Definitions
- the present invention relates to a medical device for keratosis, and more particularly to a medical device for keratosis used for Kakusatsu or tssis surgery. Disgusting background
- the cornea is located at the starting point of the optical path in visual acuity, and plays the role of light refraction and refraction of A light. Therefore, the angle S is an indispensable tissue for developing good visual acuity.
- FIG. 19 shows a cross section ⁇ fit of the cornea.
- the cornea is composed of 6 to 7 layers of cornea ⁇ ⁇ 51, Bowman's layer 53, corneal occult material 55 that occupies about 80% of the horn S, and Descemet that is the epithelium of endothelial cells. It consists of a membrane 57 and an endothelium 59 consisting of a layer of hexagonal cells.
- the cornea has a thickness of about 500 / im (L), the cornea _h3 ⁇ 451 side force S is the outer layer, and the endothelium 59 side is the inner layer.
- the Bowman's layer 5 3 is the “3 ⁇ 4” of the corneal forbidden material 5 5. Therefore, the separation 6 1 between the angle I ⁇ 51 and the corneal intractable material 5 5 is the most basal part of the corneal epidermis 51 and Bowman. It is located between layers 5 and 3.
- the properties of the cornea _hS51 are as follows. Normally, cells are proliferated actively from the basic play rules toward the surface, and the old cell force on the surface is lost. In other words, in Kakuzuki ⁇ bS51, the new and old cells are active in the active phase. Therefore, wound healing is possible between ⁇ in days, and is performed by extending and covering the corner 51 from around the wound and returning to its original position with an increase in the thickness force S.
- horn-proof material 5 The properties of horn-proof material 5 are as follows. Usually, little change has occurred. Wound healing heals very slowly over a long period of years. In addition, there is a relatively large number of irreversible, ⁇ and there is a tendency that opacity S tends to remain in the wound healing area. 'By the way, eyes or contacts have been used to correct eyesight pain. Kaku MSi ⁇ ⁇ ⁇ # ux is also starting to take place.
- Kakuz ⁇ K ⁇ kai There are two types of Kakuz ⁇ K ⁇ kai: PRK (photorefractive keratectomy), LASIK (Laser in situ keratomileusis) and LASK (Laser epithelial keratomileusis).
- the technique of PRK is as follows. Eye drops are performed and the eyelids are opened by the eyelider. Next, peeling of the corner bS51 is performed only for the purpose of removal using a so-called golf scalpel or a snare. Then, excimer laser light is applied to the exposed surface of the exposed S angled surface 5 5. Excimer laser light irradiates the surface layer and changes its shape, resulting in a change in the corneal refractive power. As postoperative treatment, for example, a therapeutic contact lens is worn.
- the technique of LA S I K is as follows. Eye drops are performed, and eyelids are opened with an eyelider. In this state, the suction ring is called back to raise drowsiness due to the bow i. Then, a ⁇ 3 ⁇ 4 measurement is performed to determine whether or not the force is 65 to 7 OmmHg or more, which is an appropriate target for the incision described below. 'Under such conditions, a so-called microkeratome is used to apply an incising force S between the corneal barrier layers 55. This incision creates a hinged corneal sheet that is connected without being partially incised. The corneal sheet has a thickness of about 15 O ⁇ rn including the horny skin 51 and a corneal force S of about 50 ⁇ .
- LA S and the following are as follows.
- the spices are opened and the eyelids are opened.
- the marking on the corner 3 ⁇ 4 has a circular blade as a whole.
- a part with blade force s, te, nare, etc. is used.
- the alcohol sheet 63 positioned in the corner iron 6 3 is subjected to alcohol S 5 A, and the square sheet consisting of the corner S3 ⁇ 4 ⁇ 3 ⁇ 4 51 A U-process is performed to make the sashimi come out.
- the physiology surface treatment by fe ⁇ R is performed, and detachment of the cornea 51 is started.
- Peeling off the cornea sheet It is delicate for a long time of about 10 minutes because it is transitive.
- a crane is removed to remove the balance of the corners.
- the exposed surface of the cornea substantially 55 is irradiated with excimer laser light, and a change in shape due to the removal of the surface layer causes a change in the angle S ⁇ bending force.
- the thread fek force s is applied to stretch the Kakuzuki EJt3 ⁇ 4 sheet by bow I
- the f ⁇ force s is applied to stretch Kadotsuki ⁇ bS sheet by bow I.
- This restoring condition is also a delicate condition like the above-mentioned peeling condition.
- this square sheet has a cell force fixed by tek, and as a post-operative treatment until the square bg5 i and force s are regenerated, for example, seven medical contact lenses are mounted.
- the corner has the corner Surface angle fl ⁇ t tf, deep surface angle operation.
- the superficial angle S ⁇ Tl is a method of suturing to the patient's cornea by penetrating the corneal surface to a depth of about 200 ⁇ to 300 ⁇ from the surface force.
- Deep superficial keratoplasty is a technique in which the corneal excision is removed or the endothelium and Descemet's membrane are removed and then sewn to the patient's horn.
- the advantages of the PRK mentioned above include the following: The first is that it is very simple. Second, if the sum f3 ⁇ 4 is small, it does not occur even if it occurs. Third, wound healing is physiological because of the high regenerative ability of the cornea ⁇ ⁇ 51.
- the disadvantages are as follows. The first is that the horns ⁇ h 3 ⁇ 4 51 continue to be painful and difficult for 4 days before regenerating, and there is a need for help. It also takes 4 days of wheat to recover. Second, the postoperative angle S3 ⁇ 4 ⁇ lower turbidity S is likely to occur. Third, it is difficult to suppress turbidity under the angle E_b3 ⁇ 4.
- # ⁇ of LA SIK mentioned above includes the following as IJ points.
- the first is that post-operative pain is less than that of the age of PRK, and the recovery of ribs is faster. No. 2
- the lower mix is light.
- the disadvantages are as follows. The first is that the procedure is disgusting compared to the ⁇ of PRK. Second, the range force S is narrower than PRK's: ⁇ . Examples are that the patient's corneal curve is not suitable for a sleepy incision with a microkeratome, and that the width of the patient's eyelids is too narrow to allow a suction ring i3 ⁇ 4g. Third, compared to PRK's: ⁇ , intraoperative and postoperative ⁇ f is more likely to occur, and the ⁇ tends to be more severe. Examples of synthetic fibers include abnormalities of the corneal sheet (abnormal size, abnormal shape, abnormal position, abnormal thickness, perforated holes, etc.). Fourth, compared to the age of PRK, the angle of ⁇
