To find out if you need to get eye correction, first read your eyeglass prescription carefully. The first number on your prescription indicates the curvature of your cornea. A negative curvature indicates nearsightedness, while a positive curvature indicates farsightedness. The closer this number is to zero, the less severe your prescription will be. The second number on your eyeglass prescription indicates the level of astigmatism. Values between zero and 2.50 are considered mild to moderate, while values higher than 2.50 are considered severe. 시력교정술
Laser vision correction
Laser vision correction is a popular procedure to correct eye problems. The procedure can improve your vision and eliminate the need for prescription visual aids. However, you should be aware of potential side effects before undergoing the procedure. You may experience eye irritation and infection, which can be treated with antibiotics. Some people may also experience corneal bulging or thinning, resulting in blurred vision.
If you are a Service Benefit Plan member, you can contact a provider directly to learn more about the procedure. During this consultation, the provider can evaluate whether you are a good candidate for laser vision correction. After your consultation, your doctor can schedule an appointment to correct your vision.
LASIK
LASIK is a procedure that uses a laser to correct the irregular shape of your cornea. This misalignment causes light to focus on your retina, resulting in blurry vision at varying distances. This surgery works by permanently changing the shape of the cornea, making it possible for you to see without glasses or contact lenses.
Although LASIK is a popular procedure for vision correction, it is not without its risks. A recent study in the JAMA found that a higher percentage of people have complications than previously believed. Aside from vision loss, patients may experience glare or halos. In addition, 43 percent reported new visual symptoms after their LASIK surgery.
PRK
Patients undergoing PRK eye correction can expect to experience pain and minor irritation for the first 24 hours following the surgery. However, these side effects are not severe enough to limit patients from performing everyday activities. A special bandage is placed over the patient’s eye for several days after the PRK procedure to help the surface of the cornea heal. This bandage is removed once the surface has healed. Patients can expect functional vision for the first few days after the surgery, although some may experience blurred vision or sensitivity to light. Patients who have PRK eye correction will be prescribed pain medication and eye drops to help with recovery and pain.
Before having PRK eye correction, patients should discuss their vision needs with their surgeon. For instance, someone may wish to have clear distance vision while another person may want to improve night vision. The patient should also share their expectations for the procedure and what they hope to get from it. It is important to discuss the specific vision outcomes you desire for the procedure so that you don’t end up disappointed with the results. 렌즈삽입술
EpiLasik
EpiLasik eye correction is an excellent alternative to traditional LASIK eye surgery. It uses a bladeless laser to reshape the cornea and correct vision. It has a low risk of serious complications and has many advantages. This procedure is popular with patients who are not candidates for traditional LASIK surgery.
Patients usually see a significant improvement in their vision immediately following the surgery. About 75 percent of patients reported 20/40 vision in one day. However, recovery time is much longer than with traditional LASIK.
Excimer laser
The excimer laser eye correction procedure is an effective treatment for short-sightedness, nearsightedness, and astigmatism. The excimer laser focuses light on the retina in the back of the eye, thus correcting refractive errors. However, this treatment does not work for presbyopia, an age-related condition.
Excimer lasers differ in their technologies and the amount of tissue they can remove. In most cases, the excimer laser removes very small amounts of tissue on the surface of the eye. These amounts are usually less than 0.25 microns, which is a thousandth of a millimeter. Besides, the excimer laser emits very low amounts of energy and does not cause damage to the eyes.
