A new algorithm offers accurate IOL calculations in eyes undergoing cataract removal after previous laser refractive surgery, according to a study. Wolfgang Haigis, MS, PhD, devised the Haigis-L ...
PARIS — A new formula based on precise measurements of the eye allows IOL power calculation without a surgeon “fudge factor,” according to presenters here. The formula is accurate even for eyes that ...
To demonstrate a quick way of calculating the optical difference between two refractions using vector analysis, and to express this as a score for examination purposes. An existing formula is applied, ...
