[Pseudo-accommodative intraocular lenses].

This article reviews pseudo-accommodative intraocular lenses (IOLs), providing an analysis of the terminology used in this field of ophthalmology and describing the design of modern IOLs, the technological features used to achieve pseudo-accommodation that meets the needs of patients, particularly the new extended depth of focus (EDOF) IOL technology. The article presents the main types of extended depth of focus IOLs, their description, advantages and disadvantages, as well as comparison with multifocal and monofocal IOLs based on clinical studies conducted in different countries.

[Diagnostic value of the system of Frank's orthogonal leads in inveterate myocardial infarct].

Comparison of data obtained in recording corrected orthogonal leads of the Frank system and 12 classical ECG leads in 118 patients with ischemic heart disease, among whom there were 76 patients with an old myocardial infarction, showed that corrected orthogonal leads may be used in mass population survey with the use of automatic diagnostic machines. It was established that the following ECG indices may be used in recording Frank's corrected orthogonal leads in the diagnosis of cicatricial myocardial changes: amplitude and duration of Q wave, the Q/R and R/S coefficients, the appearance of wave S in lead "Z". In an old myocardial infarction of posterior localization changes are recorded in lead "Y", in infarction of antero-septal localization changes are recorded in lead "Z" and to a lesser degree in lead "X"; in infarction of antero-lateral localization changes are recorded in lead "X" and to a lesser degree in lead "Z".
