Posterior dislocation of an IOL-Ultrasound

Posterior dislocation of an IOL may occur during or shortly after cataract surgery. In these cases, posterior capsular rupture or zonular dialysis usually is present. The IOL rarely dislocates completely onto the retinal surface. It usually lies meshed into the anterior vitreous with one haptic still adherent to the capsule or iris. It may cause a vitreous hemorrhage by mechanical contact with ciliary body vessels. The IOL may be related to retinal detachment or cystoid macular edema secondary to vitreous changes. No age, gender or sex predilection is seen.

This is a case of middle aged male who had a previous history of cataract surgery and now presented with sudden loss of vision. In our patient,lens is very well visualized in pre-retinal space and is relatively fixed. There are thick membranes with internal echoes in vitreous s/o vitreous haemorrhage.
