How do I know if I am suitable for Trans PRK ?
- You will need to go through an in-depth pre-surgical evaluation. Eye surgeons and optometrists will check your eyes thoroughly. Some of the factors that determine your suitability for Trans PRK are:
- Corneal shape
- Corneal thickness
- Any pre-existing eye conditions such as glaucoma, cataracts, etc.

What is Myopia?
Nearsightedness, or myopia, is a vision problem experienced by up to about one-third of the population. Nearsighted people have difficulty reading highway signs and seeing other objects at a distance, but can see for up-close tasks such as reading or sewing.
Did you find this useful?
What are the signs of Myopia?
Myopic people often have headaches or eyestrain, and might squint or feel fatigued when driving or playing sports. If you experience these symptoms while wearing your glasses or contact lenses, you may need a comprehensive eye examination as well as a new prescription.
Did you find this useful?
What causes Myopia?
Myopia occurs when the eyeball is slightly longer than usual from front to back. This causes light rays to focus at a point in front of the retina, rather than directly on its surface. Nearsightedness runs in families and usually appears in childhood. This vision problem may stabilize at a certain point, although sometimes it worsens with age. This is known as myopic creep.
Did you find this useful?
What is the treatment of Myopia?
Nearsightedness may be corrected with glasses, contact lenses or refractive surgery. Depending on your vision problem, you may need to wear your glasses or contact lenses all the time, or only when you need distance vision, like driving, seeing a chalkboard or watching a movie. With myopia, your prescription is a negative number. The higher the numeral, the stronger your lenses will be. Refractive surgery can reduce or even eliminate your need for glasses or contacts. The most common procedures are performed with an excimer laser. In photorefractive keratectomy, or PRK, the laser removes a layer of corneal tissue, which flattens the cornea and allows light rays to focus closer to or even on the retina. In laser-assisted in situ keratomileusis (LASIK) ? the most common refractive procedure ? a flap is cut through the top of the cornea, a laser removes some corneal tissue, and then the flap is dropped back into place. Also, at Magrabi we provide the latest techniques to treat Myopia like LASEK and EPILASIK. You check our Vision Correction Corner and review the different options.

What is hyperopia?
Hyperopia, or farsightedness, is a common vision problem, affecting about a fourth of the population. People with hyperopia can see distant objects very well, but have difficulty seeing objects that are up close.
Did you find this useful?
What are the signs of Hyperopia?
Farsighted people sometimes have headaches or eyestrain, and may squint or feel fatigued when performing work at close range. If you get these symptoms while wearing your glasses or contact lenses, you may need an eye exam and a new prescription.
Did you find this useful?
What causes hyperopia?
This vision problem occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is shorter than normal. Many children are born with hyperopia, and some of them "outgrow" it as the eyeball lengthens with normal growth. Sometimes people confuse hyperopia with presbyopia, which also is a difficulty in seeing up close, but has a different cause.
Did you find this useful?
How is hyperopia treated?
Farsightedness can be corrected with glasses or contact lenses to change the way light rays bend into the eyes. If your glasses or contact lens prescription begins with plus numbers, like +2.50, you are farsighted. You may need to wear your glasses or contacts all the time, or only when reading, working on a computer, or doing other close-up work. Refractive surgery, such as LASIK or CK (Conductive Keratoplasty), Intra-corneal Lenses and Lens Implants are all options for correcting hyperopia. They may reduce or eliminate your need to wear glasses or contact lenses. Check our Vision Correction corner to see what's there for your case. You can find this whole range only in Magrabi Hospitals & Centers.

What is Astigmatism?
Astigmatism is the most common vision problem among people. Sometimes incorrectly called a "stigmatism," astigmatism may accompany nearsightedness or farsightedness. It's caused by an irregularly shaped cornea and is corrected with eyeglasses, contact lenses or refractive surgery.
Did you find this useful?
What are Astigmatism signs?
If you have only a small amount of astigmatism, you may not notice it or have just slightly blurred vision. Sometimes uncorrected astigmatism can give you headaches or eyestrain, and distort or blur your vision at all distances.
Did you find this useful?
What Causes Astigmatism?
Astigmatism occurs when the cornea is shaped more like an oblong football than a spherical baseball, which is the normal shape. The oblong shape causes light rays to focus on two points in the back of your eye, rather than on just one. Many people are born with this oblong cornea, and the resulting vision problem may get worse over time.

How is Astigmatism treated?
Astigmatism can be corrected with eyeglasses or contact lenses. Many people with astigmatism believe that they can't wear contact lenses, or that only rigid contact lenses (RGPs) can correct astigmatism ? but this is no longer true. Now there are soft lens designs that correct astigmatism; they are called toric contact lenses. Toric lenses have a special correction built into them and may also contain a prescription for nearsightedness or farsightedness if you need it. While soft torics work well for many people, if you have severe astigmatism, you'll likely do better with RGP contacts or eyeglasses. Your eyecare practitioner will advise you. Depending on the type and severity of your astigmatism, you may also be able to have it corrected with refractive surgery. Discuss with your eye doctor which procedure is best to correct your astigmatism, and review your options in our Vision Correction corner .

What is Presbyopia?
During middle age, usually beginning in the 40s, people experience blurred vision at near points, such as when reading, sewing or working at the computer. There's no getting around it ? this happens to everyone at some point in life, even those who have never had a vision problem before. Currently an estimated 90 million people in the United States either have presbyopia or will develop it by 2014. This is generating a huge demand for eyewear, contact lenses, and surgery that can help presbyopes deal with their failing near vision.

What are Presbyopia signs?
When people develop presbyopia, they find they need to hold books, magazines, newspapers, menus and other reading materials at arm's length in order to focus properly. When they perform near work, such as embroidery or handwriting, they may have headaches or eyestrain, or feel fatigued.

What causes Presbyopia?
Presbyopia is caused by an age-related process. This is different from astigmatism, nearsightedness and farsightedness, which are related to the shape of the eyeball and caused by genetic factors, disease, or trauma. Presbyopia is generally believed to stem from a gradual loss of flexibility in the natural lens inside your eye. These age-related changes occur within the proteins in the lens, making the lens harder and less elastic with the years. Age-related changes also take place in the muscle fibers surrounding the lens. With less elasticity, the eye has a harder time focusing up close. Other, less popular theories exist as well.

What is Lasik success rate?
Experience has shown that laser vision correction has been overwhelmingly successful in reducing myopia, astigmatism, and hyperopia. Overall, more than 98% of patients do not need to wear glasses after being treated. These patients are able to drive comfortably, play sports, or just watch TV without the hassle of corrective lenses. The success rate is directly related to the skill of the surgeon, quality post-operative monitoring, and the type of laser utilized.

Are Lasik results permanent?
Magrabi Hospitals & centers has been performing laser eye procedures since 1991 and we know that patients from these early days still have great unaided vision today. However, it cannot prevent the eyes' natural ageing process. A small number of patients may require re-treatment (or 'enhancement') in order to achieve the best overall result and if this is recommended, it is usually within the first year.

Should I bring someone with me?
Yes. At your consultation we may instill eye drops to dilate your pupils. This can cause your vision to become slightly blurred for a few hours after the consultation, and we strongly advise against driving yourself home. Likewise, on the day of treatment, your vision will take a while to stabilize and you will not be able to drive yourself home. Please bring someone with you to both your consultation and your treatment appointments to accompany you home.

When can I return to work after Lasik?
It is generally advisable to rest and stay home from work the day of treatment and possibly the first day following laser vision correction. By the end of the second day, most patients are able to return to work and resume normal activities, including sports. The risk of infection is low; however, patients must be careful for the first week to avoid certain activities like swimming and gardening.

What are the Lasik risks?
Based on a decade of studies with the laser and a century of research on corneal healing, most experts in the field feel confident that nothing will change long-term. There has been no evidence whatsoever of any long-term problems to date. With LASIK, because the epithelium is not removed and Bowman?s membrane is not disrupted, a variable healing process is not introduced, long-term results are much more predictable.
