Can You Go Blind From Laser Eye Surgery?

Laser eye surgery has transformed the lives of millions around the world. Whether you’re tired of wearing contact lenses or dealing with fogged-up glasses, the promise of clearer vision through a short and relatively simple surgical procedure is incredibly appealing. But understandably, you may be wondering: Can you go blind from laser eye surgery? It’s a reasonable concern and one we’ll address in depth.

In this article, we’ll explain everything you need to know about the precision of laser eye surgery, including an honest, professional assessment of the risks, particularly the extremely rare risk of blindness.

Our focus is on helping you make a wise decision based on expert insights. We’ll also explore the cost of laser eye surgery, the healing process, different types of procedures, and what to expect during and after treatment.

So, let’s dive in.

What Is Laser Eye Surgery?

Laser eye surgery, or refractive eye surgery, refers to surgical procedures designed to correct vision problems caused by refractive errors such as short-sightedness (myopia), long-sightedness (hyperopia), and astigmatism.

Most Common Types

Several types of laser eye surgery are widely performed in Australia today. Each has its own unique approach and may be recommended based on individual eye health, lifestyle, and vision goals:

• LASIK surgery (Laser-Assisted In Situ Keratomileusis)
• PRK (Photorefractive Keratectomy)
• SMILE (Small Incision Lenticule Extraction)
• PRESBYOND (Laser Blended Vision)

Purpose Of Laser Eye Surgery

The main goal of laser eye procedures is to adjust the shape of the cornea so that light entering the eye is adequately focused onto the retina. This helps correct vision and reduce or eliminate the need for glasses or contact lenses.

Is Laser Eye Surgery Safe?

Laser eye surgery is considered precise when performed by an experienced eye surgeon. Modern laser eye surgery has an extremely low complication rate, with most patients achieving significantly improved vision.

Extensive clinical studies and decades of practice show that LASIK and other laser eye surgeries are effective and low-risk for most patients.

Can You Go Blind From Laser Eye Surgery?

While it is technically possible to experience vision loss or even go blind from laser eye surgery, such outcomes are typically rare. Most mild and temporary complications, such as dry eyes or blurry vision, can be managed effectively.

Here are the things that might lead to vision loss:

• Severe infection
• Corneal ectasia (thinning and bulging of the cornea)
• Unrecognised pre-existing eye conditions
• Traumatic injury during the healing process

Why Is Blindness Uncommon?

Thanks to advanced technology, rigorous screening processes, and expert care, laser eye surgery has an exceptionally low complication rate, especially when performed by qualified professionals in regulated clinical environments.

Below are some of the key reasons why blindness is not a typical outcome of modern refractive eye surgery:

Cutting-Edge Technology

Today’s laser eye surgery systems have advanced mechanisms that greatly reduce the risk of error.

For instance, high-speed eye-tracking technology monitors even the tiniest involuntary eye movements during the procedure, allowing the laser to remain perfectly aligned throughout treatment.

These smart systems pause automatically if your eye moves out of range, ensuring precise laser application.

Thorough Pre-Surgical Screening

Every individual considering laser eye surgery undergoes an in-depth consultation and comprehensive eye assessment before proceeding. This includes evaluating your corneal thickness, eye health, tear production, and the stability of your refractive error.

These assessments help determine whether you’re a good candidate for the procedure, significantly lowering the chances of complications and ensuring the treatment is tailored to your unique vision profile.

Expert Care By Qualified Professionals

The risk of serious complications is exceptionally low when experienced eye surgeons and ophthalmologists perform laser eye procedures in accredited clinics.

In Australia, these practitioners follow strict clinical guidelines and ethical standards set by governing bodies like AHPRA, further contributing to patient safety. Their training, precision, and ongoing commitment to excellence mean you’re in highly capable hands from start to finish.

What Happens During The Procedure?

Understanding what happens during laser eye surgery can help ease any nervousness. The process is carefully planned, precise, and typically very efficient, performed in a calm, clinical setting by an experienced surgical team.

Here’s a step-by-step breakdown of what you should expect on the day of your procedure:

1. Creation Of The Flap Or Small Incision

In LASIK eye surgery, a very thin flap is created on the surface of your cornea using a femtosecond laser.

If you’re undergoing SMILE (Small Incision Lenticule Extraction), a tiny incision is made instead without a flap. The approach depends on the type of refractive surgery recommended for your specific vision needs.

2. The Laser Reshapes The Cornea

A computer-guided excimer laser carefully reshapes the corneal tissue beneath the flap or through the incision.

This is the key step in vision correction, as it tweaks how light is focused onto the retina, helping to address refractive errors such as short-sightedness, long-sightedness, or astigmatism.

3. Repositioning The Flap (If Applicable)

Once the reshaping is complete, the corneal flap is gently repositioned for LASIK procedures. No stitches are required; the flap naturally adheres back into place and begins healing immediately. In SMILE and PRK, this step is not needed.

Duration Of The Procedure

The entire laser eye surgery treatment is typically completed in less than 30 minutes for both eyes. The actual time the laser is applied is often just a few seconds per eye. Most patients are surprised by how quick and smooth the experience is.

The Healing Process

Your healing journey begins immediately after your laser eye surgery procedure, and for most patients, it’s smoother than expected. While everyone heals at their own pace, here’s what you may notice in the early stages of recovery:

• Blurry vision at first: It’s completely normal for your vision to appear a little foggy or soft straight after surgery. This usually begins to clear within the first day.
• Temporary Dry Eyes: Many patients experience mild dryness or a gritty sensation. Lubricating eye drops will be prescribed to keep your eyes comfortable.
• Slight Irritation or Watering: A bit of discomfort, tearing, or sensitivity to light can occur, but usually settles quickly.
• Ongoing Use of Eye Drops: You’ll need to use prescribed antibiotic and lubricating drops regularly to protect against infection and support your eye health.

Your laser eye surgeon will provide detailed aftercare instructions and guide you every step of the way to ensure a smooth and pleasant healing process.

Recovery Timeline

While healing times may vary slightly between individuals and types of procedures, the general timeline for recovery looks like this:

• First 24 hours: It’s important to rest your eyes as much as possible. Avoid screen time, wear your protective eye shield if advised, and keep your eyes closed when you can.
• Within A Few Days: Your vision will likely begin to stabilise. Around this time, most people can return to work and resume light activities.
• After A few Weeks: For most patients, visual clarity continues to improve and reaches its peak. Follow-up visits will help track your progress and ensure your recovery is on track.

Each stage of the healing process brings you closer to a clearer, sharper vision without needing glasses or contact lenses.

By following your surgeon’s advice and caring for your eyes properly, you’re setting yourself up for the best possible outcomes.

Frequently Asked Questions

Can I stop wearing glasses?

You should be able to reduce or eliminate your need for glasses or contact lenses. Results vary depending on your age, prescription, and eye health.

How much does laser eye surgery cost?

The cost of laser eye surgery can vary depending on factors like the type of procedure (LASIK, SMILE, or refractive lens exchange) and the clinic’s location. Some clinics offer interest-free payment plans or coverage options through private health insurance, which can help make the cost more manageable.

Is it possible to drive after eye laser surgery?

Most patients can drive within 24 to 48 hours after laser eye surgery, depending on how well their vision has stabilised. However, you should avoid driving until you’re comfortable and your doctor has given you the green light.

Does laser eye surgery hurt?

Before surgery, your eyes will be gently numbed using anaesthetic eye drops. These ensure that you remain comfortable throughout the procedure. You’ll be awake but not feel much pain, just mild pressure or coolness during certain steps.
