Comparing SILK, SMILE & LASIK Eye Surgeries: Which one is Better & Safer?

silk vs smile vs lasik

Thinking about saying goodbye to your glasses or contacts for good? You’re in luck because eye surgery has come a long way, thanks to some amazing technology. In this blog, we’re going to talk about SILK vs SMILE vs LASIK – three big names in the world of eye surgery. Each one has its features and benefits, but SILK eye surgery is grabbing a lot of attention lately for its awesome results.

We’ll dive into what makes each surgery different, how they work, and why SILK might just be the new top choice for clear vision. Whether you’re just curious or thinking seriously about surgery, we’re here to help you figure out which option might be the best for your eyes. Let’s get started and clear things up!

Key Difference Between SILK, SMILE & LASIK

Key Difference Between SILK, SMILE & LASIKWhile each procedure has its own benefits, SILK eye surgery stands out in several critical areas, making it an increasingly popular choice for those seeking vision correction. Here’s why SILK might just edge out the competition:

  • One of SILK’s standout features is its exceptional safety profile. By avoiding the creation of a large corneal flap—a step required in LASIK—SILK reduces the risk of complications related to flap issues. This aspect alone makes SILK a highly attractive option for patients and surgeons alike.
  • SILK delivers superior visual outcomes thanks to its advanced laser technology and precision. Patients who choose SILK often report achieving a higher quality of vision, with many reaching 20/20 vision or better. This improvement is not only about seeing clearly but also about how quickly and accurately patients can focus, offering a noticeable enhancement in their overall visual experience.
  • One of the most appealing aspects of SILK surgery is the rapid recovery time. Patients can expect to see significant improvements in their vision within just 24 hours post-surgery, allowing for a quick return to daily activities without the lengthy downtime associated with other procedures. This fast recovery is due to the minimally invasive nature of SILK, which promotes quicker healing and reduces the discomfort often experienced during the recovery phase.

In comparison to SMILE and LASIK, SILK stands out for offering a combination of high safety, exceptional visual outcomes, and speedy recovery. While SMILE and LASIK have been revolutionary in their own right, SILK’s advancements in technology and technique make it a compelling choice for those seeking the latest in vision correction.

Comparing Procedures: SILK vs. SMILE vs. LASIK

When it comes down to choosing an eye surgery, understanding how each procedure works can greatly influence your decision. Here’s a brief comparison of the surgical techniques and lenticule designs involved in SILK, SMILE, and LASIK, highlighting the distinct approach each one takes:


  • SILK: Flapless and less invasive, SILK surgery focuses on minimizing tissue disruption. This approach promotes faster healing and reduces potential complications.
  • SMILE: Also flapless, SMILE involves the extraction of a pre-shaped lenticule from within the cornea to correct vision. This method is known for being minimally invasive.
  • LASIK: This procedure involves creating a corneal flap to reshape the underlying corneal tissue. It’s a more invasive approach compared to SILK and SMILE but is well-established and effective for a broad range of vision corrections.

Lenticule Design:

  • SILK: Uses a biconvex lenticule design, which is tailored to enhance vision quality while reducing the risk of dry eyes post-surgery. This design aims to mimic the eye’s natural shape more closely.
  • SMILE: The lenticule in SMILE surgery has a flat configuration. While effective for vision correction, this design doesn’t specifically address post-operative dry eyes as SILK does.
  • LASIK: Not applicable, as LASIK does not involve lenticule extraction. Instead, it reshapes the cornea directly using a laser.

These comparisons show the unique aspects of SILK, SMILE, and LASIK surgeries. SILK’s approach, with its flapless technique and biconvex lenticule design, offers an innovative and less invasive option for patients seeking effective vision correction with quick recovery and minimal side effects.

Cost Comparison: LASIK vs. SMILE vs. SILK

When considering eye surgery, understanding the costs involved is crucial. Here’s a look at how LASIK, SMILE, and SILK surgeries compare in terms of expenses in Indian Rupees:

  • LASIK: This well-established option tends to be more budget-friendly, with the cost hovering around INR 12,000 per eye.
  • SMILE: As a newer, minimally invasive technique, SMILE surgery comes with a higher cost, reflecting its advanced technology and the precise corrections it offers. Patients can expect to pay approximately INR 65,000 per eye for SMILE surgery, a price that includes the benefits of a flapless procedure and a quick recovery.
  • SILK: The latest innovation in refractive surgery, SILK, is at the premium end of the cost spectrum, priced up to INR 60,000 per eye. The cost is indicative of the cutting-edge laser technology used, the non-invasive nature of the procedure, and the superior visual outcomes it promises.

While SILK and SMILE have similar price points, distinguishing between them—and LASIK—goes beyond cost alone. Considerations should include your specific vision needs, the potential for risks and complications, the recovery process, and the expected quality of vision post-surgery.

Although LASIK might be lighter on the wallet, the advancements offered by SMILE and especially SILK could represent a worthwhile investment for those prioritizing the latest in eye surgery technology and the promise of minimal discomfort and quick recovery.

Eligibility Criteria

When considering vision correction surgeries like SILK, SMILE, and LASIK, understanding who is eligible for each procedure is crucial. Each method has specific criteria based on the type of refractive errors it can correct, as well as other factors like age and eye health. Here’s a breakdown of eligibility for these three advanced procedures:

  • LASIK: Known for its versatility, LASIK can correct a wide range of refractive errors, including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It’s suitable for adults who have stable vision prescriptions, typically those over 18 years old. LASIK is often recommended for individuals with up to -12D of myopia, up to +6D of hyperopia, and astigmatism up to -6D, though these ranges can vary based on individual assessments.
  • SMILE: This procedure is primarily focused on treating nearsightedness and certain degrees of astigmatism. SMILE cannot correct farsightedness, making it less versatile than LASIK in the range of refractive errors it addresses. Candidates for SMILE are usually over 18, with stable vision prescriptions, having up to -10D of myopia and astigmatism up to -3D.
  • SILK: The newest addition to refractive surgery options, SILK, is suitable for a broad spectrum of refractive errors, similar to LASIK. It can correct nearsightedness up to -8D and astigmatism up to -3D. However, like SMILE, SILK does not correct hyperopia. SILK’s eligibility criteria also include being over the age of 18 with a stable prescription. Its cutting-edge technology and less invasive nature make it a promising option for many patients seeking flexibility in correcting vision issues.

Factors such as corneal thickness, overall eye health, and the presence of other eye conditions will also play a crucial role in determining your eligibility for SILK, SMILE, or LASIK surgery.
