Pupil ovalization after phakic intraocular lens implantation is associated with sectorial iris hypoperfusion.
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.
