The Orbscan Topographer: What it is and Does

As well as having a cool sounding name, the Orbscan IIZ Topographer is a cutting edge eye mapping instrument. It allows talented eye surgeons to carry out complex eye procedures. A key aspect of any eye procedure is to be able to map parts of the eye on computer. The Orbscan Topographer provides the most highly detailed cornea eye map in the business.

What sets the Orbscan Apart?

The Orbscan scans our corneas. Whereas most cornea scanners in eye surgery only map the front of a cornea the Orbscan maps the whole thing. This provides a multidimensional diagnostic scan. This has proven to have a number of applications in diagnosing eye conditions and subsequent procedures including:

Eye surgery suitability: Enables eye surgeons to determine whether an eye can be operated on. The cornea scans form part of subsequent treatment plans. Post op scans are used to measure the success of operations.

Contact lens fitting: Cornea thinning, Keratoconus, and pre – Keratoconus are now diagnosable through using the Orbscan IIZ.
The future: The Orbscan is playing an integral part in explaining the reasons behind eye conditions including decreased visual acuity and corneal degradation.

How the Orbscan Topographer Works

Eye mapping works by shining light waves into an eye. These light waves are interpreted by computer software to provide a map of our eyes. Corneal mapping is a specialised subset of eye mapping. To be of use, a cornea scanner has to be able to show curvature and thickness of a person’s cornea, as well as surface rises and dips.
The Orbscan has the capability to record 9000 data points of a cornea. Each data point is 1 micron. To give you an idea of how small a micron is, it is 1/1000th of a millimetre. Given that most corneas have a surface area of 11mm, the Orbscan provides a highly accurate map for surgeons. It scans the front, back, thickness, and surface area of a cornea. It is the only cornea scanner able to do this. It takes a mere 1.5 seconds to scan one eye.

Why is Scanning the Cornea Important?

It is essential that the cornea is scanned before and after surgery. Accurate scans of this part of the eye will tell surgeons whether your eye is fit for treatment. Together with other forms of eye mapping it will help your surgical team devise bespoke treatments to treat eye conditions you may have. After surgery it is used to measure success of procedures you may have undergone. Its importance cannot be overstated.

The History of the Orbscan IIz

The Orbscan IIz was developed by a company called Bausch and Lomb. They were one of the first to develop Iris recognition and mapping in 2004. This breakthrough paved the way to develop all kinds of eye mapping technology. These breakthroughs have greatly increased the success rates of eye surgery throughout the world.
