Intraocular lens power requirements for humanitarian missions

Abstract

The spreadsheet-based IOL power prediction model calculated an ideal distribution of IOLs to order for humanitarian cataract surgery. It is generalizable to missions of any size and should help planners minimize costs while ensuring excellent refractive outcomes.

Intraocular lens power calculation for humanitarian missions based on partial biometry

“…Imam et al 11 suggest keeping a supply of the few most common IOL powers as a way to limit the cost and the complexity of logistics. Lombard et al 12 addressed this problem with a spreadsheet-based IOL power prediction model to aid C5.00 to C4.01 planners in minimizing the number of excess IOLs and minimizing cost while allowing more than 95% of patients to receive suitable IOL powers. The use of complete biometry for IOL calculations results in improved uncorrected vision, and we believe an effort should be made to obtain preoperative measurements of both K and AL for all patients.…”
