Visionstar KR-9600

Corneal Curvature and Power

Curvature radius covers 5 to 10mm in 0.01mm steps and corneal refractive power 33.75 to 67.50D in 0.12 or 0.25D steps across the whole measuring range.

Corneal Astigmatism to Fifteen Dioptres

Cylindrical power extends from 0.00 to 15.00D in 0.12 or 0.25 steps, with corneal axis across 0 to 180 degrees in 1 degree steps on the instrument.

Corneal Diameter

Corneal diameter is measured from 2.0 to 12.00mm, giving a figure that a fitting or a screening assessment ordinarily requires alongside the curvature.

Automatic Position Identification

The best measurement position for keratometry is identified automatically, which the manufacturer relates to avoiding operating error and accurate keratometry.

Three Measurement Modes

Combined refraction and keratometry, refraction alone, or keratometry alone are each selectable, so an operator runs only what a particular patient requires.

Full Refraction Range

Sphere covers minus 25.00 to plus 22.00D at a vertex distance of 12mm and cylinder 0.00 to plus or minus 10.00D, with pupil distance from 10 to 85mm.

IOL Function and Pupil Size

An intraocular lens function is available, minimum measurable pupil diameter is 2.0mm, and pupil size is measured and reported as a figure in its own right.

Screen, Chin Rest and Output

A 7 inch touch screen adjusts through 90 degrees, the chin rest is motorised, and output covers RS232, a wireless connection and a thermal printer with auto cutter.

Rigid and Toric Contact Lens Fitting

This is the case the keratometry exists for. A rigid lens is fitted to the corneal curvature, and a toric lens selection depends on corneal astigmatism, so radius to 0.01mm and cylindrical power to 15.00D are the figures a fitting is actually built on. A practice doing this work regularly cannot use a refraction only instrument without measuring the cornea separately on some other machine, which costs both time and a second set of records.

Corneal Assessment and Screening Support

Curvature radius, corneal power, astigmatism and the diameter together describe the shape of a cornea rather than merely its optical result. For a practice watching a suspicious cornea over time, or deciding whether a referral is warranted, the recorded figures across successive visits are what turn an impression into something a colleague can actually act upon later, and not merely a note of an impression.

Post Cataract and Implanted Eyes

The IOL function provides a dedicated setting for any eye with an implanted lens, which does not behave optically as a natural crystalline lens does. Taken together with corneal measurement in the same sitting, that suits a practice seeing patients after surgery who need both their refraction and their corneal figures recorded together at one visit.

Busy Practices Wanting One Instrument

Three selectable modes mean that the very same unit serves a routine sight test, a contact lens appointment and a corneal check without anything being swapped. For a practice with one consulting room, or one instrument shared across several rooms, that consolidation is worth rather more than any individual figure on the specification sheet.

Both Measurements in One Sitting

Refraction and keratometry from a single instrument, selectable by mode, mean that a patient is measured once rather than being moved between machines. For contact lens work in particular, where both figures are needed before a lens can be chosen at all, that saves appointment time and removes the risk of one set of figures being recorded and the other quietly forgotten about until the fitting itself arrives.

Alignment the Instrument Finds

Corneal readings are far more sensitive to alignment than refraction is, and automatic identification of the best measuring position addresses exactly that. The manufacturer relates it to avoiding operating error. In practice it means a corneal figure taken by a trainee ought to be comparable with one taken by a senior colleague, which is what makes a recorded series of figures worth anything at all.

Range Across Both Measurements

Corneal astigmatism to 15.00D and sphere from minus 25.00 to plus 22.00D are both wide, and range is what decides whether an instrument can measure a given patient. The corneas and prescriptions that fall outside a narrower instrument are precisely the ones most worth measuring properly, so a wider span converts directly into fewer patients being sent elsewhere merely to obtain the figures that a practice ought to be able to take itself.

The Visionstar KR-9600 measures corneal curvature radius from 5 to 10mm in 0.01mm steps, corneal refractive power from 33.75 to 67.50D, cylindrical power from 0.00 to 15.00D, corneal axis across 0 to 180 degrees and corneal diameter from 2.0 to 12.00mm. Refraction covers sphere from minus 25.00 to plus 22.00D at a vertex distance of 12mm and cylinder to 10.00D, with pupil distance from 10 to 85mm, a minimum measurable pupil of 2.0mm and separate pupil size measurement. Three measurement modes, automatic position identification, an IOL function, auto tracking, a 7 inch screen adjusting through 90 degrees, a motorised chin rest, RS232 and wireless output and a thermal printer are all fitted. The instrument measures 262 by 487 by 467mm and weighs 17.5kg.
