Scansys 3D Anterior Segment Analysis System TA517

Scansys anterior segment 3D analyzer provides a set of professional anterior segment diagnostic solutions for clinics. The product uses Scheimpflug imaging,

A single shot of 1 second generates 28/60 high-definition corneal anterior and posterior tomographic images, and 107520/230400 data points are collected. Through analysis and calculation, a series of corneal topographic maps, corneal thickness maps, and height maps are generated, which are the clinical aspects of the anterior segment. The diagnosis provides strong support.

Keratoconus Analysis

The keratoconus coefficient (KCP) can be used to visually judge the possibility of the disease and assist the doctor in the analysis of the keratoconus.

High-end Intraocular Lens Optimization

A guidance module specially designed for IOL optimization of refractive cataract surgery, instructs doctors to perform pre- and post-operative examinations of high-end intraocular lenses and select Toric, aspheric or multifocal intraocular lenses.

ICL Surgery

It supports shooting a single high-definition Scheimpflug tomographic image at any angle, and measuring arch height, anterior chamber depth and other data can be used for pre- and post-operative inspections of ICL surgery. AI intelligence recommends the diameter of the ICL lens and predicts the postoperative arch height.

Aberration Analysis

Zernike polynomials can be used to quantify the aberration of the total corneal optical system, which can be used to evaluate the impact of cataract surgery on visual quality, and can also be used to guide personalized refractive surgery to ensure the visual quality of patients after surgery.

Product Advantages

✦ Keratoconus analysis

Collect a large amount of data from all over the world, through the corneal surface KCI, AI four-picture cone recognition, SVM classification method, more intelligently and accurately judge the possibility and severity of the current case of keratoconus, the reference value (KCP, range 0%-100 %). The above figure contains four topographic maps of refraction and the axial curvature of the posterior surface of the cornea, as well as the trend distribution of the thickness map. These are the key basis for judging keratoconus.

✦ Optimum intraocular lens

A guide function module specially designed for IOL optimization of refractive cataract surgery, providing k1, k2, km and Astig values, Kappa angle and Alpha angle of three corneal refractive types (Simk, full corneal refractive power, true net refractive power) And other special reference values. At the same time, it provides professional calculation data such as pan-corneal astigmatism, pan-corneal spherical aberration, pan-corneal high-order aberration, and provides professional data and support for solving spherical refractive error, astigmatism, spherical aberration, and presbyopia in cataract surgery.

✦ Aberration analysis

Through Zernike wavefront aberration analysis, it provides the characteristic aberration analysis and diagrams of each order of zernike on the anterior, posterior and pan-corneal cornea, which has guiding significance for the analysis of visual quality before and after refractive surgery.

✦ Simulation try-on of contact lens

In response to the clinical needs of contact lenses, based on the measurement of the patient’s corneal topography, the Scansys system can recommend contact lenses suitable for the patient’s corneal parameters and simulate the fluorescence staining of the cornea under the slit lamp, speeding up the process of orthokeratology lens fitting , Which eliminates the trouble of multiple corneal staining for patients.

✦ ICL surgical examination

Before surgery, it provides rich quantitative data such as anterior chamber depth and corneal diameter. AI intelligently recommends ICL size and predicts postoperative arch height. After the operation, a single high-definition Scheimpflug tomographic image can be taken at any angle to accurately measure the arch height.
