Ignipuncture

Ignipuncture (Latin: Ignis (fire) + puncture) is the procedure of closing a retinal separation by transfixation of the break via cauterization. The procedure was pioneered and named by Jules Gonin in the early 1900s.[1] Due to the risk of severe complications and the advent of lasers for the controlled delivery of energy, ignipuncture became an obsolete procedure; since the 1980s, ignipuncture has been performed using safer techniques like endophotocoagulation.

Astigmatism

Astigmatism is a widespread vision condition that can cause people to have blurred vision. It's caused by an imperfection in the cornea or lens of the eyes. Corneal astigmatism is when the cornea isn't evenly curved and smooth. Lenticular astigmatism is when the shape of the lens is distorted. Both conditions can be corrected by using toric contact lenses.[2]
