What is LASIK surgery?

LASIK (Laser-Assisted In Situ Keratomileusis) surgery is a type of refractive surgical procedure designed to correct vision problems such as nearsightedness, farsightedness, and astigmatism. It aims to improve vision by reshaping the cornea, which allows light rays to focus more accurately on the retina. An eye surgeon uses a laser to reshape the cornea, adjusting its curvature to match the patient’s specific refractive error. This reshaping helps correct the refractive error, allowing light to be properly focused for clearer vision.

LASIK surgery can significantly reduce or eliminate the need for glasses or contact lenses but LASIK surgery is not suitable for everyone, as certain conditions like thin corneas or severe dry eyes may disqualify a person from undergoing the procedure. An eye surgeon will conduct a thorough evaluation to determine if LASIK is appropriate for each patient. Despite these considerations, LASIK remains a popular and effective method for correcting vision problems and enhancing quality of life.

What is done in LASIK surgery?

In LASIK surgery, an eye surgeon uses a laser to reshape the cornea, adjusting its curvature to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. The procedure begins with the creation of a thin flap in the cornea, which is achieved using a microkeratome or femtosecond laser. The flap is then carefully folded back to expose the underlying corneal tissue. Once the corneal tissue is accessible, the surgeon uses a laser to reshape the shape of the cornea according to the patient’s specific needs.

This reshaping allows light rays to focus properly on the retina, resulting in improved vision. During the surgery, a suction ring is used to stabilize the eye and ensure precision during the procedure. After the corneal reshaping is complete, the corneal flap is repositioned and allowed to heal naturally. LASIK surgery can significantly reduce or eliminate the need for glasses or contact lenses and offers a rapid recovery time for most patients.

Does LASIK correct eyes permanently?

LASIK surgery can provide long-lasting vision correction by reshaping the cornea, effectively improving the way light rays enter the eye. For many patients, the correction remains stable for years or even decades. However, LASIK may not provide a permanent solution for everyone. As people age, their vision can naturally change, which may require the use of reading glasses or other vision aids over time. Regular follow-up with an eye surgeon can help monitor any changes.

What is the purpose of LASIK eye surgery?

The purpose of LASIK eye surgery is to correct vision problems caused by refractive errors such as nearsightedness, farsightedness, and astigmatism. By reshaping the cornea with a laser, LASIK improves how light rays focus on the retina, resulting in clearer vision. This surgical procedure aims to reduce or eliminate the need for glasses or contact lenses, thereby enhancing overall quality of life for patients

Is LASIK surgery painful?

LASIK surgery is generally not painful because numbing eye drops are applied to the eye before the procedure. Patients may feel slight pressure from the suction ring, but it’s not typically described as painful. Post-surgery, some may experience temporary side effects such as dry eyes or mild discomfort, which usually subside quickly during the healing process.

Who is LASIK not suitable for?

LASIK surgery is not suitable for everyone. Some people with specific eye conditions like thin corneas or severe dry eyes may not be suitable for the procedure as it can increase the chances of complications. Additionally, individuals with unstable vision, autoimmune diseases, or certain health conditions may not be recommended for LASIK. Pregnant or nursing women are usually advised to avoid LASIK due to hormonal changes that can impact vision stability. To determine if LASIK is appropriate, an eye surgeon will carefully evaluate the patient’s medical history and eye health.

How long does LASIK take?

The actual LASIK procedure is quite fast, typically taking around 10-15 minutes per eye. This includes the time needed to create the corneal flap, reshape the corneal tissue using the laser, and reposition the flap. However, patients should expect to spend additional time at the surgical facility for preparation and post-operative care, including receiving instructions on how to care for their eyes after the surgery.

What is the most appropriate age for LASIK eye surgery?

The most appropriate age for LASIK eye surgery is generally when a patient’s vision has stabilized, which usually occurs in the mid-20s. It is not recommended for individuals under 18, as their vision may still be changing. An eye surgeon can assess whether a patient is a suitable candidate based on their age, vision stability, and other factors.

FAQ

Will I need glasses after LASIK?

After LASIK, many patients experience significant improvement in their vision and may no longer need glasses or contact lenses for most activities. However, as patients age, they may develop presbyopia, which could necessitate reading glasses. Regular check-ups with an eye surgeon can help monitor vision changes over time.

What happens if I sneeze during LASIK?

During LASIK surgery, the eye is kept stable using a suction ring. This ensures that any unexpected movements, such as sneezing, will not disrupt the procedure. The laser automatically stops if there is movement, so there is minimal risk of complications due to sneezing.

Do you sleep during LASIK?

No, you do not sleep during LASIK. The procedure is performed while you are awake, but numbing eye drops are applied to prevent pain and discomfort. Patients remain conscious throughout the surgery and can follow the eye surgeon’s instructions. This ensures that the procedure is safe and efficient.

Can I blink during LASIK?

While patients might feel the urge to blink, the surgeon uses special equipment to keep the eye in position during LASIK. This equipment prevents blinking and ensures that the procedure goes smoothly without interruptions.

Is it okay to cry after LASIK?

After LASIK, it’s okay to cry, as this can help keep the eyes lubricated. However, patients should avoid rubbing or touching their eyes to prevent displacing the corneal flap. If excessive tearing or discomfort occurs, patients should consult their eye surgeon for guidance.
