Laser-assisted in situ keratomileusis using corneal flap for rapid vision correction.
Working professionals, busy lifestyles, those with adequate corneal thickness, standard refractive errors
Photorefractive keratectomy using surface ablation without corneal flap creation.
Athletes, military personnel, boxers, those with thin corneas, occupations with high-trauma risk
Both procedures achieve over 90% success rates with 20/20 vision or better long-term. LASIK offers faster recovery (24-48 hours) and quicker visual improvement, making it ideal for most patients. PRK is safer for thin corneas and contact sports enthusiasts due to no corneal flap creation.
Choose LASIK if you want rapid recovery, minimal downtime, and have adequate corneal thickness—it's ideal for most working professionals. Choose PRK if you have thin corneas, participate in contact sports, or work in high-trauma environments like military or boxing, as it offers superior structural integrity and long-term safety.

Both are equally safe with modern technology and experienced surgeons. LASIK carries minimal flap-related risks (0.5-1%), while PRK eliminates flap risk entirely. Long-term complications are rare with either procedure. The choice depends on individual anatomy and lifestyle factors.
