LASIK and other forms of laser eye surgery, such as PRK and LASEK, have very high success rates and outstanding safety profiles. They can help you live without glasses or contacts by treating myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. However there may be some risks associated with LASIK surgery. Sight-threatening complications like significant vision loss from LASIK surgery are extremely rare, and many side effects and laser eye surgery complications can be resolved with additional surgery or medical treatment.
However, just like any other operation, there are dangers, side effects, and restrictions to be aware of before deciding to have the treatment done (or any type of procedure, for that matter). Choosing a professional and experienced LASIK eye surgeon will help you minimise these risks and get the greatest results from laser eye surgery.

The first step is to see if you’re a good candidate for laser vision correction. To establish your candidacy for LASIK surgery, your eye doctor will perform a thorough diagnostic eye exam. He or she will look at your cornea’s shape and thickness, your refractive errors and pupil size, the moistness of your eyes (to rule out dry eye syndrome), your overall health and medical history, and any drugs you’re taking.
Don’t worry if you’re not a suitable candidate for LASIK; other vision correction surgeries such as PRK, LASEK, or implanted lenses may be able to correct your vision.


The following are some of the most common risks associated with LASIK surgery. Medical treatment or extra “enhancement” surgery can usually fix most of these issues.

Temporary Vision Disturbance

It’s common and anticipated to have some discomfort in the days following LASIK surgery, such as moderate inflammation and light sensitivity. You may also notice halos, glare, and starbursts in low-light surroundings, especially at night; dry eye symptoms; cloudy vision; and diminished visual sharpness in the first few weeks or months. In the vast majority of cases, these issues are very transitory and will go away in three to six months.

Flap Complications

A tiny hinged flap is created on the front surface of the cornea during the LASIK surgery. This is elevated during surgery to allow for laser eye reshaping. After that, the flap is restored to create a natural bandage.
If the LASIK flap is not formed properly, it may not adhere adequately to the eye’s surface, or small creases known as striae (STRIE-ee) may form in the flap. Optical distortions and impaired vision might result from these flap problems.
Remember that choosing a trustworthy, qualified eye surgeon might lower your chance of LASIK issues.

Dry Eyes

Tear production is reduced in some patients who have LASIK surgery, which can cause eye pain and poor vision. LASIK patients account for nearly half of all cases of transient dry eye syndrome.
After LASIK surgery, dry eye syndrome is usually only temporary and can be efficiently addressed with lubricating eye drops or other methods.
Dry eye symptoms normally go away when the eye heals completely, which can take up to six months. LASIK candidates who already have significant dry eyes are frequently ruled out.

Under Correction or Over Correction 

After LASIK eye surgery, not everyone will attain 20/20 vision, and contact lenses or eyeglasses may be required for some or all activities in rare circumstances. Your visual outcome will be less than ideal if the laser eliminates too much or too little corneal tissue, or if your eye’s healing response is not usual.
Your eyes did not respond to laser eye surgery in an expected fashion, which could be one reason for a less-than-ideal result. Another possibility is that your vision was perfect just after LASIK but deteriorated over time owing to “over-healing.”
After your surgeon confirms that your residual refractive error is stable, a considerable undercorrection or regression can usually be successfully addressed with additional laser vision correction.

Eye Infection 

Infections are uncommon after LASIK surgery. Eye infections are less common following LASIK than after flap-free corneal refractive surgeries like PRK because the corneal flap acts as a natural bandage. Even so, it’s critical to follow the instructions for using medicated eye drops following your LASIK treatment to avoid infection and reduce inflammation as your eyes heal.
Millions of people have benefited from laser eye surgery, which has a high patient satisfaction rate. LASIK, like any operation, has the possibility for problems. Before deciding to proceed with surgery, it is critical that you balance the benefits and risks associated with LASIK surgery and choose a qualified eye surgeon for the least complications.
