Recent study showed eyedrops containing hyaluronic acid as opposed to just carboxymethylcellulose had greater retention on the corneal surface and appears to result in greater vision (Blythe Lindsay, Tamara Jones, Bridget O'Mahoney, Ben Browne*, Stuart Osborne*, Peter Chapman**, David LLoyd**, Clyde Wilson, Bio-Images Research, Ltd., Dep't of Ophthalmology, Gasgow Royal Infirmary, Optogenesis Europe, Dep't of Pharmaceutical Sciences, University of Strathclyde, Glaskow, UK.

One of the main characteristics of HA is its great hygroscopic capacity that allows retention of an amount of water up to 1,000 times its own weight.

Various studies have found that high-molecular-weight HA protects corneal epithelial cells against different types of damage, such as ultraviolet solar radiation.

High-molecular-weight HA has a reparative effect on the ocular surface, stimulating epithelial migration41,42 and inhibiting the expression of proinflammatory mediators such as interleukin (IL)-6 and IL-8.38

Therefore, a highly viscous solution has a higher ocular residence time and better contact of the product with the cornea and other ocular structures.
