Abstract

The present invention relates to an ophthalmic apparatus and to a treatment site measuring method for the apparatus. The ophthalmic apparatus according to the present invention comprises: a first image unit for capturing the lower region of a retina so as to generate an image of the captured retina; a second image unit for capturing the local region of the retina indicated by a surgical operator so as to generate an image of the captured local region of the retina; and a control unit for mapping the image of the local region of the retina generated by the second image unit to the image of the retina generated by the first image unit based on the image of the retina generated by the first image unit.

First claim

What is claimed is:

1 . An ophthalmic apparatus for treating a retinal disease, comprising:
a first image unit generating a first image comprising a lower region of the retina; a second image unit generating a second image of the retina during a treatment process; and a control unit mapping the second image generated by the second image unit to the first image generated by the first image unit.

2 . An ophthalmic apparatus of claim 1 , wherein a captured area in the second image is smaller than a captured area in the first image.

3 . The ophthalmic apparatus of claim 1 , further comprising:
an image analysis unit analyzing the first image generated by the first image unit; and a memory unit storing the first image analyzed by the image analysis unit.

4 . The ophthalmic apparatus of claim 3 , wherein the image analysis unit analyzes a specific region of the first image and sends analyzed informations regarding the specific region to the memory unit.

5 . The ophthalmic apparatus of claim 4 , wherein the specific region of the first image comprises macula flava.

6 . The ophthalmic apparatus of claim 3 , further comprising a display unit displaying the first image and the second image generated by the first image unit and the second image unit.

7 . The ophthalmic apparatus of claim 6 , wherein:
grids are displayed in the first image displayed on the display unit, and the second image is mapped to a corresponding grid region of the first image.

8 . The ophthalmic apparatus of claim 6 , wherein the first image unit comprises a fundus oculi image unit which captures and generates the first image.

9 . The ophthalmic apparatus of claim 6 , wherein the second image unit comprises a view finder viewed by an operator.

10 . A method of operating an ophthalmic apparatus treating retinal disease, the method comprising steps of:
(a) providing a first image of a fundus oculi region of the retina; (b) generating a second image of the retina during a treatment process; and (c) mapping the second image and the first image based on the first image.

11 . The method of claim 10 , wherein a captured area in the second image is smaller than a captured area in the first image.

12 . The method of claim 10 , wherein:
the ophthalmic apparatus further comprises an image analysis unit which analyzes images of fundus oculi region of the retina, and the step (a) comprises analyzing and extracting information regarding a specific region in the first image by the image analysis.

13 . The method of claim 12 , wherein:
the ophthalmic apparatus further comprises a memory unit which stores analyzed information by the image analysis unit, and a step of storing the information regarding the specific region to the memory unit is further performed between the step (a) and the step (b).

14 . The method of claim 13 , wherein the information regarding the specific region comprises at least one of macula flava and blood vessel locations of the retina.

15 . The method of claim 12 , wherein the ophthalmic apparatus further comprises a display unit which displays the first image and the second image.

16 . The method of claim 15 , wherein the step (c) comprises a step of displaying grids in the first image displayed on the display unit and mapping the second image to a corresponding grid region location in the first image.

17 . The method of claim 15 , wherein the ophthalmic apparatus further comprises a fundus oculi image unit which generates the first image.

18 . The method of claim 15 , wherein the ophthalmic apparatus further comprises a view finder which generates the second image in the step (b).
