Résumé
The purpose of this prospective study is to evaluate the effects of different suturing techniques in perforating keratoplasty surgery, in order to identify the most effective in reducing post-operative astigmatism. We analysed data from patients who underwent penetrating keratoplasty for different indications. All interventions were performed by the same surgeon. Patients were subjected to a follow-up of at least 12 months after surgery, during which astigmatism (assessed by keratometry, topography and refraction) best-corrected visual acuity (BCVA) and complications were evaluated. A total of 100 eyes from 100 patients were included and were randomly assigned to five different groups, each one featuring a different suturing technique: interrupted (INT), single running (SRS), double running with two 10-0 sutures (DRS), double running antitorque with two 10-0 sutures (DRSa), double running with both 10-0 and 11-0 sutures (DRS with 11-0). There is a statistically significant difference in astigmatism after surgery between the double running sutures groups and the others with different techniques. However, there is no statistically significant difference between the INT and the SRS group; moreover, there is no statistically significant difference between the different groups with double running sutures (DRS, DRSa, DRS with 11-0). There is no statistically significant difference in BCVA values among the five groups. The wound leak rate was 10% in the INT group, 5.3% in the SRS group and 0% in all groups with double running sutures. In penetrating keratoplasty surgery, the double running suture technique reduces postoperative astigmatism, provides faster visual rehabilitation and features lower complication rates when compared to techniques featuring single running and interrupted sutures. No significant difference in terms of postoperative astigmatism or complication rates was observed among patients receiving double running suture techniques.

Background
UNASSIGNED
The purpose of this prospective study is to evaluate the effects of different suturing techniques in perforating keratoplasty surgery, in order to identify the most effective in reducing post-operative astigmatism.
Methods
UNASSIGNED
We analysed data from patients who underwent penetrating keratoplasty for different indications. All interventions were performed by the same surgeon. Patients were subjected to a follow-up of at least 12 months after surgery, during which astigmatism (assessed by keratometry, topography and refraction) best-corrected visual acuity (BCVA) and complications were evaluated. A total of 100 eyes from 100 patients were included and were randomly assigned to five different groups, each one featuring a different suturing technique: interrupted (INT), single running (SRS), double running with two 10-0 sutures (DRS), double running antitorque with two 10-0 sutures (DRSa), double running with both 10-0 and 11-0 sutures (DRS with 11-0).
Results
UNASSIGNED
There is a statistically significant difference in astigmatism after surgery between the double running sutures groups and the others with different techniques. However, there is no statistically significant difference between the INT and the SRS group; moreover, there is no statistically significant difference between the different groups with double running sutures (DRS, DRSa, DRS with 11-0). There is no statistically significant difference in BCVA values among the five groups. The wound leak rate was 10% in the INT group, 5.3% in the SRS group and 0% in all groups with double running sutures.
Conclusion
UNASSIGNED
In penetrating keratoplasty surgery, the double running suture technique reduces postoperative astigmatism, provides faster visual rehabilitation and features lower complication rates when compared to techniques featuring single running and interrupted sutures. No significant difference in terms of postoperative astigmatism or complication rates was observed among patients receiving double running suture techniques.
