A 70-year-old male patient presented with gradual, progressive diminution of vision involving both the eyes. On examination, his best corrected visual acuity was 6/60 in both eyes. His cornea revealed a clear outer arcus which clearly defined outer and inner edges, and lucid interval. The inner arcus showed similarly clearly defined outer edge only with a clear outer lucid interval [Fig. 1a and b]. The patient had both eyes immature senile cataract for which he underwent sequential bilateral cataract surgery, the further detailed systemic evaluation did not reveal any significant no co-morbidities. Double arcus is a unique clinical entity which has been noted rarely in the literature.[1,2]
