A new contact lens for posterior vitreous photodisruption.

Effective and safe photodisruption requires that the laser pulse be brought to a fine focus. Contact lenses are generally required to compensate for the optical aberrations of the eye which degrade the laser focus. The theoretical analysis of these aberrations has led to the construction of a contact lens which minimizes aberrations in the posterior vitreous. Clinical applications confirm the increased efficacy and safety of posterior vitreous photodisruption using this contact lens.
