Understanding Dry Eye Disease and Treatment Goals
Dry eye disease (DED) is a common and often chronic condition where a person doesn't have enough quality tears to lubricate and nourish the eye. Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. For millions, this condition causes symptoms like a stinging or burning sensation, scratchiness, light sensitivity, and blurred vision. The disease is often categorized into two main types: aqueous deficient dry eye (not enough tears) and evaporative dry eye (tears dry up too quickly). Many people have a combination of both. The primary goal of prescription treatments like Miebo and Restasis is to go beyond the temporary relief of artificial tears and address the underlying causes of the disease.
Miebo (Perfluorohexyloctane): A New Approach to Evaporative Dry Eye
Miebo is the first and only prescription eye drop specifically designed to directly target tear evaporation. It is composed of 100% perfluorohexyloctane, a substance that forms a protective layer on the tear film. This action mimics the function of the natural lipid layer of the tears, which is often deficient in patients with Meibomian Gland Dysfunction (MGD), a leading cause of evaporative dry eye.
How Miebo Works
Upon instillation, Miebo spreads across the ocular surface, creating a monolayer that prevents the aqueous part of the tears from evaporating. By keeping more of your natural tears on the eye's surface for longer, it helps to improve the signs and symptoms of DED. Clinical trials showed that patients using Miebo experienced significant relief from eye dryness, with some noticing improvement as early as day 15. Because it is preservative-free and contains only a single ingredient, it is generally considered very comfortable upon application, with minimal stinging or burning.
Restasis (Cyclosporine): Targeting Inflammation to Boost Tear Production
Restasis has been a mainstay in DED treatment since its FDA approval in 2002. Its active ingredient, cyclosporine, is an immunomodulator that helps to increase the eyes' natural ability to produce tears. It is prescribed for patients whose tear production is presumed to be suppressed due to ocular inflammation associated with keratoconjunctivitis sicca (chronic dry eye).
How Restasis Works
Restasis targets the underlying inflammation that impairs the lacrimal glands' ability to produce tears. By reducing this inflammation, it helps your body to produce more of its own natural, healthy tears. This is a gradual process; it can take anywhere from 3 to 6 months for patients to experience the full therapeutic effect, although some may notice improvements sooner. Unlike Miebo, the most common side effect of Restasis is a temporary burning sensation upon instillation, which affects about 17% of users. A generic version of cyclosporine 0.05% is available, which can lower the cost.
Head-to-Head Comparison: Miebo vs. Restasis
Deciding if Miebo is more effective than Restasis depends heavily on the individual patient and the primary cause of their DED. As of late 2025, there are no direct, head-to-head clinical trials comparing the two medications. Therefore, effectiveness is judged based on their mechanisms, clinical trial data against a placebo, and patient-reported outcomes.

| Generic Available? | No. | Yes, for single-use vials. |
Conclusion: Which is Right for You?
There isn't a simple answer to whether Miebo is more effective than Restasis. The choice depends on the specific type of dry eye a person has.
-
Miebo may be a more effective option for individuals whose primary problem is evaporative dry eye, which is the case for a majority of DED sufferers. Its rapid onset of action and extremely low incidence of side effects like burning and stinging are significant advantages.
-
Restasis is a proven long-term therapy for those with inflammation-driven aqueous deficiency. For patients who need to increase their overall tear volume, and can tolerate the initial side effects and longer wait time for results, it remains a vital treatment option.
The significantly higher patient satisfaction ratings for Miebo suggest it is better tolerated and provides more consistent relief for many users. However, the best course of action is to consult with an eye care professional who can diagnose the specific cause of your dry eye and recommend the most appropriate therapy.
