Comparison Between Lasik SMILE & SILK Eye Surgery

Eyes are highly sensitive and open, prone to itchiness, dryness, vision related strain, and other types of discomfort. Over the past few years, many people have struggled with eyesight issues, but, they end up using spectacles than finding the permanent solution. Be it due to limited knowledge or no access to the high-end medical services, the vision correction treatment has not helped many individuals. However, laser-assisted eye surgery is one of the sure-shot solutions for treating refractive issues. In the current era of technologically advanced medical infrastructure, laser-assisted eye surgery options have revolutionized the approach towards permanent vision correction. Some of these treatments include Lasik, SMILE and SILK eye surgery. If you want to enquire about SILK eye surgery cost or price estimate of the other laser eye surgery options, then, the following should be assessed.

Vision correction surgeries have revolutionized the treatment of refractive errors such as myopia, hyperopia, and astigmatism. Three of the most popular procedures are LASIK, SMILE, and the newer SILK (Subepithelial Intralase Keratomileusis). Each option offers distinct advantages and potential drawbacks. Knowing these differences is essential for making an informed choice.

1. LASIK (Laser-Assisted in Situ Keratomileusis)

LASIK is one of the most well-established procedures for vision correction. It involves creating a thin corneal flap, then using an excimer laser to reshape the underlying tissue. This reshaping helps light focus correctly on the retina, resulting in clearer vision. After the cornea is reshaped, the flap is carefully placed back into position.

Advantages:

• Proven Success: LASIK has been widely performed for over 25 years, with high patient satisfaction rates.
• Quick Recovery: Patients often experience improved vision within 24 to 48 hours with minimal discomfort.
• Versatile Correction: LASIK can effectively treat myopia, hyperopia, and astigmatism.

Limitations:

• Dry Eye: Temporary dry eye is a common side effect due to the disruption of corneal nerves.
• Flap Risks: The creation of a corneal flap introduces the possibility of complications, such as infection or displacement.
• Not Ideal for Thin Corneas: LASIK may not be suitable for patients with thinner corneas due to the risk of corneal weakening.

2. SMILE (Small Incision Lenticule Extraction)

SMILE is a more recent, minimally invasive laser eye surgery designed to treat myopia and mild astigmatism. It utilizes a femtosecond laser to create a small lenticule (a disc-shaped tissue) within the cornea, which is removed through a tiny incision. This reshapes the cornea, improving vision without the need to create a flap.

Advantages:

• No Flap: SMILE eliminates the risk of flap-related complications since no corneal flap is created.
• Reduced Dry Eye: SMILE may cause less disruption to corneal nerves, reducing the risk of dry eye.
• Minimally Invasive: With a smaller incision, the procedure is less invasive, which may lead to faster healing.

Limitations:

• Limited Correction Range: SMILE is currently approved mainly for myopia and mild astigmatism, excluding those with hyperopia or severe astigmatism.
• Longer Visual Recovery: Vision may take slightly longer to stabilize after SMILE compared to LASIK.
• Fewer Surgeons: SMILE is a newer technology, so fewer clinics and surgeons offer it compared to LASIK.

3. SILK eye surgery cost (Subepithelial Intralase Keratomileusis)

Overview:

SILK is a new procedure that blends aspects of PRK and LASIK. Instead of creating a corneal flap, it uses a laser to remove the epithelium, the outermost layer of the cornea. The underlying cornea is then reshaped, making SILK a suitable choice for individuals with thinner corneas.

Advantages:

• Flapless Surgery: Like SMILE, SILK avoids flap-related risks by not creating one.
• Good for Thin Corneas: Patients with thinner corneas may benefit from SILK as it removes only the epithelium.
• Lower Dry Eye Risk: Since it avoids significant disruption to corneal nerves, it may reduce the incidence of dry eye.

Limitations:

• Longer Healing: Recovery takes longer because the epithelium needs to regenerate, usually taking several days.
• More Discomfort: Patients may experience discomfort as the outer layer of the cornea heals.
• Newer Procedure: SILK is relatively new, so long-term data on its safety and effectiveness are still being collected.

Conclusion

LASIK, SMILE, and SILK are all highly effective vision correction procedures, each offering unique advantages. While LASIK is the most well-known, SMILE and SILK present options for those looking to avoid flap-related complications or reduce the risk of dry eye. The best choice depends on factors like individual eye health, type of refractive error, and personal preferences, so consulting with an experienced ophthalmologist is crucial for making an informed decision.
