摘要： Disclosed is a method capable of reliably measuring the thickness of the retinal nerve fiber layer in an OCT retinal cross-sectional image with a large change in curvature. The method of measuring a retinal layer includes: step S10 of obtaining an OCT layer image of a retina; step S12 of detecting a reference boundary line indicating a retinal layer in the obtained OCT image; step S14 of obtaining an aligned OCT image by aligning a vertical position of each column of the OCT image so that the detected reference boundary line becomes a baseline; step S20 of predicting retinal layer regions from the aligned OCT image; step S22 of calculating boundary lines between the predicted retinal layer regions; and step S30 of restoring the calculated boundary lines to positions of the boundary lines of the retinal layer of the original OCT image by aligning the vertical positions of the calculated boundary lines of the retinal layer for each column so that the baseline becomes the reference boundary line again.

摘要： An apparatus and a method for processing a lens, which can cut off and remove an unnecessary part of the rim of a round(blank) lens by using a milling cutter operated spirally, are disclosed. The method for processing a lens comprises the steps of: getting a milling cutter in contact with the surface of the lens; and moving the milling cutter along a single spiral processing path spirally surrounding an eyeglass lens part of the central part of the lens so that the milling cutter rotates around the eyeglass lens part several times, to form grooves of predetermined depths in the lens, whereby the lens is cut and an unnecessary part of the rim of the lens is separated and removed along a shape of the eyeglass lens part. Wherein a width of each groove formed in each of rotation steps which form a single spiral processing path is partially overlapped with a width of groove formed in the former rotation step, and a depth of each groove formed in each rotation step is increased in every rotation step and finally, the lens is cut along the shape of the eyeglass lens part.
