Understanding Lacriserts and What They Treat
A Lacrisert is a tiny rod-shaped insert made from hydroxypropyl cellulose. Unlike eye drops that you apply multiple times each day, you place one insert in the lower eyelid where it stays and gradually dissolves. This gives you steady relief without the need to remember frequent dosing.
Eye drops provide quick moisture but wash away in minutes, while Lacriserts work continuously for many hours. The insert sits in the space between your lower eyelid and eyeball, releasing its ingredients slowly as your natural tears dissolve it.
Hydroxypropyl cellulose is a clear substance that absorbs water and forms a protective gel on your eye surface. As the insert dissolves, this gel mixes with your natural tears to create a thicker, longer-lasting tear film. The thicker layer helps prevent evaporation and keeps your cornea moist.
This ingredient is safe and well tolerated by most people. It does not contain preservatives, which makes it a good choice if you are sensitive to the chemicals found in many bottled eye drops.
We may suggest Lacriserts if you have moderate to severe dry eye that does not improve with standard artificial tears. They can be especially helpful if you need to use drops very frequently throughout the day or if you have trouble remembering to use drops often enough. Lacriserts can also benefit people whose tear glands do not produce enough natural moisture.
Some patients prefer the convenience of a single daily insertion rather than carrying bottles and applying drops every hour. We evaluate your specific dry eye causes and lifestyle to decide if this treatment fits your needs.
Most people get relief for twelve to twenty-four hours from one Lacrisert. The exact duration depends on your tear production and how quickly the insert dissolves in your eye. Some patients notice the effect lasting through an entire day and into the evening.
You typically insert one Lacrisert once daily, usually in the morning. If your dry eye is very severe, we may recommend using one in each eye or adjusting the timing based on when your symptoms are worst.
Signs You May Need Lacriserts
Moderate to severe dry eye often causes burning, stinging, or gritty feelings that persist throughout the day. You may experience blurred vision that improves when you blink, heavy or tired eyelids, or eyes that water excessively as your body tries to compensate for dryness. These symptoms can interfere with reading, computer work, and driving.
If you wake up with stuck eyelids or notice thick discharge, your tear film may not be protecting your eyes properly overnight. Redness and sensitivity to light or wind are also common signs that your dry eye is more than mild.
You may need stronger treatment if you find yourself using artificial tears more than four to six times per day with little improvement. Frequent use can actually wash away your natural tears and make symptoms worse. If you wake up during the night to apply drops, your dry eye likely needs a longer-lasting solution.
Some people develop irritation from preservatives in bottled tears, which limits how often they can safely use drops. Lacriserts provide an alternative that delivers continuous moisture without preservatives or the need for repeated application.
Lacriserts can help manage dry eye related to Sjogren syndrome, a condition where your immune system attacks moisture-producing glands. They are also useful for people with exposure keratitis, where the eyelids do not close completely and leave the cornea exposed to air. Other conditions include tear deficiency from aging, medications, or environmental factors.
We may consider Lacriserts if you have had eye surgery that reduced your tear production or if you have scarring on the eye surface that affects how tears spread. Each situation requires careful evaluation to determine if Lacriserts are appropriate.
Seek care right away if you experience sudden vision loss, severe eye pain, or discharge that is yellow or green and thick. These symptoms may indicate an infection or other urgent problem that needs immediate treatment. Flashes of light, new floaters, or a curtain across your vision are also emergency signs.
If you have severe redness that worsens quickly, a feeling that something is stuck in your eye that does not go away, or eye pain after an injury, contact us or visit an emergency eye care provider. Do not wait to see if these symptoms improve on their own.
Evaluation and Getting a Prescription for Lacriserts
We begin by asking about your symptoms, when they occur, and what makes them better or worse. We will review your medical history and any medications you take, since many drugs can reduce tear production. We also ask about your work environment, screen time, and hobbies that might contribute to dry eye.
Next, we examine your eyelids and the surface of your eyes using a special microscope called a slit lamp. This allows us to see inflammation, irritation, and how well your tear film covers your cornea. We look for signs of damage to the eye surface that may need treatment.
The Schirmer test measures how much tears your eyes produce. We place a small strip of paper inside your lower eyelid and wait five minutes to see how much the strip wets. Low values suggest that your eyes do not make enough natural tears. This simple test helps us understand the severity of your dry eye.
- Tear breakup time measures how long your tear film stays stable before evaporating
- Corneal staining uses a dye to highlight dry spots or damage on your eye surface
- Meibomian gland evaluation checks if your oil glands are working properly
- Osmolarity testing measures the salt concentration in your tears, which rises when you have dry eye
We recommend Lacriserts when test results show low tear production and your symptoms have not improved with simpler treatments. We consider your ability to insert the product correctly and your willingness to use it daily. Lacriserts work best for people who can follow the insertion routine and who need continuous moisture rather than occasional relief.
We also think about any other eye conditions you have and whether Lacriserts might help or interfere with those treatments. If you take several eye medications, we plan how to space them so everything works well together. Cost and insurance coverage are practical factors we discuss before prescribing.
Ask how often you should insert Lacriserts and what time of day works best. Find out what to do if the insert falls out or if you experience side effects. It is helpful to know how long you should try Lacriserts before deciding if they are working for you.
You should also ask whether you need to stop or adjust any current eye drops, and whether Lacriserts are safe to use with your other medications. We encourage you to discuss any concerns about insertion technique so we can show you the proper method.
How to Insert and Use Lacriserts Correctly
Wash your hands thoroughly with soap and water before touching the insert or your eye. Make sure your hands are completely dry to avoid dropping the small insert. Remove the Lacrisert from its package carefully, touching only the edges to keep it clean.
Stand or sit in front of a mirror in good lighting so you can see what you are doing. Have a clean tissue nearby in case you need it. If you wear contact lenses, remove them before inserting a Lacrisert.
Tilt your head back and look up toward the ceiling. Gently pull your lower eyelid down with one finger to create a small pocket between the lid and your eyeball. Use your other hand to place the Lacrisert into this pocket, positioning it under the lower lid as far from the center of your eye as comfortable.
- Do not place the insert directly on your cornea or pupil
- Release your lower lid slowly and blink gently to settle the insert
- The insert should sit in the lower cul-de-sac without irritating your eye
- If the insert is visible or uncomfortable, gently adjust its position with a clean finger
Insert one Lacrisert at the same time each day to build a routine you will remember. Many people find morning insertion works well because the insert can then provide relief throughout the day. Keep your Lacriserts at room temperature and away from moisture until you are ready to use them.
Check your eye in the mirror after insertion to make sure the insert is in place. If you notice it has moved to a visible spot on your eye, you can use a clean fingertip to gently push it back into the lower pocket. Do not reuse an insert that has fallen out or been removed.
You may notice a slight awareness of the insert for the first few minutes, similar to having a small particle in your eye. This feeling usually goes away as the insert begins to dissolve and your eye adjusts. Some people experience temporary blurred vision right after insertion, which clears as the insert settles and starts to work.
Your eye may produce extra tears for a short time after you insert the Lacrisert. This is a normal reaction and should decrease quickly. If discomfort lasts more than an hour or gets worse, the insert may not be positioned correctly.
If a Lacrisert falls out within the first few hours, you can insert a new one if you have extras available. Do not try to reuse the one that fell out, as it may no longer be sterile. Inserts sometimes fall out if they are not placed far enough back in the lower lid pocket or if you rub your eyes.
Frequent loss of inserts may mean you need to adjust your technique. We can watch you insert a Lacrisert during an office visit and give you tips to improve placement. If inserts continue to fall out despite correct technique, Lacriserts may not be the best option for you.
Side Effects and What to Expect While Using Lacriserts
Blurred vision for ten to thirty minutes after insertion is common and usually not a cause for concern. The insert creates a gel that temporarily changes how light enters your eye. Blinking several times helps the gel spread evenly and can speed up clearing of your vision.
Plan your insertion time so you do not need to drive or do detailed tasks right away. If blurred vision lasts longer than an hour or happens every time you insert a Lacrisert, let us know. We may suggest adjusting the insertion time or trying a different dry eye treatment.
Some people notice watery eyes or excess tearing after inserting a Lacrisert. This happens because the insert can stimulate your eye to produce more tears, especially when you first start using it. The extra tearing often decreases after a few days as your eye gets used to the insert.
If watery eyes continue or interfere with your vision, we may adjust your treatment plan. Excessive tearing combined with ongoing dryness can indicate that your dry eye has multiple causes that need different approaches.
Feeling like something is in your eye is possible, particularly during the first week of use. This sensation should be mild and improve as the insert dissolves. If the feeling is sharp or painful, the insert may be positioned incorrectly or your eye may be reacting to it.
A foreign body sensation that persists beyond the first week might mean Lacriserts are not right for you. We can evaluate whether the insert is causing irritation or if an underlying eye surface problem needs treatment first.
Contact us if you develop severe pain, vision changes that do not clear, or redness that gets worse over time. These symptoms may signal an infection, allergic reaction, or damage to the eye surface. Discharge that is thick and colored, especially with crusting on the eyelids, also needs prompt evaluation.
Swelling of the eyelid, a rash around the eye, or itching that spreads beyond the eye area can indicate an allergy to the insert material. Stop using Lacriserts and reach out to our office so we can examine you and recommend a different treatment if needed.
If mild side effects continue after the first two weeks, we may suggest changing when you insert the Lacrisert or trying a different position in the lower lid. Some people do better with evening insertion if morning use interferes with work or other activities. We work with you to find a schedule that minimizes side effects.
In some cases, we may reduce the frequency of insertion or combine Lacriserts with other treatments to improve comfort. If side effects do not improve with adjustments, we will discuss alternative dry eye therapies that may work better for your situation.
Combining Lacriserts with Other Dry Eye Treatments
You can use preservative-free artificial tears with Lacriserts if you need extra moisture during the day. Wait at least ten to fifteen minutes after inserting the Lacrisert before applying drops so the insert has time to settle. This prevents the drops from washing the insert out of position.
Choose preservative-free tears to avoid irritation from chemicals that can build up on your eye surface. Many people find they need fewer drops once Lacriserts start working, but you can use them as needed for additional comfort.
We may prescribe anti-inflammatory drops such as cyclosporine or lifitegrast if your dry eye involves inflammation. These medications address the underlying immune response that damages your tear glands and eye surface. They work well with Lacriserts because they target different aspects of dry eye disease.
Apply prescription drops at a different time than you insert your Lacrisert, spacing them by at least fifteen minutes. This ensures each medication has time to absorb properly. We will give you a schedule that fits all your treatments into your daily routine without conflicts.
Punctal plugs are tiny devices we insert into the drainage holes in your eyelids to keep natural tears on your eye longer. They can be used together with Lacriserts to maximize moisture retention. This combination is helpful if your eyes both under-produce tears and drain them too quickly.
Other in-office treatments such as intense pulsed light therapy or meibomian gland expression may address problems with the oil layer of your tears. We customize your treatment plan based on which parts of your tear system need support.
Simple changes can boost the effectiveness of Lacriserts. Taking regular breaks from screens using the 20-20-20 rule reduces eye strain and helps you blink more often. A humidifier in dry indoor environments adds moisture to the air and slows tear evaporation.
- Drink plenty of water throughout the day to support overall hydration
- Eat foods rich in omega-3 fatty acids, which may improve tear quality
- Protect your eyes from wind and sun with wraparound sunglasses
- Avoid smoke and limit exposure to air conditioning or heating vents aimed at your face
We schedule follow-up visits to check how well Lacriserts are working and whether you need changes to your regimen. If your symptoms improve significantly, we might be able to reduce other treatments. If dry eye remains a problem, we may add therapies or explore different underlying causes.
Your treatment plan should evolve based on how your eyes respond and any changes in your health or lifestyle. Regular monitoring helps us catch problems early and keep your eyes as comfortable as possible.
Frequently Asked Questions
Most patients insert one Lacrisert once daily, typically in the morning. Because each insert dissolves slowly over twelve to twenty-four hours, a single application usually provides relief all day. If your dry eye is extremely severe, we may recommend inserting one in each eye or occasionally using a second insert later in the day, but this is decided on a case-by-case basis during your follow-up appointments.
Lacriserts are generally not recommended for use while wearing contact lenses. The insert can interact with the lens and cause discomfort or affect how the lens sits on your eye. If you need both vision correction and Lacriserts, we suggest switching to glasses during treatment or discussing specialty contact lenses designed for dry eye that might work better with your moisture needs.
Lacriserts are considered safe for extended use in patients who need ongoing dry eye management. Because they contain no preservatives and use a gentle, biocompatible ingredient, long-term daily use typically does not harm the eye surface. We monitor you regularly to ensure they continue to work well and to watch for any changes in your eye health that might require adjusting your treatment approach.
If you miss a dose, insert a Lacrisert as soon as you remember, unless it is almost time for your next scheduled insertion. Do not double up by inserting two at once to make up for a missed dose. You may notice your dry eye symptoms returning until the next insert starts working. Keeping your Lacriserts in a visible spot or setting a daily reminder can help you remember your routine.
Lacriserts usually do not interfere with other eye medications when used correctly. The key is to space out your treatments so each one has time to work without washing away the others. We provide a schedule that staggers drops and insert placement by at least ten to fifteen minutes. Always tell us about every eye medication and supplement you use so we can check for interactions and plan the best timing for everything.
