Both visual acuity and refractive results improved in patients undergoing deep intrastromal arcuate keratotomy with in situ keratomileusis for treatment of high astigmatism after keratoplasty, according to a study.
The two-step DIAKIK procedure was performed in 20 eyes of 20 patients in the prospective study. The femtosecond laser surgery involved two intrastromal arcuate keratotomies and development of a corneal flap, followed by excimer photoablation after reopening the flap at least 1 month later. At 24 months, both UDVA and CDVA were statistically significantly improved, from 1.12 logMAR
