What is LASIK?
One of the most popular ways to correct vision is with LASIK (laser in-situ keratomileusis), which uses a laser to change the curvature of the cornea (outer window of the eye). What is Lasik? This kind of eye surgery removes tissue within the cornea to treat low to high levels of nearsightedness, farsightedness and astigmatism.
The cornea is a part of the eye that helps focus light to create an image on the retina. It works similar to the lens of a camera which focuses light to create an image on film. The bending and focusing of light is also known as refraction. Usually the shape of the cornea and the eye are not perfect and the image on the retina is out-of-focus (blurred) or distorted.
These imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: myopia, hyperopia and astigmatism.
Persons with myopia, or nearsightedness, have more difficulty seeing distant objects as clearly as near objects. LASIK treats nearsightedness by flattening the shape of the cornea, through very minuscule tissue removal (typically less than the thickness of a human hair) from the center of the cornea.
Persons with hyperopia, or farsightedness, have more difficulty seeing near objects as clearly as distant objects. To treat farsightedness, the flat cornea is made steeper by removing tissue outside of the central optical zone of the cornea. This moves the point of focus from behind the retina to directly on the retina.
Astigmatism is a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye. Combinations of myopia and astigmatism or hyperopia and astigmatism are common. To treat astigmatism, the cornea is made more spherical—like a basketball instead of a football. This eliminates multiple focusing points within the eye and creates one point of focus on the retina.
LASIK has quickly become the procedure of choice for most patients because they recover quickly and have fewer side effects and complications than with other methods of vision correction. Most LASIK patients notice a significant improvement in their vision soon after surgery.
The Right Decision: Accurate Preoperative Evaluation of LASIK Candidates
What is Lasik preoperative evaluation? Determining your LASIK candidacy is the crucial next step on your journey for better vision. Dr. Jackson will evaluate your vision thoroughly through a preoperative advanced diagnostic exam to determine if you are a candidate for LASIK.
On the day of your preoperative exam, we will complete multiple tests and points of evaluation including:
- Corneal thickness testing
- Pupil size measurement
- Dry eye evaluation
- Tests to analyze the shape of your cornea
- Measure the level of nearsightedness, farsightedness, or astigmatism
- Wavefront measurements
- Complete dilated eye exam to review retina
Once the information is gathered, he will help you decide which procedure is best for you based not only on your vision impairment, but also your overall health, age and lifestyle. If you are not a candidate, Dr. Jackson provides many refractive procedures that apply to your specific visual problem.
LASIK with Jacksoneye
Many people love the option of getting rid of their eyeglasses or contacts; however they cringe at the thought of having surgery performed on their eyes. We’re hoping that we can help you overcome any fear by providing helpful information about Lasik. With time tested technology and fine-tuned surgical skill, this procedure is one of the safest, most effective eye treatments available. We believe the benefits of LASIK far outweigh the risks.
The LASIK eye surgery procedure is based on the premise that imperfections in vision are caused by the misshaped cornea. Therefore the more perfectly shaped the cornea, the better one’s vision will be. LASIK surgery provides, with little or no discomfort, the ability to reshape the cornea and correct the following imperfections.
- Nearsightedness (myopia)
- Farsightedness (hyperopia)
- Astigmatism (blurry vision)
What is LASIK as a procedure? It’s an eye surgery that is performed as an outpatient procedure in the comfort and convenience of our laser surgical suite that is close to Chicago, Gurnee, Antioch, Libertyville and other places within North Chicago area. The entire vision correction procedure takes less than 15 minutes and both eyes are done in the same sitting. The procedure is performed using topical eye drop anesthesia. Our patients see a dramatic improvement in their vision within the first day. Most patients return to their normal activities within a day or two.
