    Examining 7 options to control myopia

    New Orleans—As the prevalence of myopia is rapidly increasing throughout the world, myopia control has become a hot topic in optometry. Karen Lee, OD, FAAO, FSLS; Diana Nguyen, OD, FAAO; and Harue Marsden, OD, MS, FAAO, shared some options for myopia control in children during a session at the American Academy of Optometry annual meeting in New Orleans.


    1. Undercorrection

    “Back in the day, it was believed that undercorrecting our patients would keep them from getting worse,” says Dr. Lee.

    Studies, however, have found this not to be true. 

    One study of 62 children ages 6-15 in Israel found that those who had been blurred by +0.50 D experienced a slight increase in myopic progression of 0.17 D compared to those who had full correction.

    “It’s not preventing, it’s actually enhancing myopia,” says Dr. Lee.

    Similarly, a study of 106 Malay and Chinese children ages 9-14 years found that those who were blurred by +0.75 D also experienced a slight increase in myopic progression of 0.23 D compared to full correction.

    2. Bifocals

    “A method that is slightly more effective is bifocals,” says Dr. Nguyen.

    The presenters highlighted an 18-month study of 14 children in which the bifocal wearers with a +1.25 D add progressed -0.39 D per year vs. -0.57 D per year in the single-vision lens group.

    “It sounds like it’s a significant amount, but it’s not a clinically significant amount because if you round the numbers to the nearest 0.25 D, it’s about 0.50—very similar there,” says Dr. Nguyen.


    3. PALs

    In the COMET 2 study, 8 to 11 year-old children used progressive addition lenses (PALs) with a +2.00 D add. These children experienced -0.87 D myopic progression vs. -1.15 D in the single-vision lens group.

    Dr. Lee says the difference was not very significant.
