- the value of the total aberration measured by the appliance is stored in a computer from those that have been changed and the flow rate has been added to them. Moreover, the value of the aberrations made by the compensations are calculated by the information transmitted to the computer of the sensors of their use.
- the compensation compensation unit allows for compensation of an output of -15 to +10 degrees.
- the method of stigmatization works in the range from -6 to +6. Compensation for higher abnormalities is a deformable part that can compensate for such aberrations, as well as spherical aberration, and others.
- the expansion of the dynamic range of changes in the sensor of the wavefront is an increase in the relative accuracy of the measurements.

- Compensation is made up of a mobile device located between two lenses. Such a feature allows you to change the distance between the lenses without changing the position of the lenses themselves. For abermetic measurements, these properties are very valuable, since in such a system there is no displacement of the input and output blows.
- the front end of the device increases in comparison with the other, when there is a separate separate plate, which separates the other
- the asymptomatic method should be used in the area of the eye pupil.

- the system for precisely setting the initial angle of the lenses is required. This may be carried out by the use of mechanical, optical, or magnetic sensors.
- the original device must be able to ensure accurate angular lens installation for a good first-time installation, shared by users. For this purpose, for example, stepper motors with a gear or belt (toothed belt), which ensures minimal backlash due to a change in direction, can be used.
- the device can also be equipped with a sensor (optical, magnetic, industrial) of the angle of rotation, when it is necessary to consume mechanical equipment
- the stigma and the compensation of the treatment are located between the patient’s eye and the patient’s test box, which means that the reading is not possible Is ⁇ lzuya as ⁇ igm ⁇ e ⁇ and ⁇ m ⁇ ensa ⁇ ⁇ e ⁇ a ⁇ tsii, m ⁇ zhn ⁇ vnes ⁇ i into radiation ⁇ as ⁇ s ⁇ anyayuschiesya ⁇ ⁇ es ⁇ v ⁇ y ⁇ a ⁇ iny ⁇ az ⁇ vye is ⁇ azheniya ⁇ b ⁇ a ⁇ nye ⁇ zna ⁇ u ⁇ em, ⁇ ye ⁇ n ⁇ ⁇ i ⁇ b ⁇ e ⁇ ae ⁇ in ⁇ iches ⁇ y sis ⁇ eme ⁇ atsien ⁇ a eyes us ⁇ aniv, ⁇ a ⁇ im ⁇ b ⁇ az ⁇ m, i ⁇ influence on ⁇ s ⁇ u z ⁇ eniya.
