Can Smoking Affect Your Laser Eye Surgery Results?

Are you considering laser eye surgery in Toronto to achieve clear vision without the need for glasses or contact lenses? If you smoke, you might wonder how smoking could affect the results of your procedure.

This article delves into the potential impacts of smoking on laser eye surgery outcomes, providing a detailed examination of the potential risks and complications.

What is laser eye surgery?

Laser eye surgery, such as LASIK (laser-assisted in situ keratomileusis), is a widely used procedure to improve visual acuity. The surgery involves reshaping the cornea to ensure light entering the eye is correctly focused onto the retina, thereby improving vision clarity.

The procedure is primarily conducted to address the following vision issues:

• Astigmatism: An irregularly shaped cornea or lens prevents light from focusing properly on the retina, resulting in distorted or blurred vision at all distances.
• Farsightedness (hyperopia): Here, the eyeball is too short or the cornea too flat, causing light to focus behind the retina, which makes near objects blurry.
• Nearsightedness (myopia): This condition occurs when the eyeball is too long, or the cornea is too curved. It causes light to focus in front of the retina and makes distant objects appear blurry.

The Risks of Smoking After Laser Eye Surgery

Smoking is universally recognized as harmful, contributing to diseases such as cancer, lung disease, and heart disease. Beyond these well-known risks, smoking can negatively affect the healing process after LASIK surgery.

By understanding these dangers, patients can make informed decisions and take proactive steps toward a successful LASIK experience. Here are the post-LASIK complications that can arise from smoking.

Higher Risk of Infection

The most significant risk associated with smoking after LASIK surgery is infection. While modern LASIK techniques have minimized physical contact with the eye, thereby reducing infection risks, smoking hampers proper wound healing.

This impaired healing can elevate the risk of corneal infections, especially in the corneal flap created during the procedure. Such infections can lead to severe discomfort and compromised vision quality in the long term.

Increased Risk of Dry Eyes

Smoking is associated with dry eye syndrome, a condition that can be exacerbated by laser eye surgery. Adequate tear production and lubrication are essential for healing, and smokers may struggle with prolonged dryness and discomfort.

Therefore, avoiding smoke exposure, both first-hand and second-hand, is critical during the recovery phase to mitigate these symptoms.

Heightened Irritation and Sensitivity

Post-LASIK, patients often experience temporary irritation, characterized by red, itchy eyes. Smoking exacerbates this irritation, introducing additional discomfort and prolonging the recovery period.

The chemicals in cigarette smoke can further irritate the eyes, making them more sensitive and prone to redness and itchiness. For optimal healing, patients are advised to steer clear of smoking and environments where they might be exposed to second-hand smoke.

Delayed Healing Process

Smoking decreases the oxygen-carrying capacity of the blood due to the presence of carbon monoxide. Adequate oxygen levels are crucial for the healing of corneal tissues after LASIK. Reduced oxygen supply can slow the healing process, leading to prolonged recovery and potentially less optimal visual outcomes.

The Prolonged Impact of Smoking on Ocular Health

Smoking can lead to conditions such as retinal vascular occlusions. While these conditions primarily affect the retina, poor vascular health can indirectly impact the success and longevity of LASIK surgery results. Healthy blood vessels are crucial for maintaining good vision post-surgery.

Moreover, smokers are at a higher risk of developing cataracts, which can undermine the benefits of laser eye surgery. Although laser eye surgery corrects refractive errors, the development of cataracts can later diminish vision quality.

Preparing for Surgery: The Significance of Smoking Cessation

Given the risks mentioned above, quitting smoking well before undergoing laser eye surgery in Toronto is crucial. In some cases, the negative impact of smoking on vision and general health may render individuals unsuitable candidates for LASIK.

Healthcare providers strongly recommend cessation programs to help patients quit smoking, thereby improving their surgical outcomes and overall health. New evidence indicates that smokers who quit at least four weeks before surgery have fewer complications and better results six months post-operation.

A joint study by WHO, the University of Newcastle, and WFSA (World Federation of Societies of Anaesthesiologists) found that each additional tobacco-free week beyond four weeks improves health outcomes by 19%. This improvement is attributed to enhanced blood flow throughout the body to essential organs, facilitating better healing and recovery.

Post-Surgery: Maintaining a Smoke-Free Period

Surgeons typically recommend that patients refrain from smoking for several weeks following LASIK. This recommendation is grounded in protecting the delicate healing process and ensuring optimal vision outcomes.

A smoke-free period post-surgery significantly reduces the risk of complications and supports the restoration of clear vision.

Consider Quitting Permanently

LASIK surgery can serve as a motivating factor to quit smoking permanently. By eliminating smoking from their lifestyle, individuals improve their chances of a successful LASIK outcome and enhance their overall health and well-being.

For those who need assistance in quitting, numerous resources are available, including counselling, support groups, and nicotine replacement therapies.

Practical Tips for a Healthy Recovery

In addition to quitting smoking, there are several other steps patients can take to support their recovery and achieve the best possible results from laser eye surgery:

• Avoid water contact with eyes: Patients should take baths instead of showers during the initial recovery period to avoid getting water in their eyes.
• Use artificial tears: To alleviate dry eye symptoms, patients should use artificial tears as their eye surgeon recommends.
• Wear UV-protective sunglasses: Protecting the eyes from harmful UV rays is essential, particularly after laser eye surgery. Sunglasses with complete UV protection can help shield the eyes and promote healing.
• Refrain from using eye cosmetics: It is advisable to avoid applying lotions, creams, or cosmetics to the eye area for at least the first week of post-surgery.
