Abstract Details


To determine the long term state of the corneal endothelium of patients after radial keratotomy (RK) using endothelial microscopy (EM).


Ufa Eye Research Institute, Russia


EM was performed on 81 eyes in 46 patients after RK (study group) and 70 eyes of 36 patients with refractive-axial myopia of high to medium (control group). The average age in the study group was 52.1±5.8 years (39-63), in the control group – 53.6±6.3 years (39-64). The average prescription of RK – 22.7±2.7 years (16-29). Patients with concomitant ocular pathology that could lead to loss of endothelial cell density (ECD) from both groups were excluded. The study was performed on endothelial microscope EM-3000 (Tomey, Japan). ECD, the coefficient of variation (CV) and percentage of hexagonal were measured.


ECD in the control group averaged 2677.71±170.6 cells/mm2, in patients after RK – 2026.53±305.4 cells/mm2 (p<0.05). Reduction of ECD in the study group compared with the control taken as the norm was essential and achieved 24.3%. In the study group CV was 0.44±0.07, in the control group – 0.29±0.04 (p<0.05). Percentage hexagonal cells in patients after RK was 40.4±11.2, in the control group – 68.8±7.5 (p<0.05).


In the long term after radial keratotomy patients showed a significant reduction in the density of endothelial cells, increasing the coefficient of variation in cell size and a decrease in the percentage hexagonal.
