Abstract | INTRODUCTION: Corneal endothelium is a single layer of cells, which do not regenerate. Damage to the endothelium can take place in the course of certain diseases and after intraocular operations. When the number of endothelial cells decreases, corneal decompensation can occur. Pre- and postoperative measurement of the number of the corneal endothelial cells can help assess the degree of corneal damage during the surgery. PURPOSE: MATERIAL AND METHODS: 365 patients (114 men and 251 women aged 19 to 91 years) undergoing phacoemulsification were examined preoperatively and postoperatively at 4 weeks. 68 eyes underwent phacoemulsification through a 1.8 mm microincision and 297 eyes through a standard 2.75 mm incision. Patients were operated on by four surgeons. RESULTS: There was a significant difference in the postoperative endothelial cell loss relative to the degree of cataract hardness (p < 0.001). Endothelial cell loss was significantly higher in patients aged 71 and above than in the remaining age groups. Significant differences in the postoperative endothelial cell loss were observed in relation to the clear corneal incision size (p < 0.01). Preoperative best corrected visual acuity influenced the postoperative endothelial cell loss in a statistically significant way (p < 0.05). Endothelial cell loss was strongly influenced by the surgeon's experience. CONCLUSIONS: Surgeon's experience, hardness of cataract, type of corneal incision, age and preoperative visual acuity influenced endothelial cell loss at 4 weeks following uneventful phacoemulsification, however such factors as sex and intraocular pressure showed no statistically significant influence on corneal endothelial cell loss.
