There are many tonometers currently with different principles of action on the eye and methods of measuring the intraocular pressure. The applanation tonometers of Maklakov and Goldmann as well as non-contact tonometers are widely used in Russia. Tonometers, working on the new principles, such as PASCAL, ORA and Icare are used when more precise and reliable results are required. However, in spite of the newest achievements, there are situations, when such factors are important as the complexity of the methodic, the size of the tonometer (in case of the stationary apparatus), the price, the necessity of the intraocular pressure (IOP) self-control at home etc. Transpalpebral tonometer and the IOP indicator are helpful in such situations. 
Purpose: to approbate climically the IOP indicator of the new generation - IGD-03, calibrated with the Maklakov’s tonometer.
Materials and methods. The new device was compared with the Maklakov’s tonometer. The IOP was measured with IGD-03 and Maklakov’s tonometer by turns in 60 patients (118 eyes) – people with normal IOP and in glaucoma with uncompensated intraocular pressure. 
Results. In the course of the study tonometry findings were divided into two groups - first entered the eye with normal tonometric pressure, and the second - with moderately high and high intraocular pressure. The analysis was conducted both for each group individually and across the dataset.
The data obtained reflect the high correlation of the IOP measured with IGD-03 indicator and Maklakov’s tonometer. 
The new device became easier to use by automatically translating it into its working position and a single statement on the eyelid.
IOP indicator, which is portable, simple in use, allow measuring the IOP through the lids and do not need anesthesia.
Conclusion. The new IGD-03 indicator can be used by ophthalmologists, general practitioners, nurses, optometrists and also by specially trained patients’ relatives (for the IOP measurement at home).
The use of transpalpebral tonometry is a promising in wartime and emergency situations.
