Abstract

Purpose: To compare the effectiveness of topical surfactant and 3% sodium chloride (NaCl) in the treatment of corneal edema occurring after cataract surgery. Methods: Ninety eyes of 90 patients with no corneal disease who underwent cataract surgery were included in the study. Thirty eyes without corneal edema comprised group 1. Patients with corneal edema were divided into two groups: those treated with 3% NaCl (group 2, 30 eyes) and those treated with surfactant drop (group 3, 30 eyes). Results: The mean age was 70.8 ± 6.6 years, with no significant age difference between the groups. Preoperatively, there was no significant difference in mean central corneal thickness (CCT) or mean endothelial cell count (ECC) among the groups (P = 0.999). On postoperative day 1, CCT was significantly lower in group 1 (P < 0.001) but did not differ between groups 2 and 3 (P = 0.999). There was no significant difference between groups in terms of ECC (P > 0.05). At postoperative day 7 and 14, CCT differed significantly between groups 1 and 2 (P < 0.001) and between groups 2 and 3 (P = 0.001), with no significant difference between groups 1 and 3 (P = 0.474). ECC was significantly higher in group 1 (P < 0.05), whereas there was no significant difference between groups 2 and 3 (P > 0.05). Conclusion: Topical pulmonary surfactant may be a more effective treatment option than 3% hypertonic NaCl for the treatment of corneal edema that develops after cataract surgery.
