Visionstar PE-03

Ultrasonic Emulsification at 40kHz

The ultrasonic frequency is listed at 40kHz, with digital frequency tracing described as managing the emulsification process smoothly.

Four Functional Modes

Continuance, pulse, linear and burst are all listed. Pulse offers a frequency range of 1 to 99Hz and linear puts power under footswitch control from 0 to 100 per cent.

Burst Timing Control

Burst stopping time is listed from 1.5 to 0s and burst working time from 5 to 100ms, giving control over how energy is delivered in that mode.

Peristaltic Aspiration

Vacuum is adjustable from 0 to 500 mmHg with a maximum of 500 mmHg, flux rate from 0 to 40 ml/min with a maximum of 40 ml/min, and reflux at 20 ml/min.

Built In Vitrectomy

The vitrectomy function is driven by an air pump with maximum vacuum of 500 mmHg and a listed rate of 20 to 600 per minute in steps of 10 per minute.

Bipolar Cautery

Cautery is bipolar with maximum power of 10 W plus or minus 20 per cent into 200 ohms, presettable anywhere between 0 and 100 per cent.

Touch Screen and Presets

A large TFT touch screen carries the functional menu, with up to ten sets of parameters stored for different requirements and a voice reminder alongside.

Automatic Test Function

An automatic test checks the tubing and the handpiece for problems such as blockage or leakage, with the whole system monitored by microprocessor.

Ultrasonic Lens Emulsification

The core function is ultrasonic emulsification at 40kHz, with four modes giving the surgeon different ways of applying energy. Continuance provides steady power across a 0 to 100 range, pulse works at 1 to 99Hz, linear hands proportional control to the footswitch, and burst is defined by its stopping and working times. Which mode and which settings suit a given case is entirely a surgical judgement and lies outside what a product listing should advise.

Irrigation and Aspiration

Peristaltic pumps govern the fluidics, with vacuum adjustable to 500 mmHg and flux rate to 40 ml/min. The manufacturer relates this arrangement to complete control of aspiration flow rate and to stronger suction during irrigation and aspiration, together with freedom from anterior chamber shallowing. Those are the manufacturer's own characterisations of the design rather than independent findings, and a dedicated handpiece is supplied within the standard configuration.

Anterior Vitrectomy

An air driven vitrectomy function is built into the same console, with maximum vacuum of 500 mmHg and its own tip and irrigation sleeve in the standard configuration. Having vitrectomy available on the console already in use means a team is not dependent on a second machine being present and set up when the need for it arises during a case.

Bipolar Haemostasis

Bipolar cautery with forceps and cable is included, at a maximum of 10 W plus or minus 20 per cent into 200 ohms and presettable across the full range. Keeping cautery on the same console removes another separate unit from a crowded theatre and puts its power setting on the same screen as everything else the surgeon is controlling.

Three Functions, One Footprint

Emulsification, vitrectomy and bipolar cautery on a single console removes two separate machines from a theatre and consolidates their controls onto one touch screen. For a unit with limited floor space, or one setting up a room used for more than one kind of list, that consolidation matters practically. It also means one set of controls to learn and one machine to power up, prepare and check before a session begins.

Fluidics Under Deliberate Control

Peristaltic pumping with vacuum adjustable across 0 to 500 mmHg and flux rate across 0 to 40 ml/min gives the surgeon a wide and continuous range rather than a handful of fixed settings. The manufacturer connects this to aspiration control and chamber stability. Whatever weight a team gives those claims, the underlying figures are stated and can be compared directly against whatever the unit uses at present.

Preparation Handled by the Console

An automatic test for tubing blockage and handpiece leakage means a fault is found during setup rather than discovered mid case, and ten parameter presets let a unit store the arrangements its surgeons actually use instead of rebuilding them each morning. Microprocessor monitoring across the whole system and a voice reminder support the same end, which is fewer surprises once a list has started.

The Visionstar PE-03 brings ultrasonic emulsification, anterior vitrectomy and bipolar cautery onto one console. Emulsification runs at 40kHz across continuance, pulse, linear and burst modes, with pulse frequency from 1 to 99Hz, linear power under footswitch control and burst timing defined between 1.5 and 0s stopping and 5 to 100ms working. Peristaltic fluidics offer vacuum from 0 to 500 mmHg and flux from 0 to 40 ml/min, the air driven vitrectomy reaches 500 mmHg, and bipolar cautery delivers up to 10 W plus or minus 20 per cent into 200 ohms. Thirteen items are listed in the standard configuration.

This page states what the technical data states. Electrical supply, dimensions, mass, consumable availability, service requirements, configuration and condition do not appear on the material held. The characterisations regarding aspiration control and anterior chamber stability are the manufacturer's own. Nothing here should be read as a claim about testing or regulatory approval, and a console of this kind is intended for appropriately trained surgical teams.
