“…The epithelium proliferates, lines the posterior capsule, and grows around the margin of the anterior capsule. The Sömmering ring is a ring formed in the periphery of the lens capsule [ 5 ].

“…Published reports of dislocated Sömmering rings are rare. Multiple factors predis-posed this patient to Sömmering ring formation, including cataract surgery at an early age and postoperative aphakia [ 5 , 8 , 9 ]. Wilson et al noted that Sömmering ring formation frequently occurs when lensectomy is performed early in childhood [ 7 ].…”

“…The Sömmering ring is held in position in the retro-iridal space by the ciliary zonule and can only be seen in cases of dislocation [ 5 ]. Guha observed that myopia is a predisposing factor for ring dislocation after reviewing 11 cases of dislocated Sömmering rings.…”

Patient: Male, 20-year-old Final Diagnosis: Aphakia Symptoms: Pain • redness • vision deterioration Clinical Procedure: — Specialty: Ophthalmology Objective: Rare disease Background: A Sömmering ring is a post-cataract opacity (PCO) formed due to the adhesion of anterior capsule edges to the posterior capsule. It is mostly associated with aphakic cases but has also been reported in pseudophakic eyes. It becomes clinically important when dislocation occurs. The purpose of this manuscript was to report a case of anterior dislocation of the Sömmering ring 14 years after lensectomy for congenital cataract. Case Report: We describe a 20-year-old man who presented to the emergency room with pain, photophobia, redness, and blurry vision in the right eye. The patient was known to have bilateral amblyopia and had undergone bilateral lens aspiration and anterior vitrectomy without intraocular lens (IOL) implantation 14 years prior to presentation. On examination, the intraocular pressure was normal, the conjunctiva had moderate diffuse injection, and the cornea had 2+ diffuse edema with bullae and Descemet folds. The anterior chamber was deep with semilunar-shaped solid white material consistent with the Sömmering ring in the anterior chamber. On dilated fundus examination, the view was hazy, and B-scan ultrasonography indicated highly reflective material in the vitreous cavity and a flat retina. Conclusions: Sömmering ring in the anterior chamber can be inflammatory and especially damaging to the corneal endothelium. If this complication occurs, timely intervention in the form of surgical removal is crucial to prevent endothelial cell loss and corneal decompensation. A thorough cleaning of the cortical matter after lens removal during primary surgery can reduce the risk of secondary formation of PCO. Implantation of IOL in myopic eyes can be considered to reduce the risk of Sömmering ring formation in the future and its complications.

“…Literature reports that Soemmering's ring and spontaneous lens absorption are two distinct diseases [ 1 , 2 ] that are uncommon and unlikely to occur concurrently in a single patient. Soemmering's ring was first discovered in 1928 by Soemmering as the deposit of residual equatorial lens' epithelial cells.…”

Soemmering's ring and spontaneous lens absorption are two distinct conditions that are uncommon and unlikely to occur simultaneously. We report a case of a 67-year-old man who presented with blurred vision in his left eye and has had poor eyesight since birth. His right and left eye visual acuities were 6/7.5 and hand movement (HM), respectively. There was no relative afferent pupillary defect (RAPD). The right eye’s examination was unremarkable. The left eye revealed a spontaneous rupture of the anterior lens capsule with partially absorbed lens material and the presence of Soemmering's ring. There was no evidence of phacodonesis. The left fundus appeared slightly hazy, while the retina appeared flat. Extraction of the left eye lens was performed for the patient, and he was left aphakic. In this case, the patient's Soemmering's ring was linked to the ruptured anterior lens capsule followed by spontaneous partial absorption of lens material, which caused deposition of residual lens filaments near the equator of the capsule sac. In addition to ocular trauma, patients with congenital rubella infection of the eye, uveitis, and Morgagnian cataract have reported spontaneous absorption of lens material. The exact mechanism by which cataracts dissolve spontaneously is unlikely to be the same in all patients. This patient who has had an unsightly left eye since birth is presumed to have been born with an ocular infection complicated by amblyopia. The presence of both the Soemmering's ring and spontaneous lens absorption is unusual in this case. Early attention to the precious fellow eye is critical to ensure that the other unaffected eye maintains an adequate vision and allows independent patient mobility.
