LenSx Laser System

Cataract Surgery

Metabolic changes of the crystalline lens fibers in your eye can lead to opacification and loss of transparency of the lens in the eye over time. This could lead to vision impairment. During cataract surgery, the cloudy natural “cataract” lens in your eye is removed and replaced with a synthetic lens to restore clear vision.

Laser Cataract Surgery

Laser cataract surgery was first performed in the USA in 2010. Due to the precision, quick turnaround time, consistency and convenience offered by this procedure, it has gained the support of ophthalmic surgeons worldwide.

Most laser cataract surgeries take just 15 minutes and since the procedure only requires local anesthesia you will be awake during this procedure.

How a laser cataract surgery is performed:

  • The laser-assisted cataract system’s camera analyses your eyes and feeds detailed visuals of your eye lens to a specialized computer. This allows your surgeon to map the eye-lens surfaces and identify the ideal location for incision.
  • A tiny incision in the eye surface is made via laser through which a small probe is inserted. This probe emits ultrasonic sound waves to break up the cataract-damaged lens.
  • The probe is then substituted for another that removes the lens pieces via suction.
  • A new synthetic intraocular lens (IOL) implant is rolled up inside the tip of another probe and inserted through the original incision.
  • The lens is carefully unrolled and positioned for optimal vision.
    Since the incision is tiny, it doesn’t require stitches. After leaving the surgery room you’ll be asked rest in a recovery room for a few hours and then you’ll be discharged. Your eye-doctor will prescribe various eye drops for preventing infection and keeping your eye from getting dry.

LenSx Laser system

In traditional cataract surgery, the surgeon makes an incision in the eye using a blade. However, the LenSx laser system allows ophthalmic surgeons to use a bladeless, computer-controlled refractive cataract laser that uses an image-guided, high-repetition rate femtosecond laser to:

  • Make all required incisions
  • To break the old, cloudy lens and then replaced by a new lens.

This laser system is designed to improve precision during critical steps of cataract surgery that were earlier performed manually. This reduces human errors and increases reliability.

In the hands of an experienced ophthalmic surgeon, the LenSx system makes sure to produce extraordinary, precise and safe results every time.

A few advantages of the LenSx system are:

  • Enhanced procedure automation.
  • Precise and customizable incision architecture.
  • Versatile fragmentation patterns.
  • Simple and efficient one-piece patient interface. This uses an exclusive hydrogel lens technology that
    • Minimizes corneal distortion compared to solid interfaces
    • Reduces intraocular pressure to the cornea compared with solid interfaces
    • Fixates the eye, enhancing control of movement compared to liquid interfaces
  • Innovative, high-definition OCT technology which delivers high-resolution cross-sectional images for every incision.

Complementary Technology

A complementary digital marker can enhance the cataract refractive surgical experience as it automatically positions itself to the streamlined surgical plan. This reduces the time to program LenSx.
