LASIK stands for “Laser-Assisted In-situ Keratomileusis,” referring to a refractive eye surgery that helps reshape the cornea and refocus the entering light. This procedure helps to refocus the light entering the cornea better onto the retina for a clearer vision. The LASIK procedure’s standard conditions requiring eye surgery include myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism.
When undergoing eye surgery with the LASIK process, the overall time is usually less than 20 minutes for the two eyes. And the result can be a fascinating use of both eyes for improved vision with the need for glasses or contact lenses. Meanwhile, the patient can begin to enjoy the benefits almost immediately and more so when the eyes fully heal. Whereas, if LASIK is not suitable for anyone, one can consider the PRK or LASEK eye surgery for correction.
This article addresses some of the required steps before, during, and after LASIK eye surgery.
Before undergoing LASIK eye surgery
The doctor will have to examine the eyes thoroughly to establish that the condition of the eyes is perfect for the procedure. Note at this point that some patients who have other underlying conditions with their eyes may not be able to undergo LASIK. In addition, if a patient is over 40 years old, LASIK may not be advisable, but other similar procedures may work better.
Other parts of the eyes that require examination also include the thickness and shape of your cornea, the pupil size, and the refractive errors to correct in the eyes. In addition, the doctor may also have to examine the condition of the eye film that covers the eye surface. This procedure ensures that you will not develop any form of dry eyes after undergoing LASIK.
The cross-examination of the eyes is easier when using the corneal topographer. This tool measures the curvature of the eye’s front surface. Meanwhile, it can also create a sort of map for the cornea. The LASIK procedure also involves wavelength technology, including a wavefront analysis, sending light waves through the eyes. The result is a more precise and accurate corneal map. You can read about Lasik eye surgery costs in Sydney by clicking here.
Furthermore, the optician and surgeon may also study the general history of your eyes and note any medication you are on before starting the procedure. In addition, the LASIK process may require you to stay off glasses or lenses for a period just before the LASIK procedure. A simple reason for this procedure is that it can help prevent the natural wear and tear of the contact lens.
What happens during eye surgery using LASIK?
Before you are wheeled in for LASIK eye surgery, you will be given some numbing eye drops to prevent any discomfort. In addition, the doctor may prescribe some medications that can help you relax during the eye surgery. At the same time, you must be in the correct position under the laser and the lid speculum, which allows keeping your eyes open.
The next step is for the eye surgeon to mark out the cornea with an ink marker and create a flap. In addition, the doctor may also use a suction ring to the front of the eyes to prevent any eye movement. The process can also prevent loss of eye contact that could lead to affected flap quality. The surgeon can then use the computer to adjust the excimer laser to fit your peculiar needs for the surgery.
Similarly, the patient may have to look at a target light for a short time while the doctor examines the eye through a microscope. When the procedure starts and the surgeon uses laser light sources to reshape the cornea. While the process is going on, you may feel pressure on the eyes or a clicking sound during the surgery.
What happens after LASIK surgery?
Immediately after an eye surgery involving the LASIK procedure, you may feel some itchy or burning sensation on the eyes. That feeling is only temporal and may not necessarily become an issue in the long run. The surgeon also takes some time to rest before doing a post-operative examination of the eyes. You can now get …
