In a study of 28 children with at least 6.00 D of myopia, partial reduction orthokeratology resulted in a 4.50-D median reduction of myopia in the treatment group.

“The results of this study represent a big leap in alternatives for high myopes,” study co-author Jessie Charm, MPhil, said in an article published in the August print edition of Primary Care Optometry News.

According to the study published in Optometry and Vision Science, 12 children in the treatment group were fitted with custom-made four-zone ortho-K lenses with a target reduction of 4.00 D for both eyes. After 2 years, in addition to the reduction in myopia, there was a mean increase in axial length of 0.19 mm in the partial reduction ortho-K group and 0.51 mm in the control group.

“Slowing axial elongation can help to reduce potentially sight-threatening complications, such as retinal detachment, macular degeneration or glaucoma,” Charm said.
