Bifocal Lenses In Nearsighted Kids
Completed · Not applicable
Conditions studied: Refractive Errors
In brief
This study will evaluate the use of two different bifocal contact lens add powers to prevent further nearsighted progression in children ages 7 to 11 years old. It is theorized that the profile of the bifocal lenses will decrease the amount of change in nearsightedness that the children experience.

Who can join
Age: 7 and older, up to 11. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- 7 to 11 years, inclusive, at baseline examination
- -0.75 to -5.00 D, inclusive, spherical component, cycloplegic autorefraction
- ≤1.00 DC, cycloplegic autorefraction
- ≥ 2.00 D difference between the sphere components of the two eyes (anisometropia), cycloplegic autorefraction
- 0.1 logMAR or better best-corrected visual acuity in each eye
- 0.1 logMAR or better visual acuity OU distance and near with a +2.50 D add contact lens
- +2.50 D add lens provides adequate fit with respect to movement and centration
You may not qualify if…
- Eye disease or binocular vision problems (e.g., strabismus, amblyopia, oculomotor nerve palsies, corneal disease, etc.)
- Systemic disease that may affect vision, vision development, or contact lens wear (eg, diabetes, Down syndrome, etc.)
- Previous gas permeable, soft bifocal, or orthokeratology contact lens wear or bifocal/PAL spectacle wear (longer than 1 month of wear)
- Previous or current participation in myopia control studies
- Chronic use of medications that may affect immunity, such as oral or ophthalmic corticosteroids for ocular or systemic diseases
- Issues that may interfere with the ability to participate over the next 3 years
