Said, your ophthalmologist will modify the curvature of your cornea to ensure proper light absorption by your retina. By using a laser, the process is carried out. Astigmatism, nearsightedness, and farsightedness are all conditions that doctors can treat with LASIK, a common eye procedure. You are not guaranteed 20/20 vision, and some activities may require wearing glasses or contact lenses.
How is LASIK performed?
Five phases make up the LASIK procedure:
- Your ophthalmologist will numb your eyes with eye drops once you’ve flattened out on the floor. Despite not experiencing any pain, the process could cause you to feel pressure. According to some patients, the pressure feels like a finger pressing against the eyelid.
- An eyelid holder and suction ring will be applied to your eye by your surgeon. You won’t blink because of the holder, and your eye won’t move because of the ring. Your vision may get blurry or perhaps go completely dark.
- Your surgeon will create a flap as thin as a piece of paper in your cornea using a laser programmed with your eye measurements. Then, as if flipping a book page, they will lift and fold back that flap.
- The next step will be for your surgeon to have you fixate on a light shining in your eye. Your eyes are fixed on it, not moving. Once more, the cornea is altered using the laser to improve light refraction. The laser could produce a clicking or ticking sound. The aroma of charred hair may be present.
- Your surgery will then fold the tissue flap back down. It will heal swiftly within two to three minutes and settle into place.
It’s okay if the LASIK procedure makes you feel uneasy. The idea of a laser entering their eye is unpleasant for everyone.
It may comfort you that LASIK is a safe surgery, with very few patients experiencing any long-term negative effects. You will discuss how LASIK surgery will be performed and what to anticipate with your ophthalmologist before the procedure with visualaidcenter . Remember that LASIK will give you a different vision. Driving and reading may still require the use of glasses or contacts. Your ophthalmologist will perform six tests before your procedure to ensure that you are a good candidate for LASIK surgery. They’ll probably:
- Please measure your pupils.
- The thickness and surface of your cornea.
- Analyse the type and volume of tears you produce (to check for dry eye).
- Ascertain the refractive error.
- Check to discover whether your vision has altered recently.
- Make sure your eyes are typically in good shape.
Before doing these tests, you will need to cease wearing contact lenses. Your ophthalmologist can measure your cornea more precisely if you do this. Depending on the kind of lenses you wear, it may take some time to transition from contact lenses to glasses:
- Four weeks for hard lenses.
- Two weeks for soft lenses.
- Three weeks for rigid gas permeable lenses or toric soft lenses.
- The day before your procedure, stop using the following products:
Finally, make sure someone from your family or close friends drives you home following the procedure. You will be able to drive later. Less than 30 minutes are needed for LASIK eye surgery. If you need a ride home, ensure a friend or relative is ready to assist.
What precautions must be taken after the surgery?
The incision site is maintained tidy, dry, and wrapped following surgery. The sutures must be kept sterile at all times, including at home, to prevent infection. Alcohol or peroxide is not required to clean the wound. Additionally, cleaning the surgery site or scraping away the scab is unnecessary. Simply washing the surgical site with water and soap will suffice most of the time. It is advisable to keep the incision site dry and not soak it in water.
- After surgery, it can be risky to drive. After surgery, a patient should never get behind the wheel. The patient’s reflexes may become sluggish due to the anaesthetic, painkillers, muscle relaxants, and other treatments.
- Avoid smoking. Smoking has an impact on the healing process. Smoking narrows the blood vessels, reducing the blood flow to the surgery site. Additionally, it harms inflammatory cells and lowers the amount of oxygen that reaches the area.
- Take infection warnings seriously. One should be able to determine whether the signs and symptoms they are experiencing are typical or need to be attended to by a doctor. Before releasing the patient, the doctor or nurse frequently reminded them of such indicators. However, it can become challenging to recall them. Remote post-surgical care programmes can serve as a medium for effective communication between patients and healthcare practitioners and a reminder for patients to follow these recommendations.
Patients should immediately contact a doctor if they encounter the following signs and symptoms.
- Having trouble breathing
- chest discomfort without cause
- unidentified fever
- nausea and diarrhoea
- Having trouble urinating
- Stitches produce pus and discharge that smells bad.
- Itching, tingling, and numbness at the site of the incision
- additional harmful effects that are particular to surgery
Eligibility criteria of LASIK Eye Surgery
To determine whether a patient is qualified to receive LASIK surgery, you should consider the following factors:
- Visual Stability: LASIK surgery may be carried out only once a patient has experienced steady eyesight for a significant amount of time. The vision would gradually deteriorate during a person’s adolescence if they had myopia.
- Hormonal changes: Hormonal shifts are the cause of unstable vision. Significant hormonal changes can be observed throughout pregnancy and breastfeeding. Women with these disorders should therefore wait until their vision stabilises before continuing.
- Age: Another crucial factor in determining LASIK surgery eligibility is age. Myopic patients experience regular visual alterations up until age 18. Thus, the patient must be at least 18 years old before choosing to have LASIK surgery.
Although the vast majority of LASIK surgery patients experience outstanding results, doctors should fully inform you of the risks, side effects, and potential LASIK complications before you decide to have the treatment. If you’re a good candidate for laser eye surgery, a skilled LASIK surgeon will let you know; if not, they’ll suggest that you could be a better candidate for another refractive procedure.
