Abstract

Objectives: To report the evaluation of keratoconus progression after Ferrara intrastromal corneal ring segment implantation. Materials and Methods: In this retrospective study, we evaluated progression in eyes with keratoconus after intrastromal corneal ring segments implant. It was considered progression when the increase of the maximum keratometry was greater than 1 Diopter (D) when comparing the first postoperative exam (6 months), and the last exam. Results: There was no progression after the surgery. When comparing the mean maximum keratometry pre-op (46.75D) and the pos op data (46.01D), with statistically significant (p-value: 0.047). An increase of less than 1D in these patients was also observed. In a descriptive analysis, 41 eyes were studied: 8 eyes had an increase greater than 1D, 19 eyes had an increase equal or less than 1D and 14 eyes maintained the initial D or had decreased within the years. Analyzing patient?s ? 21 years, the variation of maximum keratometry between 6 months postoperatively was higher in this group (1.82 D ? 3.11) than in the group with more than 21 years (0.5 D ? 1.27). This data was not statistically significant (p=0.148). Conclusion: This study showed an evolution of maximum keratometry in the postoperative period of the intrastromal ring surgery. However, this increase in the stipulated time of the study was less than 1D in the majority of patients.
