Scansys can capture 60 high-definition Scheimpflug images of corneosclera in a single scan, covering a 16mm-diameter of corneoscleral area. It can display the corneoscleral sagittal height in a 360° panoramic view without any multiple scans and image stitching, and provide 13 key parameters so as to offer comprehensive and accurate data support for scleral lens fitting.
Scansys allows eye-care professionals to customize the contact lens database. Combined with the corneal parameters of patients, it can simulate the contact lens fitting effect (3D/2D) under the corneal fluorescence staining with slit lamp. Moreover, an ideal fluorescence fitting simulation effect can be obtained through parameter adjustment. This is helpful for beginners to grow rapidly, improve the fitting efficiency of orthokeratology lenses, and avoid the trouble and discomfort caused to patients by changing trial lenses multiple times.
Scansys has a built-in automatic calculation for contact lens fitting , which can help eye-care professionals quickly obtain the fitting parameters of orthokeratology lenses, soft contact lenses or RGP lenses based on the patients’ corneal parameters.

The various keratoconus related parameters provided by Scansys, such as the Refractive 4 Maps, Keratoconus Index (KCI) of the anterior and posterior corneal surfaces, Keratoconus Probability (KCP) and Keratoconus Grading (Grade 0-IV), etc., can help eye-care professionals analyze keratoconus effectively.
The corneal morphology of normal people's binocular eyes shows a certain degree of symmetry, while patients with keratoconus often have the disease onset in one eye first. Eye-care professionals can use the binocular contrast function of Scansys to compare the morphology and values of the Refractive 4 Maps of the patient's binocular corneas, thereby improving the keratoconus screening efficiency in the early stage, such as forme fruste keratoconus. It is also possible to determine whether keratoconus progresses by comparing the differences of the same eye of the patient at different time points.
By calculating the gray value in both the cross-sectional and longitudinal sections of the crystalline lens, Scansys can assist eye-care professionals better design the cataract surgeries and the intraoperative operations.
Scansys has built-in multiple intraocular lens calculation formulas such as Jin, SRK-T, Holladay 1, Hoffer Q, etc. and the IOL parameters provided by manufacturers. It can quickly provide the corresponding IOL power for common cataract patients or cataract patients after refractive laser surgeries.
(Popular Function)
Scansys provides key parameters such as three types of corneal refractive power (Simk, Total Corneal Power and True Net Power), Total Corneal Astigmatism, Total Corneal Spherical Aberration, Total Corneal Higher-Order Aberration, the ratio of the curvature radius of the posterior corneal surface to that of the anterior corneal surface, Kappa Angle and Alpha Angle. Combined with the built-in calculators for age optimization of astigmatism and age optimization of spherical aberration, it can truly accomplish the optimization of advanced IOLs and help patients achieve the best visual quality after refractive cataract surgery.
Scansys can, based on the analysis of data such as the corneal diameter, corneal curvature, corneal thickness, anterior chamber depth and anterior chamber angle of the patient, recommend the size of the ICL lenses and predict the range of postoperative vault.
Scansys supports capturing high-definition Scheimpflug images at any angle after the ICL surgery to precisely measure the postoperative vault, thereby more objectively evaluating the effect and safety of the surgery.
Scansys provides up to 8-order Zernike wavefront aberration data of the corneal anterior and posterior surfaces and the entire cornea with a maximum diameter of 12mm. Meanwhile, it can also simulate the visual quality image in a more intuitive way through Retinal Imaging, Point Spread Function (PSF) and Modulation Transfer Function (MTF), etc., providing a crucial basis for the preoperative plan design and postoperative visual quality evaluation of refractive cataract surgery and customized corneal refractive surgery.
Scansys can decompose the complex corneal topography data of patients into quantitatively analyzable components such as Spherical Component, Decentration Component, Regular Astigmatism Component and Irregularity Component through Fourier Analysis, which can provide more scientific guidance basis for eye-care professionals to design refractive cataract surgery and personalized corneal refractive surgery plans.
Scansys is capable of providing a comprehensive set of parameters necessary for creating corneal stromal ring tunnels both through manual dissection (utilizing a corneal stromal ring tunnel dissector) and femtosecond laser dissection based on the corneal morphology of patients, in order to improve the predictability of Intrastromal Corneal Ring Segments (ICRS) implantation and reduce surgical complications.
By calculating the gray levels of the anterior chamber and the anterior chamber angle of patients, Scansys can obtain parameters such as Angle Opening Distance (AOD) and Trabecular-Iris Space Area (TISA) and thereby present the distribution trend curve of the original AOD and the linearly fitted distribution trend on both sides of the corneal apex, as well as parameters such as Anterior Chamber Angle, Anterior Chamber Volume, and Anterior Chamber Depth. This is of certain enlightenment significance for the early screening of glaucoma and can also track the effect of laser peripheral iridectomy.
Scansys has 5 built-in IOP correction formulas based on corneal thickness, which help eye-care professionals well understand the real IOP of patients.
Parameters such as corneal volume and anterior chamber volume with the corneal apex and the thinnest point as the origin have been developed according to the scientific research needs of the KOL.
The interface for setting contact lens parameters has been developed to fulfill the user’s need for specific contact lens fitting.
The recommendation module for ICRS implantation has been developed to meet the user’s surgical need.
The IOL calculation formula of Jin was jointly developed with the cataract expert.
The calculation softwares for the age optimization of IOLs developed by cataract expert have been built in.
