The technical problem analysis of led flash light

Today, the rapid development of science and technology, medicine has also been a surprise to the human one, excimer laser surgery worldwide, 40 million patients with myopia of the same choice. But recently, many patients ask to question the side effects of excimer laser surgery. So what exactly does the existence of this side effect? New Vision Eye Hospital following Quanzhou "Sino-US cooperation in height, correction of high myopia clinical base," chief expert Professor Cai Guoling, combined with their more than 36,000 cases of laser treatment of myopia surgery experience for everyone to do the next detail. The expert group of green laser pointer will carry out the technical problem analysis of led flash light .
Excimer laser treatment of myopia correction is the ideal high-tech projects, the set of computers, lasers, biomedical engineering technology, and the use of excimer laser beam energy is high, penetrating very weak, cutting accuracy and reproducibility of the characteristics of accurately cutting the corneal layer of the organization, reducing refraction in order to achieve the purpose of correction of myopia, the operation of the surrounding tissue and no effect on the deep structure of the eye, with the whole Qi Guangjie cutting, high precision, forecasting strong, good stability, great complications less so, in patients with surgery without pain, without hospitalization, does not affect the normal work and life, is the ideal treatment of myopia surgery program. Already has 40 million myopia surgically remove the glasses. A well-known health magazine reporter had the "excimer laser have side effects?" The technical problem analysis of green laser pointer will be finished in the afternoon.
Interviewed Professor Cai Guoling, Professor Cai Guoling replied: "No surgery is not an absolute one hundred percent secure, even if the correction as Lasik surgery, already have very high security, and accuracy, there are inevitably has its dangers, but since the new vision of Quanzhou Eye Hospital to build hospital for treatment of myopia has nearly 40,000 cases of myopia surgery success stories record: never in one case of blindness caused by the example of serious complications is 0! and most of cure or recovery with the wound to improve, and only a few more some degree of visual effect, so patients must have a reasonable expectation of surgery, and risk awareness. " After the acceptance, the summary meeting of green laser pointer will be held.
Some patients appear to do the side effects of excimer laser? Photophobia: after surgery three to six months, increased sensitivity to light, but many will gradually disappear after 6 months, very few cases will continue. Correction of deficiencies or over-correction: residual myopia after surgery, or more than the expected degree of correction into hyperopia, is the most common side effects, as the case may be re-stabilized laser correction degree. Glare or double vision: early surgery is more common, especially at night will have a pupil larger than the majority will gradually disappear, only a small part of it will continue. Corneal flap folds or displacement: only in LASIK, may be due to trauma, can cause irregular astigmatism affect vision, surgery may be re-paved. Epidermal healing: more common in PRK, contact lenses can be therapeutic and artificial tears to help recovery. The company will make the improvement actions of green laser pointer in the summary meeting of green laser pointer.
Corneal opacity: only occur after PRK, with the higher degree of personal physical fitness and a positive correlation correction, 1-3 months after the most obvious point of steroid eye drops to be controlled, then most will slowly fade. Surgery complications: corneal flap cutting is bad in most, if not completely cut or cutting is not smooth; reset as long as the corneal flap can be restored, three months after reoperation. Impurities under the skin flap or invasion: a minor who does not affect vision, severe corneal flap to be opened to remove. Infection: a result of surgery or postoperative dirty, so that the wound to bacteria infection, the probability is very low, as long as early detection, most available medications. Some foreign experts of green laser pointer will attend the meeting.
