Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to investigate the association of inflammatory mediators found in the tear film during the development and following the induction of contact lens solution-induced corneal staining.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Contact lens wearers

Contact lens wearers experienced three currently available contact lens/contact lens care combinations in randomized order: balafilcon A + Optifree RepleniSH, balafilcon A + ReNu MultiPlus, and balafilcon A + Unisol 4 saline.

Group Type EXPERIMENTAL

Opti-Free RepleniSH

Intervention Type DEVICE

Commercially available contact lens solution used for pre-soaking balafilcon A contact lenses overnight prior to lens insertion.

ReNu MultiPlus

Intervention Type DEVICE

Commercially available contact lens solution used for pre-soaking balafilcon A contact lenses overnight prior to lens insertion.

Balafilcon A

Intervention Type DEVICE

Commercially available silicone hydrogel contact lenses removed from blister pack and soaked overnight in Opti-Free Replenish, ReNu MultiPlus, or Unisol 4, then applied to the eye and worn for 2 hours.

Unisol 4

Intervention Type OTHER

Commercially available non preserved sterile saline solution used for pre-soaking balafilcon A contact lenses overnight prior to lens insertion.

Non-lens wearers

Non-lens wearers completed one study visit and served as the control group.

Group Type NO_INTERVENTION

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

For non-lens wearers:

* Normal eyes.
* Currently not wearing contact lenses and has not worn contact lenses for the previous 6 months.
* Free of dry eye using the Ocular Surface Disease Index (Schiffman et al).

For contact lens wearers:

* Currently wearing soft contact lenses.
* Free of dry eye during lens wear using the Contact Lens Dry Eye Questionnaire Short-Form (Nichols et al, Cornea, 2002).
* Reports a contact lens wearing time of at least 12 hours per day, 7 days per week, daily wear basis (not overnight wear).
* Reports only occasional use of contact lens rewetting drops or artificial tears.

Exclusion Criteria

For non-lens wearers and contact lens wearers:

* Pregnant.
* Participating in another research study.
* Exhibiting staining with fluorescein in more than 5% of the total cornea (graded by "extent" of staining across 5 regions).
