Successful Treatment of Refractive Anisometropia with Prismatic Progressive Additional Lenses: A Technical Report

Li-Ju Lai and Wei-Hsiu Hsu

Background: Anisometropia was a challenge for ophthalmologists to treat unilateral refraction condition. Failure of build-up the same clear image from two eyes together was the major cause for quitting spectacle wearing, which usually led to amblyopia in the eye with more myope.
Case presentation: The two patients with anisometropia were found that the two eyeballs position were
asymmetric by photography (RTV, Carl Ziess Meditec, Co). Binocular visual acuity was analyzed by using polarized lens in the both eyes for stereo-acuity in far vision (Polatest, Carl Zeiss, Germany) by following the guidelines from the Internationale Vereinigung for Binokulare Vollkorrektion (IVBV). Binocular vision was corrected by the stereoacuity in the far vision, and prism measurement was done by subjective opinion from the patient.
Conclusion: Asymmetric eyeball position and size are the risk of anisometropia progression. Under the
guidelines from MKH (Measuring and correcting Methodology after H.J-. Haase) for correction of associated phoria, the vision was corrected not only in the spherical and cylinder amount but also in binocular full-correction. Prism improved in binocular vision function in the far vision. By using the prismatic progressive additional lenses, the unilateral myopia progression was well controlled after followed for 4 years.
