Posterior capsular opacification is a common complication following extracapsular cataract surgery. Its time of onset after surgery, rate of development and affect on vision vary greatly from one individual to another.

In this case report, we describe the rapid development of posterior subcapsular opacification over a 12‐day period. This occurred four years after extracapsular cataract extraction and intraocular lens implantation via the technique of phakoemulsification.
