Femtosecond laser may yield better astigmatic keratotomy outcomes in patients with mixed astigmatism

Performing femtosecond laser intrastromal astigmatic keratotomy in patients with low mixed astigmatism improved refractive error after other refractive surgical methods were less successful, a study found.The retrospective study included 112 eyes with low mixed astigmatism after previous refractive surgery that then underwent intrastromal astigmatic keratotomy. Patients were divided into two categories: those who underwent previous excimer laser surgery (47 eyes) and those who did not (65 eyes).
