Physiological accommodation in aphakia has been reported 0.50D. Also, accommodation appears in pseudo-crystalline lens. However accommodation was not clear how to works in the eyes. Therefore, the purpose of this study is that accommodation has been affected to changes of axial length and corneal refractive power when the accommodative stimulus was taken 10 diopters to person who has pseudo-crystalline lens. To determine of the accommodative response of pseudo-phakic patients who had no side effects over 2 months, we have measured the axial length, corneal refractive power in 48 patients(96 eyes). When the accommodative stimulus was taken about 10 diopters, the axial length increased by $0.05{pm}0.06mm$ and corneal refractive power increased $0.04{pm}0.24$ diopter. The changes of axial length in the myopia was increased by $0.19{pm}0.18D$, emmetropia was increased by $0.12{pm}0.16D$ and hyperopia was $0.10{pm}0.19D$. The results of measurement revealed that the mean value was increased $0.03{pm}0.13D$ in the myopia, and increased $0.21{pm}0.13D$ in the emmetropia, and decreased $0.02{pm}0.34D$ in the hyperopia.
