Differential optical density of fluid in capsular bag distension syndrome

Capsular bag distension syndrome (CBDS) is a rare complication of cataract surgery due to collection of fluid behind the intraocular lens (IOL). Nd:Yag laser capsulotomy is commonly performed to release the fluid collection; however, the potential risk of infection and inflammation has led to adaptation of numerous surgical procedures. Clinical examination in an established case of CBDS reveals opalescent fluid behind the IOL with ballooning of the posterior capsule, which has different reflectivity on optical coherence tomography. However, the exact optical properties of this fluid are still unknown. A case of delayed CBDS with induced myopia due to change in IOL position because of fluid collection behind the IOL is presented.
