If you have been considering having laser eye surgery, you may be wondering if it will correct all of your vision problems. The short answer is yes. Lasik eye surgery is a type of refractive surgery that works by reshaping the cornea (the clear layer at the front of the eye) to improve your vision.There are different types of Lasik eye surgery, but they have similar results. The most common type of Lasik eye surgery is called LASIK with IntraCorneal Ring Segment (ICRS). There are two main variations of this procedure: LASIK with ICRS/Photorefractive Keratectomy (PRK) and the LASIK with ICRS/Transepithelial PRK (Trans PRK). Both remove a ring of tissue from the cornea, but the way this is done is different.Trans PRK: With this procedure, the surgeon removes the ring of tissue from the cornea but leaves the epithelium (the outer layer of the cornea) intact. This is different from the standard LASIK procedure where the epithelium is removed.Trans PRK is performed with either a small ultraviolet (UV) light source or sterile water. The UV light source is used if there are no signs of an infection. You will be given antibiotics prophylactically to reduce the risk of infection.With either technique, once the ring segment has been removed, the surgeon will treat the cornea with a special antibiotic. At the same time, the surgeon will remove the corneal flap that covers the treated portion of the eye. Once the flap is removed, the surgeon will use special tools to put a soft bandage over the cornea and then suture the flap back in place.
How does Lasik work?
Most people who wear corrective lenses or have had refractive surgery know how difficult it can be to see in different conditions. For example, imagine if you had 20/20 vision in daylight but could only see 20 feet in the dark. That would be a problem for someone who needed to drive at night or work in a dark room. The cornea is responsible for focusing light entering the eye into the eye’s visual center. The cornea is a thin layer of tissue that sits at the front of the eye. The cornea contains no blood vessels and is therefore very sensitive to injury and infections.Since the cornea is not equipped with blood vessels, it is very difficult to heal after an injury or infection. This means that the cornea can take several weeks to fully recover from an injury or infection. This can be problematic for people who need their vision corrected and want to see clearly without wearing glasses or contact lenses.
What is the vision improvement after Lasik?
Most patients experience a significant improvement in their vision after Lasik. The degree of improvement is different for each patient, but it is often significant enough to eliminate the need for reading glasses. Depending on your specific needs, you may experience a 20/20 vision, 20/15 vision, 20/10 vision, or even better than 20/16 vision. The degree of improvement will depend on the amount of myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism in your eyes.
Is Lasik surgery right for me?
Lasik eye surgery is a very common procedure, but it is not for everyone. The only way to know if it is right for you is to meet with an eye doctor and discuss your options. There are different types of Lasik eye surgery and each one has different requirements. The best way to find out if Lasik surgery is right for you is to discuss your individual situation and needs with an eye doctor.There are several factors that must be considered before you decide to have Lasik eye surgery. These include your age, eye prescription, overall health, insurance coverage and the risks associated with the surgery.
The disadvantages of Lasik surgery
Every surgery has its risks. Some of the most common risks of Lasik eye surgery include: Corneal Scarring: This can occur if the cornea is not fully removed during the surgery. Corneal scarring can prevent you from having a normal and healthy eye in the future. Dilation Pupil: As you age, your eye’s pupil becomes more difficult to fully dilate. If the dilation of your pupil is not fully corrected after the surgery the light entering your eye will be uneven. Double Vision: This is a very common side effect of Lasik eye surgery. It usually occurs when the surgeon has not fully corrected your vision. It is usually temporary and will go away once your eye has fully healed. Loss of Vision: Some people experience a loss in vision after Lasik eye surgery. This side effect is uncommon and is usually temporary.
Bottom line
LASIK eye surgery is a common procedure that can significantly improve your vision. It is a safe and effective way to correct refractive errors such as myopia, hyperopia and astigmatism. The only downside is that it is a surgery that requires some recovery time.
