PURPOSE: To compare the effects of a fortified balanced salt solution (fSS) and Ringer's lactate solution (Ringer) on anterior chamber (AC) inflammation in patients undergoing phacoemulsification.
SETTING: Tianjin Medical University Eye Hospital, Tianjin, China.
DESIGN: Prospective masked controlled trial.
METHODS: 80 patients (40 patients with regular cataract and 40 cataract patients with diabetes mellitus [DM]) were randomized to receive either fSS (n = 40) or Ringer's solution (n = 40). Anterior-segment optical coherence tomography was used to evaluate AC cells and flare. Transepithelial electrical resistance (TEER) and zonula occludens-1 (ZO-1) immunofluorescence were used for tight junction examination. Monocytic leukemia cell line (Tohoku Hospital Pediatrics-1 [THP-1]) transmigration assay was performed to observe the effects of the 2 perfusates on the inflammatory response in vitro.
RESULTS: In patients with regular cataracts, postoperative AC cells and flare on the 1st and 7th days were not significantly different between the Ringer and fSS groups. However, in cataract patients with DM, AC cells were higher in the Ringer group than in the fSS group ( P = .003) on postoperative day 1. The AC flare was also significantly higher in the Ringer group than in the fSS group ( P < .0001). No significant differences between the groups were observed on day 7. Compared with Ringer, fSS increased the TEER value and ZO-1 content and reduced the adhesion of THP-1 cells.
CONCLUSIONS: The results of this study indicated that early postoperative AC inflammation is more severe in patients with cataracts and DM. In addition, fSS attenuates inflammation by protecting the blood-aqueous barrier and inhibiting the exudation of inflammatory cells.
