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.

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.

The spherical refractive errors and the cylindrical refractive errors showed statistically significant results ( p < 0.05). The lower was the refractive error, the greater were the UVA and IVA results. Correlations existed between the corneal astigmatism and UVA or IVA at three months ( p < 0.05). The lower was the corneal astigmatism, the greater were the UVA and IVA results. Correlations were observed between the initial visual acuity and IVA, although the initial visual acuity cannot be a predictor. The other factors evaluated did not show statistically significant results ( p > 0.05).

The refractive error and the corneal astigmatism may be strong predictors of UVA and IVA after RGL use.
