title: [The clinical efficacy of accommodative intraocular lens and multifocal intraocular lens in pseudophakic after phacoemulsification].
abstract: OBJECTIVE
  To compare the clinical efficacy of accommodative intraocular lens and multifocal intraocular lens in pseudophakic after phacoemulsification.
  
  
  METHODS
  A total of 54 eyes from 32 patients undergoing phacoemulsification received intraocular lens based on the principle of voluntary. Twenty-four eyes from 13 patients [16 eyes from 8 male participants and 8 eyes from 5 female participants, mean age (60.5 +/- 6.3) years] who had implantation of 1CU accommodative intraocular lens were randomized into experimental group. Thirty eyes from 19 patients [18 eyes from 11 male participants and 12 eyes from 8 female participants, mean age (61 +/- 6) years] who had implantation of Array multifocal intraocular lens were randomized into control group. All participants were age related cataract patients. Main outcome measures include best corrected distance visual acuity, distance corrected near vision, near point, the accommodation amplitude and stereopsis. All the clinical data were obtained at 3 months postoperatively and analyzed of covariance after controlling the factor of age.
  
  
  RESULTS
  (1) At 3 months postoperatively, all 1CU lens maintained good centricity. No patients with 1CU had undergone fibrosis, conglutination and remarkable posterior capsule opacification (PCO). Patients who received Array multifocal intraocular lens had not undergone other complications. (2) At 3 months postoperatively, best-corrected distance visual acuity were similar between the 1CU group and Array group (4.96 +/- 0.15 versus 5.02 +/- 0.08, P = 0.085). (3) Distance corrected near vision were similar between the two groups (4.65 +/- 0.15 versus 4.60 +/- 0.10, P = 0.398). (4) Subjective near point were similar between the two groups [(56 +/- 9) cm versus (61 +/- 11) cm, F = 0.065, P = 0.80]. (5) The accommodation amplitude were similar between the two groups [(1.30 +/- 0.40) D versus (1.20 +/- 0.36) D, P = 0.093]. (6) Patients with a accommodative intraocular lens achieved significantly better stereopsis than patients with multifocal Intraocular lens (43.24'' +/- 18.25'' versus 60.00'' +/- 23.09, P = 0.543).
  
  
  CONCLUSIONS
  Patients who received 1CU accommodative Intraocular lens demonstrated partial near vision when kept best distance vision. Our research found no significant difference between two groups in corrected distance vision acuity, distance corrected near vision, subjective near point, accommodation amplitude and near vision corrected stereopsis.
