The expert group of laser pointer holds the high hope

 The expert group of laser pointer holds the high hope for the market value of laser pointer .
The color of light from the light wavelength (or frequency) decision. A certain wavelength corresponding to the certain color. Wavelength distribution of sunlight in the range of about 0.76 microns to 0.4 microns, the corresponding color from red to purple, 7 colors, so the color of sunlight alone. Single-color light emission as monochromatic light source that emits a single wavelength of light. Such as krypton lights, helium lights, neon, hydrogen lights are monochromatic light sources, only a certain color of light emission. Although monochromatic single wavelength light source, but there is still a certain distribution. If only transmit red neon, color is very good, known as the highest monochromatic wavelength range of the distribution is still 0.00001 nm, so the neon red light, if carefully identified dozens of red still contains . Thus, the optical radiation of wavelength range of the more narrow distribution, the better the color. 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 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 laser pointer in the summary meeting of 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.
