Lasik Eye Surgery Procedure
The Lasik eye correction process is the most popular refractive surgery (surgery that is designed to improve vision) procedure these days, not least because there is usually very little pain and lasik patients normaly achieve improved vision with 24 hours. The preparation for the operation will take about an hour, after which the eye is anesthetized with topical eye drops, and is then held open by a special instrument called a speculum. The lasik surgeon cuts a thin flap in the cornea (the front of the eye) either using a blade called a microkeratome or a laser. The next step in the lasik eye correction process is to fold this "corneal flap" back then then use a very precisely-controlled laser to remove tiny bits of tissue from the cornea and thus change its shape. The complete opertion takes about 15 minutes, and the whole process from preparation to completed lasik eye correction is normally about an hour. Both short-sighted and far-sighted people can be helped by lasik eye correction, as can those with astigmatism (see the separate articles below).

- Prk vs Lasik – which Option is Best for You?: If you’re contemplating laser eye surgery, one of the options you need to consider is PRK vs Lasik , and decide which one is better for you. While Lasik is currently the most popular form of laser eye surgery, it is not necessarily the right solution for everyone wanting to move away from the inconvenience of corrective glasses or contact lenses. PRK vs Lasik – quick summary: Lasik is less painful; The recovery time is shorter after lasik; There is no corneal flap – so there is no chance of flap complications ; PRK is more suitable for people involved in activities or sports that might result in some kind of impact on the eye (boxing, martial arts); The PRK procedure can be used on corneas that are too thin for Lasik; PRK vs Lasik – from Scalpel to Laser PRK is an improvement on the original process, which was called radial keratotomy (the RK part of PRK). In this procedure surgeons used a scalpel to make a radial pattern of fine cuts in the cornea to improve a patient’s vision. The obvious risk was that the procedure relied completely on the eye surgeon’s experience, skill – and steady hands. The newer [...]
- What You Need to Know About the Lasik Procedure: You need a great deal of information to help you make the right decisions before undergoing a lasik procedure. Here are some crucial questions you should ask, so that you understand what to expect before, after and during lasik eye surgery. You’re almost certain to have a long talk up front with your Lasik surgeon or your doctor, and that’s the perfect time to gain a better understanding of what’s involved in a lasik procedure. If fact, a key part of any examination before surgery should be an explanation of what to expect. Are you a good candidate for a Lasik procedure? This should probably be your first question, and a good examination will provide the answer. Make sure you tell your doctor about your general state of health and the history of any eye problems you experienced or still experience. Anyone under 18, anyone is who pregnant or nursing or who will be within six months, is also not a good candidate. Will degenerative eye diseases disqualify you? Poor candidates increase the risk of an unsatisfactory outcome to a lasik procedure – neither you nor your surgeon will be keen to take that sort of chance. Will a Lasik [...]
- Is Wavefront Lasik Worth the Extra Cost?: Wavefront technology is not only used in wavefront lasik eye surgery itself, but also in the initial diagnosis. This diagnosis produces a 3-D map that can be used to guide the laser very accurately during the actual surgery. Studies have compared wavefront lasik to conventional lasik, and show that anyone undergoing wavefront guided laser eye surgery is more likely to achieve 20/20 vision without glasses or contact lenses than those treated without wavefront technology. With wavefront lasik there is less chance of suffering from problems such as a loss of visual quality, a loss of contrast sensitivity and problems with night vision. All eyes have some sort of imperfection, called an aberration. It is the degree of aberration that matters. Wavefront Lasik Improves Chances of Seeing Well Lower-order aberrations are the ones you hear about most often – myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. There are also higher-order aberrations, which account for about 15% of eye problems, and have exotic names such as coma, spherical aberration and trefoil. These aberrations cause problems that can include difficulty seeing at night, halos, issues with glare and blurred vision, and account for about 15% of eye problems – and wavefont lasik plays an [...]
- How the Lasik Monovision Option can help Aging Eyes: The lasik monovision option, one of the tools in the lasik eye surgery armoury, is the latest weapon in the widespread battle against presbyopia. Presbyopia? Well, if you’re over 40 the odds are you suffer from it already. Even if you’re younger, you will probably will suffer from it eventually, because it is a completely natural process. The FDA recently approved the use of the VISX CustomeVue Excimer Laser to correct presbyopia – a significant step forward, as the process is generally seen as a good option for anyone older than 40. Most people gradually start to lose the ability adjust the lens of their eyes so that they can focus equally well on objects that are near or far. Often they end up needing glasses to correct this problem. These glasses are usually reading glasses, although sometimes the reverse occurs. People who can read well without glasses can eventually find they need help for distance vision. And sometimes you need two sets, one for near and one for far. Or you combine them, and get bifocals. Some people even need trifocals. This gradual loss of the ability to focus well at all distances is called presbyopia. It usually happens [...]
- Lasik Eye Treatment – What Conditions Can it Help?: When you’re considering Lasik eye treatment it is important to keep a firm grip on reality. In the early days of Lasik eye surgery there were promises of complete freedom from corrective lenses, either eyeglasses or contacts. These days a much narrower range of eye problems is considered viable for Lasik eye treatment . What you should actually expect is less dependence on corrective lenses, not their elimination. Lasik Eye Treatment – the Three Major Conditions The three major conditions that Lasik eye treatment can usually handle successfully are myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. If you are nearsighted, light from somethimg some distance away is focused in front of the retina (the back “screen” of the eye), rather than on the retina itself. This means you can easily see something that is close, but have problems with things that are further away. The reverse happens with hyperopia. The light is focussed behind the retina instead of on it, so you can clearly see objects some distance away, but have problems with closer ones. With astigmatism, there are problems either with the shape of the cornea (the very front portion of the eye)or the lens itself. Light reaches two focal [...]
- Lasik Eye Surgery Procedure: A Lasik eye surgery procedure really has one objective – to lessen your dependence on glasses or contact lenses. Godsend though they may be, glasses and contact lenses can be an irritant, especially for active people. While there are no guarantees, for most people Lasik surgery will greatly reduce or even completely eliminate the need for corrective lenses. How the Lasik Eye Surgery Procedure Works After the Lasik eye surgery procedure, you may be able to forget about losing lenses in contact situations. You won’t have to worry about forgetting where you put your eyeglasses, or having them fog over with perspiration because you’re exercising hard. Lasik eye surgery permanently changes the shape of the cornea, which is the clear covering of the front of the eye. The cornea’s role is to help focus light on the retina. If its shape is not perfect, the image on the retina can be blurred because it is out of focus, or distorted. Lasik Eye Surgery Procedure Corrects Refractive Errors Bending and focusing light is also called refraction, and these particular eye problems are called refractive errors. The main types are myopia (nearsightedness), hyperopia (farsightedness) and astigmatism (distorted images). Lasik eye surgery is [...]
