In addition to making the cornealflap, new developments have extended use of the IntraLase into the realm of therapeutic applications. This means that patients requiring a corneal transplant can now be operated on with a laser using a process called IEK, or IntraLase Enabled Keratoplasty.

The cornea is a very thin curved tissue on the front of the eye which functions like a lens. We can often use a laser to reshape the cornea and eliminate the need to wear glasses. However, there are many people with corneal problemswhich cannot be correctedvia laser. A corneal transplant may correct the problem by putting a new, clear window in place, but the healing process is prolonged, and there is often a considerable amount of astigmatism afterwards.

This is where IntraLase

Are these for everyone? No -- though they were initially developed first for the correction of near-sightedness, they didnt pan out for this group of patients.However, a doctor in France suspected they might be good for patients with a condition called keratoconus. You will remember that the cornea is the clear dome on the front of the eye that functions as its major lens. This allows us to use lasers to correct near-sightedness, farsightedness and astigmatism. If you have keratoconus, your cornea is distorted and vision is blurry. While this is often correctable with hard contact lenses, the lenses are uncomfortable and dont correct the vision all that well.

Thank goodness, then, for Intacs!

The answer, inquisitive reader? Lots! Perhaps even oodles, if were in a daring, exclamatory sort of mood.

Since we received the IntraLase laser two years ago, it has been nothing short of fantastic.It makes the process of creating the flap for LASIK much more comfortable. Its amazing to watch the mini bubbles forming in the cornea, each one so close to the next that a perfect flap is formed.

We made another exciting leap forward when we recently upgraded to the FS 60 model, which means an even faster and smoother flap formation. The FS 60 cuts the formation time by more than half, thus allowing us to make the flap in less than half a minute. This, in turn, allows us to make the laser spots even closer together, ultimately translating into an even smoother flap surface.<

All lasers treat major imperfections of the eye, such as nearsightedness, farsightedness and astigmatism. Yet there are other irregularities that we notice most in the dark. For example, when we drive at night, we notice that the headlights of oncoming cars are not distinct, small points of light, but are instead rather indistinct, appearing to flare and spread. What causes this phenomenon? Our pupils enlarge - or dilate - at night, and the edges of our lens and cornea contribute more to the images we see. These edges make lights appear to flare and spread.

These irregularities are also known as higher order aberrations. What makes the VisX laser and its component CustomVue laser system so remarkable is its ability to provide treatment which corrects these aberrations in addition to nearsightedness
