title: Pupil ovalization after phakic intraocular lens implantation is associated with sectorial iris hypoperfusion.
abstract: OBJECTIVE
  To investigate iris perfusion in patients with and without pupil ovalization after phakic intraocular lens implantation.
  
  
  METHODS
  Comparative retrospective randomized case series of 6 participants, each with a regular pupil, and 6 participants with pupil ovalization after phakic intraocular lens implantation for high myopia were included in the study. Indocyanine green angiography was performed between 20 and 40 months (mean +/- SD, 26 +/- 6.1 months) after lens implantation.
  
  
  RESULTS
  Iris perfusion defects were found in 5 of 6 patients with pupil ovalization. No perfusion deficits were noted in patients with round pupils.
  
  
  CONCLUSIONS
  Iris ovalization after phakic intraocular lens implantation may be associated with a lack of iris perfusion and with secondary ischemia. Patients with these lenses and pupil ovalization should be followed regularly.
