Wavelength Intervention for Nearsighted Kids

This study is looking into whether specialized soft contact lenses can help slow down nearsightedness (myopia) in children. Nearsightedness happens when the eye grows too long, and while glasses or contacts can fix blurry vision, they don't stop the eye from getting longer. This extra eye growth can lead to serious eye problems later in life. This study will compare two types of specialized soft contact lenses, called "specialized soft contact lens 1" and "specialized soft contact lens 2," to see if wearing them daily can slow down this eye growth. Researchers also want to understand how well children can wear these lenses and if there are any safety concerns. You might be able to join if you are between 7 and 12 years old, have a certain level of nearsightedness, and are willing to wear the lenses for at least 10 hours a day, six days a week.

Study design
This is an interventional study planning to enroll 80 participants. It is a randomized controlled clinical trial where participants will wear daily-use, daily-disposable soft contact lenses.
What's involved
Participants will wear specialized soft contact lenses for a minimum of 10 hours per day, at least six days a week, for one year. Measurements of refractive error and axial length will be taken at the start and after 12 months.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 12 months, with primary endpoints measured at baseline and 12 months.

Eligibility criteria

Inclusion

Spherical component of refractive error in primary meridian between -0.75 and -5.00 D
Less than 1.00 D of astigmatism or anisometropia
History of soft contact lens wear for at least a week
Best-corrected visual acuity of 20/25 (+0.10 logMAR) or better in each eye
Willingness to wear the lenses for a minimum of 10 hours/day, at least six days a week for the duration of the study

Exclusion

Subjects receiving myopia control treatments within the past six months
History of premature (less than 3.3 lb) or preterm birth (earlier than 30 weeks)
Current history of using systemic or ocular medications (including artificial tears) that may affect contact lens wear, tear film health, refractive state, pupillary response or accommodative function
History of ocular or systemic diseases, including those that may affect refractive development
Known allergy to fluorescein, benoxinate, proparacaine, or tropicamide
Contact lens contraindications (e.g., giant papillary keratoconjunctivitis)
Corneal disorders (e.g., hypoesthesia, keratoconus)
Strabismus at distance or near with distance glasses or contact lenses
Subjects exhibiting poor personal hygiene that may affect the compliance of contact lens wear.
  • Change in cycloplegic spherical equivalent refractive errorBaseline and 12 months

    Cycloplegic autorefraction measurements will be recorded using the WAM 5500 autorefractor in both eyes at baseline and follow-up visits. A set of 10 spherical equivalent measures will be obtained in each eye and later averaged to obtain the eye's final refractive error.

  • Change in axial lengthBaseline and 12 months

    Ocular component dimensions, including axial length, will be recorded using the Haag-Streit LenStar LS900 based on low-coherence interferometry. A set of five measurements in primary gaze in each eye will be averaged to obtain the final dimension of the ocular components.
