To analyze demographic, clinical, and keratometric outcomes of the second eye in keratoconic patients when the first eye has already been grafted, initially and finally at 12 years.
Retrospective analysis of initial and 12 years visual and keratometric outcomes of the second eye in keratoconic patients when the first one has already been grafted.
A total of 107 patients were included: 66 patients were analyzed at the beginning of the follow-up and at 12 years. There were no statistically significant differences with regard to the correction method from the beginning to the end of the follow-up; 3% of patients underwent crosslinking and 4.5% an intracorneal ring segments implantation. There was no significant progress in corneal opacities (1.5% vs 3.0% at 12 years) or visual comfort (90.9% vs 87.9%). The mean values of best-corrected visual acuity (BCVA) (0.69 vs 0.71 at 12 years, on a decimal scale), cylinder (-2.64 D vs -3.13 D), spherical equivalent, and keratometry (46.34 D vs. 46.49 D) had not significantly changed during the follow-up period. During the follow-up, 41 patients (38.3%) received a penetrating or lamellar keratoplasty on the contralateral eye (63% in the 5 years after the first corneal graft). At the time of the keratoplasty procedure, corneal opacities were seen in 7 patients (17.1%), mean BCVA was 0.26 ± 0.16, spherical equivalent mean was -3.70 D, mean cylinder was 3.89 D, mean keratometry values were 52.65 ± 6.80 D, and mean pachymetry value was 335.50 µm.
This study suggests that the period of risk of keratoplasty in the second eye is significant in the first 5 years following the first keratoplasty. New therapeutic treatments have been made available, allowing for stabilization of the keratoconus decreasing the impact of transplantation.
