Improving contact lens comfort, especially when lens wear is associated with dry eye symptoms, is one of the most important issues that lens manufacturers and pharmaceutical companies as well as independent researchers have worked on for decades. A recently published report suggests that it could be, at least partially, solved with the use of hypo-osmotic saline eye drops.
Investigators from the Vision Cooperative Research Centre in Sydney, Australia, conducted a study evaluating the role of hypo-osmotic saline drops in lens comfort. They enrolled fifteen patients with contact lens discomfort issues, who subsequently wore AIR OPTIX NIGHT & DAY contact lenses for 6 hours, taking either hypo- or hyper-osmotic saline drops four times a day. The patients' symptoms and tear film parameters were assessed several times a day to check if the drops had a significant impact on them.
Hypo-osmotic saline drops improved the symptoms in about sixty per cent of the patients, decreasing dryness and lens awareness. However, the drops did not seem to affect tear film parameters.
The researchers concluded that hypo-osmotic saline eye drops can improve contact lens comfort in patients, but more research is needed to make definite recommendations.
