What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the effectiveness of preservative-free eye drops for individuals with Dry Eye Syndrome, a condition causing discomfort and vision problems due to insufficient tear production. Participants will use these eye drops for a month to determine if they relieve symptoms. The trial seeks individuals diagnosed with Dry Eye Disease who have not found relief with hypertonic saline eye drops. As a Phase 4 trial, this research aims to understand how this already FDA-approved and effective treatment benefits more patients.

Will I have to stop taking my current medications?

The trial requires that you have not changed your medications in the last 3 months and do not anticipate any changes during the study. If you are using other topical treatments, you may need to stop them.

What is the safety track record for Preservative-free Refresh Optive Advanced Lubricant Eye Drops?

Research has shown that preservative-free Refresh Optive Advanced Lubricant Eye Drops are generally safe. Most users have reported only mild side effects, such as temporary blurred vision, a slight burning or stinging sensation, and minor irritation immediately after use. Some may also experience itching, redness, or watery eyes, but these effects typically resolve quickly.

The eye drops are available over the counter, indicating approval for general use and good tolerance by most individuals. Serious side effects are rarely reported. While minor discomfort may occur, the drops are considered safe for most people seeking relief from dry eye symptoms. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about preservative-free Refresh Optive Advanced Lubricant Eye Drops for dry eye syndrome because they offer a gentler alternative to many current treatments that contain preservatives, which can sometimes irritate sensitive eyes. Unlike other treatments that might rely on complex formulations or prescription-only access, these eye drops are available over the counter and are easy to use. Their preservative-free nature makes them a great option for people who experience irritation from other eye drops, potentially providing relief without additional discomfort.

What is the effectiveness track record for preservative-free Refresh Optive Advanced Lubricant Eye Drops in treating dry eye syndrome?

Research has shown that preservative-free Refresh Optive Advanced Lubricant Eye Drops effectively treat dry eye syndrome. Studies found that these eye drops significantly improved tear patterns, indicating increased eye moisture. Other research demonstrated that they increased the time it takes for tears to evaporate and reduced eye discomfort in people with dry eyes. The Optive Advanced formula also thickened the protective layer on the eye's surface, helping to maintain moisture. Overall, these eye drops consistently relieve dry eye symptoms by enhancing eye hydration and comfort. Participants in this trial will be divided into two groups: Hypertonic Saline Responders and Hypertonic Saline Non-responders, both receiving the same treatment with these eye drops. ^{6 7 8 9 10}

What Are the Treatments Tested in This Trial?

Interventions

• Preservative-free Refresh Optive Advanced Lubricant Eye Drops

Trial Overview

The trial is testing preservative-free Refresh Optive Advanced Lubricant Eye Drops on two groups: one that responds to hypertonic saline and one that doesn't. Participants will use the drops twice daily for four weeks and undergo questionnaires and eye tests before and after treatment.

How Is the Trial Designed?

Group I: Hypertonic Saline Responders Experimental Treatment 1 Intervention

Subjects who qualify as hypertonic saline responders will be instructed to instill 1-2 drops of preservative-free Refresh Optive Advanced Lubricant Eye Drops, which are available over the counter, into each eye twice a day for 28 days.

Group II: Hypertonic Saline Non-responders Experimental Treatment 1 Intervention

Subjects who qualify as hypertonic saline non-responders will be dispensed the same instructions and treatment as the Hypertonic Saline Responders. They will be instructed to instill 1-2 drops of preservative-free Refresh Optive Advanced Lubricant Eye Drops, which are available over the counter, into each eye twice a day for 28 days.

Published Research Related to This Trial

The study involving 45 contact lens wearers demonstrated that Systane Ultra Lubricant Eye Drops are safe to use, with no adverse events reported during the 14-day trial period.

Systane Ultra did not significantly affect visual acuity or corneal staining scores compared to a control solution, indicating its compatibility for contact lens wearers.

In a study of 60 patients with mild dry eyes, the lubricant eye drop containing polyethylene glycol 400 and sodium hyaluronate (Blink Intensive Tears) significantly reduced tear osmolarity compared to the other two tested drops, indicating better efficacy in improving eye moisture.

After 30 days of treatment, all lubricant eye drops improved tear osmolarity, but only Blink Intensive Tears showed a significant improvement in visual acuity, suggesting it may be the most effective option for treating dry, irritated eyes.

The study found that while all tested lubricant eye drops led to complete corneal healing by day 2, the Optive product caused progressive epithelial lesions by day 6, indicating potential corneal toxicity.

In contrast, Vismed Multi and Neopt did not adversely affect corneal integrity, suggesting they may be safer options for long-term use compared to Optive and Optive Fusion.

In a study of 50 participants with moderate ocular dryness, Systane(R) Lubricating Eye Drops significantly improved tear film break-up time (TFBUT) after 28 days of use, indicating better eye lubrication.

Participants reported significant relief from all six ocular discomfort symptoms, demonstrating both objective and subjective efficacy of Systane(R) in treating moderate ocular dryness.

The new benzalkonium chloride-free Visine® lubricant eye drop formulation (GentlePur™) was found to be very comfortable for both healthy and dry eye subjects, with comfort scores improving over the 14-day study period.

The eye drops demonstrated safety with no significant adverse events reported, and they effectively reduced corneal staining in dry eye subjects, indicating potential benefits for ocular health.

In a study involving 231 adults with lipid-deficient dry eye, Systane® Balance (SYSB) was found to be non-inferior to Refresh® Optive Advanced (RFO-Ad) in improving tear film breakup time (TFBUT) after 35 days of use, indicating similar efficacy between the two treatments.

Both eye drop treatments significantly improved TFBUT and reduced ocular discomfort, and were well tolerated by participants, suggesting they are safe options for managing lipid-deficient dry eye.

A new hydrophilic polymer insert has been introduced as an alternative therapy for patients with dry eyes due to practolol syndrome, showing subjective and objective benefits compared to traditional preservative-free drops.

In this open study, no patients experienced retention issues with the insert, indicating good tolerability, although some still preferred the soothing effects of frequent eye drops.

In a study involving 28 participants with dry eye disease, both lipid-based (Systane Complete) and non-lipid-based (Systane Ultra) artificial tears improved symptoms and tear film stability after application.

However, the lipid-containing eye drop showed superior benefits in preserving tear film quality and reducing dry eye symptoms after exposure to adverse conditions, indicating it may be more effective for managing dry eye disease.
