Correction ratio and vector analysis of  femtosecond laser arcuate keratotomy for  the correction of post-mushroom profile  keratoplasty XXXX .

@entity1 @entity9604 @entity940
PURPOSE: To evaluate the refractive and keratometric effect of arcuate keratotomy using femtosecond technology in @entity1 with high post-keratoplasty @entity940 with a mushroom profile. SETTING: Enaim Refractive Center, @entity9604 -Aviv, Israel. DESIGN: Noncomparative prospective interventional case series. METHODS: The arcuate depth incision was set to 80% of the minimal graft thickness, with a 60-degree angle. The mean diameter was 5.79 mm    0.32 (SD) according to the graft size. @entity1 evaluation included logMAR corrected distance visual acuity (CDVA), refraction, keratometry (K), and a complete eye examination. RESULTS: Twenty-seven eyes of 27 @entity1 after keratoplasty surgery were included. Both uncorrected distance visual acuity and logMAR CDVA improved after surgery. The preoperative mean logMAR CDVA was 0.29    0.37 (SD), which improved by 1 line (to 0.19    0.10; P = .01). The mean refractive @entity940 was -8.43    2.80 diopters (D) (range -4.5 to -15 D), and it declined at the 3-month postsurgical follow-up to -4.31    0.23 D (P < .001) and remained stable until the end of follow-up (-3.31    1.39 D; P = 1.00). The K value decreased by 1.18 D (P  < .001). There were no complications or adverse effects during the follow-up period. CONCLUSIONS: Arcuate keratotomies performed with the femtosecond laser showed good results. There was a more than 50% decrease in post-mushroom profile keratoplasty @entity940 as well as stability of the results over 1 year.
