Understanding how LASIK Eye Surgery Works
The more you understand what LASIK eye surgery takes, the more you can relax and undergo the procedure without fear. LASIK eye surgery is one typical way to correct eye defects using laser technology. It involves reshaping the cornea of the eyes to fix the refractive errors that may be responsible for impaired vision. Also, it is effective in remedying shortsightedness, farsightedness, and astigmatism.
Technological advancement has established that it can cure eye defects related to refraction errors. For some people, the decision is in between whether to undergo the procedure or not. Moreover, you can book a consultation time with us for a pre-surgery examination or schedule time for the actual surgery. Below is a detailed explanation of how lasik eye surgery works and what potential patients can learn from that experience.
How does LASIK Eye Surgery Work?
The primary culprit of eye defects in people is the refractive error of light that falls on the cornea of the eyes. Therefore, when the vision gets blurry, it results from poor refraction. When you attempt to look at an object, the light rays pass through the various external parts of the eye. Examples include the cornea, the transparent dome-shaped structure covering the front of the eye, and the crystalline lens.
The lens is that structure that receives the light rays and refracts them to the cornea. The cornea refocuses the light to form an image on the retina at the back of the eye. Any error in image formation means that the image will be pretty different from the actual size and sharpness. It may show as a blurry image in a compromised vision.
To correct it, people often resolve to use eyeglasses or contact lenses. But these two options only bring about a temporary fix and do not give a permanent solution to the problem. The quick options help refocus the image’s light on the right spot on the retina to produce the best possible, sharp, and clear vision. To resolve the problem permanently, LASIK eye surgery can provide a better and more effective solution that will correct the refractive error.
This time, the surgery involves using laser technology to reshape the cornea to correct the refraction. LASIK stands for the Laser-in-situ Keratomileusis, which uses laser technology for the procedure.
Step-by-step procedure of the LASIK eye surgery
The surgeon uses an instrument known as the microkeratome to create a flap on the cornea. He then pulls that back to expose the underlying corneal tissue. Also, there are optional LASIK forms that the surgeon can employ with a high-energy laser to help create such a flap. On the other hand, the surgeon can use an excimer to reshape a portion of the cornea and correct the patient’s vision that was impaired by refractive errors.
You may wonder how the surgeon can know the right shape to correct what you have. It also uses this technology to reconfigure the cornea in a way that can fix the refractive error and achieve the right image. Before the surgery, the doctor may need to create a pre-specified pattern of the cornea. It may require advanced diagnostic technology with extensive pre-operative tests to determine the best method.
The test can also measure the shape and thickness of the cornea of the eyes. As a result, the professionals will create a three-dimensional map of the structure of the cornea. Putting all the results together, the surgeon can determine what shape of the cornea he is dealing with before the actual procedure and the best method of correcting the vision impairments.
What can you expect before, during, and after the LASIK Surgery?
LASIK, the easiest and fastest eye corrective procedure, is also a speedy recovery period. It becomes an advantage when you compare it to other medical practices. Moreover, most people can quickly return to regular routines and get back to their lives after the procedure. Also, LASIK eye surgery takes a process but remains very influential in results. Below is a short description of the surgery process, from preparation to full recovery.
- Before the Surgery
It is essential to attend a pre-operative consultation before your surgery session. This session will allow you to determine the eligibility for the LASIK procedure or if the patient will consider another option. The pre-operative procedure is often free and free of any obligation where the individuals can determine its suitability for their condition.
While undergoing the pre-operative examination, the medical professional examines your eyes. In addition, the surgeon asks specific questions and asks you to describe how you feel. In addition, he explains the entire procedure ahead of you to you. Moreover, he notes all your questions and answers that prepare you ahead of what is expected.
- During the LASIK Surgery
You should also know what to do on the day of your surgery. Just before the session begins, the professionals once again evaluate your eyes to verify the condition of the parts. In addition to the previous results, they also consider your chances and approve your viability for LASIK eye surgery.
A surgical counselor will also meet with you to ask some final questions and points. He also explains the procedure’s expectations and how you may likely feel. Other steps involve reviewing all the post-operative care instructions and filling out any remaining paperwork. Just before the process starts, you will also be asked if you took to all instructions given to you earlier. The entire surgery only lasts for 15 minutes.
- After the Surgery
Immediately after your procedure, you may feel eye irritation, including an itchy, burning, or teary sensation. Also, you may have blurry vision, but the surgery is an entirely painless procedure. A good clinic will allow you to wait for some time to calm down and let your cornea and flap heal together. In addition, you may be given a pair of sunglasses as protection from the sensitivity of light. You also learn care instructions to help your eyes recover more quickly and efficiently.
