The axial length (AL) is the distance between the anterior surface of the cornea and the fovea and usually measured by A-scan ultrasonography or optical coherence biometry. The AL is the most important factor in IOL calculation: A 1-mm error in AL measurement results in a refractive error of approximately 2.88 D or about 3.0-3.5 D error of IOL power in an average eye. A mean shortening of 0.25–0.33mm can translate into an error of IOL power by approximately 1 D iphone keeps buffering on black screenWebLow power intraocular lenses We believe that implantation of low diopter power IOLs in eyes with myopia carries no apparent increased risks when the usual precautions concerning cataract surgery with implantation are observed.
