Regarding cornea relative nearsightedness number

Regarding cornea relative nearsightedness number oakley minute 2.0 of degree Gao Erran the daughter-in-law> curtain cheek lu ? coat ? ASIK is also restricted, but regarding cornea petal enough thick high nearsightedness patient, first choice LASIK is good. under 3 accurate molecular laser epidermis the home position cornea rubs inlays technique LASEK, is the PRK surgery's improvement technique type. With the laser or the low concentration ethyl alcohol immersion cornea field of operation, makes an epithelia corneal petal, under the laser cutting epidermis petal organizes, when after epithelia corneal petal replacement, must cover piece of contact lenses in its surface. After LASEK surgery, the ache compares PRK to reduce obviously, in addition the petal is thin, may use in the cornea thickness being relatively thin, the pupil big patient. LASEK makes the cornea petal without LASIK the complication, after reducing the PRK surgery, the epithelia corneal cicatrization time, reduced the ache response and the opacity of the cornea haze degree, but in surgery epithelia corneal petal breakage and dropsy and PRK with, moreover the surgery back sight strength restores and the refraction steady rate is slower than LASIK. Therefore is mainly suitable for the cornea is thin, the professional characteristic easy to have the eye flesh wound to cause the patient who cornea petal shifting or other are not suitable carry on LASIK. The farewell nearsightedness, the reappearance clear view, becomes the now fashion. But, how to choose the ideal surgery way, the advanced surgery equipment and high level surgery doctor makes some shortsighted patient to feel the puzzle frequently. The laser surgery technique's-like choice is also the refraction care topic, most recent on several on a refraction academic research board, the experts has made the exchange on nearsightedness's surgery's choice question, speaking of the laser surgery, the nearly all expert opinion is consistent: At present speaking of the overwhelming majority nearsightedness patient, LASIK is the first choice which the laser surgery treats. Only then few cornea thin number of degree high nearsightedness patient in makes in the LASIK surgery condition not too ideal situation, may consider that chooses LASEK. The overseas situation approximately is also same. According to Europe, the US two become known the cataract  oakley minute and the refraction surgery association ESCRS, ASCRS the most new investigation demonstrated: LASIK was still the refraction surgery which the whole world most receives welcome. Specifically speaking, the LASIK surgery and LASEK compared retained on the cornea the cerebral cortex and the first tension level, conformed to the cornea original physiology condition, after the technique, was not obvious ill, before the overwhelming majority patient second day then achieved or the close technique corrects defects of vision best, after the technique, the second day then went to work, applies drugs does not surpass in January, basic non-retroversion phenomenon. Because before LASEK the surgery has damaged on the cornea the cerebral cortex and has excised the cornea, the tension level, triggers the epithelia corneal – matrix compound repair to respond inevitably, easy to cause the cornea organization proliferation to present the shortsighted retroversion and the cornea fog muddy phenomenon. LASEK does not use the micro keratome, therefore the surgery cost is low. Because LASEK the development time is short, the surgery applicable scope is quite narrow, in the global scale the surgery number are few.
