For people who rely on glasses or contact lenses every day, LASIK may be an option worth considering. This type of laser eye surgery is designed to correct refractive errors and reduce dependence on vision aids. However, LASIK is not suitable for everyone, so understanding the procedure and having a proper eye examination are important steps before treatment.
What Is LASIK?
LASIK, or Laser-Assisted In Situ Keratomileusis, is a laser eye surgery that changes the shape of the cornea to improve how light focuses on the retina. The procedure is commonly used to correct nearsightedness, farsightedness, and astigmatism.
The goal is to improve unaided vision, although the results and suitability of treatment can vary from person to person.
Who Can Have LASIK?
Not everyone with a refractive error is automatically a candidate for LASIK. An ophthalmologist will usually assess several factors before recommending treatment, including:
- Stability of your prescription
- Corneal thickness and shape
- Overall eye health
- Dry eye symptoms
- Medical and eye history
A detailed eye examination helps determine whether LASIK is appropriate and which vision correction option may be more suitable.
LASIK and Other Laser Eye Surgery Options
Laser vision correction has several techniques, and each method has different approaches, recovery times, and suitable candidates.
- LASIK: Creates a thin corneal flap before reshaping the cornea with a laser. It is commonly used to correct nearsightedness, farsightedness, and astigmatism, with relatively quick visual recovery.
- FemtoLASIK: Similar to LASIK but uses a femtosecond laser to create the corneal flap. The technique may be recommended based on the patient’s corneal condition and overall eye health.
- ReLEx SMILE: Uses a femtosecond laser to create and remove a small piece of corneal tissue through a small opening. It does not require a large corneal flap and is commonly used for nearsightedness and astigmatism.
- PRK: Reshapes the cornea without creating a corneal flap. The surface layer of the cornea needs time to heal, so recovery is generally longer than LASIK.
How to Prepare for LASIK
Preparation starts before the day of surgery. Patients may need to stop wearing contact lenses for a period recommended by their doctor because contact lenses can temporarily affect the shape of the cornea.
Before treatment, it is also helpful to:
- Get a comprehensive eye examination
- Tell your doctor about medical conditions and medications
- Avoid eye makeup before the procedure
- Get enough rest
- Arrange transportation home after surgery
Following the clinic’s instructions can help make the treatment process smoother.
What to Expect After LASIK
Some patients may experience temporary symptoms such as dry eyes, mild irritation, light sensitivity, or changes in how lights appear at night. These effects can vary depending on the individual and the type of procedure performed.
During recovery, patients should use prescribed eye drops, avoid rubbing their eyes, and attend follow-up appointments as recommended. Activities such as swimming or contact sports may also need to be avoided for a period of time.
If you experience severe pain, significant redness, or a noticeable decrease in vision, contact your eye care provider promptly.
How Long Does LASIK Last?
LASIK results can be long-lasting, but they do not prevent natural changes in vision over time. As people age, presbyopia may develop and make it harder to focus on nearby objects. Some people may therefore need reading glasses later in life.
This does not necessarily mean that the original LASIK treatment has failed. It is part of the natural aging process of the eyes.
