New technique shows promise in restoring near vision without glasses
Date:3/31/2013

The new study shows that OK is similarly effective in changing corneal shape, and achieving desired correction in near vision, in older patients with presbyopia.

The new study suggests that overnight OK lenses are a feasible alternative for correction of presbyopia, "sufficient to provide functional near vision correction white retaining good distance visual acuity," Drs Gifford and Swarbick write. The technique is safe, with the cornea returning to its previous shape about a week after the patient stops wearing the lenses.

"This study demonstrates that OK is quite viable as a nonsurgical option for monovision that does not require wearing contact lenses during the day, although it does require 'retainer' orthokeratology contact lenses to be worn overnight," Dr Adams adds. "This possibility will certainly appeal to many people, especially since the changes in the corneal curvature of the treated eye are fully reversible."
