No evidence to support a comfort difference between silicone hydrogel, hydrogel lenses
Closer conformity of the contact lenses to the bulbar conjunctiva improved wearers’ subjective comfort, according to researchers utilizing a PubMed search describing subjective comfort and contact lens material, fitting and design parameters.
Reduced lens movement or more contact lens tightness were associated with improved comfort, according to the study.
Also, increased lens-induced paralimbal conjunctival staining was associated with better comfort.
Researchers found “no evidence to support the perceived comfort difference between silicone hydrogel and hydrogel contact lenses,” they said.
They also found that lower equilibrium water content is associated with improved comfort in hydrogel contact lens wear.
“Refitting symptomatic wearers with an alternative contact lens material, design or replacement schedule may improve comfort, specifically considering edge design, lens movement and replacement schedule,” researchers wrote. – by Abigail Sutton
