Introdução: Atualmente a utilização de lentes de contacto é muito comum, no entanto, um dos problemas mais comuns entre os usuários é a sensação de secura ocular que na maioria dos casos leva à sua intolerância e por seguinte à sua descontinuação. De forma a contornar o problema soluções de lágrima artificial são comummente aconselhadas. Este estudo tem como principal objetivo avaliar a influência das lágrimas artificiais no sistema visual de usuários de lentes de contacto.
Métodos: Para uma amostra de 15 indivíduos usuários de lentes de contacto (22,13±1,88 anos) testaram-se duas soluções de lágrima artificial. Para cada lágrima artificial foram necessárias três visitas, um total de seis. Os indivíduos foram instruídos a colocar uma gota de lágrima artificial em ambos os olhos três vezes ao dia. Em todas as visitas realizaram-se testes de avaliação de sintomatologia de secura ocular através do questionário OSDI, acuidade visual em alto e baixo contraste, aberrometria, tempo de rutura lacrimal não invasivo, altura do menisco lacrimal e avaliação do padrão lipídico.
Resultados: Não se registaram efeitos estatisticamente significativos com o uso das soluções de lágrima artificial na generalidade dos parâmetros, à exceção do tempo de rutura lacrimal não invasivo com o uso da lágrima artificial B (ácido hialurónico), onde se encontrou uma tendência para aumentar entre a 1ª e a 3ª visita (p=0,009).
Conclusão: Tendo em conta os resultados obtidos e comparando com estudos anteriores é possível concluir que as soluções de lágrima artificial não têm efeitos estatisticamente significativos em usuários de lentes de contacto com um filme lacrimal pré-lente aparentemente normal. Contudo, as lágrimas artificiais têm benefícios para os usuários de lentes de contacto sem sintomatologia de secura ocular nomeadamente preveni-la.
Introduction: Currently the usage of contact lenses is very common, however one of the biggest problems among users is the feeling of ocular dryness, which in most cases leads to its intolerance and, consequently, to its discontinuation. Artificial tear solutions are usually recommended as an answer to this problem. The main purpose of this study it’s to evaluate the influence of this tear solutions in the visual system of contact lenses users. Methods: For a sample of fifteen users of contact lenses (22,13±1,88 years) were tested two kinds of artificial tear solutions. For each artificial tear were necessary three appointments, so, six in total. The subjects were instructed to put one drop of the artificial tear in both eyes, three times a day. In every appointment it was evaluated the ocular dryness symptomatology through a OSDI quiz, the visual acuity in high and low contrast, wavefront analysis, non-invasive tear break up time, tear meniscus height and evaluation of the lipid pattern. Results: In general, it wasn’t registered any statistically significant results with both artificial tear solutions, with the exception of the non-invasive tear break time, which in artificial tear B (hyaluronic acid) increased between the 1st and 3rd appointment (p=0,009). Conclusion: Looking at the results and comparing them with previous studies it’s possible to see that the artificial tear solutions don’t have statistically significant results in the contact lenses users with an apparently ordinary pre-lens tear film. However, the artificial tears do have benefits for the contact lenses users without ocular dryness symptomatology since they help to prevent it.
