Laser Eye Surgery Myths: What You Really Need to Know
Laser Eye Surgery Myths: What You Really Need to Know
Laser eye surgery is a safe, effective, and life-changing procedure that has helped millions of people achieve clear vision without glasses or contact lenses. Despite its proven success, several persistent myths continue to create unnecessary hesitation.
Let’s address the most common misconceptions and clarify the facts.
Myth 1: Laser Eye Surgery Can Make You Go Blind
False.
Serious complications from laser vision correction are extremely rare. Like all surgical procedures, there are risks, but they are very low.
- Risk of significant corneal haze: less than 1 in 2,000
- Risk of infection: approximately 1 in 5,000
By comparison, the risk of eye infection from contact lens wear is significantly higher. With modern technology and experienced surgeons, laser eye surgery has an excellent safety profile.
Myth 2: It’s Cheaper to Stick with Glasses or Contact Lenses
False.
While laser eye surgery involves an upfront investment, it is often more cost-effective over time.
Over 20–30 years, the ongoing cost of:
- Glasses
- Contact lenses
- Prescription sunglasses
- Cleaning solutions
can exceed tens of thousands of dollars.
Laser vision correction offers a long-term solution, reducing ongoing expenses while improving convenience and quality of life.
Myth 3: Laser Eye Surgery Wears Off Over Time
False.
Laser vision correction provides a permanent change to the shape of the cornea, correcting refractive errors such as myopia, hyperopia, and astigmatism.
In some cases, a natural healing response known as regression may slightly affect results, and an enhancement procedure may be required. This is uncommon and carefully considered during treatment planning.
It is also important to understand that natural ageing changes, such as presbyopia (loss of near vision), can occur over time. These are not caused by laser surgery and can be managed with additional treatment options if needed.
Myth 4: Laser Eye Surgery Is Painful
False.
Laser eye surgery is quick and generally painless.
- Numbing eye drops are used before and during the procedure
- Most patients feel only mild pressure, not pain
- Mild discomfort after surgery is temporary and easily managed
The majority of patients are surprised at how comfortable the procedure is.
Myth 5: The Laser Can Burn Your Eye
False.
Laser eye surgery uses highly controlled, medical-grade technology designed specifically for precision and safety.
- The excimer laser is a “cold laser” that reshapes the cornea without generating heat
- The femtosecond laser uses ultra-fast pulses to create precise tissue separation
Advanced systems, such as the Schwind AMARIS platform, include thermal control to protect surrounding tissue and ensure safety throughout the procedure.
Myth 6: If You Move, the Surgery Will Fail
False.
Modern laser systems are equipped with advanced eye-tracking technology that monitors and adjusts for eye movement in real time.
- Tracks eye movement in multiple dimensions
- Compensates instantly—over 1,000 times per second
- Anticipates movement for enhanced accuracy
Additionally, a small device gently keeps your eyelids open, so blinking is not a concern.
Myth 7: Laser Eye Surgery Changes Your Eye Colour
False.
Laser vision correction only treats the cornea, the clear front surface of the eye.
The iris, which determines eye colour, sits behind the cornea and is not affected by the procedure.
Your appearance remains exactly the same—just without the need for glasses or contact lenses.
Final Thoughts
Laser eye surgery is one of the most well-established and reliable procedures in modern ophthalmology. With over 30 years of clinical success, it offers a safe, precise, and long-term solution for vision correction.
Misinformation should never be a barrier to better vision. A comprehensive consultation is the best way to determine whether laser eye surgery is right for you.
