Refractive surgery removes the need for glasses or contact lenses by reshaping your cornea using precise excimer lasers. Like cataract surgery, this eye procedure has proven remarkably successful – with over 18 million LASIK treatments worldwide and 95.4% of patients reporting satisfaction with their results.
Talk with your eye doctor about whether refractive surgery is right for you. The procedure offers several options for treating vision problems like nearsightedness, farsightedness, and astigmatism. Your doctor will carefully evaluate your eyes to determine if you’re a good candidate for the surgery. The success of your procedure depends on proper patient selection and maintaining strict surgical standards.
This guide explains what you need to know about refractive surgery – from understanding different procedures to preparing for surgery and recovery. Your doctor will help you choose the most suitable treatment based on your specific vision needs and eye health.
What is Refractive Surgery?
Our natural lens and cornea work together to focus light properly on the retina. When they don’t function correctly, you may need glasses or contact lenses. Refractive surgery adjusts how light enters your eye by reshaping the cornea or modifying the lens. These procedures have become increasingly sophisticated, helping millions of people worldwide see clearly without corrective lenses.
How refractive surgery works
The cornea handles most of your eye’s focusing power – over 70%. During refractive surgery, your eye doctor either reshapes your cornea or adjusts your eye’s natural lens to improve how light focuses on your retina.
Most commonly, doctors use excimer lasers to reshape the cornea’s curvature with extreme precision. For some people, lens implantation or replacement might work better, depending on their specific vision problems.
Two main approaches to refractive surgery exist:
- Corneal Surgery: Uses precise laser techniques to reshape your cornea
- Lens Surgery: Places artificial lenses or exchanges your natural lens
These procedures show excellent results for safety and predictability. Studies from the Magill Research Center for Vision Correction found that 95.4% of patients feel satisfied after LASIK surgery.
Who needs refractive surgery
Vision problems affect many people worldwide – about 20-25% have myopia (nearsightedness), and over 75 million Americans use some form of vision correction.
Refractive surgery particularly helps:
- People whose jobs require clear vision without glasses
- Athletes and performers who can’t wear glasses during activities
- Those with stable vision prescriptions for 2-3 years or more
Talk with your eye doctor about whether you’re a good candidate. Most suitable patients:
- Are at least 18 years old
- Have maintained the same prescription for 1-2 years
- Show healthy corneas
- Have no major medical or eye conditions
However, refractive surgery isn’t right for everyone. You should avoid these procedures if you have:
- Keratoconus or thinning corneas
- Pregnancy or are nursing
- Autoimmune diseases or uncontrolled diabetes
- Glaucoma or severe dry eyes
Before surgery, your eye doctor will thoroughly examine your eyes using special tools like corneal mapping and thickness measurements to check for any problems. This helps ensure the chosen procedure matches your specific needs.
While refractive surgery can reduce your need for glasses or contacts, it’s important to understand its limitations. The procedure can’t treat conditions like glaucoma, cataracts, or other vision-damaging disorders. Also, like with cataract surgery, your vision may still change naturally as you age.
Types of Refractive Eye Surgery
Like cataract surgery options, refractive surgery offers several procedures to correct your vision problems. Your eye doctor will help determine which approach best suits your specific needs.
LASIK surgery
Laser-Assisted In Situ Keratomileusis remains one of the most common vision correction procedures. During this 30-minute surgery, your doctor creates a thin flap in your cornea’s outer layer using either a microkeratome or femtosecond laser. Much like how we reshape clay, an excimer laser then carefully reshapes the corneal tissue underneath to improve your vision.
About 96% of patients achieve their desired vision goals. Most people see better within days after surgery. However, you might notice temporary effects like sensitivity to light, dry eyes, or halos around lights at night.
PRK surgery
For some people, especially those with thin or irregular corneas, Photorefractive Keratectomy (PRK) offers a better solution. Unlike LASIK’s flap approach, PRK removes the cornea’s outer layer completely. Your eye naturally grows new tissue within five days.
The way cataract surgery needs time for full recovery, PRK takes longer than LASIK – your vision improves gradually over several weeks. During healing, you’ll wear a special contact lens bandage to protect your eye.
SMILE surgery
Small Incision Lenticule Extraction (SMILE) emerged in the 2010s. The FDA approved it for treating nearsightedness from -1 to -8 diopters and astigmatism up to -0.5 diopters. In 2018, they expanded approval for myopic astigmatism up to 3 diopters.
Think of SMILE like removing a tiny contact lens from within your cornea. Your doctor uses a femtosecond laser to create a small lens-shaped disk within the cornea, then removes this disk through a tiny 2.5mm opening. The results speak for themselves – 98% of patients achieve vision that meets driving standards.
Lens replacement surgery
Also called Refractive Lens Exchange (RLE), this procedure replaces your eye’s natural lens with an artificial one (IOL). The surgery takes about 15-30 minutes and effectively corrects various vision problems.
You can choose from three main lens types:
- Monofocal lenses – clear vision at one distance, usually far
- Multifocal lenses – good vision at multiple distances
- Toric lenses – specially designed for astigmatism
The safety record impresses – 98% of patients experience no serious complications. Like cataract surgery, these artificial lenses stay in your eye permanently.
How to Prepare for Refractive Surgery
Like cataract surgery, proper preparation helps ensure the best possible outcome from refractive surgery. Your doctor will guide you through several steps before scheduling your procedure.
Initial consultation
The first step involves a comprehensive consultation that typically lasts 2-3 hours. Think of this meeting like planning a journey – your eye doctor needs to make sure you’re ready for the trip.
During your consultation, your eye surgeon will:
- Review your medical history, looking for conditions that might affect your results
- Listen to your vision goals and daily needs
- Explain your treatment options
- Answer your questions about the surgery
Your doctor carefully evaluates both your general health and eye condition. For instance, if you have diabetes, autoimmune diseases, or certain vascular disorders, you’ll need special consideration since these conditions can affect how you heal.
Required medical tests
Before surgery, your doctor performs several specialized tests – much like the detailed examinations before cataract surgery. These tests help determine which procedure suits your eyes best.
Your detailed eye examination includes:
- Corneal Analysis
- Corneal topography to create a map of your cornea
- Pachymetry measures how thick your cornea is
- Wavefront analysis looks for subtle vision problems
- Vision Assessment
- Checks your current prescription
- Measures your pupil size
- Tests your tear quality
- Checks pressure in your eye
The day before surgery, stop using:
- Creams
- Lotions
- Makeup
- Perfumes
These products raise your risk of infection during and after surgery. If you wear contact lenses, you’ll need to stop wearing them before evaluation – one week for soft lenses, two weeks for toric lenses, and at least three weeks for rigid lenses.
Make sure someone can drive you home after surgery – you won’t be able to drive yourself. Your doctor might give you antibiotic eye drops to use 1-2 days before your procedure.
Take time to make your decision – don’t feel rushed by family, friends, or medical staff. Remember to:
- Read all information carefully
- Think about risks and benefits
- Ask questions if something isn’t clear
- Make sure you understand the consent form completely
Your overall health matters for refractive surgery success. Your doctor checks for any health conditions that might affect your outcome. This careful approach, like in cataract surgery, helps ensure you’re well-prepared for the procedure.
The Refractive Surgery Procedure
Much like cataract surgery, refractive surgery follows a careful step-by-step process. Understanding what happens during each phase helps reduce anxiety about your procedure.
Before the surgery
Plan to spend approximately two hours at the clinic. Your surgeon reviews the planned procedure and takes final measurements to ensure accuracy. You’ll receive mild sedatives to help you relax, along with numbing eye drops for comfort.
To prepare for surgery:
- Avoid heavy meals
- Wear comfortable clothes that button in front
- Come without makeup or fragrances
- Make sure your hair is clean
During surgery
The procedure takes about 10-15 minutes for each eye. Your surgeon helps you lie comfortably on a reclining chair, then places a small device called a lid speculum to gently hold your eyelids open.
For creating the corneal flap, your surgeon uses either:
- A mechanical microkeratome (blade device)
- A femtosecond laser (bladeless approach)
During surgery, you might notice:
- Some pressure when the suction ring goes on
- Your vision becoming dim at times
- Clicking sounds from the laser
- A slight burning hair smell
Talk with your eye doctor about whether surgery is right for you. Your surgeon guides you through each step, asking you to look at a specific light point. This light helps keep your eye in the right position. Like a careful guardian, the laser tracks your eye position 500 times every second, stopping automatically if your eye moves too much.
Immediate aftercare
After surgery, your surgeon places protective shields over your eyes. These shields, like the ones used after cataract surgery, protect your eyes from accidental rubbing while you sleep. You might experience:
- Burning or itching
- Watery eyes
- Slightly blurred vision
- Mild discomfort
Your doctor prescribes specific medications:
- Lubricating eye drops
- Antibiotic drops
- Steroid drops to control inflammation
For the first day:
- Keep your eyes closed for several hours
- Don’t rub your eyes
- Use eye drops as prescribed
- Keep protective shields on while sleeping
Most patients see better right away, though many say it’s like looking through a “dirty window” at first. Your vision typically becomes clearer within days, with about 90% of patients achieving their best possible vision shortly after surgery.
See your doctor within 24-48 hours after surgery. During this important visit, your surgeon:
- Takes off the eye shields
- Checks your vision
- Looks at how you’re healing
- Adjusts your medications if needed
Recovery and Results
Like after cataract surgery, your vision improves gradually after refractive surgery. Most of our patients see significant improvements within days. Let’s look at what you can expect during recovery.
First week after surgery
Your healing begins right away, with vision typically improving within 24 hours. You might experience:
- Mild discomfort or eye pain
- Dry or watery eyes
- Puffy eyelids
- Light sensitivity
- Blurred vision
We find that about one-third of patients report minimal discomfort, another third have mild pain, and the remaining third notice more noticeable discomfort. Artificial tears help manage these symptoms effectively – many of our patients find extra comfort when storing them in the refrigerator.
Long-term recovery
The way our natural lens takes time to heal after cataract surgery, complete recovery from refractive surgery typically spans three to six months. Your vision stabilizes gradually, with most patients achieving 90% of their best possible vision shortly after the procedure.
Your recovery journey usually follows these milestones:
- First Month: Your vision begins stabilizing, though some fluctuations are normal
- Three Months: Most side effects decrease significantly
- Six Months: Your final vision outcomes become clear
Talk with your eye doctor about dry eye syndrome – it affects about 30% of patients, usually peaking around three months but resolving within six to twelve months. Some patients notice glare, halos around lights, or have trouble seeing at night during this period.
Expected outcomes
Clinical studies involving over 9,000 participants between 1993 and 2005, along with more than 7,000 research studies, confirm the safety of these procedures. The results are impressive:
- 98% of patients achieve vision meeting driving standards
- More than 98% of patients with up to -7 diopters of nearsightedness and -3 diopters of astigmatism reach 20/20 vision
- About 99% of patients feel satisfied with their results
Just as with cataract surgery, your vision might change naturally as you age. About 5% of patients need enhancement procedures over their lifetime. These touch-up procedures can fine-tune your vision once your initial surgery has fully healed.
For the best long-term results:
- Keep all your follow-up appointments
- Use your prescribed medications as directed
- Protect your eyes from UV light
- Have regular eye check-ups
We’re encouraged by research showing excellent safety even after ten years. Most patients enjoy clear vision without glasses or contacts for many years after surgery.
