Since my husband has to have a cataract surgery on one of his eyes soon, we have been gathering various information on IOL. We are also reading some medical literature, and one of the confusing things is the definition of IOL power. We need to know the exact definition of the power of a lens in general, and the power of an IOL in particular. We searched for the answer on the Internet, but we didn't get a clear-cut answer for this question. Could you please tell us the exact definition of the power of an IOL in terms of IOL's focal length?
The definition of a diopter is the same the world over and never redifined in IOL calculations. Your formula is for determining powers of IOLs when put into the eye "piggy-back" that is using two IOLs in the eye.
