If you wear glasses or contact lenses, you have probably wondered at some point whether surgery could permanently change that. The answer for most people is yes — and the range of procedures now available means that the vast majority of patients with common refractive errors are candidates for at least one option.
This guide maps the full landscape of vision correction surgery available to patients in 2026. It is the starting point for exploring your options in greater depth across the Vision Correction Procedures Compared hub, which covers every procedure reviewed here in clinical detail, with comparison pages, cost breakdowns, and surgeon recognition resources.
What Vision Correction Surgery Does
All vision correction surgeries address the same fundamental problem: your eye does not focus light precisely on the retina. This imprecision produces blurred vision at one or more distances.
The imprecision originates from one of three sources:
- Myopia (nearsightedness): The cornea or eye is too curved or too long, focusing light in front of the retina. Distant objects appear blurred.
- Hyperopia (farsightedness): The cornea is too flat or the eye is too short, focusing light behind the retina. Near objects — and sometimes distant objects — appear blurred.
- Astigmatism: The cornea or lens has an irregular shape, causing light to focus at multiple points rather than one. Vision is blurred or distorted at all distances.
Presbyopia — age-related loss of near focus — is caused by the stiffening of the crystalline lens rather than corneal shape, and requires different treatment strategies.
Vision correction surgeries either reshape the cornea (so it focuses light correctly), implant a corrective lens inside the eye, or replace the natural lens entirely. The right approach depends on which error you have, how severe it is, and the anatomical characteristics of your specific eyes.
Category 1: Corneal Refractive Surgery
Corneal refractive surgery uses a laser to reshape the surface of the cornea — changing its curvature to alter how it bends incoming light. These procedures are the most widely performed vision correction surgeries worldwide.
LASIK (Laser-Assisted In Situ Keratomileusis)
LASIK is the most performed elective eye surgery in the world. More than 30 million procedures have been performed globally, and US annual volumes exceed 700,000. Its enduring popularity reflects a combination of proven long-term safety, excellent outcomes, and the fastest recovery of any major vision correction procedure.
How it works: A femtosecond laser creates a thin, hinged flap in the corneal tissue. The surgeon lifts the flap and applies an excimer laser to reshape the underlying stroma. The flap is then repositioned, where it bonds naturally without sutures within minutes.
Candidacy: Adults 18 and older with stable prescriptions. Adequate corneal thickness is essential — typically a minimum of 480–500 microns. Treatable range: myopia up to -12.00D, hyperopia up to +6.00D, astigmatism up to -5.00D (surgeon and platform-specific).
Recovery: Most patients achieve 20/20 or better within 24 to 48 hours. Return to office work is typically possible the following day.
Limitations: Not suitable for thin corneas, chronically dry eyes, or patients with occupations that put the corneal flap at risk of dislodgement.
PRK (Photorefractive Keratectomy)
PRK predates LASIK and remains the preferred laser procedure for patients who are not LASIK candidates. Rather than creating a flap, the surgeon removes the corneal epithelium (surface layer), applies the excimer laser directly to the stroma, and places a bandage contact lens while the epithelium regenerates.
How it works: The epithelial surface is removed via alcohol solution, a brush, or a laser. An excimer laser reshapes the corneal stroma to the calculated correction. A bandage lens protects the surface during healing.
Candidacy: The same prescription ranges as LASIK. PRK is preferred when corneal thickness is marginal for LASIK, when the patient participates in contact sports, or when corneal surface anatomy makes flap creation inadvisable.
Recovery: Functional vision typically returns within one to two weeks. Optimal visual acuity may take six to eight weeks.
Advantages over LASIK: No flap complications, better biomechanical stability, lower dry-eye incidence, equivalent long-term outcomes.
SMILE (Small Incision Lenticule Extraction)
SMILE represents the most recent major advance in corneal laser surgery. Using only a femtosecond laser — no excimer laser required — the surgeon creates a precise lens-shaped piece of corneal tissue (a lenticule) that is extracted through a small 2–4mm arc incision.
How it works: The VISUMAX femtosecond laser creates the lenticule and a small surface incision simultaneously. The surgeon manually dissects and extracts the lenticule through the incision. No flap is created.
Candidacy: FDA-approved for myopia up to -10.00D with up to -3.00D astigmatism. Not currently approved for hyperopia. Best suited for patients within this range who want flapless surgery with reduced dry-eye risk.
Recovery: Similar to LASIK — functional vision within one to two days. Less dry eye compared to LASIK due to preservation of more corneal nerve tissue.
Limitations: Narrower treatment range than LASIK or PRK. Cannot treat hyperopia. Slightly longer intraoperative time.
Category 2: Phakic Intraocular Lens Implantation
Phakic IOL surgery places a corrective lens inside the eye between the cornea and the natural crystalline lens, without removing the natural lens. This approach preserves the cornea and the eye’s natural focusing mechanism (accommodation).
EVO ICL (Implantable Collamer Lens)
The EVO ICL is the most widely used and clinically validated phakic IOL in the world. Made from Collamer — a proprietary biocompatible material derived from collagen — the EVO ICL is implanted through a 2.8–3.0mm self-sealing micro-incision and unfolds into position behind the iris.
How it works: Two small peripheral iridotomies (or the lens’s built-in central port in the EVO+ design) allow fluid circulation. The lens is folded, inserted through the micro-incision, and positioned in the ciliary sulcus behind the iris. Sutures are not required. The procedure takes 15–20 minutes per eye.
Candidacy: Myopia -3.00D to -20.00D, astigmatism up to -6.00D (toric EVO ICL). Patients must have adequate anterior chamber depth (typically 3.0mm or more). Age 21–45 in most protocols, though ranges vary by surgeon and clinical context.
Recovery: Most patients notice significant improvement within 24 hours. Full stability within one month.
Advantages: Treats prescriptions beyond the laser surgery range. Fully reversible. Preserves corneal integrity entirely. Many patients report exceptional optical quality, particularly in low-light conditions. Excellent for patients with chronic dry eye. Explore our EVO ICL Awards to find recognized specialists.
Category 3: Lens-Based Refractive Surgery
Lens-based procedures replace or supplement the eye’s natural crystalline lens with a precisely calculated intraocular lens. These approaches are typically preferred for patients over 45, those with high prescriptions, or those seeking comprehensive presbyopia correction.
Refractive Lens Exchange (RLE)
RLE is elective lens extraction — the same procedure as modern cataract surgery, performed before cataracts develop. The natural lens is removed using ultrasound phacoemulsification and replaced with a premium IOL calculated to correct the patient’s refractive error.
How it works: The surgeon makes a 2–3mm incision, uses ultrasound energy to emulsify and remove the natural lens, and implants a folded IOL through the same incision. The IOL unfolds and is positioned in the lens capsule without sutures.
IOL Options: Monofocal (single focal point), toric (astigmatism correction), multifocal, trifocal (PanOptix), or extended-depth-of-focus (Tecnis Symfony, Vivity).
Candidacy: Best suited for patients over 45 with presbyopia, high hyperopia or myopia beyond laser range, thin corneas, or those who want to eliminate future cataract risk.
Recovery: Functional distance vision returns within one to three days. Neuroadaptation to premium IOLs may take two to four months.
Considerations: Permanent loss of accommodation. Premium IOL dysphotopsias (halos, starbursts) in a minority of patients. Read more at Refractive Lens Exchange: Vision Correction for Older Adults.

Not all vision correction surgery is equal. The same procedure performed by surgeons of different skill levels, using different technology platforms, in different levels of institutional setting, produces measurably different outcomes.
