The causes of cataracts are divided into three types: congenital, senile and secondary. Congenital genetic disease, chromosomal variation, fetal infection; Old age is the most common cataract in the elderly; Secondary, steroid drugs, metabolic diseases such as diabetes, thyroid disease, eye diseases such as glaucoma, retinal pigment lesions, and trauma. Treatment of cataracts is not dependent on eye drops, qigong, health food or injections hong kong scholarships, etc... Proper and effective treatment should be used to remove turbidized and aged crystals and implant them in artificial lenses.
Ultrasound emulsification minimally invasive surgery (Phacoemulsification)
Past the traditional cataract surgery, the doctor in corneal incision wound around 11 to 15 mm, using the instrument capsule to open a small hole in front of the crystal, take out the crystal core, add artificial crystal, sew after 5-7 needles, 100-100 degrees astigmatism may occur after surgery. Nowadays a new generation of ultrasonic emulsification, minimally invasive surgery under local anesthesia or surface anesthesia and surgery to aging and opacity of the lens, the doctor will through the incision is less than 2.2 mm, in a head the size of a tool such as pen, to break up the cloudy crystal, then suck it, after the removing of the cloudy crystal, doctors will use special injector implanted an artificial lens, to replace the old crystals, focusing the light in the retina, the wound from 2.2 to 3.0 mm, without stitches or only seam a needle, fast recovery, reduce infection and complications, reduce caused by needle and thread to change curved cornea astigmatism, operation time about 15 minutes, can go home on the day of surgery. After the operation, it was clear that the vision was clear and the effect was obvious. It was not necessary to wait for the cataract "mature" to perform the operation Serviced apartment Causeway Bay, so that the patient could regain clear vision at an early date. In contrast, too familiar cataracts can double the risk of surgery and greatly increase the risk of surgery.
Before cataract surgery, eye examination, physical condition assessment, eye measurement, selection of artificial crystal and degree, measurement of corneal radian, measure the length of the eye axis, calculate the number of artificial crystals. Medical staff will ask patients for information on past medical records and hospitalization, which will help them to provide appropriate care for their patients. Before the operation, the patient needs to wash his hair, take a bath, remove her makeup, and wash the armor. No diet should be banned. Long-term drug users should take medication or follow the doctor's special instructions. The operation will be performed under local anesthesia, and it will remain awake during the procedure and will not feel the pain. During the operation, need to lie in bed, the head is fixed, the governed the eyes will not see things, but you feel the strong light, the nurse will accompany the left and right sides, let patients at ease, comfortable, and try to relax.
Shampoo and shower the day after the operation start business in hong kong, avoid by all means avoid water into the eye and recumbent or press the eyes, use eye drops or medication as directed by your doctor, need to wear the transparent eye mask in the evening, in order to rub your eyes with his hand when sleeping, can undertake everyday activities as usual.
What is traditional single focal length artificial crystal?
The simple refraction principle is used to provide a single focus (usually long distance). After surgery, the patient needs to wear the glasses to watch the proximity objects and affect the quality of life.
What is "optical zoom"?
Patented and special optical design, which provides the most efficient distribution of light and produces multiple focal vision, providing a focused ability from far to near. An operation can simultaneously solve the cataract and the old flower, provide the full range vision, have the opportunity to say goodbye to the glasses. This technology has obtained the United States food and drug administration (FDA) approved, the FDA's clinical data show that more than eighty percent of users said no need to wear glasses, and ninety-four percent of users satisfied with the effect after the surgery, will make the same choice.
What is "laser cataract surgery"?
"Laser cataract surgery" exclusive use laser cutting can create a near-perfect circle in front of the crystal capsule membrane, to put the correct artificial crystal, the multifocal lenses implanted and astigmatism artificial crystal is particularly important. Compared with "ultrasonic emulsification cataract surgery", "laser cataract surgery" USES less ultrasonic energy and effectively reduces the loss of corneal endothelial cells during the operation. Excessive loss of corneal endothelial cells may have serious or direct effects on vision, and loss of corneal endothelial cells cannot be restored.
Cataract surgery has been toward the vision correction function in the direction of development, by the past cure cataract, to now have both vision correction function, therefore, selection of patients life need artificial crystal, the patient had a profound influence on life after surgery.
