Problems solved by technology

[0012] In view of the above, it can be inferred that the ophthalmological community has not been aware of the possibility that abnormalities in the corneal surface morphology can cause dry eye syndrome, or even if it is aware, it is not aware of the method of treating dry eye syndrome by improving the abnormality of the corneal surface morphology
Therefore, no one has attempted to treat dry eye by correcting the shape of the cornea

Embodiment 1

[0088] Image 6 It is a four-phase map of the cornea taken by Anterior Segment Tomography. available through the Image 6 Corneal surface height map on the upper left side (map labeled Anterior Float) to confirm the surface height deviation of the cornea.

[0089] Figure 7 For cutting from 0 degrees to 180 degrees Image 6 The cross-sectional view of the four-phase diagram. through the Figure 7 The cross-sectional view of the corneal surface height map on the upper left side can easily confirm the corneal BFS and the corresponding corneal surface height deviation.

[0090] like Image 6 As shown in the corneal surface height map on the upper left side, the arithmetic unit extracts and confirms the surface height deviation position using the corneal surface height map obtained from the cornea measurement unit, and the result is a slightly deviated part in the direction of 225 degrees from the center of the cornea, as shown in the figure. Based on BFS, there is a part w...

Embodiment 2

[0094] Figure 9 Four-phase map of the cornea taken and analyzed by Anterior Segment Tomography. available through the Figure 9 Corneal surface height map on the upper left side (map labeled Anterior Float) to confirm the surface height deviation of the cornea.

[0095] Figure 10 For cutting from 0 degrees to 180 degrees Figure 9 A cross-sectional view of the corneal tetraphasic diagram. through the Figure 10 The cross-sectional view of the corneal surface height map on the upper left side can easily confirm the corneal BFS and the corresponding corneal surface height deviation.

[0096] like Figure 9 As shown in the corneal surface height map on the upper left side, the arithmetic unit uses the corneal surface height map obtained from the cornea measurement unit to extract and confirm the surface height deviation position. In addition, the right side is outside the 2 mm area, and there is a portion (dark yellow) with a surface height of 30 μm based on BFS.

Abstract

The laser cornea cutting system according to the present invention comprises: a laser measurement unit for measuring a cornea to obtain cornea state data; a laser control means for controlling the output intensity, range, amount, and time of the laser according to the cutting position and cutting form of the cornea, in accordance with a cornea cutting scheme generated on the basis of the cornea state data; the laser module is used for irradiating laser to the cornea according to the control signal applied by the laser control unit, the state data of the cornea comprises a cornea surface height map, and cornea cutting is carried out on the surface height deviation part of the cornea to treat xerophthalmia.
