An arrangement for laser treatment of vitreous floaters. The arrangement for laser vitreolysis of an eye includes an OCDR system, a laser system having a deflection unit, optical elements that couple the OCDR system and the laser system, a display unit and a central control and operating unit. The OCDR system is configured to localize the position of a floater along the optical axis of the OCDR system. The laser system is configured to destroy the floaters by application of laser pulses, and the central control and operating unit is configured to focus the laser system onto the position of the floater and to activate it, in particular when the position of the laser focus and the floater match in a sufficient manner. The present invention relates to an arrangement for the gentle, low risk and painless laser treatment of vitreous floaters, which allows a partially or fully automated therapy.

A system for performing a microsurgery or ocular surgery including a cannula having an intraocular portion connected to an infusion tube. The intraocular portion includes fenestrations at its distal end. The intraocular portion receives fluid through the infusion tube and dispenses the fluid through the fenestrations lessening the flow at an infusion site in an eye. The surgical apparatus includes a vitreous cutter. The vitreous cutter includes a suction tube at one end and a shaft at another end. The cutting port cuts vitreous into smaller pieces or a laser that liquefies the vitreous. The shaft receives the cut vitreous pieces and the suction tube draws out the cut vitreous pieces from the eye. The surgical apparatus includes a vitreoretinal surgical tool having a vitreoretinal cutter. The vitreoretinal cutter has a scissor-like or forceps-like mechanism. The vitreoretinal cutter holds and/or cuts a membrane in the eye during the ocular surgery.

In certain embodiments, an ophthalmic laser surgical system for treating a floater in a vitreous of an eye includes a floater detection system, a laser device, and a computer. The floater detection system determines the location of the floater in the vitreous of the eye. The laser device directs a laser beam along a laser beam path towards the floater. The computer accesses a three-dimensional scan pattern for the laser beam that yields a three-dimensional pulse pattern of laser pulses. The three-dimensional pulse pattern has a bubble shield pulse pattern at the posterior side of the three-dimensional pulse pattern. The bubble shield pulse pattern forms a bubble shield that reduces laser radiation exposure at a retina of the eye. The computer instructs the laser device to direct the laser beam towards the floater according to the three-dimensional scan pattern.
