Evaluation of Disinfecting Solutions and Protein Remover With a Silicone Hydrogel Lens
A study testing Alcon Opti-Free® RepleniSH® with Supraclens®, Alcon Opti-Free® RepleniSH® and B&L ReNu MultiPlus™ in people with Ametropia, run by University of Waterloo at 1 site in Canada.
Trial summary
The purpose of this study is to determine if reduced lens deposits and increased comfort can be achieved by using Multipurpose disinfecting solutions (MPDS) in a no-rub format but in conjunction with an intensive cleaner, rather than using MPDS in a rub format. Read more about this study

What is being measured
The primary outcome is the main question the study is designed to answer.
Comfort
Subjective comfort ratings on analog scale (0= very poor comfort; 100= excellent comfort), self report by subject based on single criterion 'comfort'.
Measured: 4 weeks
Lens Wettability
Subjective grading of contact lens surface wettability by investigator (0=excellent; 4=severely reduced).
Measured: 4 weeks
Lens Deposits
Subjective grading of contact lens surface deposits by investigator (0=no deposits; 4=severe deposits).
Measured: 4 weeks
Secondary outcomes (3)
Dryness
Subjective dryness ratings on analog scale (0= very dry; 100= not dry at all), self report by subject based on single criterion 'dryness'.
Measured: 4 weeks
Subjective Vision
Subjective vision ratings on analog scale (0= poor vision; 100= excellent vision), self report by subject based on single criterion 'vision'.
Measured: 4 weeks
Corneal Staining
Grading based on Type (0=None; 100=patch)and extent of staining (0=None; 100= Entire corneal region). Final value is Type multiplied by Extent.
Corneal staining is a test that uses an orange dye (fluorescein) and a blue light to detect damage to the cornea (front surface of eye) from minor abrasions.
A strip of blotting paper containing the dye was touched to the eyelid margin. Upon blinking, the dye spreads and coats the front surface of the eye along with the tear film covering the surface of the cornea. The investigator then rated the size, location and shape of the staining.
Measured: 4 weeks
