title: Long-term contact lens wear of children and teens.
abstract: OBJECTIVE
  To compare current symptoms, compliance, ocular health, and previous adverse events between current successful long-term contact lens wearers fit as children or as teenagers.
  
  
  METHODS
  People who had successfully worn soft contact lenses for at least 10 years completed an online survey about demographics, current wearing status, compliance, symptoms, and previous adverse events. A subset reported for a slit-lamp examination, autorefraction, autokeratometry, and specular microscopy. Statistical comparisons were made between those fit as children (12 years or younger) and those fit as teenagers (13 years or older).
  
  
  RESULTS
  Of the 175 subjects completing the online survey, 86 (49.2%) were fit as children and 89 (50.8%) fit as teenagers. Those fit as children wore their contact lenses for an average of 14.8 ± 3.4 hours per day, compared with 14.7 ± 3.6 hours per day for those fit as teenagers (P=0.74). Eighteen (20.9%) fit as children and 17 (19.1%) fit as teenagers reported ever having had a painful, red eye that required a doctor visit (P=0.76). Overall, there were no differences in ocular health between the groups. Those fit as children were more myopic than those fit as teenagers (-4.30 ± 1.69 and -2.87 ± 2.75, respectively; P=0.02).
  
  
  CONCLUSIONS
  Successful contact lens wearers fit as children are no more likely to report previous contact lens-related adverse events, problems with compliance, decreased wearing time, or worse ocular health than those fit as teenagers, so practitioners should not use age as a primary determinant in fitting children in contact lenses.
