AIM: To compare the Pseudophakic accommodation of three monofocal intraocular lens implantation eye after phacoemulsification. METHODS: A total of 78 eyes from 78 patients under going phacoemulsification received intraocular lens based on the principle of voluntary. Twenty-three eyes from 23 patients who had implantation of AcrySof Natural intraocular lens were randomized into groupⅠ. Twenty-four eyes from 24 patients who had implantation of Canon staa intraocular lens were randomized into groupⅡ. Thirty-one eyes from 31 patients who had implantation of Canon staa intraocular lens were randomized into group Ⅲ. Main outcome measures included best-corrected distance visual acuity, distance corrected near vision, and the Pseudophakic accommodation amplitude. All the clinical data were obtained at 3 months postoperatively. RESULTS:At 3 months postoperatively, best-corrected distance visual acuity were similar among the 3 groups(F=0.317, P=0.729). Near vision on the basis of best corrected distance vision were statistically significant (F=3.377, P=0.039), added value on the basis of best-corrected near and the accommodation amplitude were statistically significant (F=10.094, P=0.000; F=16.806, P=0000) the among three groups. CONCLUSION: Three monofocal intraocular lens after cataract surgery implanted all could gain better distance visual acuity, near vision of the Acrysof Natural and the Canon staa intraocular lens implantation were more satisfactory, Acrysof Natural intraocular lens eyes had a better Pseudophakic accommodation.
