SILK vs Contoura Vision

When it comes to modern refractive surgery options, SILK and Contoura Vision stand out as two of the most advanced choices available as of 2023-2024. Both procedures offer unique advantages, and the choice between them often depends on the specific needs and conditions of the patient. Here, we delve into the key differences and features of each, helping you understand which might be the best fit for your vision correction needs.

SILK: The Flapless Pioneer


Developed by Johnson & Johnson, SILK represents a significant leap in refractive surgery technology. Its flapless nature is a major advantage, offering a safer procedure and quicker recovery compared to traditional methods. Here are some of its standout features:


  1. Flapless Procedure: Unlike Contoura Vision, SILK does not involve creating a corneal flap. This reduces the risk of flap-related complications, making it a safer option.

  2. Rapid Recovery: Patients undergoing SILK can typically resume normal activities within 24 hours. This quick recovery is a significant benefit for those who cannot afford extended downtime.

  3. Superior Vision Quality: SILK often achieves 6/5 supervision, providing patients with exceptionally sharp vision.

  4. Reduced Dry Eye Symptoms: The procedure is gentler on the eyes, causing less nerve damage and consequently, lower incidence and duration of dry eyes.

  5. Visual Axis Treatment and Cyclotorsion Compensation: SILK aligns its treatment with the visual axis and compensates for cyclotorsion, ensuring a more natural and effective vision correction.

  6. Range of Correction: SILK is effective for correcting myopia up to -8D and astigmatism up to -3D. However, it does not correct hyperopia.

  7. Suitability for Active Lifestyles: Due to its flapless nature, SILK is often preferred by individuals engaged in physically demanding activities and sports. Activities such as gymming, jogging, running, swimming, and sports like cricket, football, and adventure sports can be resumed just 7 days after the procedure.


Contoura Vision: Tailored for Specific Needs in patients with higher corneal irregularities or HOAs

Contoura Vision, while similar in its goal of vision correction, has its own set of advantages, particularly for certain patient profiles:


  1. Flap-Based Procedure: Contoura Vision involves creating a corneal flap, which requires more time to heal compared to SILK's flapless technique.

  2. Correction of Corneal Irregularities: This procedure excels in correcting corneal irregularities and higher-order aberrations, making it a preferred choice for patients with these specific issues.

  3. Range of Correction: Contoura Vision can correct both myopic and hyperopic powers. For myopia, it corrects up to -8D and astigmatism up to -3D, while for hyperopia, it can correct up to +5D.

  4. Post-Procedure Recovery: The recovery time for Contoura Vision is slightly longer, with patients advised to avoid strenuous activities for about a month.

  5. Dry Eye Considerations: Patients undergoing Contoura Vision may experience dry eyes for a longer period compared to those opting for SILK.

  6. Suitability: Contoura Vision is often chosen by medical and government service aspirants or patients with specific eye conditions like higher-order aberrations.




Both SILK and Contoura Vision offer state-of-the-art solutions for refractive errors, with each having its unique strengths. SILK stands out for its rapid recovery, safety due to its flapless nature, and suitability for active individuals. Contoura Vision, on the other hand, is more tailored for those with specific corneal conditions and higher-order aberrations. Patients considering vision correction should consult with an eye care professional to determine the most suitable option based on their individual vision needs and lifestyle.
