Clinical Application
Keratoconus Diagnosis
ECT1 can provide the prevalence of Keratoconus by using the Al algorithm., Further checking the topographic maps to accurately analyze amd diagnose the keratoconus.Refractive Surgery
Total cornea aberration guides surgeons to evaluate preoperative and postoperative visual quality to ensure patients of best surgery effect.IOL Optimization
Specially designed for cataract surgery. It supports clinicians to choose suitable Toric IOL、Aspheric IOL or Multifocal IOL for patients.ICL Surgery Examination
ECT1 supports in different angles to collect a high-resolution picture, It also provides White to White, AC depth for ICL surgery.Functions
AI Keratoconus Diagnosis
ECT1 introduces AI algorithms to more intelligently give the possibility of Keratoconus (KCP)(Reference value:KCP,
range 1% -100%)The above figures contain the topographic maps of Refractive 4 Maps, and the axial curvature map
of the back 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. 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 ECT1, 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
ect1 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.
ICL Surgery Examination
ECT1 supports in any Angle to collect a high- definition picture, to provide effective data support for ICL surgery.
Selectable 4 Maps
Click on the “Selectable 4 Maps” to open a window contains 4 optional color maps. Corneal
thickness and elevation, etc. can be loaded into one of any 4 fields.
With this option, the user can view and print out important topographic maps needed for daily work in one
interface.
Form Factor
The chart upper depicts the corneal form factor and the curvature of the anterior and posterior surface of the cornea at the intersection of the radial axis and the four radial directions. Corneal shape factors include Ecc, E, Q, and P, which can be changed in the “Map and Data Settings” -> “Form Factor Presentation” in the menu bar “Settings” options.
Lens Analysis
ECT1 calculates the lens density value for cross section and longitudinal section which is helpful in cataract
diagnosis.
Refractive Power
In the key parameter column on the right, we give K1, K2, Km, Astig. These values are obtained in the
range of 3mm in diameter of the membrane. In order to describe in more detail the difference of these
values in each diameter range, We give K1, K2, Km, Astig of the axial curvature of the anterior and
posterior corneal, anterior surface refractive power, true net refractive power, full corneal refractive
power topographic map, the distribution table of various areas from 2mm to 9mm in diameter, and the
distribution curve .The changes of these values in different topographic maps and different diameter
ranges are described more intuitively and in detail.
