To analyze the effect of femtolaser-assisted keratotomy on corneal astigmatism (anterior, posterior and Total corneal refractive power) measured by Scheimpflug tomography after laser lens surgery.
This study investigated patients' eyes with low to moderate total corneal refractive power determined with Scheimpflug tomography (Pentacam HR) after penetrating femtosecond laser-assisted keratotomy (pFLAK) and laser lens surgery. The anterior corneal astigmatism, posterior corneal astigmatism and total corneal refractive power were determined before, 1 month and 3 months after lens surgery. Vector analysis according to the Alpins' method was used to calculate surgically induced astigmatism (SIA).
