The aim of this study is to determine the principal factors that influence endothelial cell loss three month post cataract surgery.
Methods: Multi center observational Cohort study, inclusion period from 12/01/2022 to 10/06/2022. One hundred and seventy-five eyes of hundred and four patients who have appointment for cataract surgical indication were included. The percentage of corneal endothelial cell loss was quantified using specular microscopy before and 3 months after the surgery.
14 variables (pre-operative and intra-operative) that could be associated to endothelial cell injury were selected.
A bivariate analysis of relationship between these factors and endothelial cell loss at 3 months was performed by simple linear regression (Wilcoxon and Fischer tests). Multivariate analysis was performed by multiple linear regression in order to identify the factors independently related to endothelial cell loss.

| Measure | Description | Time Frame |
|---|---|---|
| The difference in central corneal endothelial cell density (cells/mm²) between the 1st preoperative measurement and the postoperative measurement at 3 months. | Specular counts were performed by the orthoptists, residents or physicians of the department using a Nidek CEM-530 specular microscope with automated central cell counting without corneal contact. Three measurements were performed at each consultation and the average of these three measurements was reported. | 3 months after cataract surgery |
| Measure | Description | Time Frame |
|---|---|---|
| Postoperative visual acuity | best spectacle corrected visual acuity is evaluated using Monoyer scale, scores ranging from 1 to 10, higher scores mean a better outcome; score 10 is the best. | 3 months after cataract surgery |
| Postoperative corneal edema |
