VisionStar SP-1000

Three Post-Refractive Formulas

Latkany Myopic, Latkany Hyperopic and Double-K SRK-T address eyes altered by earlier corneal refractive surgery, where standard formulas cannot be relied upon. These eyes are now reaching cataract age in substantial numbers.

Six Conventional Lens Formulas

SRK-II, SRK-T, Binkhorst II, Holladay, Hoffer-Q and Haigis cover untreated eyes, letting a surgeon apply whichever formula suits the axial length in front of them.

Six Eye Modes Including Custom

Normal phakic, normal cataract, dense cataract, aphakic and pseudophakic settings are joined by a customer defined mode for departments with particular requirements.

Three Measurement Methods

Automatic handheld, chin rest mounted and manual foot switch operation are all available, so technique follows the patient and the clinician rather than the instrument. Contact and immersion techniques are both supported alongside.

Wide Axial Length Range

Measurement spans 14.0 to 46.0 millimetres of axial length, with anterior chamber depth from 2.0 to 6.0 and lens thickness from 2.0 to 7.5 millimetres.

Resolution to 0.01 Millimetres

Accuracy is 0.1 millimetres with resolution of 0.01 millimetres, using a 10MHz solid state probe carrying a built-in fixation light to steady the patient's gaze.

20MHz Corneal Measurement

The pachymetry probe covers 125 to 1000 microns with accuracy of plus or minus 10 microns and resolution of plus or minus 1 micron.

Compact Body With Touchscreen

A light, compact housing with a 5.6 inch LCD touchscreen suits clinics where bench space is limited, with a thermal printer and computer connection built in.

Cataract Surgery After Laser Vision Correction

This is the situation the instrument is built for. Corneal refractive surgery changes the anterior corneal curvature without changing the posterior surface in the same way, which breaks the assumption standard lens formulas depend on and leads to refractive surprises after cataract surgery. Providing Latkany Myopic, Latkany Hyperopic and Double-K SRK-T gives the surgeon calculation methods developed specifically for those eyes. Identifying such a history before measuring is therefore essential to the calculation.

Routine Cataract Assessment

For untreated eyes, six established formulas and six eye modes cover ordinary practice thoroughly. Axial length across 14.0 to 46.0 millimetres accommodates both very short and very long eyes, which is where formula choice matters most, and anterior chamber depth and lens thickness are reported alongside to feed the calculations that require them. Selecting the appropriate eye mode before measuring supports reliable results.

Corneal Assessment and Glaucoma Clinics

Corneal thickness across 125 to 1000 microns with resolution to a single micron supports assessment where corneal measurement informs interpretation of pressure readings. Having both examinations in one compact unit means a clinic running mixed lists does not need separate instruments occupying separate positions. One position on the bench therefore covers both examinations.

Space-Limited and Mobile Clinics

The compact, lightweight body with a 5.6 inch touchscreen suits rooms where a larger console would not fit, and automatic handheld measurement means the instrument does not require the patient to be positioned at a chin rest. Computer connection and an optional workstation extend record keeping where a clinic wants it. Setting up in a new room takes very little time or effort.

Ready for the Post-Refractive Generation

The population who had laser correction in the nineteen nineties and two thousands is now developing cataracts in significant numbers, and these eyes are the ones most likely to produce a disappointing refractive outcome if calculated conventionally. An instrument carrying dedicated formulas for them is not an optional refinement but a practical requirement for any service expecting to see such patients regularly. Getting the calculation right the first time avoids a second procedure. Expectations among these patients also tend to be high, since they chose surgery once already.

Technique Follows the Patient

Automatic handheld, chin rest and foot switch operation cover situations that differ considerably. A cooperative patient at a chin rest, a child or a person unable to sit upright, and a clinician wanting deliberate manual control each need something different, and one instrument supporting all three avoids compromise. Flexibility of this kind widens who a service can measure comfortably. Nobody has to be turned away because positioning proves impossible.

Complete Workflow in a Small Footprint

Biometry, pachymetry, calculation, automatic data retrieval, printing and computer connection all sit in a compact body with a 5.6 inch touchscreen. Clinics with limited bench space gain a full pre-operative workup at one position, and results reach the record without transcription. Automatic retrieval of earlier readings supports comparison across visits without manual searching.

The SP-1000 answers a question that will only become more pressing: how to plan cataract surgery accurately in eyes that have already been altered by laser vision correction. Latkany Myopic, Latkany Hyperopic and Double-K SRK-T sit alongside six conventional formulas, so a surgeon has appropriate calculation methods whether the cornea is untouched or previously treated.

Measurement is thorough. A 10MHz solid state probe with built-in fixation light covers axial length from 14.0 to 46.0 millimetres to 0.01 millimetre resolution, with anterior chamber depth and lens thickness reported alongside, and a 20MHz probe measures corneal thickness across 125 to 1000 microns to a single micron.

Six eye modes including a customer defined setting, three measurement methods spanning handheld, chin rest and foot switch, contact and immersion technique, automatic data retrieval, a thermal printer and computer connection complete the instrument, all within a compact body driven from a 5.6 inch touchscreen.

The compact body suits clinics where bench space is genuinely scarce. Three configurations are offered. Medigear.uk supplies the SP-1000 as a verified medical equipment supplier and will confirm which configuration applies, along with probe content, workstation options, software, mains arrangement, condition and accessory content.
