Bansal Eye Hospital Introduces Silk, Redefines Laser Vision Correction In North India

SILK, the next generation of Laser Vision Correction, is the latest and most advanced Laser Vision Correction launched in Ambala (for the first time in north India Except Delhi NCR) by Bansal Eye Hospital (BEH). Continuing the tradition of launching the latest technology for specs removal in the region, BEH is once again proud to launch the latest technology for the first time in north India Except Delhi NCR (first in Punjab, Haryana, Himachal Pradesh, Uttarakhand, and Rajasthan).

The name of the technology is SILK (Smooth Incision Lenticule Keratomilesis). It is by the world’s leading company in eye care, Johnson’s and Johnson’s Vision USA. Launched in October 2023, this technology is the latest benchmark in the field of refractive surgery and is lauded for its notably quick recovery time. Imagine undergoing eye surgery today and seamlessly transitioning back to your daily life tomorrow.

The SILK procedure is done by the world’s fastest, ultra-precise, low-energy-delivering (60 nanojoules) femtosecond laser. This technology has introduced for the for the first time biconvex lenticule design, bridge[1]free tissue dissection, and 1 micron spot separation, due to which it provides quick recovery, sharper vision, better depth of focus, and minimal dry eyes. Studies conducted on patients who underwent the silk procedure revealed impressive results, with 99% of the patients expressing satisfaction with the outcome, 98% pleased with rapid improvement in their eye vision, and 96% willing to recommend silk to friends and family members. This technology has many advantages over previous technologies like SMILE (launched in 2012) and Contoura Lasik (launched in 2015).

Bansal Eye Hospital has always been one of the pioneer institutes for refractive surgeries in north India Except Delhi NCR. it was one of the first hospital in North India Except Delhi NCR to start the LASIK surgery in north India Except Delhi NCR for specs removal in 1995. It was the first hospital in North India Except Delhi NCR to introduce femtosecond laser surgery in Haryana in 2009. Later, it introduced Design Refractive Studio (HDV2.0) technology in 2019. Now, BEH has introduced SILK (Smooth Incision Lennticule Keratomilesis) in 2023 for the first time in north India Except Delhi NCR.

BEH has a highly experienced team of doctors who have rich experience in the field. The hospital has to its credit more than 50,000 satisfied surgeries, cataract surgeries, and other surgeries. The doctors at BEH have experience from highly reputed institutes like Advance Eye Centre, PGI, Chandigarh, and other reputed institutes for the refractive department.

Dr. Ashish Bansal is one of the most renowned specialists in refractive surgery and cataract and anterior segment surgery. He has been doing high[1]volume refractive surgeries. He did his M.S. from Advanced Eye Centre Chandigarh and a super specialty fellowship in corneal and refractive surgeries.

Differences between different technologies: SILK vs. SMILE

Both are innovative lenticule extraction technologies, but SILK has the advantage of several advancements that enhance its performance over SMILE.

Below are some of the areas in which SILK is significantly different from SMILE –

  • Ultra-Low Energy Laser – SILK operates at a mere 60 nanojoules compared to SMILE’s 150 nanojoules, reducing collateral tissue damage and promoting faster visual recovery.
  • Bridgeless Spot Separation – SILK’s unique separation method results in smoother lenticule dissection, less swelling, and inflammation, enhancing recovery.
  • Biconvex Lenticule Design – This design in SILK im[1]proves vision quality, accelerates nerve regeneration, and reduces dry eye symptoms.
  • Cyclotorsion Compensation – SILK corrects eye rotation changes, a feature that is absent in SMILE, reducing the risk of residual astigmatism.
  •  Visual Axis Treatment – SILK aligns treatment with the visual axis, unlike SMILE’s focus on the pupillary axis, ensuring more natural and effective vision correction.
  • Rapid Recovery Time – SILK patients typically experience a recovery time of just 24 hours, significantly shorter than the one-week period associated with SMILE.

SILK not only surpasses SMILE but has also revolutionized the field with an edge over the traditional LASIK procedure –

  • Flapless Technique – SILK’s approach eliminates the risks associated with LASIK’s corneal flap, making it safer for individuals in contact-intensive activities.
  • Superior Vision Quality – Achieving up to 6/5 vision, SILK surpasses LASIK’s 6/6 standard by focusing on the visual axis.
  • Reduced Dry Eye Incidence – The biconvex lenticule design in SILK is gentler on corneal nerves, leading to a lower incidence of dry eyes post-surgery.
  • Cyclotorsion Compensation – SILK’s inclusion of this feature ensures higher accuracy in cylinder correction.
  • Preserved Depth of Focus – The unique design in SILK maintains depth of focus, ensuring a smooth transition across different focal points.

How does SILK work?


ELITA's advanced laser creates a precise corneal lens without flaps or blades.


The laser carefully removes this lenticule by creating a tiny incision.

Frequently Asked Questions

The SILK Procedure is a cutting-edge refractive laser procedure offered by J&J Vision. It is now the world’s most advanced FLAP-LESS Laser Vision Correction procedure. It is designed to correct myopia (nearsightedness) up to 8D and astigmatism up to 3D, providing patients with improved vision without the need for glasses or contact lenses.

The SILK Procedure uses ultra-precise Femto-laser technology, correcting refractive errors such as myopia and astigmatism. It involves creating a small disc-shaped piece of tissue called a lenticule in the deeper layers of the cornea, which corresponds to the power of the eye, which is then delicately removed, reshaping the cornea to improve vision.

The SILK Procedure is primarily designed to correct myopia (nearsightedness) and astigmatism. It cannot correct hyperopia or “plus” powers.

The SILK Procedure is considered safe and has been developed with a focus on minimizing risks and maximizing patient comfort. However, like any surgical procedure, there may be potential risks and complications, which should be discussed with your ophthalmologist.
