CT-6 Corneal Topographer

Corneal topography is a computer assisted diagnostic tool that creates a three-dimensional map of the surface curvature of the cornea. The cornea (the front window of the eye) is responsible for about 70 percent of the eye’s focusing power. An eye with normal vision has an evenly rounded cornea, but if the cornea is too flat, too steep, or unevenly curved, less than perfect vision results. The greatest advantage of corneal topography is its ability to detect irregular conditions invisible to most conventional testing.

Corneal topography produces a detailed, visual description of the shape and power of the cornea. This type of analysis provides your doctor with very fine details regarding the condition of the corneal surface. These details are used to diagnose, monitor, and treat various eye conditions. They are also used in fitting contact lenses and for planning surgery, including laser vision correction. For laser vision correction the corneal topography map is used in conjunction with other tests to determine exactly how much corneal tissue will be removed to correct vision and with what ablation pattern.

Corneal topography can be beneficial in the evaluation of certain diseases and injuries of the cornea including:

Corneal diseases

Corneal abrasions

Corneal deformities

Irregular astigmatism following corneal transplants

Postoperative cataract extraction with acquired astigmatism

Gaush CT-6 Corneal topographer is clinically used to diagnose corneal astigmatism, quantitatively analyze corneal shape, and display corneal diopter with data or different colors. It can also display in the mode of axial curvature diagram, refractive diagram, instantaneous curvature diagram and height diagram. This instrument helps to guide the data for corneal contact lens and improve the accuracy of contact lens adaptation.

Gaush CT-6’s Placido cone measurement is the most widely used corneal topographic measurement method. The technology is mature and already widely used in clinical practice.Also with two options of Manual/Auto capture mode, automatic capture mode can meet most demands, and the manual capture mode can meet some exceptional demands.

Besides the general corneal parameters?which?can be inter-converted to meet the form that can read the keratoscope data, CT-6 also provide:

Fourier topographic map

Topographic maps in difference formats

?Axial curvature diagram

Instantaneous curvature diagram

Diopter?(refractive)diagram

Hypsogram(height diagram)
