Overminus Lens Therapy for Children 3 to 10 Years of Age With Intermittent Exotropia

Abstract
Overminus lens therapy is a nonsurgical treatment option for childhood intermittent exotropia (IXT), in which an optical correction with more minus power than the cycloplegic refractive error is worn.1,2 Overminus lenses are typically used as a temporary treatment to improve control of IXT in young children before considering surgery3-7 or orthoptics.4,7 Some authors have reported success in maintaining good control and binocular function after gradually decreasing the strength of the overminus lenses over time and ultimately discontinuing the overminus lenses.5,6
