Personalizing Lens
Constants
Overview One of the great features of the Accutome A-Scan Plus
is the ability to personalize the lens constants used in
calculating lens power. This ability to fine tune lens
constants results in even greater success for patient
outcomes.
*Note: The Personalize IOLs screen does not allow the
pasting of patient data for an eye that has Rx Surg
set to Yes. If you attempt to personalize IOLS with
post refractive surgery eyes the following message
is shown: "Refractive surgery eyes cannot be used."
Personalizing Lens Constants
IOL constant personalization is a method for removing
consistent errors from the entire IOL implant procedure.
It is important that as many variables as possible be
consistent when personalizing constants for an IOL.
These variables include:
Diagnostic Technician
Diagnostic Equipment (A-scan, Keratometer)
Surgical Technique
Surgical Equipment
Patient Pathology
IOL Manufacturer and Model
IOL Calculation Formula
For this reason, the Accutome A-Scan Plus tracks
personalized constants for each IOL and formula
separately.
The process for personalizing lens constants involves
entering postoperative results and allowing the
Accutome A-Scan Plus to recalculate the constants used
in the calculation formulas. The instrument tracks all the
data entered in the postoperative results and optimizes
all the data to determine the new formula constant.
