US12599502B2 - Ophthalmic Laser Surgical System with Bubble Shield for Reducing Retinal Radiation Exposure
Summary
USPTO granted patent US12599502B2 to Alcon Inc. (inventor: Zsolt Bor) for an ophthalmic laser surgical system that reduces retinal radiation exposure during floater treatment. The system uses a three-dimensional pulse pattern with a bubble shield pulse at the posterior side to form a protective bubble shield over the retina. The patent (CPC: A61F 9/008) contains 9 claims and was filed October 25, 2022.
What changed
USPTO issued patent grant US12599502B2 to Alcon Inc. for an ophthalmic laser surgical system designed to reduce retinal radiation exposure during laser surgery to treat floaters in the vitreous of the eye. The system includes a floater detection system, a laser device, and a computer that accesses a three-dimensional scan pattern producing laser pulses with a bubble shield pulse pattern at the posterior side. This bubble shield forms a protective barrier that reduces laser radiation reaching the retina.
For medical device manufacturers and IP professionals, this patent grant establishes exclusive IP rights for Alcon in ophthalmic laser technology with bubble shield protection. Competitors developing similar retinal protection mechanisms in laser eye surgery systems should assess freedom-to-operate implications and potential licensing needs. The patent does not impose compliance obligations but represents enforceable intellectual property rights with 9 claims covering the disclosed invention.

Abstract
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.
