What You Need to Know

In today’s digital age where screens dominate our daily lives, vision problems such as nearsightedness, farsightedness, and astigmatism have increased. While glasses and contact lenses provide effective correction, many people are turning to a more permanent solution: laser eye surgery.

 

Laser eye surgery has revolutionized vision correction, allowing patients to reduce or eliminate their reliance on corrective eyeglasses. But like any treatment, there are benefits, risks, and precautions. This article provides a comprehensive overview of laser eye surgery, including the types, benefits, risks, and what to expect before and after the procedure.

 

What is laser eye surgery?

Laser eye surgery is a category of surgery that uses a laser to reshape the cornea to correct refractive vision problems. By changing the way light is focused on the retina, laser surgery can significantly improve vision.

 

Some of the most common conditions treated with laser eye surgery include;

Myopia (nearsightedness) – difficulty seeing distant objects.

Farsightedness (hyperopia) – difficulty seeing close objects.

Astigmatism – blurred vision due to an irregular shape of the cornea.

Types of Laser Eye Surgery

 

There are many types of laser eye surgery, each with specific techniques and application scenarios. The most common include;

1. LASIK (laser-assisted in situ keratomileusis).

LASIK is the most popular form of laser eye surgery. It involves creating a thin flap in the cornea with a microkeratome or femtosecond laser, and then replacing the underlying corneal tissue with an excimer laser. The flap is then reattached.

Benefits

 

Treatment

Minimal disruption

Immediate improvement in vision

2. PRK (photorefractive keratectomy).

PRK is an alternative to LASIK for patients with thin corneas or dry eyes. Instead of a flap, the outer layer of the cornea is removed and the underlying tissue is reshaped.

 

Advantage

The absence of a corneal flap reduces complications related to the flap.

Ideal for people with active lifestyles or specific jobs.

3. SMILE (small-split lenticular extraction).

SMILE is a new, minimally invasive procedure that removes small pieces of tissue (the lens) through small incisions and reshapes the cornea.

Advantage

 

Smaller incisions than LASIK

Reduced dry eye symptoms after surgery

Quicker recovery for some patients

Benefits of laser eye surgery

Laser eye surgery offers many benefits, which is why it is becoming increasingly popular around the world.

1. Improvement in appearance

 

The most obvious benefit is dramatically improved vision. Most patients achieve 20/25 or better vision, often eliminating the need for glasses or contacts.

2. Fast recovery

For most patients, vision improves within 24 to 48 hours after LASIK or SMILE. Although PRK takes a little longer to heal, full recovery usually takes a few weeks.

3. Long-lasting results

For many people, laser eye surgery can permanently improve their vision. Although eyebrows can change with age, the effects of surgery usually last for decades.

4. Freedom from corrective glasses.

For those who are tired of wearing blurry glasses or contacts, laser eye surgery can offer new freedom and comfort.

5. Safe and proven technology

Modern laser eye surgery has evolved over decades and is now considered a safe and risk-free procedure when performed by an experienced surgeon.

What to expect: Before, during and after surgery

 

Before surgery

A detailed eye exam will be performed to evaluate your vision and eye health.

Your surgeon will explain the procedure, risks, and expected results.

You may need to stop wearing contact lenses a few weeks before surgery.

During surgery

The procedure usually takes 10 to 15 minutes per eye.

Eye drops are used to cool your eyes.

Lasers are used to reshape your cornea according to your specialist’s instructions.

After surgery

 

Most patients go home within a day with a protective eye shield.

Vision recovers within hours or days, depending on the technique used.

Follow-up appointments are necessary to monitor healing.

Avoid strenuous activity, rubbing eyes, and water exposure for a few weeks.

 

Decision

Laser eye surgery has changed the lives of millions of people, allowing them to see clearly without the use of glasses or contacts. There are many different methods available, so it is important to consult with an ophthalmologist to determine what is best for your eyes.

Despite the benefits, it’s important to understand the risks and set realistic expectations to make an informed decision. When performed by experienced professionals, laser eye surgery is a safe, effective, and life-prolonging procedure for many people around the world.
