* Compared to HA alone in an in vitro study. Human corneal epithelial cells were grown to confluence. Media were then removed and cells were incubated with test formulations for
30 minutes at 37°C. Test formulations were removed and cells were rinsed 5 times with media before desiccation at 37°C with 45% humidity for 30 minutes. Cell viability was assessed
using an MTS assay.1
† Prospective, parallel, randomized, investigator-masked, single-center clinical study. Eligible patients were scheduled to undergo routine cataract removal and intraocular lens
implantation. Patients were randomly assigned to either standard-of-care (n=20) or SYSTANE® ULTRA + standard-of-care (n=20) eye drops. The standard-of-care regimen consisted
of moxifloxacin ophthalmic solution dosed QID for 1 week, and nepafenac and prednisolone ophthalmic solutions dosed QID for 1 week, then tapered down by 1 daily dose each week
through 4 weeks. Patients were seen at 4 study visits: prior to surgery, and postoperative Days 1, 7, and 30. Change from baseline in OSDI was clinically significant in SYSTANE®
ULTRA + standard-of-care group5
‡ Preclinical study evaluating the effect of 6 artificial tear products (OPTIVE FUSION®, Allergan Limited; VISMED®, TRB Chemedica International SA; Thealoz Duo®, Thea
Pharmaceuticals Limited; Hyabak®, Thea Pharmaceuticals Limited; HYLO-COMOD®, URSAPHARM Arzneimittel GmbH; and Systane® HYDRATION, Alcon Laboratories Pty Ltd) on
re-epithelialization of a corneal debridement wound following topical ocular administration in mice. Sixteen mice were randomized 1:1 to each treatment group (96 mice total). The
epithelium of one cornea was debrided in each animal, and test solutions were administered every 2 hours after for a total of 4 administrations. To evaluate the number of re-epithelialized
corneas (fluorescein negative) in each treatment group 24 hours after debridement, corneas were stained with fluorescein, imaged, and analyzed to calculate the total
fluorescein-positive area. The difference in positive fluorescein pixels was statistically significant between Systane® HYDRATION vs OPTIVE FUSION® (p=0.0001), VISMED® (p=0.0001), Thealoz Duo® (p=0.0016), Hyabak® (p=0.0001), and HYLO-COMOD® (p=0.0369).7
