To improve the accuracy of 4th Generation formulas such as the Holladay 2 and Hoffer H so as to consider other patient factors in predicting the ELP
UCLA St. Mary"s Eye Center
A world literature search was done on the biometric measurements of human eyes in large series. The data was collated and analyzed to produce average values for different populations based on race and gender.
The values calculated were used to replace those in the Holladay 2 and Hoffer H formulas to individualize the calculation for the specific patient based on their race and gender.
The Hoffer H-5 formula uses the structure of the Holladay 2 formula and takes into account the demographic specifics of the individual patient based on race and gender. 4th generation formulas use arbitrary average biometric values. These values are completely different in males and females and in different races. The gender/race specific average is used for a specific patient rather than the overall human average.
