CPT® Code 66830

Removal of secondary membranous cataract (opacified posterior lens capsule and/or anterior hyaloid) with corneo-scleral section, with or without iridectomy (iridocapsulotomy, iridocapsulectomy)

Secondary membranous cataracts, also known as posterior capsule opacification, are a common complication that can occur following cataract surgery. This condition arises when epithelial and fibroblastic cells, which may remain after the removal of the cataract, proliferate on the anterior surface of the posterior lens capsule. As these cells multiply, they create a hazy membrane that can obstruct vision. The procedure coded as CPT® 66830 involves the surgical removal of this secondary membrane, which may include the opacified posterior lens capsule and/or the anterior hyaloid. The operation is performed through a corneo-scleral section, which is an incision made in the cornea and sclera of the eye. In some cases, the procedure may also involve an iridectomy, iridocapsulotomy, or iridocapsulectomy, which are techniques used to access the posterior capsule by incising the iris and the capsular membrane surrounding the intraocular lens. This surgical intervention aims to restore clear vision by eliminating the obstructive membrane and ensuring proper intraocular pressure is maintained during and after the procedure.
