anterior segment analyzer

Scansys TA517
Anterior Segment Analyzer
Scansys analyzer provides a professional solution for anterior segment diagnosis. The device applies Scheimpflug camera which can collect 107520/230400 data points and generates 28/60 cornea tomography images in high resolution. Scansys can provide a series of topography maps including cornea curvature maps, cornea thickness maps, cornea elevation maps, etc. It provides good assistance to clinicians in anterior segment diagnosis.

AI Keratoconus Diagnosis
This section introduces AI algorithms to more intelligently determine the possibility of cone disease (KCP).

IOL Optimization
Specially designed for the “IOL Optimization”of refractive cataract surgery. It supports  clinicians in ICL surgery and optimization of Toric IOL, Aspheric IOL and Multifocal IOL for patients.

ICL Surgery Examination
Scansys supports in any Angle to collect a high- definition picture, to provide effective data support for ICL surgery.

Aberration Analysis
The aberrations of the total corneal optical system can be quantified by the Zernike polynomial, used to evaluate the effect of cataract surgery on the visual quality, and guide the personalized refractive surgery. Ensure that the patients can get the best visual quality after surgery.

AI Keratoconus Diagnosis

This anterior segment analyzer, Scansys clinically collects a large amount of data from all over the world and introduces AI algorithms to more intelligently determine the possibility of cone disease (KCP) in the current case.(Reference value:KCP, range 0% -100%)The above figure contains the topographic map of Refractive 4 Maps, and the axial curvature map of the rear surface, and the trend distribution of the thickness map is also given. These are the key references for judging the keratoconus.

IOL Optimization

Specially designed for the “IOL Optimization”of refractive cataract surgery, the anterior segment analyzer is given the K1, K2, Km, and Astig values of the three types of corneal refractive power (Simk, total corneal power, true net refractive power), and Kappa&Alpha angle, respectively. It also provides professional data of the total corneal astigmatism aberration, total corneal spherical aberration and the total corneal irregular astigmatism,and analysis support for solving spherical refractive errors, astigmatism, spherical aberration, and presbyopia in cataract surgery.

Aberration Analysis

This view is a Zernike analysis of the measured corneal front,back and all surface height data, which
calculates a factor for each Zernike polynomial term that describes the contribution of this polynomial
to the height data.To guide the visual quality analysis of refractive surgery.

Lens Fitting Analysis

Based on the topography maps generated by Scansys, the system can recommend several lenses suitable for patient's cornea and simulate the images of patient's wearing lenses with fluorescein observed by slit lamps. This will accelerate the work flow of lens fitting and save the trouble for patient to accept real fluorescein during lens fitting.

Chamber Angle Analysis

Scansys can calculate a chamber angle value based on the tomography images and its exclusive AOD graph gives a trend analysis for the distance between cornea back surface to iris. It also provides cornea volume, anterior chamber volume and anterior chamber depth calculation. These analyses is helpful to glaucoma diagnosis.

Lens Density Analysis

Scansys calculates the lens density value for cross section and longitudinal section which is helpful in cataract diagnosis.
