# Interaction of an Iris Implantation Cyst with Pseudophakic Bullous Keratopathy: A Case Report

## TL;DR

This case report describes a rare interaction between an iris cyst and corneal swelling after cataract surgery.

## Contribution

The paper presents a unique case where two uncommon postoperative complications interacted unexpectedly.

## Key findings

- A patient developed an iris cyst and corneal edema after cataract surgery.
- The interaction between these complications was rare and previously unreported.
- The case highlights the complexity of postoperative outcomes in cataract surgery.

## Abstract

Background and Clinical Significance: Currently, the only effective treatment for cataracts is surgery. The most commonly employed method is phacoemulsification, a well-established procedure that uses ultrasound energy to fragment the lens, allowing for easier removal. Potential postoperative complications range from mild to severe corneal edema (pseudophakic bullous keratopathy), which may be caused by intraoperative endothelial cell damage, to the rare formation of iris cysts. Case Presentation: In this paper, we report the case of a patient who underwent cataract surgery in both eyes, where iris incarceration occurred during the surgical procedure, resulting in corneal edema and an iris cyst, both in the left eye. Secondary iris cysts are uncommon following phacoemulsification, with only a few cases reported in the recent literature. The cyst’s impact on corneal edema was unexpected, making this case particularly noteworthy and emphasizing the complexity of cataract surgery and its postoperative complications. Conclusions: This case illustrates the unique interaction between two infrequent complications of cataract surgery.
