SMILE vs PRK – Why SMILE Stands Out as the Best Option vs PRK has become the topic of current discussion. Surgeons and people searching for a safer alternative to Lasik are discussing about the best choice.
SMILE (Small Incision Lenticule Extraction) Vs PRK (Photorefractive Keratectomy) are two good options. They aim to provide freedom from glasses and contact lenses. However, SMILE is quickly becoming the preferred choice for many patients. At Khanna Vision Institute, patient care is a priority. They also prioritize advanced technology. SMILE often stands out as the best option for achieving clear vision safely and efficiently.
This blog will compare SMILE and PRK to explore why SMILE is often the superior choice for vision correction.
1. Procedure Overview – SMILE vs PRK
SMILE
SMILE is a minimally invasive laser vision correction procedure designed to treat myopia (nearsightedness) and mild astigmatism. A femtosecond laser creates a tiny incision (2-4 mm) in the cornea. This incision helps to remove a thin layer of tissue (lenticule). This reshapes the cornea to correct vision while maintaining its structural integrity.
PRK
PRK was one of the earliest laser vision correction procedures. It involves removing the outer layer of the cornea (epithelium) to reshape the underlying corneal tissue with an excimer laser. While effective, the recovery process is longer because the epithelial layer must regenerate.
2. Key Differences Between SMILE vs PRK
Minimally Invasive Nature
- SMILE: The procedure is performed through a small incision without creating a flap or removing the epithelium. This preserves the cornea’s natural structure and minimizes tissue disruption.
- PRK: Requires complete removal of the corneal epithelium, which takes several days to regenerate. This process often leads to discomfort and a longer healing period.
Post-Operative Comfort
- SMILE: Patients experience minimal discomfort after the procedure, with a rapid recovery and little to no pain.
- PRK: Patients may experience significant discomfort for several days due to the removal of the epithelium and its subsequent regeneration.
Recovery Time
- SMILE: Most patients return to normal activities, including work, within 24-48 hours. Vision stabilizes quickly, allowing for a seamless transition back to daily life.
- PRK: Recovery is longer, often taking several weeks for vision to stabilize and for the epithelium to heal fully.
Risk of Complications
- SMILE: The flapless technique reduces the risk of infection, flap dislocation, or dry eye syndrome, making it ideal for individuals with active lifestyles.
- PRK: While effective, PRK is associated with temporary haze, sensitivity, and prolonged healing.
3. Advantages of SMILE Over PRK
Faster Healing
Minimally invasive nature allows for a much quicker healing process compared to SMILE vs PRK. By preserving the corneal epithelium, SMILE eliminates the need for weeks of healing and reduces the risk of long-term sensitivity.
More Comfortable Recovery
With PRK, patients often require bandage contact lenses and pain relief during the recovery phase. SMILE eliminates this discomfort, providing a smooth, pain-free recovery experience.
Lower Risk for Active Lifestyles
SMILE’s flapless approach makes it an excellent choice for athletes or individuals engaged in high-impact activities. The robust post-surgical cornea ensures long-term stability and resilience. In contrast, PRK patients may need to wait longer before returning to strenuous physical activities.
Suitable for a Wider Range of Patients
SMILE is suitable for patients with thinner corneas who may not be eligible for other laser procedures like LASIK. PRK can also work for these patients, but its downsides in recovery and comfort often make SMILE the better alternative.

6. Is PRK Ever the Better Option?
SMILE is often the better choice. However, PRK may still be suitable for patients with certain conditions. These include very thin corneas or irregular corneal shapes. Such conditions make them ineligible for SMILE or LASIK. However, for most patients, SMILE offers a quicker, more comfortable, and less invasive alternative.
7. Conclusion – SMILE vs PRK
When comparing SMILE vs PRK, it’s clear why SMILE has become the preferred option for vision correction. SMILE offers a minimally invasive technique. It ensures rapid recovery and has a low risk of complications. This provides patients with a safe and effective solution for clearer vision.
