Summary:
The purpose of the research was to assess the quantitative and qualitative state of the corneal endothelium after thermokeratocoagulation in a long-term period. Material and Methods. The main group consisted of 18 patients (36 eyes) after thermokeratocoagulation, which was performed from 19 to 28 years ago. The control group consisted of 22 patients (44 eyes) aged from 45 to 58 years (middle age 51.3±3.2 years) from refraction and axial hypermetropy various degree without the previous surgical interventions. The research was performed on a non-contact mirror scanning microscope EM-3000 (Tomey, Japan). Results. The endothelial cells density in the main group averaged 2245.4±316.2 cells / mm2, in the control group 2661.7±169.2 cells / mm2 (p<0.05). The coefcient of endothelial cell size variability counted 0.34, in the control group 0.26 (p<0.05). The percentage of hexagonal corneal endothelial cells in patients after thermokeratocoagulation averaged 53.7±14.9 % in patients of the control group 74.3±6.5 % (p<0.05). Conclusion. In the long-term period patients showed a statistically signifcant decrease in the corneal endothelial cells density, a decrease in the percentage of hexagonality and an increase in the coefcient of cell size variability.
