Resumen

DOMINGO GORDO, B; CONEJERO ARROYO, J  y  BALADO VAZQUEZ, P. Residual myopia after penetrating keratoplasty for keratoconus. Arch Soc Esp Oftalmol [online]. 2004, vol.79, n.1, pp.07-11. ISSN 0365-6691.

Purpose: To study the results of penetrating keratoplasty for keratoconus analyzing the differences in ultimate spherical equivalent according to graft size and the trephine used in the recipient Material and methods: Retrospective study of 38 patients that were divided into three groups. Group A is composed of patients with a 0.50 mm donor-recipient difference, 0.25 mm in group B and same-sized in group C. In each group visual acuity, spheric equivalent, keratometry and other parameters were assessed. Statistical analysis was performed by comparing the means of the parameters evaluated. Results: We found a better final visual acuity in group C when compared with group A, and a lower spherical equivalent when we compared groups A with C and A with B. The results were better in those groups where the donor-recipient difference was smaller. Conclusions: We believe that it is convenient to minimize the size difference between donor and recipient or to use same-sized trephines to diminish the final spheric equivalent.
