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 21 to 35 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • The subject must be male or female, of any race, and at least 21 years old and not older than 35 years old at the time of the pre-operative examination;
  • Both eyes must have a BSCVA of 20/20 or better;
  • Both eyes must have a manifest refractive error from -2.00 D to -6.00 D, a cylinder component up to -1.50 D, and a maximum manifest spherical equivalent of -6.00 D;
  • Both eyes must have at least 0.2 microns RMS HOA
  • Both eyes must have a minimum pupil size of at least 6.0mm in dim illumination on wavescan;
  • Both eyes must demonstrate refractive stability confirmed by clinical records or previous glasses. Refractive stability shall be documented by a change of less than or equal to 0.50 diopter (sphere and cylinder) at an exam at least 12 months prior to the baseline examination. The astigmatic axis must also be within 15 degrees for eyes with cylinder greater than 0.50 D; and
  • Subjects should be willing and capable of returning for follow-up examinations for the duration of the study.

Who cannot join

  • Use of systemic or ocular medications that may affect vision
  • Subjects who use concurrent topical or systemic medications that may impair healing, including but not limited to: antimetabolites, isotretinoin (Accutane®) within 6 months of treatment, and amiodarone hydrochloride (Cordarone®) within 12 months of treatment; NOTE: The use of topical or systemic corticosteroids, whether chronic or acute, is deemed to adversely affect healing and subjects using such medication are specifically excluded from eligibility.
  • Subjects with a history of any of the following medical conditions, or any other condition that could affect wound healing: collagen vascular disease, autoimmune disease, immunodeficiency diseases, ocular herpes zoster or simplex, endocrine disorders (including, but not limited to unstable thyroid disorders and diabetes), lupus, and rheumatoid arthritis; NOTE: The presence of diabetes (either type 1 or 2), regardless of disease duration, severity or control, will specifically exclude subjects from eligibility.
  • The subject must not have a history of prior intraocular or corneal surgery (including cataract extraction), active ophthalmic disease or abnormality (including, but not limited to, blepharitis, recurrent corneal erosion, dry eye syndrome, neovascularization > 1mm from limbus), clinically significant lens opacity, clinical evidence of trauma (including scarring), or with evidence of glaucoma or propensity for narrow angle glaucoma in either eye; NOTE: This includes any subject with open angle glaucoma, regardless of medication regimen or control.
  • Subjects who have Amblyopia or strabismus
  • Subjects with known pathology that may affect visual acuity; particularly retinal changes that affect vision (macular degeneration, cystoid macular edema, proliferative diabetic retinopathy, etc.)
Show all 14Show fewer
  • Subjects with diagnosed degenerative visual disorders (e.g. macular degeneration, or other retinal disorders) that are predicted to cause future acuity losses to a level of 20/30 or worse
  • Subjects who may be expected to require retinal laser treatment or other surgical intervention
  • Subjects with pupil abnormalities (non-reactive, tonic pupils, abnormally shaped pupils, or pupils that do not dilate at least 4.0 mm under mesopic/scotopic conditions)
  • Contact lens usage within 6 months for PMMA contacts lenses, 1 month for gas permeable lenses or 1 week for extended-wear and daily-wear soft contact lenses
  • Subject must not have any evidence of keratoconus, corneal irregularity, or abnormal videokeratography in either eye;
  • Subjects with known sensitivity or inappropriate responsiveness to any of the medications used in the post-operative course;
  • Patients who cannot obtain a Wavescan capture; and
  • patients seeking monovision.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing WAVEFRONT Optimized LASIK and WAVEFRONT GUIDED LASIK in people with Myopia, run by Innovative Medical at 1 site in United States.

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 7 inclusion and 14 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 14 Jun 2012. 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 United States. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Reduction or elimination of myopia and myopic astigmatism (time frame: 12 months). 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 14 Jun 2012.
