For patients considering Houston LASIK eye surgery, understanding the techniques and strategies used to perform these procedures can offer added support during the lead-up to these surgeries. Here are some facts you should know about eye surgery and general vision correction before your upcoming LASIK procedure.
Essentials of Vision
The human eye consists of several different components that work together to make vision possible. Light passes through the pupil, the cornea and the lens on its way to the retina, which absorbs light and converts it into electrical energy that can be decoded by the brain to create visual images. If the lens or cornea are improperly shaped, the light reaching the retina can be distorted to reduce the ability of patients to see clearly. External vision correction solutions like eyeglasses and contacts refract light before it reaches the cornea and lens to compensate for defects in these parts of the eye.
The Cornea and the Lens
The cornea serves as a clear protective layer that provides some refraction for light entering the eye. This light then passes through the pupil to the interior of the eye and is refracted even further by the lens, allowing it to focus on the retina and create a clear image. Vision problems may be caused by irregularities or deformations of the cornea or the lens. In most cases, changing the shape of the cornea is the most effective way to correct these issues to improve eyesight and ensure clear visibility for patients.
How LASIK Works
Rather than changing the refraction of light before it enters the eye, LASIK procedures actually reshape the cornea to improve vision for patients. The surgery uses ultraviolet laser light to remove extremely thin layers of tissue from the cornea to change its refractive properties. These techniques can be used to correct nearsightedness, farsightedness and astigmatism without the need for glasses or contact lenses, making LASIK eye surgery a solid investment for patients with imperfect vision.
Preparing for the LASIK Procedure
Houston LASIK providers typically begin with a comprehensive eye examination that assesses the degree of vision correction needed and the overall health of your eyes. If you are susceptible to dry eyes, your surgeon may prescribe eye drops to correct this condition before and after your procedure. Precise measurements of all parts of the eye will also be taken to ensure the most accurate results during your surgery. If you currently wear contact lenses, your surgeon will ask you to stop wearing them prior to your initial consultation and during the interim period before your surgery.
What to Expect During LASIK
LASIK is typically performed on an outpatient basis, allowing you to enjoy faster recovery times and reduced discomfort after your Houston eye surgery procedure. You will be awake for the procedure and will usually be asked to look at a light while the laser reshapes your cornea to correct your vision. This process is generally painless; some patients do report slight pressure during the procedure. A series of clicks are also associated with the equipment used to perform LASIK.
After Your Surgery
Immediately after your LASIK procedure, you may experience blurred vision, itchiness or burning sensations in your eyes. These symptoms typically clear up by the day after your surgery. You will not be able to drive home on the day of your procedure and will need to see your surgeon for a vision test before being allowed back behind the wheel. Physicians generally recommend taking a couple of days off work to allow your eyes time to heal and recover. Avoiding high-impact aerobics and other demanding exercise routines can also protect your eyes from injury after your Houston LASIK surgery.
