Objective: Pterygium is a fibrovascular connective tissue proliferation extending on the cornea in the interpalpebral space. To relieve the symptoms and signs of pterygium, numerous surgical approaches have been developed. The aim of this study was to investigate the short-term results of the subepithelial dissection technique (D’Ombrain’s Technique) in regard to best-corrected visual acuity (BCVA) and computerized corneal topography (CCT) results. Methods: Eighteen eyes of 15 patients presenting at our clinic have been prospectively investigated and followed for a duration of 1 month. Pre- and postoperatively, a complete ophthalmologic examination and CCT were performed. Statistics were performed using the Wilcoxon’s rank sum test, with the level of significance set at p<0.05. Results: The study included 14 primary and 4 secondary pterygia. Preoperatively mean BCVA was 0.61, and CCT showed a mean astigmatism of 2.60 D. These values were 0.82 (p<0.05) and 1.22 D (p<0.05), respectively, at 1 month. There were no serious intra- or postoperative complications observed. Conclusion: We consider the subepithelial dissection technique in the treatment of pterygium as an effective and safe method in the short-term.
