Scuba diving can be practiced recreationally or professionally. In both modalities the diver can be exposed to risks such as decompression syndrome and thus, the use of a hyperbaric chamber, hyper-oxygenation of the gas cylinder, barotrauma, and immersion in closed circuits. These situations have some phenomena in common, such as the great pressure differences, which can cause a wide range of alterations, including ophthalmological ones. The development of index myopia and nuclear cataract are ocular findings frequently associated with increased oxygen pressure. In this context, an imbalance is established between oxidative species and antioxidant defences, such as glutathione, which has a key role in maintaining the transparency of the lens. The cases are presented of 2 young coral fisher patients, who had recently developed a progressive myopisation associated with nuclear cataracts., (Copyright © 2020 Sociedad Española de Oftalmología.

Soft contact lenses are a good alternative to the use of glasses for the correction of refractive defects. However, improper use can be associated with complications.
