FAQs About Myopia Procedures: Surgical Options, Risks, and What to Expect
Explore common surgical treatments for nearsightedness, their risks, benefits, recovery, and how to choose the best myopia procedure for you.
Myopia, also known as nearsightedness, is a common vision problem that can make distant objects look blurry while close-up objects remain clear. While glasses and contact lenses have long been the main solutions, advances in surgical treatments are helping many reduce their reliance on corrective eyewear. This article answers the most frequently asked questions about myopia surgery—from LASIK and PRK to lesser-known procedures—so you can make an informed decision about your vision correction journey.
What Is Myopia and Why Does It Need Correction?
Myopia occurs when the eye is too long or the cornea is too curved, causing light rays to focus in front of the retina instead of directly on it. This makes distant objects appear out of focus. Myopia is commonly corrected with:
- Eyeglasses: The simplest and most common correction for myopia.
- Contact lenses: Soft or gas-permeable lenses fitted to the surface of your eye.
- Surgical procedures: Options for those seeking a long-term reduction in eyeglass or contact lens dependence.
While myopia cannot be permanently cured, these treatments can correct or dramatically improve vision clarity.
What Are the Most Common Surgical Procedures for Myopia?
Several surgical procedures are available for correcting myopia, each with unique methods, benefits, and considerations. Here’s a detailed overview:
1. Laser In-Situ Keratomileusis (LASIK)
- LASIK is the most popular myopia surgery.
- The surgeon creates a thin flap in the cornea, reshapes the underlying tissue with a laser, and replaces the flap.
- Typically results in minimal discomfort and rapid visual recovery.
- Recommended for mild to moderate myopia and suitable corneal thickness.
2. Photorefractive Keratectomy (PRK)
- PRK is similar to LASIK but does not involve creating a corneal flap.
- The outer layer of the cornea (epithelium) is removed, the tissue is reshaped with a laser, and the epithelium naturally grows back over several days.
- Usually chosen when the patient’s cornea is too thin for LASIK.
- PRK has a slightly longer recovery time but a lower risk of some flap-related complications.
3. Laser-Assisted Subepithelial Keratectomy (LASEK)
- LASEK is a hybrid of LASIK and PRK.
- The epithelial layer is loosened with alcohol, lifted, and replaced after laser reshaping of the cornea.
- Often used for thin or flat corneas.
- May have less postoperative pain than PRK but a longer visual recovery than LASIK.
4. Small Incision Lenticule Extraction (SMILE)
- SMILE uses a femtosecond laser to create a small, disc-shaped piece of tissue (lenticule) within the cornea, which is removed through a tiny incision.
- No flap creation is needed—leading to potentially fewer dry eye symptoms.
- Typically recommended for moderate to high myopia.
- Visual recovery is rapid; less post-surgical discomfort than PRK.

5. Automated Lamellar Keratoplasty (ALK)
- ALK is a less commonly used procedure today.
- Involves using a microkeratome (cutting device) without lasers to create a flap and remove a thin layer of corneal tissue.
- Mainly reserved for severe cases or when laser procedures are unsuitable.
6. Intracorneal Ring Segments (Intacs)
- Clear plastic segments are implanted into the cornea to flatten it and adjust focus.
- Primarily used for myopia with co-existing keratoconus (a corneal thinning disorder).
- Vision improvement is usually more modest than with LASIK or PRK.
7. Refractive Lens Exchange (RLE) / Clear Lens Extraction (CLE)
- The natural eye lens is removed and replaced with an artificial intraocular lens (IOL), similar to cataract surgery.
- Indicated when significant lens abnormalities or extremely high myopia are present, or when corneal surgery is not advisable.
- RLE may increase the risk of retinal detachment in highly myopic eyes.
8. Phakic Intraocular Lens (PIOL)
- An artificial lens is implanted into the eye without removing the natural lens.
- Suitable for high degrees of myopia where corneal refractive surgery is not possible.
- Unlike RLE, the eye’s natural ability to accommodate (focus at near) is preserved.
9. Radial Keratotomy (RK)
- RK involves making radial cuts on the cornea with a blade, causing it to flatten for refractive correction.
- Now rarely performed due to potential long-term complications and the availability of more precise laser procedures.
- Historically gave good initial results but risks of instability and other side effects emerged over time.
What Are the Benefits and Risks of Myopia Surgery?
Most myopia procedures offer significant improvements in vision, often to 20/20 or close. However, results depend on the individual, degree of myopia, and the procedure selected. Consider these benefits and risks:
- Benefits:
- Reduction or elimination of dependence on glasses/contact lenses.
- Quick recovery of functional vision, especially with LASIK and SMILE.
- Improved quality of life in activities such as sports and travel.
- Risks and Side Effects:
- Temporary visual disturbances: glare, halos, and dry eyes are common, especially immediately after surgery.
- Flap complications (with LASIK): rare but possible.
- Regression or over/undercorrection: may require enhancement or retreatment.
- Infection and delayed healing: uncommon with appropriate care.
- Permanent loss of best-corrected vision or new visual distortions: rare but a risk of any refractive surgery.
It’s important to discuss your unique risk profile with your eye surgeon before proceeding.
Who Is a Candidate for Myopia Surgery?
Not every person with myopia is a good candidate for surgical vision correction. You may be considered eligible if you:
- Are at least 18 years old
- Have had a stable eyeglass prescription for at least one year
- Have healthy eyes (no active eye disease or severe dry eye)
- Have realistic expectations about outcomes and risks
- Have adequate corneal thickness (for corneal-based procedures)
Contraindications may include pregnancy, certain autoimmune diseases, progressive myopia, or specific corneal or retinal conditions. A thorough eye examination is critical to determine candidacy.
How Do I Choose the Best Myopia Procedure for Me?
The best myopia procedure depends on:
- The degree and type of your myopia
- Corneal thickness and shape
- Presence of other eye conditions (e.g., keratoconus, cataracts)
- Age and visual needs
- General health
Work closely with your ophthalmologist to review your eye health, lifestyle, and desired outcomes before choosing a surgical option.
What Should I Expect Before, During, and After Surgery?
Before Surgery
- Comprehensive eye exam and detailed history by an ophthalmologist or refractive surgeon.
- Measurements of corneal thickness, shape, and pupil size.
- Contact lenses may need to be discontinued prior to some surgeries for accurate measurement.
- Discussion of expectations, alternatives, risks, and benefits.
During Surgery
- Eye numbing drops are used for comfort.
- Most procedures are done on an outpatient basis and last less than 30 minutes per eye.
- Patients are awake, but mild sedatives may be given.
- LASIK/PRK/SMILE: Laser work typically takes only a few minutes.
- Lens procedures (PIOL/RLE): Usually slightly longer but still completed quickly.
After Surgery
- Blurry vision is common for the first several hours to days, depending on the procedure. Vision usually stabilizes over 1-3 months.
- Eye drops (antibiotics, steroids, lubricants) are prescribed to promote healing and prevent infection.
- Follow-up visits are essential to monitor healing and early detection of any complications.
- Avoid rubbing your eyes, strenuous activity, and water exposure (swimming) in the first week as directed.
How Long Do Myopia Surgery Results Last?
For most people, the benefits of myopia surgery are long-lasting, though age-related changes (such as presbyopia or cataracts) can affect vision over time. Some patients, particularly those with high myopia or younger patients, may experience regression requiring retreatment or minor corrective lens use later in life.
Laser procedures like LASIK or SMILE have high rates of satisfaction and lasting results, while lens-based procedures may also treat or prevent future cataracts.
What Are the Costs and Insurance Coverage for Myopia Procedures?
Myopia surgery is typically classified as elective and not covered by most insurance plans. The average costs in the U.S. vary by procedure, provider, and region:
- LASIK: $2,000–$3,000 per eye
- PRK/LASEK: Slightly less expensive than LASIK
- SMILE: Comparable to or slightly higher than LASIK
- Lens procedures (PIOL/RLE): $3,000–$5,000 per eye or more
Financing options and health savings accounts (HSA/FSA) can help manage out-of-pocket expenses. Ask your surgeon’s office for a detailed breakdown of costs, including post-surgery care.
Frequently Asked Questions (FAQs) About Myopia Procedures
Q: Can myopia surgery permanently cure my nearsightedness?
A: No surgical procedure can cure myopia forever, as eye shape can change over time, but the vast majority of patients enjoy dramatically improved vision for years. Some may still need glasses for certain activities or as they age.
Q: Is myopia surgery painful?
A: Most people experience little to no pain during the procedure. Afterward, LASIK and SMILE usually cause only mild discomfort or dry eye for a few days. PRK and LASEK can result in more pronounced irritation during initial healing.
Q: How soon can I return to work or normal activities?
A: Many patients are able to resume desk work and light activities within a day or two after LASIK or SMILE. PRK and LASEK may require a longer recovery—up to a week—before vision is clear enough for some tasks.
Q: Are there options if I’m not a candidate for LASIK?
A: If you have thin corneas, dry eyes, or other contraindications, alternatives such as PRK, LASEK, SMILE, phakic intraocular lenses, or refractive lens exchange may be suitable.
Q: Can myopia surgery correct astigmatism?
A: Yes, most modern laser and lens-based procedures can also correct astigmatism, but suitability depends on the amount and type of astigmatism present.
Q: What are the risks if I have high myopia?
A: Patients with high myopia may have increased risk for certain complications such as retinal detachment, and not all procedures may be suitable. A thorough retinal exam by a specialist is strongly advised before surgery.
