Intracameral Triamcinolone Acetonide Versus Topical Dexamethasone: A Comparison of Anti-inflammatory Effects After...

Study objective and design The objective of this study was to determine the effectiveness of triamcinolone acetonide when used as a single dose as compared to the topical use of dexamethasone to control the inflammation after phacoemulsification. The study was a randomized controlled trial conducted in the Department of Ophthalmology at the District Headquarter (DHQ) Teaching Hospital, Dera Ghazi Khan, from March 1, 2018, to August 31, 2019. Materials and methods Eighty patients were included in the study. All patients were assigned to two groups of 40 patients each using the lottery method. Group A patients were treated with a 1-mg intracameral injection of triamcinolone acetonide postoperatively after phacoemulsification. Group B patients were administered 0.1% dexamethasone eye drops with a dosage of one drop every four hours for four weeks. Postoperative follow-up was planned for day one, day seven, and day 28. Results The postoperative inflammation cell values of Group A on day one, day seven, and day 28 were 1.68 ±0.84, 0.22 ±0.15, and 0.12 ±0.23, respectively, while the postoperative inflammation cell values of Group B on day one, day seven, and day 28 were 1.91 ±0.75, 0.28 ±0.15, and 0.09 ±0.20, respectively. The postoperative inflammation flare values of Group A on day one, day seven, and day 28 were 0.31 ±0.37, 0.03 ±0.44, and 0.00 ±0.22, respectively, while the postoperative inflammation flare values of Group B on day one, day seven, and day 28 were 0.25 ±0.26, 0.22 ±0.46, and 0.02 ±0.18, respectively. Conclusion The efficacy of both modes of treatments is comparable; however, triamcinolone acetonide is preferable to dexamethasone, as its intracameral injection generally results in better compliance than multiple dosages of topical eye drops of dexamethasone.
