IOL calculators provide similar results in patients with LASIK history

Different IOL calculators provided similar results in patients with a history of LASIK surgery, according to a study published in the Journal of Refractive Surgery.
Thomas Kohnen, MD, PhD, and colleagues wrote that corneal refractive surgery has been shown to complicate the accuracy of IOL power calculations because the surgery alters the relationship between the anterior and posterior corneal refractive power.
“Formulas that predict the exact lens position from the corneal curvature are known to be inaccurate when corneal curvature and refractive power are altered by refractive surgery,” they
