Effect of medicinal treatment on epithelial wound healing after phacoemulsification
Abstract
AIM: to compare the dynamics of epithelial wound healing under two different post-op treatments in patients after uncomplicated phacoemulsification.
MATERIAL AND METHODS: This prospective randomized clinical trial included 40 eyes of 40 patients aged 66.4±8.2 years who underwent uncomplicated phacoemulsification with flexible intraocular lens implantation through a 2.2-mm corneal incision. Patients were randomized to receive either dexamethasone 0.1% and diclofenac 0.1% (n=20 eyes, Group I), or bromfenac 0.09% (n=20 eyes, Group II). Also, all patients instilled levofloxacin 0.5%. The dynamics of epithelial wound healing was assessed with the RTVue-100 spectral domain optical coherence tomograph with CAM-L corneal module in the 3D CORNEA mode 2 hours after surgery and on days 1, 3, 5, and 10.
RESULTS: The postoperative period was uneventful in all cases. Two hours after surgery, epithelial defects were found in all eyes and their length did not differ statistically p=0.47. On the first day after surgery, complete epithelization was observed in 30% of cases from Group I and 60% of cases from Group II. The average length of epithelial defects was reliably smaller in Group II than in Group I (p=0.04 respectively). On postoperative day 3, 20% eyes from Group I still had epithelial defects with the average length of 0.45±0.13 mm, while there was only one eye with a 0.2-mm epithelial defect in Group II. Finally, on postoperative day 5, there was a single 0.3-mm epithelial defect in…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 40 participants or records.
