Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 20 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Subjects should have normal eyes and use no ocular medications. They may have worn contact lenses previously, provided their eyes are shown to be normal at the start of the investigation. A normal eye is defined as having the following characteristics:
- No anterior segment infection, inflammation or abnormality.
- No other active ocular or systemic disease that would contraindicate contact lens wear; and
- No medications that would contraindicate contact lens wear.
- VA correctable to 0.1 LogMAR or better, with spherical lenses ranging in power from
- 1.00 to -10.00 D myopia, astigmatism less than 2.00 D
- Willing to comply with all study procedures and be available for the duration of the study.
- Provide signed and dated informed consent form.
Who cannot join
- Have history of allergies that would contraindicate "normal" contact lens wear.
- Have other active ocular or systemic disease such as, but not limited to: anterior uveitis (past or present), glaucoma, Sjögren's syndrome, lupus erythematosus, sclerodermas, keratoconus or type II diabetes, slip lamp findings greater than grade I (such as cornea or interstitial edema).
- Have medications that would contraindicate contact lens wear.
- Have had any cornea surgery.
- Currently pregnant (to the best of the subject's knowledge), is lactating or is planning a pregnancy within the next 1 month.
- Any active participation in another clinical trial within 30 days prior to this study.

- The presence of clinically significant (grade 3 or 4) anterior segment abnormalities; inflammations such as iritis; or any infection of the eye, lids, or associated structures.
- A known history of corneal hypoesthesia (reduced corneal sensitivity), corneal ulcer, corneal infiltrates or fungal infections.
- A history of papillary conjunctivitis that has interfered with contact lens wear.
- No monocular or monovision fits.
- Alcoholic or Drug Abused.
About this study
Official title: A Prospective Randomized Controlled Study to Evaluate the Clinical Performance of OxyAqua Silicone Hydrogel Soft Contact Lens
The objective of this study is to demonstrate that the OxyAqua silicone hydrogel soft contact lens could be prescribed as a supportive care for myopes.
Read the detailed description
This is a double blind randomized control study to evaluate a daily disposable contact lens. It is planned to have 30 evaluable subjects at least divided evenly among 3 independent PIs from one hospital. Each PI will enroll 12 subjects at least. The ration of evaluable test subjects to control subjects will be 2 to 1. The study lens will be dispensed randomly to subjects who have normal ocular health and conform to a set of criteria. It is necessary to wear the lens 8 hours a day and 5 days a week at least and follow up for one month (30 days). Data will be collected at baseline, 1 week, 2 week and 4 week of daily disposable modality including Adverse Reactions, Slit-lamp findings and Symptoms, Problems, and Complaints, vision acuity, keratometry change and reason for discontinuation.

Measured: one month
Secondary outcomes (2)
Any slit lamp findings > grade 2
slit lamp findings on all dispensed eyes over all follow-up visits. Measured on a scale of 0-4 with 0=no findings and 4=sever findings.
Measured: over all follow-up visits for the 1 month
Subjective response to comfort, symptoms and complaints
subjective ratings of comfort, symptom and complaints using a scale of 0=severe stinging/Burning to 5=No stinging/Burning for each eye
Measured: over all follow-up visits for the 1 month

What is this clinical trial studying?
A study testing OxyAqua and Si-Hy in people with Myopia, run by Visco Vision Inc..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 May 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Log MAR visual acuity (VA) (time frame: one month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 May 2017.
