Abstract

Subluxation of lens signifies partial displacement of crystalline lens or cataractous lens from its central position in the pupillary area. The surgical management of subluxated cataract or crystalline lens is a real challenge for the ophthalmic surgeon. With the availability of better surgical techniques and advanced instrumentation, now the surgeon is able to perform relatively a safe surgical procedure even in the presence of severe zonular dehiscence and restore useful vision. Suspensory ligament or zonule of Zinn is composed of cysteine rich glycoproteins. Fibrillin is the main component. Deficiency of cysteine or a defective fibrillin gene can cause zonular weakness in congenital diseases. Zonular damage and dehiscence occur in the acquired subluxations.
