Background

Cataract is the leading cause of visual impairment and, consequently, cataract surgery is the most common surgical procedure performed worldwide to restore visual acuity and good quality of life [1]. With modern techniques of small incisions and foldable intraocular lenses (IOLs), cataract surgery has become a “minimally invasive” procedure with fast recovery and minimal complication rate. Most IOLs are designed to be implanted in the capsular bag after uneventful phacoemulsification. In case of complications during surgery, such as anterior capsular tears (with or without posterior extension), posterior capsular rupture, or zonular dehiscence, some of these IOLs can be placed in the sulcus. This technique is performed by most surgeons and has been widely described [2]. Although visual outcome may be similar when correctly executed, sulcus IOL implantation can induce some particular postoperative complications that require specific therapy. Pigment dispersion is the most common finding and has been described by several authors [3], [4]. Indeed, IOLs in the sulcus can mechanically rub against the posterior surface of the iris and provoke pigment dispersion. These pigments can later give rise to ocular hypertension by accumulating in the trabecular meshwork. One-piece IOL with square edge haptics may increase this risk as they tend to have thicker haptics. We report an interesting case where pigment dispersion, ocular hypertension, and iris atrophy were mistakenly treated as a non-granulomatous anterior uveitis.
