Soemmering ring explained

Field:	Ophthalmology

Soemmering ring is an annular swelling of the periphery of the lens capsule.^[1] In 1828, Detmar Wilhelm Sömmerring observed posterior capsule opacification and then described Soemmering's ring^{[2] [3] [4]} as deposits of retained equatorial lens epithelial cells which continue to proliferate and form new cortical fibers which eventually form a ring of cortical fibers between the posterior capsule and the edges of the anterior capsule remnant.^[5]
