The Accutome A-Scan Plus provides two methods of capturing measurements; Automatic, or ’Auto’, and Manual. The Automatic mode allows the instrument to determine, based upon user established criteria, when a measurement is captured. The Manual mode allows the user to determine when a measurement is captured.
- Automatic -The user is allowed define the Automatic measurement mode by specifying how a measurement is automatically captured. There are a total of three criteria available and each can be turned off or on by the user on the Setup screen. The criteria are:
Sclera – automatic capture determined by sclera detection
Retina – automatic capture determined by retina detection
Stable – automatic capture determined by measurement stability
- Manual – Using the manual mode of capture you determine when a waveform is good and capture it manually.
pinpoints tissue boundaries.
• Acquires over 4000 points per waveform.
• Continuous display of Axial Length, ACD, Lens Thickness, and Vitreous dimensions.
• Audible feedback of contact, signal quality, and capture.
• Immersion mode yields improved accuracy. Contact mode also supported.
• Automatically or Manually capture up to 5 waveforms for each eye.
• Fully Automatic or Operator Assisted adjustable Gain, Time Gates, and Amplitude Thresholds. Modify
all waveform parameters using real-time or frozen waveforms.
• On-the-Fly customization handles unique patients.
• Predefined Eye Types and Velocities handle most situations such as phakic, dense cataract,
pseudo-phakic, aphakic and even silicone oil filled eyes. All velocities are fully adjustable.
• Custom Eye Types and Material Velocities can be created to handle individual preferences, special
pathologies, or future trends.
• 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 ametropic IOL powers for dozens of lenses, viewed three 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 Lens Constants is easy and straightforward, encouraging improved patient outcomes.
• Maintains individual Lens Constants for each formula. Clearly identifies which Lens Constant is used
with the selected formula.
• Initially calculates all Lens Constants from a single entered A-Constant, ACD, or Surgeon Factor.
Thereafter, entering postoperative results will quickly converge upon optimal personalized Lens Constants.
• Save complete Patient Records containing all measurements, calculations and settings in effect at the
time of the original examination.
• Recall Patient Records to review, remeasure, recalculate, or print even after the patient has left the office!
• Waveforms can be reviewed, even zoomed. Manipulate Gates, Thresholds, Eye Types and Velocities to
obtain updated measurements.
• Calculations can be confirmed or updated. Calculate “what-if” scenarios. Even use different lenses,
formulas, updated personalized Lens Constants, target refractions, etc.
• Print Patient Records in any desired Printout Format.
A-scan is an abbreviation for amplitude modulation scan using high frequency sound waves (ultrasound). It provides information in one dimension, such as length. In ophthalmology, A-scan ultrasound biometry is used to measure the axial length of the eye, which is important in cataract surgery and for some other conditions such as orbital tumors.
The Accusonic does have serial port connections that in theory should connect with your EHR program. Always speak with your EHR company to ensure integration.
