{"slug":"lasik-vs-prk","question":"LASIK vs PRK","answer":"LASIK offers faster visual recovery (1-2 weeks) and less discomfort but requires a corneal flap that carries a small risk of complications; PRK provides better long-term corneal stability and is safer for thin corneas but involves 3-4 weeks of blurred vision and significant post-operative discomfort.","answer_curated":true,"verdict":"Choose LASIK if you have adequate corneal thickness (≥500 microns), value rapid visual recovery, can tolerate minimal post-op discomfort, and don't engage in high-impact contact activities. Choose PRK if you have thinner corneas, participate in combat sports or contact athletics, prioritize corneal safety and stability, and can tolerate several weeks of blurred vision and temporary discomfort during healing.","keyDifferences":[{"label":"Visual Recovery Time","winner":"a","entityAValue":"1-2 weeks","entityBValue":"3-4 weeks"},{"label":"Post-Operative Discomfort Level","winner":"a","entityAValue":"Minimal (mild grittiness)","entityBValue":"Significant (moderate to severe pain for 3-5 days)"},{"label":"Minimum Corneal Thickness Required","winner":"b","entityAValue":"≥500 microns","entityBValue":"≥400 microns"},{"label":"Corneal Flap Complications Risk","winner":"b","entityAValue":"0.5-1% (flap displacement, buttonhole, epithelial ingrowth)","entityBValue":"0% (no flap created)"},{"label":"Long-Term Corneal Haze Risk","winner":"a","entityAValue":"<0.1%","entityBValue":"3-10% (mild to moderate, usually resolves within 12 months)"}],"winner":{"slug":"lasik-laser-assisted-in-situ-keratomileusis","name":"LASIK (Laser-Assisted In Situ Keratomileusis)"},"confidence":"high","entities":[{"name":"LASIK (Laser-Assisted In Situ Keratomileusis)","slug":"lasik-laser-assisted-in-situ-keratomileusis","url":"https://www.aversusb.net/entity/lasik-laser-assisted-in-situ-keratomileusis","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/lasik-laser-assisted-in-situ-keratomileusis"},{"name":"PRK (Photorefractive Keratectomy)","slug":"prk-photorefractive-keratectomy","url":"https://www.aversusb.net/entity/prk-photorefractive-keratectomy","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/prk-photorefractive-keratectomy"}],"faqs":[{"question":"Which procedure is safer long-term?","answer":"Both are safe long-term, but with different risk profiles. LASIK has a 0.5-1% risk of flap-related complications that could require retreatment, while PRK's main long-term concern is corneal haze (3-10% incidence), which is usually mild and resolves within 12 months. LASIK has superior long-term corneal clarity, while PRK maintains better corneal structural integrity. For the average patient, both have excellent safety records with >95% achieving 20/25 vision or better."},{"question":"Can I do LASIK if I have a thin cornea?","answer":"Not reliably. LASIK requires a minimum of 500 microns of corneal thickness to safely create a flap and perform the laser ablation. PRK is specifically designed for thinner corneas and only requires ≥400 microns. If your cornea is between 400-500 microns, PRK is the appropriate choice. Your corneal topography and thickness will be measured during screening to determine eligibility for each procedure."},{"question":"How painful is recovery for each procedure?","answer":"LASIK recovery is minimally uncomfortable—most patients report only mild grittiness or dry eye sensation that resolves within days. PRK is significantly more uncomfortable: patients typically experience moderate to severe eye pain for 3-5 days post-operatively, requiring prescription pain medication and typically requiring 1 week off work. The pain is normal and expected; it reflects the removal of the corneal epithelium and gradually improves as healing progresses. By day 7-10, PRK discomfort becomes manageable without narcotic pain relief."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/lasik-vs-prk","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/lasik-vs-prk), LASIK offers faster visual recovery (1-2 weeks) and less discomfort but requires a corneal flap that carries a small risk of complications; PRK provides better long-term corneal stability and is safer","dateModified":"2026-07-07T18:03:02.072Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/lasik-vs-prk","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/lasik-vs-prk","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/lasik-vs-prk","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/lasik-vs-prk#claimreview","url":"https://www.aversusb.net/compare/lasik-vs-prk","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"LASIK vs PRK","reviewBody":"LASIK offers faster visual recovery (1-2 weeks) and less discomfort but requires a corneal flap that carries a small risk of complications; PRK provides better long-term corneal stability and is safer for thin corneas but involves 3-4 weeks of blurred vision and significant post-operative discomfort.","datePublished":"2026-03-31T22:52:30.526Z","dateModified":"2026-07-07T18:03:02.072Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/lasik-vs-prk","url":"https://www.aversusb.net/compare/lasik-vs-prk","name":"LASIK vs PRK","inLanguage":"en-US"}}}
