What Is the Difference Between Smile Pro and Silk Eye Surgery?

Comparing Smile Pro and Silk Eye Surgery: Key Differences Explained

Explore the key differences between Smile Pro and Silk Eye Surgery, helping you make an informed decision for your eye health.
Smile Pro and Silk Eye Surgery are two prominent, cutting-edge procedures in ophthalmology. Smile Pro surgery, or Small Incision Lenticule Extraction, is a minimally invasive procedure that uses a femtosecond laser to correct myopia (nearsightedness) and astigmatism. It has the advantage of preserving the strength of the cornea and reducing the risk of dry eyes.

On the other hand, Silk Eye Surgery is a novel method that uses silk fibroin – a protein extracted from the silk of the Bombyx mori silkworm – to treat conditions like keratoconus and corneal melting. This technique is heralded for its bio-compatibility and capacity to promote tissue regeneration. These procedures have revolutionized eye care, offering new hope to those battling various eye conditions.


What is the difference between Smile Pro and Silk Eye Surgery?

Smile Pro and Silk Eye Surgery are both laser eye surgery procedures that can correct various vision problems, including nearsightedness, farsightedness, and astigmatism. However, there are some key differences between the two procedures.


Smile Pro
Smile Pro is a femtosecond laser-assisted in situ keratomileusis (FS-LASIK) procedure. It uses a femtosecond laser to create a small flap in the cornea and then reshape the underlying corneal tissue. The flap is then replaced, and seals itself shut.


Silk Eye Surgery
Silk Eye Surgery is a femtosecond laser-assisted lenticular extraction (FS-LASEK) procedure. It uses a femtosecond laser to create a small, lenticular-shaped flap in the cornea. The flap is then lifted back, and the underlying corneal tissue is reshaped. The flap is then replaced and smoothed out.


Key differences between Smile Pro and Silk Eye Surgery


Flap creation:
Smile Pro creates a thinner flap than Silk Eye Surgery. This allows for a quicker and more comfortable recovery process.


Corneal tissue removal:
In Smile Pro, the laser removes a small disc-shaped piece of corneal tissue, whereas in Silk Eye Surgery, the laser only reshapes the underlying cornea without removing any tissue.


Silk fibroin used in Silk Eye Surgery is a natural protein that is highly biocompatible with human tissue. This reduces the risk of complications and promotes faster healing.


Recovery time:
Due to the minimal corneal tissue removal, Silk Eye Surgery patients may experience a shorter recovery time than Smile Pro


Treatment options:
Smile Pro is primarily used for correcting myopia and astigmatism, whereas Silk Eye Surgery can also treat conditions like keratoconus and corneal melting.


Risk of dry eyes:
Smile Pro has a lower risk of causing dry eyes due to its minimal impact on the cornea than traditional LASIK procedures. Silk Eye Surgery is also known for its low risk of dry eyes due to the biocompatible nature of silk fibroin.


Smile Pro is generally more expensive than Silk Eye Surgery due to its advanced technology and lower risk of complications.


Flap replacement:
Smile Pro does not require sutures to replace the flap, while Silk Eye Surgery may require one or two sutures. This can increase the risk of flap dislocation in Silk Eye Surgery patients.


Recovery time:
Smile Pro typically recovers faster than Silk Eye Surgery. However, both procedures have relatively shorter recovery times than traditional LASIK surgeries.


Patient candidacy:
The eligibility for each procedure may vary depending on the patient’s eye health and condition. It is important to consult with a qualified ophthalmologist to determine which procedure is best suited for your needs.


Candidate Eligibility


Who is a good candidate for Smile Pro?

Ideal candidates for Smile Pro are individuals who suffer from myopia or astigmatism. The procedure suits those who want a minimally invasive laser correction procedure, reducing the risk of eye dryness post-surgery. It is also suitable for individuals who prefer a faster recovery period. However, it’s pertinent to note that individuals should have a stable prescription for at least a year before the surgery and be at least 18 years old. Those with certain corneal or retinal diseases, diabetes, or pregnancy may not be ideal candidates and should consult their ophthalmologist.


Who is a good candidate for Silk Eye Surgery?

Silk Eye Surgery is ideal for individuals suffering from keratoconus, corneal melting, and other severe eye conditions. Its unique use of silk fibroin makes it a fitting choice for those seeking a bio-compatible solution with a lower risk of complications. It is also suited for individuals whose corneas may be too thin for other types of laser eye surgery. As with Smile Pro, the patient’s prescription should be stable for at least a year, and they should be at least 18 years old. Those with certain medical conditions or who are pregnant, may not be ideal candidates. Always consult an ophthalmologist to determine the best procedure for your unique needs.



It’s important to note that neither Smile Pro nor Silk Eye Surgery can be declared ‘better’ than the other. The suitability of each procedure largely depends on the patient’s specific condition and individual requirements. Both procedures have their distinct advantages and potential drawbacks. For instance, Smile Pro is notable for its minimal invasiveness and reduced risk of dry eyes, making it an excellent choice for patients with myopia and astigmatism. It also boasts a faster recovery time, which can be a significant advantage for many patients. However, Smile Pro is generally more expensive.

On the other hand, Silk Eye Surgery stands out for its use of silk fibroin, a biocompatible material that promotes tissue regeneration. This makes it a promising treatment for conditions like keratoconus and corneal melting. Despite potentially requiring sutures and having a slightly longer recovery time, it’s typically more affordable. Ultimately, the decision between Smile Pro and Silk Eye Surgery should be made in consultation with an experienced ophthalmologist who can guide an individual’s eye health and personal needs.
