Introduction:

Uveitis-glaucoma-hyphema syndrome (UGH) is a rare complication of cataract surgery, due to mechanical chafing exerted by an intraocular lens (IOL) on the iris.

Clinical case:

A 64-year-old man with a history of cataract surgery, who presented decreased visual acuity and pain in the right eye. The ophthalmological examination revealed signs of anterior uveitis, elevated intraocular pressure (IOP), microhyphema, and a single-piece foldable IOL in the sulcus that caused a mechanical chafing with the posterior face of the iris. The medical treatment was insufficient; for this reason, a folding simple-piece IOL explant surgery was performed and replaced by a three-piece IOL. Postoperative evolution was favorable.

Conclusion:

Should be suspected this complication in patients with a history of cataract surgery, especially in cases in which the IOL is in single-piece and has been implanted outside the capsular bag.
