- W2469620525 abstract "The authors assess the outcomes of postkeratoplasty single running suture adjustment in 14 eyes (16 adjustments) of 14 patients (4 women, 10 men). The average age of patients was 39.68 year (ranging from 19 to 70 years). The suture adjustment was done in time span 2 to 39 weeks following after perforating keratoplasty (PKP), average 7.5 weeks. Follow up time was from 1 to 12 months, average 10.8 months. The value of keratometric and topographic astigmatism before suture adjustment were compared to the value of keratometric and topographic astigmatism 1, 6 and 12 months after suture adjustment. The changes of corneal refractive power and changes of uncorrected and best-corrected visual acuity were noticed as well. The mean value of keratometric astigmatism 7.47 +/- 2.69 D and mean topographic astigmatism 7.75 +/- 3.25 D before suture adjustment was decreased to 4.92 +/- 2.41 D and 4.83 +/- 1.46 D respectively one month after suture adjustment. These reductions of keratometric and topographic astigmatism (2.55 D and 2.92 D respectively) were statistically significant (p = 0.0416, and p = 0.0211 respectively). The mean keratometric astigmatism was still significantly lower (p < 0.05) after 6 and 12 months after suture adjustment in comparison to status before suture adjustment. In assessment of topographic changes we noticed small continuous increasing of astigmatism (1.27 D after 6 months and 0.2 D after 12 months after suture adjustment). These changes of topographic astigmatism were not statistically significant. The changes of mean corneal refractive power were not statistically significant as well. The mean uncorrected visual acuity increased significantly (from 0.13 to 0.34, p < 0.05) 1 month after suture adjustment. This improvement of uncorrected visual acuity was not significant after 6 and 12 months after suture adjustment. The best-corrected visual acuity improved from 0.37 to 0.61 after one month after suture adjustment but was not statistically significant and stayed still at the same level with minimal changes during follow up time." @default.
