    Purpose. Comparative analysis of visual and refractive results after endothelial keratoplasty in DSAEK and DMEK modifications.

    Material and methods. The analysis of visual and refractive results of modifications of endothelial keratoplasty (DSAEK and DMEK).

    Results. Corrected visual acuity after DMEK after 6 months. was an average of 0.2 higher than after DSAEK, 1 year 0.1 higher. Clinical data indicate hypermetropic refractive change after DSAEK surgery. The value of induced astigmatism in 1 year after DSAEK was 0.4 D, and in DMEK it did not exceed 0.1 D. The analysis of higher-order aberrations (EVP) of the anterior surface of the cornea 6 and 12 months after the operation did not reveal a significant difference in the indicators in patients after various modifications of endothelial keratoplasty. The values of the aberrations of the posterior surface of the cornea after performing DMEK was significantly lower than after DSAEK. There was no statistically significant difference in the «total» aberration values (anterior/posterior corneal surface) between the DMEK and DSAEK groups.

    Conclusion. There were no clinically significant differences in refractive changes after DSAEK and DMEK in the remote period after the intervention.

    Key words: cornea, bullous keratopathy, DSAEK, DMEK, graft, aberrations of the highest order.
