Clinical course of lens capsule fragment adherent to the posterior corneal surface after cataract surgery

Purpose: The purpose of the study was to evaluate the clinical features and outcomes of lens capsule fragment (LCF) adherent to the posterior corneal surface after cataract surgery. Methods A total of 12 eyes from 12 patients were included with a mean follow-up duration of 19.4 ± 12.6 months. Demographics and clinical features were collected by reviewing medical records and slitlamp photographs. Outcome parameters included corrected distance visual acuity (CDVA), central corneal thickness, and anterior segment optical coherence tomography (AS-OCT) features. Results All LCF located centrally and remained fixed and turned to semitransparent in a mean time of 28.7 ± 20.1 days. The AS-OCT revealed an extra membrane at the posterior corneal surface, with an underlying intact Descemet membrane in 9 eyes. All patients experienced corneal edema associated with LCF, which was medically managed and resolved in a mean time of 58.1 ± 40.2 days. CDVA improved from logarithm of minimum angle of resolution scores of 0.91 ± 0.63 preoperatively to 0.25 ± 0.18 at 2 months after surgery. None of the patients expressed subjective visual complaints. Conclusions LCF adherent to the posterior corneal surface caused prolonged corneal edema after cataract surgery, but exhibited no clinically significant complications in the midterm follow-up. AS-OCT provided useful diagnostics and differentiating features.
