Laser eye surgery has helped around 30 million people worldwide see better over the past four decades, numbers paint a clear picture of laser eye surgery risk. A remarkable 91% of LASIK procedures hit their target correction for myopia or astigmatism within 1.0 dioptre after 3-12 months. These fantastic results explain why more people now choose laser surgery to ditch their glasses and contact lenses.
The procedure is relatively safe, too. Serious problems are rare only one in 5000 patients needs additional surgery to fix damaged corneal tissue. Contact lens wearers face higher risks, with one in 3000 developing serious corneal infections each year. Laser eye surgery pays off in the long run, even with its upfront costs. The success rates for touch-up procedures are also very high. This piece will walk you through different laser eye surgery options. You’ll learn who might need extra caution, how doctors check if you’re a good candidate, and what you should know before making this vision-changing choice.
Types of Laser Eye Surgery and Their Risk Profiles
Laser eye surgery comes in different types, and each has its own set of risks. You need to know these details before choosing this option to correct your vision.
LASIK: benefits and potential complications
LASIK (Laser-Assisted in Situ Keratomileusis) stands as the most popular laser eye surgery today. The surgeon creates a thin flap in your cornea and lifts it to let an excimer laser reshape the tissue beneath. This helps fix refractive errors like nearsightedness, farsightedness, and astigmatism. LASIK patients usually see clearly within 24 hours, but the procedure has its risks. Patients often experience temporary dry eyes that can last up to six months and might see glare and halos at night. Some rare but serious issues include under- or overcorrections, problems with the flap, and, in rare cases, loss of vision.
LASEK and PRK: surface procedures explained
LASEK (Laser Epithelial Keratomileusis) and PRK (Photorefractive Keratectomy) work on the cornea’s surface layer, which makes doctors call them “surface procedures”. These treatments handle the epithelial layer differently. LASEK keeps and puts back this layer after surgery. At the same time, PRK removes it completely and lets a new layer grow back naturally. People with thinner corneas (less than 490-500 microns) or active lifestyles make great candidates for these procedures. Recovery takes longer than LASIK – usually 4-7 days, and vision keeps improving over several weeks.
SMILE: newer technique with fewer flap risks
SMILE (Small Incision Lenticule Extraction) brings the latest innovation in laser eye surgery. The surgeon uses a femtosecond laser to create a small disc-shaped piece of tissue inside your cornea and removes it through a tiny keyhole opening, no flap needed. This method brings great benefits. Patients enjoy better corneal stability, less risk of dry eyes, and faster recovery. The absence of a flap means zero risk of flap-related complications, which cause up to 6.95% of problems in LASIK surgeries. Each eye takes about ten minutes to treat, with the laser working for just 25 seconds. This speed and efficiency make SMILE an increasingly popular choice for qualified patients.
Who Is Most at Risk?
Several factors can affect whether you’re a good candidate for laser eye surgery. Knowing these risk factors helps you make better decisions about your vision correction experience.
Patients with high prescriptions
Your prescription strength determines the safety limits for laser vision correction. Short-sightedness (myopia) has a safe limit that typically ranges from -8 to -10 dioptres. Long-sightedness (hyperopia) usually stays between +4 and +6 dioptres. Higher prescriptions need more corneal tissue removal, which increases risks. High astigmatism (above 3.00 dioptres) needs precise reshaping and usually requires customised laser patterns. Some patients might find other vision correction methods safer in these cases.
Thin corneas and corneal shape issues
Corneal thickness is a vital factor in determining if you qualify for laser surgery. Patients face higher risks when their central corneal thickness falls below 480 microns. The cornea needs enough tissue for safe reshaping. Without it, patients might develop post-operative complications. One such issue is corneal ectasia, where the cornea bulges forward and distorts vision. Irregular corneal shapes might point to underlying weakness or conditions like keratoconus. These conditions make laser procedures unsafe.
Pre-existing dry eye or eye conditions
Dry eye conditions can really impact your surgery results. About half of LASIK patients notice some dry eye symptoms after surgery. The risks go up for people who already have severe, untreated dry eye disease, significant corneal staining, or very low tear volume. Eye conditions like macular degeneration, glaucoma, or moderate-to-advanced cataracts usually mean laser procedures won’t work.
Age-related considerations
Age substantially affects your suitability for the procedure. Most people develop presbyopia in their mid-40s or 50s. This condition makes it hard to read close objects because the eye’s internal lens becomes stiff. Laser procedures reshape the cornea but can’t fix lens stiffening, so they might not entirely correct presbyopia. Older adults produce fewer tears, which can lead to longer-lasting dry eye symptoms after surgery. Lens-based procedures often work better for seniors and provide more detailed solutions.

Making an Informed Decision
You need to think over several significant factors and do thorough research before deciding if laser eye surgery suits you.
Questions to ask during your consultation
The best way to get value from your consultation is to ask specific questions about your case:
- Which procedure matches my prescription and lifestyle?
- What vision improvements should I expect?
- How will recovery impact my daily life?
- What’s included in your aftercare package?
Understanding your personal risk profile
85% of adults qualify for some type of vision correction. Your eligibility depends on your age (over 18), stable prescription (unchanged for 12-24 months), and overall eye health. Precision Vision London’s advanced diagnostic technology maps your cornea’s unique characteristics. It gives a complete picture of your individual risk factors.
Balancing benefits vs. potential side effects
Less than 1 in 5000 patients need additional surgery to replace damaged tissue after laser eye surgery. The risk looks different when you know that 1 in 3000 contact lens wearers develop serious corneal infections each year. These numbers help you see what it all means when weighing the benefits of life without corrective eyewear.
Why trust matters in choosing a clinic
Qualified surgeons must register with the General Medical Council and be on the specialist register in ophthalmology. Yes, it is vital that your chosen surgeon has specialist fellowship training in refractive surgery and regularly performs many procedures each month.

FAQs
Q1. How safe is laser eye surgery compared to wearing contact lenses? Laser eye surgery is generally considered safer than long-term contact lens wear. Serious complications occur in fewer than 1 in 5,000 laser eye surgery patients. At the same time, about 1 in 3,000 contact lens wearers develop serious corneal infections annually.
Q2. What are the most common side effects of laser eye surgery? The most common side effects include temporary dry eyes, which can last up to six months, and night vision disturbances such as glare and halos. These symptoms typically resolve within a few weeks to months after the procedure.
Q3. How long does it take to recover from laser eye surgery? Recovery time varies depending on the type of procedure. LASIK patients often see clearly within 24 hours, while surface procedures like LASEK and PRK may take 4-7 days for initial recovery, with full vision improvement occurring over several weeks.
Q4. Who might not be suitable for laser eye surgery? Individuals with very high prescriptions (beyond -10 dioptres for short-sightedness or +6 dioptres for long-sightedness), those with thin corneas (below 480 microns), people with severe dry eye disease, and those with certain pre-existing eye conditions may not be suitable candidates.
Q5. What should I look for when choosing a laser eye surgery clinic? Look for a clinic with highly qualified surgeons who have extensive experience in refractive surgery. The clinic should use cutting-edge diagnostic and laser technology, offer personalised treatment planning, and provide comprehensive aftercare. Ensure the surgeon is registered with the General Medical Council and on the specialist register in ophthalmology.
