonomic design, its utter reliability and simple method of use place it at the top of instruments used for diagnostics, contactology and refractive surgery.

The instrument comes with a base and work surface and is particularly suited to those cases where "less clutter" plays an important part in the choice of examination room instrument.

Eye Top 2005

The Eye Top 2005 software has been designed for those coming to corneal topography for the first time.
Software features:
• An auto-focus algorithm helps you capture measurements in sequence and at the correct distances from the disc
• An advanced ring editing system lets you modify their edge positions in order to guarantee a correct reconstruction - even for particularly distorted corneal surfaces
ï Mapping the axial curvature
• Instantaneous curvature mapping allowing immediate measurement of the corneal surface morphology
• Ability to set Absolute, Normalised and Adjustable scales for general or detailed visualisation of every map
• Ability to measure ñ in millimetres or dioptres ñ the curve measurement or to  express eccentricity  in p, e, Q or SF
• Instruments for follow-up visits, such as:
• Ability to compare up to 4 different instantaneous curvature maps, axial curvature maps or refractive power maps
• A wide range of synthetic descriptors for cornea properties, such as:
- Sim K to simulate the measurements of an ophthalmoscope at fixed targets
- Meridians with larger corneal cylinder in the 3 mm, 5 mm and 7 mm zones
- Flatter and more curved hemimeridians in the 3 mm, 5 mm and 7 mm zones
- Pupil decentring, pupil radius and size of the corneal diameter
• Import and export of data to exchange case history details

An add-on module can be chosen, with the following functions:
• Refractive power mapping
• Altimetry mapping
• Differential mapping
• "Vinciguerra" curvature gradient map
• "Vinciguerra" cataract summary
• Complete pupillometry integrated with the topography, lets you:
- Measure the dynamic pupillometry, starting at more than 400 lux and switching off the light source in order to allow the pupil to dilate to its maximum extension
- Assess pupil decentring in respect of the vertex and the drift of the pupil centre during dilation
- Visualise the pupil on the topographic map
• Corneal wave front analysis including:
- Corneal wave front  summary with the ability to set pupil parameters
- Visual quality summary with information on PSF, Spot Diagrams and MTF for the wavefront examined
• Orthokeratology
