Laser Eye Surgery Introduction

Laser eye surgery is an effective treatment for poor vision and other visual impediments, utilising a high powered laser to slightly alter the shape of the cornea and thereby correct problems with sight. This surgery can produce long term results and in some cases eliminates the need for glasses or contact lenses. This section gives an in-depth look at issues and important questions about the surgery, a few of which are outlined below.

How does it work?

Poor eyesight is caused by problems with the lenses in the eyes: in short-sighted (myopic) people the lenses are excessively thick and strong, while long-sighted (hyperopic) people have lenses that struggle to thicken and strengthen. In both cases the light rays are prevented from reaching the eyes in the right way, either by the lenses focusing too quickly or too slowly.

Laser eye surgery involves holding the eyes open and cutting into the cornea using either the laser or a microkeratome blade. This creates an opening through which the high powered laser can reshape the corneal tissue with precise accuracy to change the way the lenses work. The cornea needs no prodding or stitching to become reattached.

Who can benefit from laser eye surgery?

Short and long-sightedness are treatable with laser eye surgery, as is astigmatism which distorts the appearance of objects at all distances. Presbyopia, the lack of focus on nearby objects that develops in late adulthood, has also been successfully corrected. More serious conditions such as glaucoma are occasionally treated with laser eye surgery, but this will depend on individual circumstances.

There are also a number of physical reasons that can render a patient unsuitable for laser surgery, and prior examination by a professional can alert you to any such factors. Autoimmune diseases and diabetes are often inappropriate for surgery, and general fitness also plays a role in determining suitability.

How effective are the results?

While the results are impressive for innumerable people, absolutely perfect vision should not be expected. The surgery is very effective and produces permanent changes to the eyes, but this does not stop the natural aging process from further altering your vision over time. It is crucial to be realistic and talk to a professional about the expected outcome before undergoing laser surgery. Experts recommend that this treatment be considered after major changes in vision, and patients over 40 years of age should expect to wear reading glasses after surgery.

How much does it cost?

Cost is an important consideration for most people because laser eye surgery is rarely covered by health insurance plans. The prices vary greatly between providers and many factors can affect the cost. Accredited specialists will quote a price per eye, and these can reach past $2000 each. The cost is often lower for procedures using the microkeratome blade.
