The IOL Calculator is meant to serve as an adjunct tool to assist physicians in selecting the appropriate IOL for a particular patient. It is intended to be used in conjunction with a comprehensive ophthalmic examination and the appropriate diagnostic tests and measurements necessary for cataract surgery candidates with a history of prior refractive surgery. The results obtained by the calculator are not intended to serve as medical or surgical instruction from the ASCRS, or be definitive; nor can ASCRS guarantee that the results will be accurate in every case. Physicians who use the calculator must arrive at their own independent determinations regarding the proper treatment for their patients and are solely responsible for the refractive outcome. By using the IOL Calculator, you agree to waive and hold ASCRS and authors harmless from any claims you may have arising out of your use of this tool.
