Posterior chamber intraocular lens implantation was effective for correcting refractive errors. More scientific studies about subjective visual quality(visual acuity, contrast sensitivity)and objective visual quality(wave front aberration, point spread function, Strehl ratio, modulmion transfer function)had showed that the improvement of subjective visual acuity was accompanied with the improvement of objective visual acuity after phakic intraocular lens implantation. However, the complications, such as anterior subcapsular cataract, glaucoma and decomposition of corneal endothelium needed to be long-term followed up. This article summarized the visual quality research after posterior chamber phakic intraocular lens implantation.
