Myopia

Myopia is commonly known as nearsightedness. It means you have difficulty seeing things that are far away. With myopia you can see clearly up close unless you have another condition that affects your close vision, such as presbiopia or astigmatism. Most myopia begins in childhood, but some factors can cause myopia to develop later in life. In adults, myopia can be corrected with laser eye surgery including LASIK.

Myopia and Your Cornea

Your cornea bends light as it enters your eye. A properly shaped cornea focuses that light on the retina. If you are nearsighted your cornea is either too curved or your eye is too long, causing the light to focus in front of the retina. When the light reaches your retina it has started to spread out again and the image is blurry.

Eyeglasses for nearsightedness have concave lenses. This spreads out the light before it reaches the cornea, so it travels farther back in the eye before it is focused.

Laser vision correction reshapes the cornea so it can focus the light properly on the retina.

What Causes Myopia?

Nearsightedness is the most common of all vision problems and affects about 30% of Americans. In the last few decades it has become more common throughout the world. The causes of myopia are uncertain, and the subject has become quite controversial.

Heredity seems to play a large role. Children of myopic parents are more likely to be nearsighted.

Lifestyle may contribute to myopia, as well. Long periods of close work, such as reading, looking at the computer screen, and possibly even watching television, may affect how a child’s eyeball develops as they grow.

It is also believed that a diet high in simple carbohydrates increases your chance of developing myopia, due to too much insulin circulating in the bloodstream (hyperinsulinemia). Hyperinsulinemia is also common in people with type II diabetes and insulin resistance. Late developing myopia is sometimes an early warning sign of diabetes risk and can eventually develop into cataracts.

Complications of Myopia

For most people myopia is an inconvenience, but relatively harmless and easily corrected with glasses or contact lenses. If corrective lenses are too much of a hassle, laser eye surgery is an option as well.

However, myopia can lead to more serious eye conditions, vision loss, and even blindness. People with myopia have an increased likelihood of developing glaucoma and retinal detachment.

Correcting Myopia

Typically, your eye doctor will prescribe glasses and/or contact lenses to correct your vision. Eye exercises can help improve your vision, especially when eye strain from close tasks such as long hours of computer use is a factor.

Laser vision correction can allow you to see clearly 24/7, without the hassle of wearing glasses or contacts.

I Can See Clearly Now: A Guide to Laser Eye Treatment

Once upon a time, the visually impaired had to rely on glasses or contact lenses to see clearly. In the last few decades, however, laser eye correction procedures have restored millions of people’s vision to its former glory.

When ‘laser-assisted in situ keratomileusis’ (LASIK) was developed initially, the laser treatment was primarily intended for those with a specific medial condition, rather than for those simply seeking to avoid the hassles of wearing glasses or contact lenses. Furthermore, in scenarios where the treatment was available to the wider public, the cost precluded most people from venturing down the laser treatment route.

In recent years, however, laser eye surgery has come down significantly in price and is far more widely available than it once was. Furthermore, it isn’t restricted to those with medical conditions – anyone who simply wants to return to perfect 20:20 vision can be considered for it, assuming they are approved for treatment during the consultation period, of course.

In a nutshell, laser eye surgery succeeds by reshaping the cornea in the eye. By changing its form, the path of light through the eye to the retina is altered too, thus replicating the effect that glasses and contact lenses have on the eyes.

The success rate or surgery is good too, with the vast majority of patients enjoying greatly improved vision after treatment. Not everyone will be restored to 20:20 vision – indeed, some people may still have to wear glasses or contacts on occasion. The degree to which surgery helps a person’s vision will depend on the extent of their existing impairment, whilst age is a contributing factor too.

Furthermore, the laser correction process is more or less painless. There may be a slight irritation for a short period in some cases, but laser eye treatment on the whole won’t cause too many problems.

The great thing about laser eye surgery is that its benefits are noticeable more or less instantaneously. So the journey from squinting at the television to enjoying crystal-clear vision on the widescreen plasma can be as little as 24 hours.

Anyone who says that wearing glasses or contact lenses isn’t that much of a hassle may have a good point, but they probably have 20:20 vision themselves.

Indeed, life through a pair of manmade lenses isn’t difficult to adapt to, but there are many little annoyances that go with the territory that makes laser eye treatment all the more appealing. No more smudging, no more messing around with contact lens solution and, importantly, no more squinting at the television when you accidentally leave your glasses on the bus!

The History of Laser Eye Surgery

Laser eye surgery is one of the most valuable medical developments of our lifetime. It has given ophthalmologists a tool to improve sight and in most cases eliminate the need for glasses for good.

Since the new technique was perfected in the late 1980s it has transformed thousands of lives and continues to grow in popularity. This highly specialised procedure allows surgeons to reshape the eye’s cornea correcting the faults that cause blurring of vision. The treatment can be used to correct both Myopia (nearsightedness) and Hyperopia (farsightedness) so the days when thick glasses or contact lenses were the only option to see clearly are gone.

The idea of laser eye surgery has been around since the 1950s and was the result of several different doctors who all played a part in the advance of the procedure. The technique was initially the innovation of Jose Barraquer, a Spanish ophthalmologist who first came up with the idea of cutting into the eye’s cornea to alter its shape.

Twenty years on, the radial keratotomy procedure was developed by the Russian doctor, Svyatoslav Fyodorov, who stumbled upon the important finding when he was treating a boy who had fallen and cut his eye on his glasses. Fyodorov discovered that by shaving off the front layer of the eye the young boy had recovered with better sight than before.

The development of the Excimer laser by a group of scientists from the University of California turned the eye surgery dream into a reality and, because of the inventiveness and dedication of these doctors, the first pioneering surgery was performed in 1989 in Greece. Since then the operation has become a common procedure performed around the globe.

Further developments to the procedure have resulted in two main types of laser eye surgery. Photorefractive Keratectomy, commonly known as PRK, a procedure carried out on the surface of the eye, and LASIK surgery, which differs because of the incision made to the surface of the eye and the laser treatment that is applied to the corneal tissue beneath.

Because of the delicate nature of an eye the operation needs to be performed with great care and, although the technology sounds complicated, in the hands of a qualified practitioner it is a relatively straightforward one. In general, the operation takes around 30 minutes although the actual laser treatment can take as little as a minute.

The technology and development of laser eye surgery has resulted in a simple painless procedure with a very quick recovery time. Today the surgery boasts a 95% success rate with most patients enjoying full 20/20 vision which is a testament to the brilliance of the doctors who invented the ground breaking operation.

Everything About LASIK Surgery

The most popular eye surgery today is LASIK surgery. It is efficient, fast, very gentle and with few complications. For most people the LASIK surgery can help them no matter if they are nearsighted, farsighted and have astigmatism.

LASIK technique is a further development of the older PRK laser surgery. Both operations are done by removing the outer cornea layer, so the laser can remove the tissue. The difference is that while the PRK eye surgery scrapes the outer layer of the cornea away, the LASIK surgery will cut a flap in the cornea that can bend. After the surgery the flap will be put back again.

The operation itself takes only a few minutes and is completely painless. The eye will be anaesthetized right before the surgery, and most people will not feel any pain at all. Subsequently the flap will be cut and the laser surgery can be made.

The actual operation only takes between 30 seconds and two minutes. A laser specially designed for operating in the eye’s sensitive tissues will be used. After the operation the flap is put back in place.

It is possible to leave the operating room right after the surgery. The eyes may sting a little bit, so it is advised to rest for the rest of the day. A nap can also help.

For most people the sight will have improved right after the operation. It will then stabilize over the next weeks.

After the eye surgery the eyes can feel a little dry. It is therefore recommended to drip them with a little salt water.

All studies indicate that a permanent sight improvement is provided by the LASIK operation. And previous bad eyesight will not return again. But a possible, natural change of sight in the future is not possible to prevent by the operation. So the surgery should not be done before the sight is stable.

The age-related long-sightedness that all people will experience can also not be prevented by a LASIK operation.
