Lens Changes With Hyperbaric Oxygen Therapy
The lens may also undergo changes after hyperbaric oxygen (HBO) therapy. A myopic shift seems to occur universally during the course of treatment with HBO. This change, thought to be due to a refractive change in the crystalline lens, usually reverses after cessation of HBO treatment. However, several reports have documented the development of nuclear cataract over the course of multiple HBO treatment sessions.
