This preliminary study included nine patients (nine eyes) with a mean spherical equivalent refraction of 2.50±3.60 D after penetrating keratoplasty. The IntraLase femtosecond laser was used to make paired 70° arc length incisions at 80 percent depth of the corneal thickness. The mean optical zone was 5.9 mm. The side cut was 90°. The three-month follow-up showed good predictability. Mean refractive astigmatism decreased by 6.00 D, mean keratometric value decreased by 4.60 D. Mean spherical equivalent refraction did not change significantly, and there was a statistically insignificant increase in BSCVA.
