Contact Lenses and Myopia (CLAM)

This study is now closed to enrollment.

Why we are doing this study:
We want to learn more about how multifocal contact lenses affect the way children focus their eyes and how their eyes work together.

Who can be in the study:

  • Patients 7 to 15 years of age.
  • Myopia (nearsightedness) between -1.00 and -8.00 D with <= 1.00 D astigmatism.
  • Able to see well in each eye with glasses or contact lenses.
  • Healthy with no history of eye disease or abnormal eye turns.

What the study involves:
There is only one visit that should take about two hours. During the visit we will:

  • Check the child’s vision
  • Examine the front of the child’s eyes
  • Have the child wear contact lenses
  • Ask the child to look at targets that are far away or up close while we do measurements to see how the child’s eyes focus and work together

Will you directly benefit from the study?
Being in this study won’t directly benefit you. It may help us learn more about the types of contact lenses that are being used to slow the development of nearsightedness.

Other things you should know about the study:

  • A parent will need to be present during the study visit.
  • You will receive $100 for your time to be in the study
