Watch cataract surgery condensed into one and a half minutes

April 2018

During a recent trip to Bangladesh, we filmed a time-lapse video of a Sightsavers cataract operation taking place at Khulna BNSB hospital.

A standard operation takes 10 to 20 minutes – our film condenses this down into one and a half minutes to provide a glimpse of what’s involved.

Notice that two patients are present in the operating theatre at the same time: one is prepared for surgery by nurses while the other is being operated on. This enables the surgeon to start a new operation as soon as the first is finished, maximising the number of patients that can be treated each day. During the surgery, patients are given a local anaesthetic so they are conscious throughout.

More about cataracts

Cataracts are caused by a build-up of protein that clouds the eye’s lens, which can lead to blurred vision and, eventually, blindness.
