Preservatives, which are designed to prevent contamination of eye drops during storage and use, can affect the natural tear film and damage the cells of the ocular surface. Furthermore, they can cause intolerance reactions¹. Modern ocular lubricants are therefore preservative free. This also applies to HYLO CARE® as it is provided in the patented COMOD® multi-dose device that, in a unique way, prevents contamination of its contents.
Phosphates that are widely used in eye drops can also have a harmful effect on an already damaged cornea². The binding of phosphate to calcium, which is released from damaged corneal cells, may lead to the formation of sparingly soluble calcifications that can permanently impair vision. Therefore, eye drops used on a dry and damaged ocular surface should not contain phosphates. HYLO CARE® is phosphate free and therefore presents no risk of corneal calcification.
