The most common complaint is dryness—particularly among patients who are unable to wear their lenses for a full day and those who are at high risk for dropping out of lens wear.2

While it is the presence of silicone in silicone hydrogels which facilitates the extraordinary level of gas exchange, at the same time it also confers a hydrophobic nature to the material.3 To overcome this, manufacturers employ a variety of techniques to transform the contact lens into one that is compatible with the moisture-requiring environment of the ocular surface. These inclu...
