If you struggle with moderate to severe dry eye, you may have tried artificial tears with limited relief. When eye drops aren’t enough, your eye doctor may recommend Lacrisert® inserts - a prescription treatment designed to provide long-lasting moisture throughout the day. One of the most common questions patients ask is simple: how long do you leave Lacrisert inserts in?

Here’s what you need to know.

What Are Lacrisert Inserts?

Lacrisert inserts are small, clear rods made from a moisture-retaining material. Instead of delivering lubrication all at once like eye drops, the insert works gradually. After placement, it slowly breaks down and releases lubrication over many hours, helping keep the surface of the eye comfortable and protected.

Because it’s preservative-free and long-acting, Lacrisert is often recommended for patients with chronic dry eye who need more consistent relief.

How Long Should Lacrisert Stay in Your Eye?

Lacrisert inserts are designed to be worn all day.

Most patients place one insert per eye once daily, typically in the morning. The insert dissolves slowly over the course of the day and does not need to be removed. By the end of the day, it has usually dissolved completely on its own.

If any residue remains, it will continue to soften and break down naturally, so there’s no need to take it out manually unless your eye doctor specifically instructs you to do so.

When Should You Insert Lacrisert?

Lacrisert works best when inserted at the start of your day, before dryness becomes severe. Applying it early allows the insert to maintain moisture as your eyes are exposed to screens, air conditioning, wind, or contact lenses.

Your eye doctor may recommend a slightly different routine depending on your symptoms, so always follow their guidance.

What Does Lacrisert Feel Like?

When first inserted, some patients notice a brief sensation of something in the eye. This typically fades as the insert hydrates and softens. If discomfort continues, blurred vision persists, or the insert falls out repeatedly, contact your eye doctor—adjustments in technique or treatment may be needed.

Who Is a Good Candidate for Lacrisert?

Lacrisert is commonly prescribed for patients who:

• Have moderate to severe dry eye

• Don’t get enough relief from artificial tears alone

• Need long-lasting lubrication throughout the day

• Prefer a once-daily option instead of frequent eye drops

Your eye doctor will determine whether Lacrisert is appropriate based on your eye health, lifestyle, and severity of symptoms.
