Dry eye treatments compared: drops, heat masks, IPL and more

Gritty, burning, tired or even watery eyes are among the most common reasons people come to see us. Most have already tried a few things. Here is an honest look at the main dry eye treatments, what each one actually does, and why the right choice depends on what is causing your symptoms.

First, what is causing your dry eye?

Dry eye is not one condition. Broadly, there are two types, and many people have a mix of both:

• Evaporative dry eye. The tiny oil glands along your eyelids (the meibomian glands) become blocked or inflamed. Without enough oil, your tears evaporate too quickly. This is called meibomian gland dysfunction, or MGD, and it is the most common driver of dry eye: one large study found signs of MGD in around 86% of people with dry eye disease.
• Aqueous-deficient dry eye. The eyes do not produce enough of the watery part of the tears.

This matters because a treatment that helps one type may do little for the other. It is also why so many people end up using drops for years without feeling properly better.

The main treatments, from simplest to most advanced

1. Lubricating eye drops

Artificial tears are the usual first step, and for mild, occasional dryness they may be all you need. They top up the tear film and ease symptoms for a while. If you use drops more than a few times a day, preservative-free versions are generally kinder to the eye.

The limit: drops relieve symptoms but do not fix blocked glands. If you find yourself reaching for them every hour, that is a sign the cause needs looking at.

2. Warm compresses and heated eye masks

Warmth softens the thickened oil inside blocked meibomian glands so it can flow again. A warm flannel cools within a minute or two, which is why purpose-made heated masks tend to work better: they hold a steady temperature for the whole treatment, usually around ten minutes. The key is doing it regularly, not occasionally.

3. Eyelid hygiene

Cleaning along the lash line with a lid wipe or foam removes the build-up of oil, debris and bacteria that can keep glands blocked and cause blepharitis. In clinic, a deeper professional lid clean can clear what home cleaning cannot reach.

4. Screen and environment habits

We blink far less when we concentrate on a screen, so the tear film breaks up faster. Deliberate full blinks, regular breaks (look at something about 20 feet away for 20 seconds, every 20 minutes), keeping air vents away from your face and adding some humidity can all make a noticeable difference, especially for people who work at a computer all day.

5. Omega-3 supplements

Fish oil supplements are widely recommended online. However, a large, well-run trial (the DREAM study, published in 2018) found that omega-3 supplements were no more effective than a placebo for people with moderate to severe dry eye. Oily fish is still good for general health, but it is worth talking to us before spending money on supplements specifically for your eyes.

6. Prescription treatments

If inflammation is a significant factor, prescription options such as anti-inflammatory eye drops or a course of oral antibiotics can help in some cases. Depending on the treatment, these can be prescribed by an independent prescribing optometrist, your GP or an ophthalmologist.

7. In-clinic gland treatments, including OptiLight IPL

For evaporative dry eye caused by MGD, in-clinic treatments aim at the glands themselves:

• Meibomian gland expression: gently pressing the warmed glands to clear blocked oil.
• Thermal pulsation: devices that apply controlled heat and pressure to the eyelids.
• Intense pulsed light (IPL): precise pulses of light applied to the skin below the eyes, which help reduce the inflammation that keeps glands from working properly.

OptiLight by Lumenis is an IPL treatment authorised by the US Food and Drug Administration (FDA) in 2021 for improving the signs of dry eye disease due to MGD. It is used alongside other dry eye care rather than instead of it. A course is usually four short sessions, a few weeks apart, each followed by gland expression. Published studies of IPL for MGD have reported improvements in tear film stability and reductions in inflammatory markers in the tears. IPL is not suitable for everyone, for example some skin types and certain medical conditions, so an assessment comes first.

8. Red light and low-level light therapy

You may see red light masks or LLLT advertised for dry eye. This is a different technology from IPL. Early studies are encouraging, but the evidence base is smaller and less established so far.

9. Punctal plugs

For aqueous-deficient dry eye, tiny plugs placed in the tear drainage channels help your own tears stay on the eye for longer. They are less useful when the main problem is evaporation.

When to get your eyes assessed

It is worth booking a dry eye assessment if:

• your eyes feel dry, gritty or tired most days, despite using drops
• drops only help for an hour or so
• your eyes water a lot but still feel dry
• contact lenses become uncomfortable before the end of the day
• your eyelid edges are often red, crusty or swollen

A proper assessment looks at your tear film, your eyelids and your meibomian glands, so treatment can be matched to the cause rather than guessed.
