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."},{"question":"I play contact sports—which should I choose?","answer":"PRK is strongly recommended for contact athletes, boxers, military personnel, and martial artists. LASIK creates a corneal flap that remains a structural weakness for life; even years post-operatively, a direct eye impact could potentially displace the flap. PRK eliminates this risk entirely by not creating a flap. While LASIK patients can safely return to contact sports after 3-4 weeks, the flap vulnerability remains a theoretical concern. For high-impact athletes, PRK's superior structural integrity is the better choice despite longer recovery."},{"question":"Will I need glasses after either procedure?","answer":"Both procedures aim for 20/20 uncorrected vision in approximately 90-95% of patients. However, 5-10% experience slight undercorrection or overcorrection requiring minor glasses for distance or near vision. PRK may have slightly higher retreatment rates (5-10%) due to corneal haze effects on healing, while LASIK typically requires retreatment in 3-5% of cases. Patients over 40 often need reading glasses regardless of the procedure due to natural presbyopia (age-related loss of focusing ability)."}],"relatedComparisons":[{"slug":"yoga-vs-pilates","title":"Yoga vs Pilates","category":"health"},{"slug":"ibuprofen-vs-acetaminophen","title":"Ibuprofen vs Acetaminophen","category":"health"},{"slug":"invisalign-vs-braces","title":"Invisalign vs Traditional Braces","category":"health"},{"slug":"whey-protein-vs-casein-protein","title":"Whey Protein vs Casein Protein","category":"health"},{"slug":"crossfit-vs-gym-training","title":"CrossFit vs Gym Training","category":"health"},{"slug":"therapy-vs-medication","title":"Therapy vs Medication","category":"health"},{"slug":"meditation-vs-yoga","title":"Meditation vs Yoga","category":"health"},{"slug":"contact-lenses-vs-glasses","title":"Contact Lenses vs Glasses","category":"health"},{"slug":"physical-therapy-vs-chiropractic","title":"Physical Therapy vs Chiropractic","category":"health"},{"slug":"cbd-vs-thc","title":"CBD vs THC","category":"health"},{"slug":"treadmill-vs-elliptical","title":"Treadmill vs Elliptical","category":"health"},{"slug":"whole-milk-vs-skim-milk","title":"Whole Milk vs Skim Milk","category":"health"}],"relatedBlogPosts":[{"slug":"keto-vs-carnivore-vs-paleo-which-diet-works-best-in-2026","title":"Keto vs Carnivore vs Paleo: Which Diet Works Best in 2026?","excerpt":"Choosing between keto, carnivore, and paleo diets can be overwhelming.
