Treatment of amblyopia by extended-wear occlusion soft contact lenses

Although occlusion eye patches are effective for the treatment of amblyopia, many physical difficulties arise such as allergic reactions of the skin and unattractiveness. Thus, in dealing with these problems we developed the occlusion extended-wear soft contact lens (OCL) to be used as a substitute for the eye patches. With these OCL, patients benefited from the 24-hour occlusion instead of the 6- or 8-hourly eye patch. Although there was a slight possibility that corneal problems might arise due to the lens, the amblyopia patients who gave up the eye patch treatment responded positively to the OCL treatment.
