Abstract
PURPOSE:
Eyelid
changes have been reported with silicone hydrogel contact lenses. It is
hypothesized that those changes are associated with the mechanical interaction
between the contact lens front surface and eyelid tissues and, are specific to
contact lens type rather than a general effect of the lens category. The
purpose of this study was to assess the effect of refitting into a silicone
hydrogel on a daily wear basis to current contact lens wearers, lapsed wearers
and neophytes on eyelid physiology.
METHODS:
The
investigation was a 2-year prospective investigation of ACUVUE(®)
OASYS((R))with HYDRACLEAR(®)Plus (senofilcon A) used
with care systems, representative of current practice.
RESULTS:
90
subjects were enrolled of whom 64 subjects completed the investigation. The
results obtained were as follows:
CONCLUSIONS:
The
results of the study demonstrated that senofilcon A,
worn on a daily wear basis and replaced every 2 weeks, did not produce any
eyelid tissue changes in previous non-contact lens wearers at baseline and
revealed no change or a slight improvement of the eyelid tissues of established
contact lens wearers.
