Laser Refractive Cataract Surgery

Introducing Laser Refractive Cataract Surgery for the first time in Tamilnadu & kerala

Why Laser Refractive Cataract Surgery

Cataract surgery is considered to be one of the safest surgical procedures in the world. However, advancements in technology has led to the evolution of Laser Refractive Cataract Surgery which further ensures more absolute precision and accuracy, with better visual outcomes for the patient.

History of Cataract Surgery

During the past 50 years, we saw the following advances in cataract surgery

  • The development of the intraocular lens – a synthetic lens that replaces the opacified natural lens of the eye.
  • Moving from intra-capsular surgery (where the entire lens is removed in toto) to extra-capsular, where the capsule is retained in order to support an intraocular lens. This required a larger incision and hence sutures.
  • Phacoemulsification, which breaks up the hardened natural lens into fragments using ultra sound power and enables their removal through a small incision with implantation of the foldable intraocular lens.

Today, ophthalmologists consider the next advance to be the introduction of the Femtosecond Laser (LENSX) for use in laser refractive cataract surgery.

Femtosecond Laser Refractive Cataract Surgery – the technology


Laser Refractive cataract Surgery – The Technology

LenSxThe Eye Foundation has introduced LenSx® femtosecond laser cataract surgery technology by Alcon for the first time in this region. It was the first femtosecond laser cataract surgery platform to be approved by the FDA and TGA, and the first system released in the US and Australia with proven credentials and accuracy.

Femtosecond Lasers use ultrashort pulses of near infrared laser light to disrupt the tissue. Guided by optical coherence tomography (OCT), the LenSx® platform creates a 3D imaging of the eye. With this information, the surgeon can plan the procedure. Once final checks are made, the laser is started, automating the first four steps of cataract surgery, the whole sequence needing less than 60 seconds.

How is Laser Refractive Cataract Surgery different?


Conventional Vs LENSX

Laser technology replaces the first four essential steps of cataract surgery.

The laser is used to make the corneal incisions. This first step in cataract surgery has, to date, been performed manually using a diamond or a metal blade. Unlike a blade, when using the laser refractive cataract surgery technique, the image guided, computer-controlled laser can be programmed to make a precise cut with a shape not achievable mechanically. The shape, length and width can all be programmed with the laser. This reduces the incidence of variations in the surgical wound that can lead to operative complications. It adds to wound integrity and further improves the visual outcome with reduction of surgically induced astigmatism.

Precise Laser Incisions

Precise Laser Incisions

A laser-cut ‘Capsulorhexis’. The lens of the eye is surrounded by a capsule – the laser creates a perfectly round opening in this capsule allowing access for removal and replacement of the lens. The size and position can be accurately selected, the ideal sized overlap which has been understood to be critical for optimal positioning of the intraocular lens. Performing this delicate, intricate step with laser technology has been shown to provide better visual outcomes.

The high energy of ultrasound, if improperly used, can pose a risk for complications, including tearing the capsular bag and injuring the delicate zonular fibres that hold the bag in place. The integrity of these zonular fibres is crucial for a successful surgical outcome. Laser refractive cataract surgery reduces the risk of damaging either the capsular bag or the zonular fibres, with the laser gently breaking apart the hard lens, image guided with precise placement of the cuts in the cataractous lens. The fragments can then be removed using significantly reduced (by approximately 50%) ultrasonic power which ensures protection for the different components of the eye.

image4Further, arcuate incisions can be fashioned on the cornea with the laser which corrects the astigmatism and further improves the visual outcomes.

Once the laser procedure has been performed, the surgery continues in the operating theatre, where the natural lens, separated into fragments by the laser are removed and the synthetic intraocular lens of precalculated power is inserted into the capsular bag.

The move to constantly enhance surgical performance to the highest levels of precision is a constant endeavour and with this intent, we, at the Eye Foundation, have moved to embrace Lensx Laser Refractive Cataract Surgery.

Mr. Karthik Raja

First of all a big thank you for performing a successful operation. I feel really confident and happy about my vision now. If I knew the world would be so colourful and sharp, I would have undergone this process a long time ago. I never wore glasses either so couldn’t see properly earlier. Thanks again to all involved and keep up the good work.

Feeling really great after the treatment. I was really anxious about the pain during the procedure. But to my surprise I never felt even a slightest prick and should say kudos to the team.
