Lasik Surgery for vision correction has been around for a long time, and millions of people have taken advantage of this procedure so they could quit wearing eyeglasses or contact lenses. Not everyone was completely satisfied with the results, however, finding that their corrected vision wasn't as clear as they had hoped. They might still have needed to wear glasses for driving, for example, even though their vision had improved a great deal. A more recent technology known as iLasik Surgery has been developed to create more precise and customized results.

This technology works by generating a three-dimensional map of each eye that shows even the tiniest variations from the norm. That map allows the eye surgeon to achieve the most effective results when using a laser to make changes. It is useful for people with nearsightedness, farsightedness and astigmatism.

The ophthalmologist can correct the vision in each eye very quickly when using iLasik technology. Before this form of Lasik Surgery, a topical anesthetic is applied to each eye so there is no pain. Afterward, there may be some moderate discomfort, and a feeling of grittiness and dry eye sensations may linger as the eyes recover from surgery. There may be some sensitivity to light during the initial recovery time.

After laser surgery, the patient should rest the eyes and not try to read, use the computer or watch TV. Protective shields are supplied by the eye doctor so there's no accidental touching of the eyes. These should be worn while sleeping too, since the patient may instinctively try to rub the eyes.

Ophthalmologists generally recommend not driving until the first followup appointment, which takes place within a day or two of the operation. The eye doctor wants to make sure everything is progressing normally. Patients usually are told during this appointment that they can drive safely now.

The full visual correction may not be realized for a few months, as the process is gradual. There may be some episodes of blurriness, or times when the vision is better and then becomes less clear. It's important for patients not to become frustrated during this time and to realize they may need to continue wearing glasses for a while.

Clinical studies show that the results of this newer version of Lasik Eye Surgery are very successful. In fact, 94 percent of patients regain their 20/20 vision with iLasik surgery, and some of those find their vision is even better than 20/20.
