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
