The current testing and treatment methodologies used in today’s healthcare system for dry eye sufferers are mostly intrusive or painful. Dry eye syndrome (also known as keratoconjunctivitis sicca) can occur when there is an imbalance in elements that are a part of normal vision. These include a healthy ocular surface where a sufficient quality of tears is coupled with a normal tear film, lid closure and regular blinking. The imbalance can casue a gret del of pain for the sufferer. More specifically, dry eye is a disorder of the tear film caused by tear deficiency or excessive tear evaporation. Testing for the disorder till now has been a exhausting process that is carried out in a laboratory environment which worsens the sufferer’s condition.
However, now there is a product invented by US company TearLab Corporation and developed by Invetech for fast and pain-free testing of the syndrome, which has bagged critical acclaim. The product allows testing to be carried out in record time and in an ophthalmologist’s surgery. It is a patented approach in which samples are collected from cornea of eyes through a handheld pen, which uses nanatechnology to collect just 50 nanolitres of tear samples, before using microfluidic technology and miniaturised electronics to provide a quantitative measurement. The measurement can then be viewed on a computer within seconds of transferring the data. This technology has been utilised to minimise the discomfort a patient undergoes. For the same reason the product has won a medical design excellence award and ensured positive feedback from healthcare experts around the world.
