title: [Refraction shift after intraocular lens implantation in children].
abstract: OBJECTIVE
  To evaluate the refraction shift after posterior chamber intraocular lens (PC-IOL) implantation in children.
  
  
  METHODS
  A long term retrospective study involved 65 eyes of 65 patients aged from 5 to 12 years who underwent PC-IOL implantation between December 1988 and December 1994. The mean follow-up was 7.1 years (range 5 to 10 years). Refraction shift, keratometric readings and axial length were periodically measured. Sixty-five healthy eyes were in the control group.
  
  
  RESULTS
  The mean preoperative axial length of the surgical group was (22.48 +/- 0.44) mm, and of the control group, (22.43 +/- 0.41) mm. There was no statistically significant difference in axial length after 10 years in both groups, (23.45 +/- 0.53) mm in surgical group and (23.41 +/- 0.50) mm in control group. All the eyes showed a myopic drift with 3.29 D in surgical group and 1.75 D in control group (F = 2.318, P < 0.05).
  
  
  CONCLUSIONS
  The ocular growth of children is found to be unaffected by the PC-IOL implantation, the choice of IOL power should be retained in physiological hyperopia in pseudophakic children.
