Schwarzenbacher L, Schartmüller D, Roeggla V, et al. - Researchers conducted this prospective interventional case series to examine corneal astigmatism (CA) reduction and corneal optical quality after surface-penetrating femtosecond laser arcuate keratotomies (Femto AK) considering anterior (CA_ant) and posterior corneal curvature (CA_post), total corneal refractive power astigmatism (CA_tot), and corneal higher-order aberrations (HOAs) through one year. The sample consisted of 43 patients (43 eyes) with age-related cataract and CA_tot between 1 and 3 diopters [D]. Efficient and stable corneal astigmatism reduction within 1 year after surgery was shown by paired surface-penetrating keratotomies produced by a low-energy femtosecond laser. With lower HOAs than preoperatively, the optical quality of the cornea was preserved.
