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± 6.1months) 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. Conclusion: 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.
