title: Vision, subjective accommodation and lens mobility after TetraFlex accommodative intraocular lens implantation.
abstract: BACKGROUND
  The TetraFlex accommodating intraocular lens (IOL) was designed to supply the patients both satisfied far and near vision after cataract surgery. So we need to evaluate the safety, distance and near visual acuity, subjective accommodation and IOL mobility with the TetraFlex accommodating IOL implantation.
  
  
  METHODS
  Fifty eyes of 42 study-eligible cataract patients, who gave informed consent at a single eye clinic in China over a 10-month period, underwent phacoemulsification with TetraFlex IOL implantation. At three months postoperation, uncorrected visual acuities (UCVA), best corrected visual acuities (BCVA), distance-corrected near visual acuities (DCNVA), subjective accommodation using the defocus method, and pilocarpine-induced IOL mobility were measured.
  
  
  RESULTS
  No postoperative complications were noted in the study. Three months postoperation UCVA and BCVA were 20/40 or bettter in 82% (41/50) and 92% (46/50) of eyes, respectively; 66% (33/50) of the eyes had DCNVA of Jager (J) 4 or better at 3 months. In addition, the mean subjective accommodation was (0.94+/-0.61) diopters (D) (range from 0.50 to 1.50 D) and pilocarpine-induced IOL mobility was (337+/-124) microm (range from 121 to 501 microm) with the TetraFlex. High relationship (r2=0.901, P<0.01) was found between these two measurements.
  
  
  CONCLUSIONS
  Implantation of the TetraFlex is safe and leads to excellent uncorrected distance vision and good uncorrected near vision.
