The Benefits of Laser-assisted In-situ Keratomileusis
Laser in-situ keratomileusis (LASIK), is a refractive surgical procedure where a patients nearsighted, or somewhat farsighted needs can be corrected with surgery, leaving the patient able to see as well, or nearly as well as they could with eyeglasses or contact lenses. The procedure is a fairly uncomplicated one with many benefits, yet the decision for a doctor to recommend it as a viable option for the patient can be a tough one.
Lasik is a procedure where a circular flap is cut into the corneal epithelium and Bowman’s Layer, revealing corneal stroma with a microkeratome, or a femtosecond laser. An Excimer laser is used to cut away parts of the stroma, using an ultra-violet light beam to reshape the cornea, thus correcting the patient’s refractive condition. A nearsighted patient’s cornea will be made flatter, while a farsighted patient’s cornea will be cut steeper. An astigmatic cornea can be reshaped to be more regular as well. The corneal flap is the replaced, allowing the corneas natural ability to heal quickly to contribute to most of the healing process. After the surgery is completed, the patient may go home and will see their regular eye doctor for the follow up care. Recovery time is usually one day up to a week.
Patients may elect to have lasik done to permit them to see without the aid of eyeglasses or contact lenses. Certain careers, such as modeling, and news broadcasting, are ones where a person may feel uncomfortable wearing glasses, and may not always have the time to insert or remove contacts.
Lasik surgery has its advantages including, less recovery time, less pain, and is rather quick, at about ten to twenty minutes per eye. Enabling a patient who has needed to wear glasses or contacts for a long time, to see clearly without needing correction can truly be a blessing.
Lasik can have complications such as, increased dryness, infection, increased sensitivity to bright...
