How does LASIK Improve your Vision?

Wearing eyeglasses or contact lenses can be a distraction for some people, especially for those who are involved in sports or have an otherwise active lifestyle. LASIK surgery eliminates or greatly reduces the need for corrective lenses and is becoming more advanced as time goes on. The Wavefront LASIK method is the one most commonly used methods, however, treatment methods such as the Orbscan technology is also frequently used. LASIK treatments involve the creation of a flap in the patient’s cornea with a surgical instrument. A laser can also be used to fashion the flap and may even provide a better, more accurate result.

After the flap has been made, part of the cornea becomes exposed and is reshaped. This reshaping is done with an excimer laser which alters the way light is reflected onto the retina. It is by this reconfiguration of the cornea that the enables the patient to see better. After the reshaping has been completed, the flap is then replaced. LASIK is generally performed on an outpatient basis and is virtually painless. The procedure is also relatively quick, taking only about 30 minutes from start to finish. Prior to the procedure, the patient is given an ocular anesthetic, and should the patient become anxious, a pre-operative sedative can be administered to calm him.

After the pre-operative medications have been given, the patient is then asked to lie down on the operating table. A device will then hold the eyelid in place, preventing it from closing during the surgical procedure. This instrument also contains a suction device which helps maintain ocular pressure. The amount of tissue that is removed is typically determined by a computer which has been programmed with precise measurements that have been calculated during the assessment stage of the pre-operative appointment. Although the patient feels no pain during the LASIK procedure, he may hear a clicking noise coming from the laser. Furthermore, the patient may also notice a slight odor caused by the process of tissue removal. Although both eyes can be treated on the same day, many eye surgeons prefer to wait about a week in between procedures.

The term LASIK refers to laser-assisted in situ keratomileusis and is performed by an experienced ophthalmologist. Reshaping the cornea via LASIK surgery can correct such deficiencies such as astigmatism, myopia and hyperopia, also known as farsightedness. Although most people can benefit from the LASIK procedure, its benefits may be more pronounced in those with mild to moderate forms of myopia.

The recovery phase of the LASIK surgery is typically uneventful. Generally, the patient is able to resume his daily routine within 24 hours of the surgery. Many doctors, however, recommend that the patient rest for several days to facilitate healing. It is also important for the patient to understand his post-operative instructions. These include the avoidance of rubbing the affected eye and refraining from heavy lifting or strenuous exercise. Exercising and heavy lifting can increase eye pressure and cause ocular damage and visual disturbances. Patients are also instructed to watch for signs of infection, including drainage, fever, chills and increased redness. Patients may also notice hazy vision, dry eyes, halos around bright lights and an increase in glare. These symptoms generally occur soon after the procedure and gradually disappear over time.

Although complications are rare, they can occur. Complications are more common when an inexperienced eye surgeon performs the procedure and when pre-existing medical conditions are present. Diabetics are prone to a condition known as diabetic retinopathy, which may affect the outcome of the LASIK procedure. In addition, diabetes can cause problems with the vasculature of the eye, delaying the healing process. These complications are uncommon and can generally be treated effectively to avoid permanent visual deficits.

Though LASIK surgery is not a terribly invasive procedure, slight bleeding can occur. In fact, many eye surgeons will ask that the patient withhold certain medications such as aspirin or other blood thinners a week prior to surgery. These medications thin the blood and put the patient at a higher risk for bleeding. The patient should never stop taking his cardioprotective aspirin or other anticoagulant medication without first checking with his primary care doctor. Doing so without medical clearance may put the the patient at risk for cardiovascular events such as heart attack or stroke.

The LASIK procedure is considered very safe and effective. Because of its safety record and low level of complications, LASIK surgery is an effective option for virtually anyone who wants to improve their vision and get rid of their corrective lenses. It is important for the patient to note, however, that even though LASIK surgery will probably dramatically improve his vision, it may not perfect it. Although most patients will be able to stop wearing glasses after the procedure, some may still be required to wear corrective lenses, albeit at a much lower strength.
