Experiencia con crosslinking en pacientes mexicanos con queratocono y variables queratométricas como factores pronóstico de agudeza visual

Abstract

Objective: The present study aimed to report the outcomes of patients with progressive keratoconus who were treated via conventional crosslinking (CXL). Method: This retrospective study included 277 eyes of 144 patients with progressive keratoconus who underwent CXL. Topographical measurements were obtained preoperatively and twelve months postoperatively. The best corrected visual acuity (BCVA), flat keratometry (K) value (K1), steep K value (K2), average K value (avgK), K1 axis, K2 axis, pachymetry value and cylindrical value were the studied measures. results: At the 12-month follow-up, the mean BCVA values were improved. Statistically significant decreases in K1 (p = 0,001), K2 (p = 0.000), K1 axis (p = 0.000), K2 axis (p = 0.004) and avgK (p = 0.025) were observed. The correlation analysis revealed that the preoperative BCVA, K1, K2, K2 axis, avgK and cylinder as well as postoperative K1, K2, avgK and cylinder values significantly affected visual acuity at the 12-month follow-up. Conclusions: CXL was an effective treatment to improve best corrected visual acuity. The preoperative and postoperative K values, preoperative BCVA had a statistically significant correlation with BCVA at 12 months after CXL treatment.
