Method for manufacturing an optical component, including a substrate made of a fusible material, includes the following steps a) and b) of steps a), b) and c), or steps a), b), c) and d): a) roughing; b) fine grinding; c) polishing; and d) finishing. The method includes steps, subsequent to any one of steps b), c) and/or d): e) inspecting the optical surface of the optical component; f) detecting and locating at least one surface defect to be eliminated; g) for each surface defect, applying a laser beam to an area emcompassing the defect, so as to produce a local remelting of the fusible material, and to form, at the location of the defect, an area of material remelted; h) polishing the optical surface including at least one area of remelted material, to produce a polished optical surface free of surface defects, and continuing with steps c) and d).
