Bochner Eye Institute Offering Laser Cataract Surgery in Toronto

Wednesday, September 12th, 2012

The most significant advance in cataract surgery in the past 50 years has been the development of laser cataract surgery. We are proud to be the first centre in Canada to offer laser cataract surgery with the CatalysTM precision laser system. Laser cataract surgery automates many of the steps that were previously performed manually with a forceps, needle, or blade. The precision of the laser allows for enhanced safety and outcomes.

Bladeless Laser Cataract Surgery has a number of unique advantages over traditional cataract Surgery:

  1. Better self-sealing incisions with less chance of leakage.
    The laser precisely creates all the necessary incisions in the cornea. Unlike with a hand-held blade used in traditional surgery, the laser incisions have a unique architecture and a more precise width that allow them to seal better.Masket S, Saraba M. Femtosecond laser-assisted cataract incisions: architectural stability and reproducibility. J Cat & Refract Surg 2010:36:1048-1051
  2. Improved reduction of astigmatism and enhanced comfort.
    The laser incisions to reduce astigmatism are created at a precise location, length, depth, and angle based on intraoperative imaging using an OCT (optical coherence tomography). An OCT provides higher resolution than an MRI. The incisions are created below the corneal epithelium, which provides enhanced comfort. Limbal relaxing incisions with traditional surgery are performed with a hand-held blade.Kymionis G, Yoo S, Ide T, Culbertson W, Femtosecond-assisted astigmatic keratotomy J Cat & Refract Surg. 2010:35(1):11-13
  3. Potential for better refractive outcome and quality of vision
    The laser can create a perfectly round central opening in the anterior capsule of a specific size. The capsule opening can be centered over the visual axis. The intraocular lens is held in place with the remaining capsule. With a more precise capsule opening there is less chance that the intraocular implant will vault forward, backward, or be tilted. This has been shown to result in better quality of vision with a reduction in higher-order aberrations.Kranitz, K; Takacs, A ; Femtosecond Laser Capsulotomy and Manual Capsulorrhexis and Effects on Intraocular Lens Centration. J Refract Surg. 2011;27(8):558-563.
  4. Potential for clearer vision early postoperatively.

    The laser is used to fragment or break the cataract into small segments before being liquefied with ultrasound and removed with aspiration. The laser fragmentation results in a dramatic reduction in ultrasound energy by approximately 96%. This reduced energy is safer for the long-term health of the corneal endothelial cells and may lead to clearer vision in the early postoperative period.Naranjo-Tackman R. How a femtosceond laser increases safety and precision in cataract surgery. Curr Opin Ophthalmol 2010

Laser cataract surgery is a revolutionary cataracts treatment that is safe and precise. The advent of this technology has made it possible for more patients to seek treatment and obtain clear vision, including patients with astigmatism.
