12 and 13 show a vision correcting jig showing still another embodiment of the present invention. This visual acuity correction device includes an R-shaped cap-shaped corneal suction member 40 and a corneal pressing member 41 inserted into the corneal suction member 40. The material of the corneal suction member 40 and the corneal pressure forming member 41 is arbitrary as long as it is harmless to the living body, and synthetic resin, glass, metal, nonmetal, or the like is used.
[0054]
The corneal suction member 40 has a shape in which a space portion 42 is formed between the corneal surface and the corneal surface when the corneal suction member 40 is put on the cornea 60. The purpose is to separate the cornea 60 from the crystalline lens 61 and to fix the corneal suction member 40 to the cornea 60 so that the corneal pressing member 41 can accurately press the target position of the cornea 60.
[0055]
The corneal suction member 40 is provided with an air suction port 43, a corneal pressing member insertion port 44, and an ophthalmic solution injection port 45.

[0059]
Next, a corneal correction method using the visual acuity correction device of FIGS. 12 and 13 will be described. However, the numerical values listed here are merely examples, and the present invention is not limited thereto. First, the eyelid is heated at about 40 ° C. to 42 ° C. for about 10 minutes to 15 minutes using the above-described eye mask or the like to sufficiently soften the cornea 60. During that time, the corneal suction member 40 of the vision correction device and the heating members 46 and 50 of the corneal pressing member 41 are heated to about 40 ° C. to 42 ° C. by turning on the respective temperature control devices. A cooling liquid is also filled in a cylinder or the like and cooled to about 4 to 9 ° C.
[0060]
At the time when the cornea 60 is sufficiently softened, the eye mask is removed and the cornea 60 is immediately covered with the corneal suction member 40 which has been sterilized by heating while holding the corneal pressing member insertion port 44. In this case, a gel-like disinfecting ophthalmic solution is applied to the contact surface of the corneal suction member 40 with the cornea 60 and the surface of the cornea 60.
[0061]
After covering the cornea 60 with the corneal suction member 40, the vacuum suction device is turned on and the air in the space 42 is sucked from the air suction port 43. As shown in FIG. And the corneal suction member 40 is fixed to the cornea 60. Thereby, even when the cornea 60 and the crystalline lens 61 are too close to each other, both are separated.
[0062]
This state is maintained for about 6 to 8 minutes, and if necessary, the cornea 60 is reheated by the heating member 46 of the corneal suction member 40 to maintain the flexibility of the cornea 60. During that time, if the surface of the cornea 60 dries, the flexibility of the cornea 60 decreases, so the sealing stopper 51 of the ophthalmic solution inlet 45 is removed, and about 0.5 cc to 1.0 cc of a normal disinfecting ophthalmic solution is dropped with a dropper or the like. Immediately after being injected into the surface of 60, it is sealed with a sealing stopper 51. In this case, it is necessary to inject an ophthalmic solution heated to about 40 ° C. to 42 ° C. It is necessary to inject this ophthalmic solution every 4 to 5 minutes and to keep the cornea 60 in a moist state at all times.
[0063]
After the instillation of the ophthalmic solution, the cornea pressing member 41 is advanced, and the cornea 60 is pressed by the eccentric crescent-shaped head portion 48, and the lower portion of the cornea is shaped according to the shape of the head portion 48 as shown in FIG. Correct to a bulging curved shape. At this time, it is preferable that the corneal pressing member 41 is gradually pushed into the corneal pressing member about 2 mm to 5 mm in several steps. For this reason, if a scale or the like is provided on the rod portion 49 of the corneal pressing member 41, the pushing amount of the head portion 48 is also accurate.
[0064]
After the cornea 60 is corrected into a predetermined shape by the corneal pressing member 41, the heat generating members 46 and 50 are turned off, and the cooling liquid is immediately supplied from the head part 48 through the cooling liquid injection passage 49 of the corneal pressing member 41 to about 5 to 10 cc. It is poured out toward the central part of the cornea 60. As described above, the cell tissue of the softened cornea 60 is thereby rapidly cooled, and the corrected corneal shape is fixed.
[0065]
Thereafter, the vacuum suction device is turned off, the sealing stopper 51 of the eye drop inlet 45 is opened, and outside air is introduced into the space 42 of the corneal suction member 40, so that the corneal suction member 40 is separated from the cornea 60. The corneal suction member 40 is removed by holding the corneal pressing member insertion opening 44.
[0066]
According to the above procedure, the cornea 60 is corrected according to the shape of the head portion 48 of the corneal pressing member 41, and the first correction treatment is completed. A visual acuity test of the patient is performed, and if the desired visual acuity has not been recovered, a second correction treatment is performed several days later. In the second treatment, by finely adjusting the position of the corneal suction member 40, it is possible to finely adjust the pressing position of the cornea 60 by the head portion 48 of the corneal pressing member 41. Note that the corrected shape of the cornea 60 shown in FIG. 13 is suitable for bifocal use.
