| Interventions/Control_1 | The patients with corneal perforations receive a single layer patch of the dried amniotic membrane using tissue adhesive in the minor procedure room under topical anesthesia with 2% lidocaine. The dried amniotic membrane is trimmed to the appropriate size and shape before application. A tissue adhesive, 2-octyl cyanoacrylate is applied to the epithelial side of the the amniotic membrane. After drying the perforated site with a cellulpse sponge, the dried amniotic membrane with tissue adhesive is placed over the lesion using forceps. After topical instillation of 0.5 % levofloxacin, a hydrogel contact lens is installed as a bandage. | ||
| Interventions/Control_2 | 2% lidocaine hydrochloride is instilled in the left eye. The dried amniotic membrane is cut to an appropriate size with scissors and tissue adhesive is applied to the amniotic epithelial side of the dried membrane. After drying the leakage site with a cellulose sponge, dried amniotic membrane with tissue adhesive is placed over the leakage site using forceps. A drop of 0.5% topical levofloxacin is instilled and the dried membrane is hydrated. A hydrogel contact lens is placed on the cornea as a bandage. | ||
| Interventions/Control_3 | Revisions of glaucoma filtering bleb. After local anesthesia, the dried amniotic membrane is cut to an appropriate size with scissors and the dried amniotic membrane is inserted through the conjunctival incision underneath the conjunctival bleb. The amniotic membrane is secured with 10-0 nylon. The surface is covered with conjunctival tissues. | ||
| Interventions/Control_4 | (1)After Benoxil ophthalmic solution dropping lotion in the eyes anesthesia, perform washing eyes, disinfection.
(2)After draping, put on ecarteur. (3)Add Xylocaine anesthesia to pterygium body by subconjunctival injection under a microscope. (4)Tear off corneal epithelium close against a front of the pterygium head. (5)Ablate pterygium tissue using a golf sword to the limbus from the head. (6)Ablate episcleral conjunctival epithelium and Tenon pouch enough and denude a sclera and excise pterygium. (7)Douche it in a raw diet of approximately 300 ml after insertion attachment under 3-5min conjunctiva with the microsponge which we soaked with 0.04% MMC enough. (8)The MMC becomes out of an accommodation to use it for a purpose to inhibit an activation (recurrence of the re-pterygium) of the subconjunctival proliferative tissue. (9)Match the stromal aspect of the hyper dry human desiccation cowl (HD cowl) with a sclerotic exposed surface and trim the part of the resection side with ophthalmology cusp sword. (10)After put an HD cowl on the wounded surface, and arrival at sewing did an HD cowl to a sclera, repeat a conjunctiva stump on the top, and sew it up in a 1mm interior position; do. (11)Have top and bottom right and left move an eyeball and check follows and add suturation, if necessary. 1:Is eye movement smooth? 2:Is there not the pull companion whom it is impossible for conjunctiva to do? 3:Does a suture not come off? (12)Steroid subconjunctival injection is provided because of resolution and picks up a contact lens for treatment when corneal epithelium of the pupillary area greatly suffers a loss. |

| Key inclusion criteria | Cause unknown corneal perforation
Traumatic corneal perforation Corneal perforation related to collagen diseases Bleb leaks after glaucoma surgery Bleb failure due to unsuccessful glaucoma surgery <recurrence pterygium> The patients who had a diagnosis of the refractory eyes surface disease that at least one eye (target eyes) packed all the following criteria. In addition, the case same with an eye of the good few visions a binocular a few vision does oculus dexter with an efficacy evaluation eye when both eyes pack all the following criteria.Assume a fellow eye a control. 1) age:The patients who relatively have good Patient 2) overall status of (at the agreement acquisition) 20 years old or older 3)The patients whom pathologic proliferative tissue invaded in recurrent pterygium across limbus. 4)The patients whom it is judged to be available for observation, the testing that conformed to a study enforcement plan and a survey |
|||
| Key exclusion criteria | Acute obvious ocular infectious signs are excluded.
Exp. 1) Acute phase of bacterial, mycotic, or viral corneal ulcers 2) Acute phase of infectious bleb <recurrence pterygium> 1) onset pterygium patient or pseudopterygium patients. 2)The patients whom a doctor judged safely for 2) study period if it was difficult hospital visiting and to come home. 3)The patients who complicate eye infection with 3) activity. 4)The patients who plan the enforcement of eye operations for evaluation eyes effective during 4) study period in (we assume the agreement acquisition study initiation). 5)one eyes are the patients of enucleation eyes or evisceration eyes. 6)For the group medicine of the planned drug (dropping lotion in the eyes anesthetic agent, fluorescein) to use during 6) study period, it is the patients with a history of the drug allergy. 7)The patients (saying that, however, the subjects who do not receive the study drug are possible) who participated in other studies or clinical studies within six months. 8)The patients whom a doctor judged as an object of this study in testing at pregnancy or 9 childbearing patients) agreement acquisition that we might be pregnant or hoped for pregnancy during study period or did not use appropriate contraception for if inadequate. |
