Postkeratoplasty astigmatism was evaluated during examinations 1, 3, and 6 months postoperatively and 2 months after completing suture removal.Results: Twenty-four eyes had single running sutures, 16 eyes had interrupted sutures, and in 14 eyes the suturing technique used was combined interrupted and running sutures. Mean age was 25.6 &plusmn; 5.9 years, 27.3 &plusmn; 6.8 years, and 26.5 &plusmn; 5.7 years (P = 0.422), and postoperative astigmatism 1 month after surgery was 3.79 &plusmn; 1.19 D, 5.56 &plusmn; 1.78 D, and 4.21 &plusmn; 1.55 D in the three groups, respectively (P = 0.012). However, 2 months after completing the suture removal, final postoperative astigmatism was 3.43 &plusmn; 1.44 D, 3.87 &plusmn; 1.38 D, and 3.71 &plusmn; 1.46 D (P = 0.846). Final astigmatism less than 4 D was seen in 18 cases (75%) in the single running group, nine cases (56.2%) in the interrupted running group, and nine cases (64.2%) in the combined interrupted and running group (P = 0.08).Conclusion: Postkeratoplasty astigmatism is comparable with three different suturing techniques used in patients with keratoconus after completing suture removal in DALK. Due to earlier suture removal in DALK, the type of suturing technique used is not considerably important.Keywords: astigmatism, deep anterior lamellar keratoplasty, suturing technique Acar BTVural ETAcar SDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2011, Iss default, Pp 425-428 (2011)
