A high-intensity pulsed-electrical-field (HIPEF) apparatus chemically induces lysis of ocular tissue within a localized portion of an eye. Instead of broadly applying a lysis affecting solution (e.g., plasmin) to the eye, the apparatus delivers solution to only a portion of the eye. The apparatus then alters the effectiveness of at least some of the solution delivered by applying a HIPEF to that solution. In some embodiments, for example, the apparatus delivers a solution that does not substantially affect lysis of ocular tissue and then enhances the solution's effectiveness by applying a HIPEF. As the apparatus applies the HIPEF with high precision, the HIPEF only enhances the effectiveness of the solution within select and localized portions of the eye. The apparatus is especially advantageous for vitreoretinal surgery, whereby the apparatus may selectively induce lysis of vitreous tissue within a localized portion of the vitreous cavity, without significantly affecting adjacent retinal tissue.
