Hylo-Forte contains 0.2% Sodium Hyaluronate so has double the concentration of the active ingredient when compared to Hylo-Tear. In fact, it is 4 times thicker than Hylo-Tear so will last longer on the eye with minimal blurring. This makes it ideal for relieving the symptoms of severe dry eye. Delivered via the unique, patented, COMOD system, Hylo-Forte will release one drop for every click in a pump action technique. Hylo-Forte is preservative and phosphate free and will remain sterile for six months from the time of opening, making it economic and cost effective.
