Enter **Conditions** into the Conditions input line - You can use any of the variables listed at the bottom of this page

Typical entries shown in the list - if the probability comes back 0, then you entered an impossible condition, like axial_length < 21 & axial_length > 22

Or you misspelled the variable name in the conditions (see all legal names at bottom of this page

  • axial_length < 21
  • axial_length < 21 | axial_length > 24
  • axial_length < 21 & flatk > 43.2
  • (flatk - steepk) >= 3.02
  • Note** | means or     & means and

Enter the **Output Measure** into the Output Measure line ** Again You can use any of the variables listed at the bottom of this page

You can only enter ONE Output Measure - if the probability comes back 0, then you entered an impossible condition, like axial_length < 21 & axial_length > 22

Typical Output Measures are listed below - you can also do mathematical functions on them, the most useful being abs -- absolute value and statistical functions like mean, or sd (standard deviation)

  • prediction_error < -0.50
  • abs(prediction_error) < 0.50
  • po_sphere < -1.00

The following is the list of measured variables in this dataset - followed by their common meaning

  • po_sphere ** postop target spherical equivalent
  • prediction_error ** postop prediction error
  • axial_length ** axial length in mm
  • flatk ** flat keratometry (diopters) American Index Refraction
  • steepk ** steepk keratometry (diopters) American Index Refraction
  • acd ** anterior chamber depth (including cornea)
  • sphere ** preop spherical refraction
  • cylinder ** preop cylinder refraction
  • srkt_aconst ** the optimized srkt A constant
  • haigis0 ** the optimized Haigis a0 constant
  • surgical_inducedcyl ** your average induced cylinder in diopters
  • srkt_iol ** Calculated SRKT iol
  • hoff_iol ** Calculated Hoffer Q iol
