Performing Measurements Overview The Accutome A-Scan Plus is very simple to operate, and has advanced features to help you obtain the best possible measurements. The Accutome A-Scan Plus takes measurements by sending a signal through the eye through the ultrasonic probe. The signal echoes off the various parts of the eye (cornea, lens, retina) and returns a signal through the probe.

How to Set the Eye Type When the Accutome A-Scan Plus is set up at the factory, it is equipped with predefined eye types and specific velocities for the predefined eye types. Descriptions of the factory installed eye types and their characteristics are given below, followed by instructions on modifying eye types on a per patient basis.
Page 156: Eye Type Materials And Velocities
Accutome A-Scan Plus User’s Guide Note: All eye types, including Aphakic, have an assumed cornea of 0.55 mm at a velocity of 1641 m/sec. This assumption is included in the ACD measurement. Eye Type Materials and Velocities The tables below list the preset eye types and define the materials and velocities for each eye type.

Page 200: Calculating Iol Power After Corneal Refractive Surgery
Calculating IOL powers for post refractive surgery patients is an evolving topic and requires research and careful planning on the part of the ophthalmologist. The methods and formulas presented by the Accutome A-Scan Plus for this type of patient should only be used by a qualified individual who has done due diligence to determine the best method, and how to execute that method, for each patient.
Page 201: Determining Corneal Power After Refractive Surgery
The K value (corneal power or corneal curvature) for patients that have had corneal refractive surgery cannot be determined using common methods. Four K Post formulas, or methods, are available in the Accutome A-Scan Plus to determine the current corneal power for refractive patients (Kpost).
Page 202: Changing Rx Surg Field To Yes
Accutome A-Scan Plus User’s Guide The Kpost calculation methods are listed in order of preference, with the Clinical History method widely accepted as the most accurate. The Clinical History method is the default for new patients. For the refractions entered, the vertex of the refraction is stored and becomes the default for the next patient.
