Autorefractometer

Automatic refraction measurement is performed with a precision ophthalmic device, called a refractometer, used to determine dioptric power.

What do you need to know?

Automatic refraction measurement is performed with a precision ophthalmic device, called a refractometer, used to determine dioptric power in the treatment of: myopia, astigmatism, presbyopia, in the determination of pupil axis and distance, and in the prescription of visual corrections. With the retroillumination function, checks for the appearance of certain lens opacities can be performed. Based on its results, glasses or contact lenses are prescribed.

Autorefractometry is considered an objective method of examining the refraction of the eye, because the measurements are made without any patient action or subjective information from the patient.

During the procedure, a beam of infrared light emitted by the device, reflected from the retina, is fixed by electronic sensors at the entrance and exit of the eye. The computer program then analyses the measurement results and returns the required values in figures.

In the case of some eye defects, the transmission of the light beam to the retina and its reflection are interrupted. Consequently, auto refraction in such cases is not effective.

Refractometry is interpreted by reading the refractive indices, recorded in 3 columns:

  • First column indicates Sf (sphere) – determines myopia or hyperopia
  • The second column describes the CYL (cylinder) indicator – determines the presence or absence of astigmatism
  • The third column, the AX (axis) indicator shows the angle of the lens fitting in astigmatism
  • PD measures the distance between pupils and is required when making glasses

Keratometry – is a diagnostic procedure used in ophthalmology to determine the curvature of the anterior surface of the cornea and detect various irregularities in its shape. The determination of the curvature and degree of refraction of the cornea is a necessary study for the choice of contact lenses and the diagnosis of corneal disorders. The measurement results are automatically printed. These results are sufficient to allow the initial assessment of the patient’s vision and the choice of glasses or contact lenses.

SEE PRACTICES AND CLINICS

Important note regarding patient consultations and surgery appointments

A patient who cancels a consultation or surgery appointment once, at least one day prior to the scheduled appointment, has the right to a second appointment under the same conditions.
If the patient cancels the second consultation and/or surgery appointment, a new appointment can be made only if the patient accepts to pay for both the consultation and the surgery in advance. This can be done either by payment order or in cash at the clinic reception.
A patient who does not show up for their consultation or surgery, who does not cancel the appointment in due time, or does not answer the clinic’s calls, may request a second appointment only if they pay for the consultation/surgery in advance. 
Patients requesting an appointment for retinal surgeries or laser Prk/Femtolasik/Smile Pro must pay 30% of the cost of the surgery in advance. The appointment will be scheduled only after receiving the advance payment. If the patient is unable to attend the scheduled consultation or surgery, and cancels the intervention at least 48 hours beforehand, they will be refunded in full. If the patient does not show up and does not cancel or contact the clinic at least 48 hours in advance, the advance paid is considered to be lost as damages and will no longer be refunded.
