Dry eye is one of the most common side effects of isotretinoin (Accutane). Clinical data indicates that approximately 30% to 50% of patients taking the medication experience significant eye dryness. Some studies suggest the number is even higher for specific symptoms, with nearly 90% of wearers reporting intolerance to their contact lenses during the course of treatment.

Unfortunately, the drug does not distinguish between the oil glands on your face and the oil glands in your eyelids, known as Meibomian glands. Research shows that the medication causes these vital eye glands to shrink and produce less oil. This creates a "tear film instability," where the tears evaporate too quickly because they lack the protective oil layer.
For many patients, the dryness resolves a few weeks after stopping the medication. But for a significant number of users, the structural damage to the glands is permanent. Studies using infrared meibography (imaging of the glands) have shown that isotretinoin can cause gland atrophy or "dropout," meaning the glands physically disappear. Once a Meibomian gland dies, it cannot grow back, leading to lifelong dry eye disease.
The severity of the side effects is often dose-dependent. Patients on high daily doses generally experience more severe gland suppression than those on "low-dose" regimens. The total cumulative dose also matters. The longer a patient stays on the drug, the more time the glands have to degrade. Doctors often monitor eye comfort as a sign of whether the dosage needs to be lowered to protect the glands.
Because of the lack of oil, the friction between the eyelid and the eye increases. This makes wearing contact lenses painful or impossible. Data shows that the majority of contact lens wearers have to switch to glasses during treatment. Attempting to force lens wear during this time can lead to corneal abrasions and severe infections.
Artificial tears help with symptoms, but they do not stop the drug from shrinking the glands. Using preservative-free drops frequently is necessary to prevent corneal damage while on the medication.
Yes. Isotretinoin can affect the retina's ability to process light in the dark. About 10% of users report decreased night vision (nyctalopia), which can persist even after therapy ends.
You should consult your prescribing doctor immediately. If the dryness is severe, they may lower the dose or stop the treatment to prevent irreversible damage to your tear glands.
If you are considering Accutane, it is smart to have an eye exam before starting to map your Meibomian glands. During treatment, if you feel constant grittiness, burning, or light sensitivity, see an eye doctor. They can prescribe prescription eye drops or perform in-office treatments to help keep the oil glands flowing and reduce the risk of permanent atrophy.
