A typical ocular coloboma results from the failure of the embryonic fissure of the optic cup to fuse along the line extending from the optic disc to the inferonasal border of the pupillary margin. The colobomatous defects usually occur in association with several other ocular or systemic pathologies. An isolated lens coloboma is a rare entity. It occurs because embryonic fissure fails to fuse during the fifth to seventh weeks of fetal life.Absence or weakening of zonular fibers in the area of the coloboma induces flattening, concavity, notching, and segmental contraction in that area. This results in high lenticular astigmatism.Outcomes of cataract surgery in cases of typical lens coloboma have been reported.We report the aberrometric changes following surgical management by lens extraction with intraocular lens (IOL) and capsular tension ring (CTR) implantation for visual rehabilitation in typical isolated lens coloboma.
