Suoer SW-6000

Ophthalmology clinics, optometry practices and contact lens fitting rooms use the SW-6000 to examine the shape of the cornea. Ophthalmologists, optometrists and ophthalmic technicians operate it, and the results inform screening for keratoconus, the fitting of contact lenses and the reading of curvature and elevation before and after treatment.

The SW-6000 suits services whose list is made up of corneal shape questions. A Placido disc of 31 rings gives 7,936 measuring points over a corneal coverage of 10.91 mm, and the radius of curvature is measured from 5.5 to 10.0 mm at a precision of ±0.02 mm. One capture therefore feeds axial curvature, tangential curvature, elevation, simulated keratoscope and 3D cornea maps.

Keratoconus detection and contact lens fitting work from the same data. The clinician can check the detection result against the curvature and elevation maps on one evaluation map view, and a fitting can be reviewed beside the corneal maps. Several examination view modes let the operator arrange the results to suit the question being asked. A contact lens practice can fit from the corneal data in the same visit, and a clinic reviewing a keratoconus finding can read curvature and elevation on the same screen.

The chinrest adjusts from 0 to 50 mm. The head of the instrument travels 0 to 86 mm left and right, 0 to 40 mm forward and back and 0 to 30 mm up and down, so patients of different sizes are aligned to the disc. A colour inkjet printer provides image output for the patient record, and the instrument sits on a stable table in a pre-test or consulting room.

Focus on corneal shape

The instrument concentrates on the cornea. Every function works from one Placido capture.

31-ring Placido disc

A disc of 31 rings gives 7,936 measuring points. They cover a corneal diameter of 10.91 mm.

Precision of ±0.02 mm

Radius of curvature is measured to ±0.02 mm. The range runs from 5.5 to 10.0 mm.

Five map types

Axial curvature, tangential curvature, elevation, simulated keratoscope and 3D cornea maps come from one capture. The operator does not repeat the examination for each view.

Keratoconus detection

A detection function is part of the software. It reads the same corneal data as the maps.

Contact lens fitting

A fitting function uses the Placido capture. The fitting is reviewed beside the corneal maps.

Evaluation map view

Findings are brought together in one view. Curvature, elevation and detection results are read side by side.

Wide positioning travel

The head travels 0 to 86 mm left and right, 0 to 40 mm forward and back and 0 to 30 mm up and down. Patients of different sizes are aligned to the disc.

Printed record

A colour inkjet printer provides image output. The printout goes into the patient record.

Placido disc

The disc has 31 rings. It is projected onto the cornea for each capture.

Measuring points

The capture gives 7,936 measuring points. All maps are built from them.

Corneal coverage

Coverage reaches a corneal diameter of 10.91 mm. The area is measured in one capture.

Radius range

Radius of curvature is measured from 5.5 to 10.0 mm. Precision is ±0.02 mm.

Axial curvature map

The map shows corneal curvature across the surface. It is read at a glance.

Tangential curvature map

The map shows local curvature across the cornea. It is produced from the same capture.

Elevation map

The map shows the height of the corneal surface. It supports screening and fitting work.

Simulated keratoscope

A simulated keratoscope view shows the ring pattern on the cornea. It is generated from the capture.

3D cornea map

A three-dimensional view of the cornea is produced. The operator reads the shape in one image.

Keratoconus detection

The detection function screens the corneal data. Its result is read with the maps.

Contact lens fitting

The fitting function plans a lens from the corneal data. It reuses the same capture.

Evaluation view

An evaluation map view gathers the findings. Several examination view modes are available.

Chinrest

The chinrest adjusts from 0 to 50 mm. It sets the patient height at the disc.

Positioning travel

Left and right travel is 0 to 86 mm, forward and back 0 to 40 mm and up and down 0 to 30 mm. The head moves to the eye.

Colour inkjet printer

A colour inkjet printer gives image output. It produces a record of each result.

The SW-6000 suits ophthalmology clinics, optometry practices and contact lens fitting rooms that want a topographer concentrated on corneal shape. A Placido disc of 31 rings, 7,936 measuring points and a radius range of 5.5 to 10.0 mm at ±0.02 mm precision feed axial curvature, tangential curvature, elevation, simulated keratoscope and 3D cornea maps from one capture. Keratoconus detection and contact lens fitting work from the same data and are read on one evaluation map view. A chinrest with 50 mm of travel and an instrument head with 86, 40 and 30 mm of travel position patients of different sizes, and a colour inkjet printer provides image output for the record. The SW-6000 covers a corneal diameter of 10.91 mm.
