PRK Vs Lasik
More than 100,000 people in the United Kingdom use means of laser treatment for eyes, every year. Surgery can help in correction of vision by cutting cornea and giving right shape of the eyes. Between 80 and 98 percent of the treatments improve the view as no longer glasses or contact lenses needed.
There are currently two popular methods of laser eye surgery. Most often in the form of a laser treatment is Lasik. In Lasik, a small cut is to create a corneal cap. Laser treatment can be. May vision loss from 20 to 30 second during the procedure. LASEK the epithelium is removed before the cornea with a new laser. Treatment of eye laser takes about 15 minutes total.
For many patients is a much LASEK LASIK treatment is desirable. After LASEK, the patient experience of pain May mäßig about 24 hours after the operation. The high light sensitivity is also often regarded as the first couple of days and you will be asked to wear sunglasses outdoors during the last three months. Blurred vision May or a week and lasts about one month before the point of view of patients’ seat ‘and the final results of surgery are known. Lasik with the treatment, there is very little postoperative discomfort and the results of surgery are obvious much more quickly. Vision should be much less than in the first period after LASEK unclear and should reassure blurriness within 48 hours. Lasik patients will probably be able to see the day after the treatment.
In a minority of patients, we recommend more Lasik PRK LASEK or if the patient is a thin cornea. KPR was the forerunner LASEK and works with an excimer laser to remove a thin layer of cells on the surface of the cornea with the reform of the eye. No cutting is necessary. The main difference between PRK, LASEK and PRK, that the cells be removed and the epithelium will grow after the treatment, which for several days. In LASEK, the epithelium is removed with a low-alcohol solution, and then immediately after the surgery. A contact lens for several days, in order to keep the job.
KPR has been more than ten years and until now does not seem to be the long-term effects. LASEK is also known as low risk. This is in large part because of the cutting unnecessary surgery in one of these laser treatments for the eyes. Lasik despite its advantages, as the risk of laser eye surgery. The possible complications include corneal ectasia, where the accumulation of pressure occurs after the weakening of the cornea. It also requires a surgical intervention to a rapid degeneration in May, which would otherwise occur in the eyes.
The effects of laser eye surgery is permanent, but the process can not prevent a further deterioration with age.
Laser Assisted Sub-epithelial keratectomies (or LASEK) is a method for laser surgery is performed to correct this problem of light refraction of the cornea. It was designed specifically for people with astigmatism, hypermetropia (view) and the short-sightedness (myopia). LASEK is a technology that combines laser in situ keratomileusis supported (LASIK) and Photo refractive keratectomies (KPR), with the hope of reducing the incidence of complications of LASIK with flap. It is especially useful for patients whose cornea is too thin for LASIK.
