Multimodal imaging in an idiopathic spontaneously absorbed cataractous lens: A rare case report

To report an unusual and rare case of idiopathic spontaneous absorption of the cataractous lens and its multimodal imaging features.

A 56-year-old female presented with a complaint of diminution of vision in both eyes (OU). Slit lamp examination of the right eye (OD) revealed Morgagnian cataract with a normal anterior segment. Slit lamp examination of the left eye (OS) revealed absorbed cataractous lens with intact lens capsule with clear visual axis. Fundus examination OS was unremarkable. No history of trauma, past ocular surgery or any ocular or systemic disease. Ultrasonography B-scan OU was unremarkable. Her blood examination was normal. Anterior segment optical coherence tomography showed increased anterior chamber depth OS. It also showed Morgagnian cataractous lens with nucleus in the bag OD and absorbed cataractous lens with thin adhered capsular bag OS. Scheimpflug imaging also showed decreased densitometry OS. She underwent successful phacoemulsification in OD with in-the-bag placement of intraocular lens. For OS with absorbed lens, she underwent phacoemulsification with anterior circular curvilinear capsulorhexis using a capsulotomy forceps. The cortical matter in the bag area was aspirated with implantation of intraocular lens in the ciliary sulcus over the intact capsule rim.

The patient underwent phacoemulsification with anterior continuous curvilinear capsulorhexis with intraocular lens placement in the ciliary sulcus OS.

This case is first of its kind in the literature. The role of ultrasound B-scan, anterior segment optical coherence tomography, and Scheimpflug imaging in the preoperative evaluation of capsulolenticular status and subsequent successful management is discussed.
