MIEBO is the First and Only Prescription Eye Drop that Directly Targets Tear Evaporation, the Leading Cause of Dry Eye Disease

Bausch + Lomb Corporation (NYSE/TSX: BLCO), a leading global eye health company dedicated to helping people see better to live better, today announced the U.S. commercial launch of MIEBO (perfluorohexyloctane ophthalmic solution) for the treatment of the signs and symptoms of dry eye disease (DED). MIEBO is the first and only prescription eye drop approved for DED that directly targets tear evaporation.

“More and more Americans are suffering from dry eye disease, due in large part to today’s multi-screen lifestyles,” said Andrew Stewart, president, Global Pharmaceuticals and International Consumer, Bausch + Lomb. “With MIEBO, eye care professionals now have a prescription eye drop that directly addresses tear evaporation, the leading cause of dry eye disease.”

DED affects more than 38 million Americans, with approximately nine in 10 experiencing evaporative dry eye.1,2 When not addressed, tear evaporation may lead to worsening of the condition by triggering a cycle of inflammation and ocular surface damage.3,4 MIEBO is a single ingredient, water-, preservative- and steroid-free prescription eye drop that spreads quickly and comfortably. It is designed to address the signs and symptoms of DED by reducing tear evaporation at the ocular surface.5-7

The U.S. Food and Drug Administration (FDA) approved MIEBO in May 2023, based on consistent results from two pivotal phase 3 trials. Its clinical development program includes the first and only phase 3 program for any FDA-approved prescription DED product composed entirely of patients with both DED and clinical signs of Meibomian gland dysfunction (MGD). MGD is a major cause of DED development and progression, with approximately 86% of people with DED having excessive tear evaporation associated with MGD.2 In the clinical trials, MIEBO delivered significant improvements in the signs and symptoms of DED and consistently met its primary clinical sign and patient-reported symptom endpoint. The most common adverse reactions experienced with MIEBO was blurred vision (1% to 3% of patients reported blurred vision and eye redness).

MIEBO™ (perfluorohexyloctane ophthalmic solution) is used to treat the signs and symptoms of dry eye disease.


  • Patients should remove contact lenses before using MIEBO and wait for at least 30 minutes before reinserting.
  • It is important for patients to use MIEBO exactly as prescribed.
  • It is not known if MIEBO is safe and effective in children under the age of 18.
  • The most common eye side effect seen in studies was blurred vision (1% to 3 % of patients reported blurred vision and eye redness).

Patients are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.

About Dry Eye Disease

DED is a chronic inflammatory ocular surface disease that is commonly characterized by dryness, stinging, burning, grittiness and/or episodes of blurred vision.8,9 The two main types of dry eye disease are aqueous deficient and evaporative. Aqueous-deficient dry eye occurs when the eyes do not produce enough tears. Evaporative dry eye is due to a deficient tear film lipid layer. The most common type of dry eye is evaporative.2

About MIEBO Phase 3 Clinical Trials

FDA approval of MIEBO was based on results from two 57-day, multi-center, randomized, double-masked saline-controlled studies, GOBI and MOJAVE. The studies assessed a total of 1,217 patients who received MIEBO or hypotonic saline (0.6%) in a 1:1 ratio.10,11

In these studies, MIEBO met both primary sign and symptom efficacy endpoints. The two primary endpoints were change from baseline at week eight (day 57 ± 2) in total corneal fluorescein staining (tCFS) and eye dryness Visual Analog Scale (VAS) score. Patients experienced relief of symptoms as early as day 15 and through day 57 with statistically significant reduction in VAS eye dryness score favoring MIEBO observed in both studies. Additionally, at days 15 and day 57, a significant reduction in tCFS favoring MIEBO was observed in both studies.

The most common adverse reactions experienced with MIEBO was blurred vision (1% to 3% of patients reported blurred vision and eye redness).
