Abstract 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 (ASOCT) 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 followup. AS-OCT provided useful diagnostics and differentiating features. Keywords Lens capsule Phacoemulsification Corneal edema Anterior segment optical coherence tomography Descemet membrane detachment
Introduction The lens capsule is a transparent basement membrane composed of type IV collagen, with lens epithelial cells as interior linings. During phacoemulsification cataract surgery, continuous curvilinear capsulorhexis (CCC) is performed by removing a circular portion of the anterior lens capsule. However, if the circular

capsule breaks into small pieces and the cortex is already disturbed during CCC leading to a disorderly background, these small lens capsule fragments (LCF) may be unnoticed and unintentionally left inside the anterior chamber to adhere to the posterior corneal surface.
