Artificial tears bring relief. But if you need them around the clock and are still uncomfortable, there is something more to treat.
Artificial tears are a very useful tool and, in mild cases, may be enough to maintain day-to-day comfort. They hydrate the surface of the eye and relieve the sensation of dryness, grittiness or stinging. The problem is that, in many cases, they act on the symptom rather than on the mechanism that causes it.
When meibomian gland dysfunction is present (the glands that produce the oily layer of the tear film), artificial tears can relieve symptoms but do not correct excessive evaporation — they are simply a replacement. For some patients they are sufficient; for others they need to be combined with eyelid hygiene, anti-inflammatory treatment or other measures targeting the underlying cause.
Before considering other treatments, it is worth remembering that artificial tears have no fixed dosage schedule. The frequency of instillation is adjusted according to the severity of dry eye. One, two or three drops a day may be insufficient for many patients diagnosed with dry eye. Evaporation affects not only the natural tear film but also the artificial one, although the hyaluronic acid that forms their main component helps to extend their stability. The recommendation: you can increase the frequency of drops until you find relief. Some patients reduce their symptoms to a minimum with drops every one to two hours, without any problems caused by the treatment. One important point: the drops should not contain preservatives.
If you need to use artificial tears very frequently, or continue to experience discomfort despite using them correctly, it is advisable to have an assessment to identify the predominant mechanism. This does not automatically mean you need intense pulsed light (IPL), thermal pulsation (LipiFlow) or another procedure: a precise diagnosis is what makes it possible to understand what is causing the dryness and which measures are best suited to your case.
This does not mean that artificial tears are abandoned. In many cases they continue to form part of the treatment, but alongside other measures, not as the sole solution.
It is also worth choosing the right type of eye drop. Preservative-free formulations are always preferable, to reduce the risk of toxic irritation of the ocular surface over time. This is also a choice worth discussing with a professional.
In summary: artificial tears are a good starting point and a valuable support, but if you need them continuously and are still not comfortable, it is time for an assessment to determine what type of dry eye you have and which treatment is best suited to your case.
