To report 2 cases of corneal edema, haze, and thinning in patients after undergoing selective laser trabeculopasty.
Selective laser trabeculoplasty was performed for the treatment of primary open-angle glaucoma on 2 patients who subsequently developed corneal stromal haze within 24 to 48 hours of the procedure.
The patients were treated with topical steroids for several weeks. Although their corneal edema resolved, both patients were left with residual corneal scarring and thinning. One patient had a significant hyperopic shift.
Corneal edema, haze, and thinning after selective laser trabeculoplasty is an extremely rare event, with only 2 other cases reported in the literature. Although certain causes are postulated to play a role in this complication, it is not yet understood what may predispose a patient to corneal changes as a result of this laser procedure.
报告 2 例选择性激光小梁成形术后患者发生的角膜水肿、混浊和变薄。
对 2 例原发性开角型青光眼患者行选择性激光小梁成形术治疗，术后 24 至 48 小时内出现角膜基质混浊。
患者接受了数周的局部皮质类固醇治疗。尽管他们的角膜水肿消退，但两名患者都留下了残余的角膜瘢痕和变薄。一名患者出现明显的远视漂移。
选择性激光小梁成形术后发生的角膜水肿、混浊和变薄是一种极其罕见的事件，文献中仅报告了另外 2 例。尽管某些原因被推测在这种并发症中起作用，但尚不清楚是什么原因导致患者因这种激光手术而发生角膜变化。
