Prospective Randomized Clinical Trial Evaluating Efficacy and Safety of A New Ophthalmic Viscosurgical Device In Patients Undergoing Cataract Surgery.
Journal of Cataract and Refractive Surgery 2024 May 8
PURPOSE: To evaluate the efficacy and safety of Bio-Hyalur LVD compared to Viscoat® ophthalmic viscosurgical device (OVD) in patients undergoing routine cataract surgery.
SETTING: Two tertiary eye care hospitals in Italy.
DESIGN: Prospective randomized clinical trial.
METHODS: This study compared the outcomes of Bio-Hyalur LVD versus Viscoat® ophthalmic viscosurgical device in patients undergoing standard cataract surgery with phacoemulsification and intraocular lens implantation from January 2021 to April 2022. The primary outcome was mean change in IOP at 6 hours. Secondary outcomes included 1-, 7-, 30- and 90-day mean intraocular pressure (IOP), 7-, 30- and 90-day best corrected visual acuity, endothelial cell density (ECD), change in central corneal thickness (CCT) and complications including intraocular inflammation.
RESULTS: A total of 84 eyes of 84 patients (n = 41 in the Bio-Hyalur LVD group and n = 43 in the Viscoat group) were screened, enrolled, randomized, and included in the analysis. Mean change in IOP was significantly higher in the Viscoat group than in the Bio-Hyalur LVD group 6 hours (p = 0.034), 7 days (p < 0.001), 30 days (p < 0.001) and 90 days (p = 0.003) postoperatively. Mean change in UDVA and CDVA was significantly higher in the Bio-Hyalur LVD group 30 and 90 after surgery. No significant differences in ECD, CCT and complication rates were observed between groups at any time point.
CONCLUSION: Bio-Hyalur LVD OVD is safe and effective for use in patients undergoing routine cataract surgery. Bio-Hyalur LVD OVD did not confer a higher risk of postoperative increase in IOP.
