Answer: Whether or not the Lens Implant after Cataract Surgery is gas permeable should be immaterial to going scuba diving. Unlike a contact lens that is placed on the surface of the cornea and requires oxygen, nitrogen and carbon dioxide permeability in order to sustain corneal transparency and integrity-an intraocular lens implant or IOL is within the eye and does not in any way impact corneal physiology. When scuba diving and wearing contact lenses this is an important feature-but not for lens implants. Thus, it is doubtful that the manufacturer or anyone would take the time to conduct oxygen permeability studies of the acrylic lens material used for this type of Lens Implant.
