Does LASIK Eye Surgery Hurt?

Laser eye surgery has revolutionized the field of ophthalmology, offering millions of people a way to achieve clearer vision without the need for glasses or contact lenses. Whether you’re nearsighted, farsighted, or have astigmatism, laser eye surgery could be the solution to improve your vision and simplify your daily life. Here’s everything you need to know about laser eye surgery, including how it works, the types available, and what to expect from the procedure.


What is Laser Eye Surgery?

Laser eye surgery is a popular medical procedure used to correct common vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. By reshaping the cornea—the clear, dome-shaped surface of the eye—laser surgery helps focus light more effectively on the retina, resulting in clearer vision. The procedure is quick, minimally invasive, and has a high success rate.

There are several types of laser eye surgery, but the most common and well-known are LASIK (Laser-Assisted in Situ Keratomileusis), PRK (Photorefractive Keratectomy), and SMILE (Small Incision Lenticule Extraction).


How Does Laser Eye Surgery Work?

During laser eye surgery, a highly focused laser is used to make precise adjustments to the cornea, altering its shape to improve the way light enters the eye. This process works differently for different vision problems:

  • Nearsightedness (Myopia): The cornea is too steep, causing light to focus in front of the retina. The laser flattens the cornea to correct this.
  • Farsightedness (Hyperopia): The cornea is too flat, causing light to focus behind the retina. The laser reshapes the cornea to make it steeper.
  • Astigmatism: The cornea has an irregular shape, causing blurred vision. The laser smooths the cornea to make it more symmetrical.

While the procedure itself takes only minutes per eye, the preparation and recovery time can vary based on the individual and the type of surgery performed.


Types of Laser Eye Surgery

1. LASIK (Laser-Assisted in Situ Keratomileusis)

LASIK is by far the most popular and widely used laser eye surgery. It involves creating a thin flap on the surface of the cornea, which is lifted to expose the tissue underneath. The laser then reshapes the cornea to correct refractive errors. Once the laser treatment is complete, the flap is replaced, and the eye begins healing on its own.

  • Pros: Quick recovery time, minimal discomfort, and usually no need for stitches.
  • Cons: Some people may experience temporary dryness or glare, and it’s not suitable for people with certain corneal conditions or very high prescriptions.

2. PRK (Photorefractive Keratectomy)

PRK is an alternative to LASIK and is ideal for patients with thinner corneas or those who have certain lifestyle factors, such as high levels of physical activity. In PRK, the outer layer of the cornea (epithelium) is removed to allow the laser to reshape the underlying tissue. After the procedure, the epithelium regenerates naturally.

  • Pros: No flap is created, which can be beneficial for those with thin corneas or high-risk lifestyles (such as athletes).
  • Cons: A longer recovery period compared to LASIK, with more discomfort in the days following surgery.

3. SMILE (Small Incision Lenticule Extraction)

SMILE is a newer, minimally invasive laser procedure that uses a femtosecond laser to create a small lenticule (a lens-shaped piece of tissue) within the cornea. The lenticule is then removed through a small incision. This process is considered less disruptive to the eye’s surface than LASIK and PRK.

  • Pros: Less risk of dry eye symptoms, no need for a flap, and faster recovery compared to PRK.
  • Cons: Available for myopia treatment only, and may not be as widely available as LASIK.

Who is a Good Candidate for Laser Eye Surgery?

Laser eye surgery is a highly effective treatment for most people, but not everyone is a candidate. Good candidates typically:

  • Are 18 years or older (eyes must have stopped changing in prescription)
  • Have a stable prescription for at least a year
  • Have healthy eyes without significant corneal disease, cataracts, or glaucoma
  • Do not have uncontrolled health issues (like diabetes) that could affect healing

It’s important to undergo a thorough eye examination with an ophthalmologist or optometrist to determine if laser eye surgery is right for you.


What to Expect During the Procedure

Laser eye surgery is typically performed on an outpatient basis, meaning you’ll be able to go home the same day. The process usually follows these steps:

  1. Preparation: Numbing eye drops are applied to ensure that you don’t feel pain during the procedure. A special instrument may be used to keep your eyelids open.
  2. The Laser Treatment: Depending on the type of surgery, the doctor will either create a flap in the cornea or remove the outer layer of tissue. The laser then reshapes the cornea.
  3. Post-Procedure: After the surgery, you may experience some mild discomfort or a sensation of grittiness in your eyes. Your doctor may prescribe eye drops to help with healing and prevent infection.

The procedure itself usually takes about 10-15 minutes per eye, and you’ll be able to see the results immediately, though full visual recovery may take several days to a few weeks.


Recovery and Aftercare

While recovery times can vary based on the procedure and individual, most people experience relatively quick healing:

  • LASIK: Most people can return to normal activities within 1-2 days, though complete healing may take a few weeks.
  • PRK: Full recovery may take 1-2 weeks, and you may need to avoid certain activities during this time.
  • SMILE: Recovery time is typically faster than PRK, with many patients seeing improvement in just a few days.

It’s important to follow your doctor’s aftercare instructions closely. This may include:

  • Using prescribed eye drops to promote healing and prevent infection
  • Avoiding rubbing your eyes or getting water in them during the initial healing period
  • Wearing sunglasses to protect your eyes from sunlight or bright lights

Risks and Complications

While laser eye surgery is generally safe, as with any medical procedure, there are some risks. These may include:

  • Dry eyes: A temporary side effect that can be managed with lubricating eye drops.
  • Glare or halos: Especially in low-light conditions, which can improve over time.
  • Under or over-correction: In some cases, further procedures may be necessary to refine the results.
  • Infection: Though rare, infection can occur, which is why following aftercare instructions is crucial.

Laser eye surgery is an excellent option for many people looking to improve their vision and eliminate the need for glasses or contact lenses. With advancements in technology, procedures like LASIK, PRK, and SMILE offer safe, effective, and minimally invasive solutions for a wide range of vision problems. If you’re considering laser eye surgery, consult with an experienced ophthalmologist to determine if it’s the right choice for you and to ensure a successful outcome. With proper care and attention, you could enjoy clearer vision and a better quality of life.
