title: Secondary intraocular lens (IOL) implantation: anterior chamber versus scleral fixation long-term comparative evaluation.
abstract: OBJECTIVE
  To compare the long-term efficacy of a secondarily implanted flexible angle supported anterior chamber (AC) intraocular lens (IOL) with sclerally fixated IOL as a secondary procedure in patients with aphakia.
  
  
  METHODS
  Sixty patients with aphakia were recruited for this study. The patients were randomly divided into two groups: Group I patients underwent secondary implantation with AC IOL (Kelman Z type multiflex Domi classic AC IOL) and Group II patients underwent secondary implantation with scleral fixated IOL (Hanita lens with two eyelets). Postoperatively, the patients were followed up at 1 week, monthly for 6 months, and at twice yearly intervals for 5 years (mean follow-up was 3 years).
  
  
  RESULTS
  Best-corrected visual acuity of 6/18 or better was achieved in 36.6% (11/30) of patients in Group I and 30% (9/30) of patients in Group II after a mean follow-up of 3 years. The complication rate was higher in Group II as compared to Group I. The authors encountered a total of 23 complications in the sclerally fixated group and 11 in the AC IOL group (p=0.004). Uveitis and ciliary tenderness were the most common complications in Groups I and II, respectively.
  
  
  CONCLUSIONS
  For secondary implantation of IOL in aphakic patients, Kelman Z type multiflex Domi classic AC IOL is a better rehabilitation modality as compared to the scleral fixated Hanita IOL.
