title: A comparison of the rate of refractive growth in pediatric aphakic and pseudophakic eyes.
abstract: OBJECTIVE
  To compare the rate of refractive growth in pseudophakic children's eyes to that of aphakic eyes.
  
  
  METHODS
  Multicenter, retrospective observational case series.
  
  
  METHODS
  83 patients with pseudophakic eyes (100 eyes) and 74 patients with aphakic eyes (106 eyes), with an age of surgery between 3 months and 10 years and a minimum follow-up time of 3 years or more, depending on the age at surgery.
  
  
  METHODS
  A logarithmic model was used to analyze the rate of refractive growth for each eye.
  
  
  METHODS
  Age at surgery, intraocular lens power, intraocular lens A-constant, initial postoperative refraction, final refraction, and final age.
  
  
  RESULTS
  Overall, pseudophakic eyes showed a lesser rate of refractive growth than aphakic eyes (-4.6 diopter vs. -5.7 diopter, P = 0.03). This trend was also present but less significant when the eyes were grouped into those less than 6 months of age at surgery (-3.3 diopter vs. -4.6 diopter, P = 0.09) and older patients (-5.0 diopter vs. -6.1 diopter, P = 0.07). However, the mean quantity of myopic shift was greater in pseudophakic eyes than in aphakic eyes (-5.26 diopter vs. -4.54 diopter), despite shorter follow-up times in the pseudophakic eyes. This is due to the optical effects of a constant intraocular lens power in a growing eye.
  
  
  CONCLUSIONS
  Pediatric pseudophakic eyes have a slightly lesser rate of refractive growth than aphakic eyes. The new rate values should be used for predicting future refractions in these eyes.
