A method of forming a laser ablation perimeter surrounding a defect in an optical device, the method characterized by comprising: a. starting application of a laser with a laser focus at a first position (800, 900, 1300), the first position within an area that will be surrounded by the laser ablation perimeter; b. translating the laser focus from the first position (800, 900, 1300) to a second position (805, 905, 1305), the second position (805, 905, 1305), being a part of the laser ablation perimeter; c. translating the laser focus about the defect along the laser ablation perimeter until the laser focus is proximate the second position (805, 905, 1305); d. closing the laser ablation perimeter by overlapping the laser focus at the second position; and e. returning the laser focus to the area surrounded by the laser ablation perimeter where laser ablation is then ceased; or a. starting application of a laser with a laser focus at a first position (1300, 1400), within an area that will be surrounded by the laser ablation perimeter; and b. translating the laser focus from the first position (1300, 1400) and about the defect until the laser focus crosses its own path, but not at the first position. a. starting application of a laser with a laser focus at a first position (800, 900, 1300), the first position within an area that will be surrounded by the laser ablation perimeter; b. translating the laser focus from the first position (800, 900, 1300) to a second position (805, 905, 1305), the second position (805, 905, 1305), being a part of the laser ablation perimeter; c. translating the laser focus about the defect along the laser ablation perimeter until the laser focus is proximate the second position (805, 905, 1305); d. closing the laser ablation perimeter by overlapping the laser focus at the second position; and e. returning the laser focus to the area surrounded by the laser ablation perimeter where laser ablation is then ceased; or a. starting application of a laser with a laser focus at a first position (800, 900, 1300), the first position within an area that will be surrounded by the laser ablation perimeter; b. translating the laser focus from the first position (800, 900, 1300) to a second position (805, 905, 1305), the second position (805, 905, 1305), being a part of the laser ablation perimeter; c. translating the laser focus about the defect along the laser ablation perimeter until the laser focus is proximate the second position (805, 905, 1305); d. closing the laser ablation perimeter by overlapping the laser focus at the second position; and e. returning the laser focus to the area surrounded by the laser ablation perimeter where laser ablation is then ceased; or a. starting application of a laser with a laser focus at a first position (1300, 1400), within an area that will be surrounded by the laser ablation perimeter; and b. translating the laser focus from the first position (1300, 1400) and about the defect until the laser focus crosses its own path, but not at the first position. a. starting application of a laser with a laser focus at a first position (1300, 1400), within an area that will be surrounded by the laser ablation perimeter; and b. translating the laser focus from the first position (1300, 1400) and about the defect until the laser focus crosses its own path, but not at the first position.
