Lasik surgery is a life-changing process. There are associated pros and cons like any other surgeries. It is important to evaluate the pros and cons at every step of the procedure.
Lasik surgery is the most common medical procedure for eye treatments. The procedure is safe in most cases. However, the associated risks increase with various factors. For this reason, patients must meet an eligibility requirement to receive the surgery. Most of the pros and cons of Lasik focus on vision.
People over the age of 40 are generally ineligible for the procedure. The cornea hardens over time and this makes it more difficult to reshape it. It is best to speak with a doctor to learn more about eligibility.
Pro: Better Visual Acuity
Patients have nearly an 80 percent chance to regain perfect vision through Lasik surgery. In almost every case, vision is significantly improved. The results last a lifetime.
Lasik surgery is known to be a quick and safe procedure. A surgeon uses a tool called a microkeratome to form a cover over the cornea. While the cover is placed on the cornea, the surgeon pulls back underlying tissue. This tissue is known as the stroma.
A powerful laser is directed at the cornea. This begins the reshaping process. Once the cornea is rehappened, light can pass through the eye more effectively.
Con: Rare Night Vision Issues
The epithelial flap that is created from the surgery can compromise some aspects of visions. Alterations to night vision is a common side-effect.
The human eye contains many rods and cones that are responsible for perceived vision. Rods are more concentrated in the retina compared to cones. There are approximately 120 million rods in the retina.
These rods play a major role in night vision. The rods, optic nerve, and other components of the eye process the minimal light that is available in a dark setting. This helps to form a cohesive image. The eye is a natural filter and can detect the edges of objects in the dark.
This ability is slightly compromised after the surgery. The eye must change shape to accommodate the new cornea and this may affect the surrounding rods.
Patients may become more sensitive to light sources in the dark. This can create halos and other after-images. If this is the case, it is best to limit some night-time activities.
Night vision issues are not permanent. The amount of time it takes to heal depends on the surgery. The issue usually subsides within a few months.
The Pros and Cons of Lasik: How Does Lasik Surgery Change Overall Appearance?
Lasik surgery usually does not change the color or shape of the eye. In some rare cases, a strong laser can remove some pigmentation from the eye. This may cause the eye to turn slightly blue or gray.
Generally, an eye mask musk is worn after the surgery because the eyes are too sensitive. It is best to travel with someone. The mask must be worn for 24 hours.
The eyes may appear red due to irritation. If a blood vessel ruptures, then a part of the eye may seem completely red. This does not happen often. A broken blood vessel is not a cause for concern if no pain is present. The time for the eye to heal completely is one or two days.
Pro: No Need for Glasses
For patients under the age of 40, glasses are no longer needed after the surgery. However, there are other factors that may require a patient to keep their glasses after surgery.
Patients with eye conditions like glaucoma may not experience full restoration because glaucoma is a progressive condition. Lasik surgery can mitigate the symptoms, but it cannot completely eliminate the condition.
Glasses should not be worn if the surgery completely restores vision. This can put further strain on the eyes and lead to a relapse.
Con: Subconjunctival Hemorrhage
A subconjunctival hemorrhage occurs when a blood vessel in the eye breaks. This causes blood to leak near the surface of the eye. The sclera or white part of the eye may appear partially or completely red. Pros and cons of Lasik surgery are experienced differently between patients.
Despite the appearance, this type of hemorrhage is benign. A broken blood vessel in the eye can occur for several reasons including headaches, eye strain, or an injury to the eye. Heavy lifting, sneezing, or constipation may also lead to a subconjunctival hemorrhage.
Eye drops can help to reduce redness. The affected eye should be left alone. Areas that contain large amounts of a certain allergen should be avoided.
The Pros and Cons of Lasik: How Do the Eyes Feel After the Surgery?
Other pros and cons of Lasik include recovery. There is some discomfort after the surgery. The eye may burn or develop an itch. Patients should not touch the eye for at least 24 hours after the surgery. Touching the eye can displace the flap and cause damage to the eye.
Vision is blurry immediately after surgery. It is important to hydrate during this period. This helps the eye to recover. Sports and other physically demanding activities should be avoided for the first three days.
Pro: Irritating Contact Lenses Are Gone
There is no longer a need to spend two minutes every morning to put on contacts. In fact, contacts should not be worn anymore because this can change the shape of the eye. However, these are not all the pros and cons of Lasik.
After the surgery, the eye can filter light more efficiently during both the day and night time. Environments become crisper and more defined.
Lasik surgery can prove to be a cost-effective alternative to contacts. In most cases, it is a one-time procedure. Contacts no longer need to be replaced. This can save thousands of dollars in the long run.
Con: Temporary Dry Eyes
It takes several months for vision to stabilize. The eyes may dry up faster during this period. It is important to keep the eyes lubricated with eye drops. If the eyes are too dry, then the chances of a subconjunctival hemorrhage greatly increase. A humidifier can help to alleviate dry eyes.
Lotions and skin creams should be used with caution. Many of these products contain chemicals that can irritate the skin. Some of these chemicals are small enough to sink through the pores. The skin surrounding the eyes is especially thin. These are a few more pros and cons of Lasik.
Contacts lenses, make-up, and lotions should be avoided at least one week prior to surgery. Application of these products can increase the risk of infection can increase the post-recovery time. Patients may even become ineligible for treatment if the products are applied within a week of the scheduled surgery.
The Pros and Cons of Lasik: Is Lasik Surgery the Right Option?
Lasik surgery is a cost-effective and safe procedure to improve vision. If needed, the surgery can be performed several times. Lasik surgery may not be right for everyone. An eye doctor can use a series of assessment to determine eligibility.
It is better to receive Lasik surgery at a young age because the body is more adaptive. This can make the surgery much easier.
While there are some minor risks associated with Lasik surgery, the pros far outweigh the cons. Some pros and cons of Lasik are minor. This depends on the need for Lasik surgery.
