Alcon OcuScan RxP

The OcuScan RxP serves ophthalmology clinics, eye hospitals, cataract surgery planning departments, and optometry practices that run on-site A-scan biometry. It reads axial length, lens thickness, anterior chamber depth,h and vitreous length in one measurement routine, and six IOL formulas convert the values into lens power for the planned implant. Velocity is programmable for each eye segment, and an age-compensation option adds age-related velocity compensation for natural lenses.

Ophthalmologists, optometrists, and ophthalmic technicians operate it, and the workflow keeps hands on the patient. A foot pedal gives hands-free control, Auto, Manual and Super Auto modes match the operator's preferred way of capturing a reading, and a beep sounds each time a reading is stored. Up to five user profiles store each surgeon's settings, with 10 editable IOL slots in each so that a rotating team can work from one console without resetting constants.

With the optional pachymetry software and probe, the same console records corneal thickness in single-point, mapped and LASIK modes. LASIK mode records three points in each of four phases, supporting measurements before and after a refractive procedure, and Single Point mode shows the minimum, average, standard deviation, and adjusted IOP.

At the end of a session, the built-in thermal printer prints the current screen or a full patient report, and a CompactFlash card carries patient data to a computer. The console weighs 4.85 kg, sits on a desk or mounts through four threaded holes in its base, and operates from 10 to 35 °C. A built-in contact eye model keeps probe testing at the bench between patients.

Hands on the patient through a foot pedal

The foot pedal gives hands-free control of the scan. Both hands stay on the probe and the patient, and the speaker beeps each time a reading is stored.

Three capture modes

Auto, Manual and Super Auto modes are available in both biometry and pachymetry. Each operator can choose the capture style that suits their technique, and Super Auto adds voice confirmation in pachymetry.

Six formulas on one console

Holladay, SRK II, SRK/T, Binkhorst II and Hoffer Q run as standard, with Haigis available as an option. Lens power for the planned implant therefore comes from the same readings under the formula the surgeon prefers.

A profile for every surgeon

Up to five user profiles hold settings for biometry and five for pachymetry, and each physician setting carries 10 editable IOL slots. A rotating team can share one console, keeping each surgeon's constants in place.

Optional pachymetry for refractive work

The pachymetry option measures corneal thickness from 100 to 1100 µm across three ranges, with a LASIK mode that records three points in each of four phases. The same console therefore covers refractive planning and cataract work.

A printed report at the bench

The built-in thermal printer prints the current screen or a full patient report. Readings and calculated lens powers print to paper from the console, without a separate printer.

Seven interface languages

The touch screen runs in German, English, Spanish, French, Italian, Japanese and Portuguese. International teams read the menus in their working language.

A built-in eye model for probe checks

The contact eye model sits in the console so that you can test a probe against a known target at any time. The test object is part of the unit.

A 4.85 kg console

The unit weighs 4.85 kg and measures 279 × 305 × 305 mm. It moves easily between rooms, and four threaded holes in the base allow fixed mounting.

A-scan biometry at 10 MHz

The biometry probe works at 10 MHz ±1 MHz. It covers axial lengths from 15 to 39 mm, with a theoretical accuracy of ±0.05 mm and a clinical accuracy of ±0.1 mm.

Adjustable gain from 40 to 80 dB

Gain adjusts from 40 to 80 dB, which lets the operator shape the waveform to the eye on the table. Pachymetry gain adjusts automatically.

Biometry readout

The display shows ten axial length readings, the average axial length, the standard deviation, lens thickness, anterior chamber depth and vitreous length. All of them appear on one screen.

Biometry memory

Memory holds 10 biometry measurements per eye, five physician settings and 10 IOL slots per setting. Slots are editable, so lens constants follow the surgeon.

Six IOL formulas

Holladay, SRK II, SRK/T, Binkhorst II and Hoffer Q come as standard, and Haigis is an option. The surgeon selects the formula for each calculation.

Velocity and age compensation

Velocity is programmable for each eye segment. An age compensation option adds age-related velocity compensation for natural lenses.

K adjustment and IOL constants software

Optional K adjustment software supports eyes that have had refractive surgery. Optional IOL constants software customises the constants held in each physician setting.

Probe options for biometry

The biometry probe works with or without its spring-loaded applicator, in immersion or on a slit lamp adapter. A built-in contact eye model supports probe checks.

Optional 20 MHz pachymetry probe

The pachymetry probe works at 20 MHz ±2 MHz and is available straight or angled at 45°. Resolution is ±1 µm and accuracy is ±5 µm.

Pachymetry ranges and bias.

Three ranges cover 100–350, 400–700 and 300–1100 µm. Bias can be an actual value, a percentage from 0 to 30%, or an absolute value from −999 to +999 µm.

Single Point, Map and LASIK pachymetry modes

Single Point mode takes up to 10 programmable points and shows minimum, average, standard deviation and adjusted IOP. Map mode records 25 points, and LASIK mode shows the minimum reading, flap achieved, potential ablation, ablated and potential enhancement.

SVGA colour touch screen

The 800 × 600 SVGA LCD has a touch screen with adjustable brightness, and a stylus rests on top of the console. An external SVGA output drives a separate monitor.

Built-in thermal printer

The printer prints the current screen or a full patient report. Reports leave the console on paper at the end of each session.

Interfaces and storage

The rear panel includes Ethernet, USB, RS232, external SVGA, a footswitch, and probe connectors. A CompactFlash slot on the side stores patient data and accepts software upgrades.

Audible feedback

The speaker beeps each time a reading is stored. In Super Auto pachymetry mode, it also provides voice confirmation.

Reported acoustic output

The manufacturer states that the acoustic output complies with the FDA acoustic limits and IEC 60601-2-37. Peak negative pressure is at or below 1 MPa, beam intensity is at or below 20 mW/cm², and SPTA is at or below 100 mW/cm².

The OcuScan RxP suits ophthalmology clinics and cataract planning departments that want A-scan biometry with six IOL formulas on a hands-free console. A foot pedal, three capture modes and per-surgeon profiles make a shared console practical for a rotating team. Optional pachymetry software extends the same unit to corneal thickness and LASIK phases, and the built-in printer prints the report at the bench. Seven interface languages let international teams work in their own. It performs best in biometry, measuring axial lengths of 15 to 39 mm to a clinical accuracy of ±0.1 mm.
