Adjunct oxygen therapy helps improve corneal edema after cataract surgery

Transcorneal oxygen therapy as an adjunct to conventional therapy for severe corneal edema following cataract surgery preserved more endothelial cells and decreased corneal edema faster than conventional therapy alone or conventional therapy plus systemic oxygen, according to a study.Forty-five patients with central corneal thickness of more than 1,000 µm at day 1 postoperatively were divided into three equal groups: a control group receiving conventional medical therapy, a group receiving medical therapy plus systemic normobaric 100% oxygen by facemask and a group receiving medical therapy and transcorneal 100% oxygen. Oxygen therapy continued for 3 weeks, and no oxygen-related complications were observed.
