Accutome A-Scan Plus Connect User’s Guide
Features
The Accutome A-scan Plus Connect is designed for easy access to all screens
and functions.
The windows based software and proprietary universal interface provides
unsurpassed ease of use and the straightforward Graphical User Interface guides
you through every operation.
What you can’t see on the surface is also important. Industry-leading signal
acquisition and processing helps you assure accurate measurements. Reliable
design and efcient manufacturing provide scal value. Upgradable software
protects your investment.
The A-Scan provides the following general features:
• Use on any Windows based computer
• Universal interface and probe
• Easily updated software
• Provides a variety of printouts
• Portable
Measurements
The accuracy of the Accutome A-Scan Plus Connect measurement is provided
by the following:
• High-resolution, real-time waveform display
• High-speed digitalization acquires over 4000 points per waveform
• Continuous display of Axial Length, ACD, Lens Thickness, and Vitreous
dimensions
• Audible feedback of contact and capture
• Immersion mode yields improved accuracy - Contact mode also supported
• Automatically or Manually capture up to 5 waveforms for each eye
• Adjustable Gain, Velocities, Gates, and Amplitude Thresholds
• Modify all waveform parameters using real-time or frozen waveforms
• Predened Eye Types and Velocities handle most situations such as phakic,
dense cataract, three types of pseudo-phakic, aphakic, silicone oil lled,
and even phakic ICL eyes. All velocities are fully adjustable
• Custom Eye Types and Material Velocities can be created to handle individual
preferences, special pathologies, or future trends
• Highly sensitive 10MHz composite Broadband probe features a xation
light and multiple mounting options

IOL Calculations
The Accutome A-Scan Plus Connect is also a leader in IOL Calculations and
provides the following:
• Modern formulas including Hoffer Q, Holladay, SRK/T, and Haigis
• Compare results of all formulas simultaneously on a single screen for
selected lenses
• Instantly calculates emmetropic and targeted ametropoic IOL powers
for dozens of lenses, viewed four at a time, using the average of selected
waveforms, a single waveform, or manually entered data
• Conveniently group lenses by favorite designation such as surgeon, user,
type, manufacturer, etc.
• Personalization of IOL Constants is easy and straightforward, encouraging
improved patient outcomes
• Maintains individual IOL Constants for each formula. Clearly identies
which IOL constant is used with the selected formula
• IOL Calculation for Post Refractive Surgery Patients
Components
The components that are standard with each Accutome A-Scan Plus Connect
instrument are:
• Ultrasonic probe
• Control Unit
• Footswitch
• Software CD which contains:
• User’s Guide
• System Software (to be loaded onto PC)
• A-B Type USB Cable
• Test Block
