The Influence of Factors Before Wearing Reverse-Geometry Lens on Visual Acuity After Wearing Reverse-Geometry Lens

ABSTRACT

PURPOSE: To determine whether patient factors (pre-fitting patient's data) before reverse-geometry lens (RGL) use could be predicting factors for the increase in visual acuity after RGL use. METHODS: The authors reviewed out patient records of 805 eyes of 423 patients wearing RGLs from March 2003 to May 2009. The relationship between patient factors on UVA before wearing a RGL examined at follow-ups and the IVA after wearing a RGL were analyzed. RESULTS: The spherical refractive errors and the cylindrical refractive errors showed statistically significant results (p 0.05). CONCLUSIONS: The refractive error and the corneal astigmatism may be strong predictors of UVA and IVA after RGL use.
