A 52-year-old male presented with blurred vision in both eyes. Examination revealed bilateral persistent pupillary membrane [Figure 1]a, Krukenberg's spindle [Figure 1]b, and immature cataract with normal intraocular pressure (IOP). Radial pigmented zonular fibers were noted over the anterior lens capsule [Figure 1]c, extending beyond the usual termination zone with a central zonule-free area. Open angles with pigmented trabecular meshwork were noted [Figure 1]d. Fundus was unremarkable, except for peripheral retinal drusen. Long anterior zonule (LAZ) has two phenotypes: type 1 is seen in young patients with late-onset retinal degeneration (LORD) and type 2 is seen in older hypermetropic patients. This rare entity serves as a surrogate marker for underlying sight-threatening diseases like glaucoma and retinal degeneration and cautions the surgeon for a meticulous capsulorhexis.
