Overall performance of the Safegel 1 day lens.

The article presents a study which examined the performance of Safegel 1 day contact lenses. The researcher concluded that the principal approaches to improving lens comfort and the symptoms associated with dryness are maintaining hydration and making the lens as lubricious as possible, and using additives in the lens blister or within the lens matrix. The range of Safegel lenses takes the latter approach with the slow release of sodium hyaluronate into the tear film during wear.
