IOL Power Calculations for Eyes With Astigmatism
Web27 jul. 2024 · Like toric soft contact lenses, toric IOLs can correct astigmatism because they have different powers in different meridians of the lens. They also have alignment markings on the peripheral part of the lens that enable the surgeon to adjust the orientation of the IOL inside the eye for optimal astigmatism correction. WebA frequently cited study describes how just 1 degree of misalignment results in 3.5% of residual cylinder; 3 degrees of misalignment in 10.5% of residual cylinder; and 30 degrees of misalignment in a total loss of the toric’s astigmatic correcting effect. 1.
