To evaluate the clinical features and outcomes of lens capsule fragment (LCF) adherent to the corneal endothelium after cataract surgery.
This retrospective case series consisted of 12 eyes from 12 patients. Demographics and clinical features were gathered by reviewing medical records and external eye photographs. Preoperative corrected distance visual acuity (CDVA) and central corneal thickness were collected. Outcome parameters included CDVA, central corneal thickness, endothelial cell density (ECD), and anterior segment optical coherence tomography (AS-OCT) features in the early and late postoperative period, which was defined by the mean resolution time of corneal edema.
The mean follow-up duration was 581.3 ± 377.1 days (mean ± SD). Prolonged postoperative corneal edema was successfully managed medically in all eyes, with a mean clinical resolution time of 58.1 ± 40.2 days. The location of the adherent LCF remained fixed, but turned from transparent to semi-transparent in a mean time of 28.7 ± 20.1 days. Nine of the 12 eyes (75%) had pigment coatings on the LCF. In 9 eyes, the AS-OCT clearly revealed an extra membrane at the posterior corneal surface, with underlying intact Descemets membrane. The postoperative mean ECD showed a 31% decrease in the study eye comparing to the fellow eye, although not significant (P = .138, n = 5). The CDVA improved from logarithm of minimum angle of resolution 0.91 ± 0.63 (pre-op) to 0.25 ± 0.18 (2 months). None of the patients reported subjective visual symptoms.
No clinically significant complications encouraged surgical intervention. AS-OCT provided good diagnostic and differentiating features.

The white arrows indicate the orientation of the anterior segment OCT. The anterior segment OCT reveals an extra membrane (C, G), or a focal thickening of the inner corneal layer (K). In the late postoperative period, various amount of scarring is present (D, H, L).
