  • Be able to wear the lens powers available for this study.
  • Be correctable to a visual acuity of 20/25 or better in each eye.
  • Have normal eyes with no evidence of abnormality or disease. For the purposes of this study a normal eye is defined as one having:
  • (i)No amblyopia. (ii) No evidence of lid abnormality or infection. (eg. entropion, ectropion, chalazia, recurrent styes). (iii) No clinically significant slit lamp (eg. any infiltrates or other slit lamp findings Grade 3 or above: corneal edema, corneal staining, tarsal abnormalities, conjunctival injection, vascularisation, or abnormal opacities).(iv) No other active ocular disease. (eg. glaucoma, history of recurrent corneal erosions, cornea infiltrates, conjunctiva, lids, and intraocular infection or inflammation of an allergic, bacterial, or viral etiology.)

Who cannot join

  • Requires concurrent ocular medication.
  • Any systemic illness which would contraindicate lens wear or the medical treatment of which would affect vision or successful lens wear.
  • No clinically significant (Grade 3 or 4) slit lamp findings including corneal edema, corneal vascularization, corneal staining, tarsal abnormalities, bulbar injection, or any other abnormality of the cornea that would contraindicate contact lens wear.
  • Diabetic.
  • Infectious disease (eg.hepatitis, tuberculosis)or an immunosuppressive disease (eg.HIV).
  • PMMA or RGP lens wear in the previous 8 weeks.
Show all 12Show fewer
  • Has had refractive surgery. Has had eye injury/surgery within 8 weeks immediately prior to enrollment for this study.
  • Abnormal lacrimal secretions.
  • Pre-existing ocular irritation that would preclude contact lens fitting.
  • Keratoconus or other corneal irregularity.
  • Pregnancy, lactating or planning a pregnancy at the time of enrollment only.
  • Participation in any concurrent clinical trial.

About this study

To evaluate the safety, efficacy and physiological performance of daily disposable spherical and toric soft contact lenses in a vision-corrected population of children ages 8-11 years of age. To evaluate the ability of the practitioner to fit these lenses and for the children to wear and manage these lenses.

Read the detailed description

This is a bilateral, open-label dispensing evaluation of two daily lens types. Eligible subjects will wear the study lenses for 3-months daily wear. 1-Day Acuvue will be worn by spherical subjects and 1-Day Acuvue for Astigmatism will be worn by astigmats.

There is a total of 4 study visits (baseline, contact fitting and dispensing, 1 week, 1 month and 3 month follow-up). Tests conducted include manifest refraction and over-refraction, keratometry, visual acuity, ACA ratio, lens fit assessment, slit lamp biomicroscopy and parent/patient questionaires.

Each child was provided with a supply of lenses to last until the next scheduled follow-up visit, unit-dose rewetting drops for rinsing their lenses if necessary, and a daily log to complete each day until the next follow-up visit.

Informed consent was obtained from all subjects after the nature of the study had been fully explained. The study gained approval from the Ethics Committee of the Singapore Eye Research Institute.

Questions about this trial

What is this clinical trial studying?

A study testing Johnson&Johnson Acuevue daily disposable lenses in people with Myopia, run by Singapore National Eye Centre at 1 site in Singapore.

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 10 inclusion and 12 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 12 May 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

i. demographics ii. refraction (D) visual acuity iii. AC/A Ratio (phorias in prism dioptres) iv. Keratometry v. Slit lamp examination vi. Corneal staining viii. Contact lens fit assessment (time frame: December 2006 to July 2007). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00473304, which also lists 3 linked publications.

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 12 May 2010.
