[TPD ophthalmic solution (mixture of tropicamide, phenylephrine hydrochloride, and diclofenac sodium) for cataract surgery].

PURPOSE: We made a TPD ophthalmic solution by combining tropicamide solution(Mydrin-P: T), phenylephrine hydrochloride(Neosynesin Kowa: P) and diclofenac sodium(Diclod: D), and evaluated its efficiency in mydriasis during cataract surgery compared to T, P, and D. SUBJECTS AND METHODS: Twenty-five eyes(19 patients) were given either TPD solution(10 eyes) or T, P, and D solution(15 eyes), and the treatment was given six times before surgery. Pupil diameters were measured before and after surgery. RESULT: The operation time was 10.0 +/- 5.2(mean +/- standard deviation) minutes in the TPD group, and 9.0 +/- 3.6 minutes in the T, P and D group. The preoperative and postoperative one pupil diameter was 8.65 +/- 0.34 mm and 8.20 +/- 0.35 mm in the TPD group and 8.80 +/- 0.49 mm and 8.37 +/- 0.61 mm in the T, P, and D group, respectively. The rate of miosis was 5.1 +/- 4.2% in the TPD group and 4.8 +/- 5.1% in the T, P, and D group, respectively. There was no statistically significant difference between the two groups. CONCLUSION: TPD ophthalmic solution maintains the mydriasis as potent by as T, P and D solution.
