ANALYSIS OF CHANGES IN THE ABERRATIONS OF THE OPTICAL SYSTEM OF THE EYE AFTER FEMTOSECOND INTRASTROMAL RING IMPLANTATION OF THE MYORING IN PATIENTS WITH HIGH MYOPIA IN COMBINATION WITH A THIN THICKNESS OF THE CORNEA [№ 12 ' 2015]
Analysis of changes in the aberrations of the optical system of the eye after femtosecond intrastromal Myoring implantation in patients with high myopia in combination with a thin thickness of the cornea. Femtosecond intrastromal Myoring implantation was performed in 43eyes (of 24patients) with an age from24 to 45years (mean of 34.5±3years) with high myopia in combination with a thin cornea thickness. Corneal aberrometry was studied on aberrometer (Visionix L80 WAVE+, Israel) before and 3months after femtosecond intrastromal Myoring implantation. The value of the spherical component of the refraction was from–9.25 to–17.5diopters (average 13.4±1.4diopters), cylindrical from–1.0 to–4.0diopters (average 2.5±1.2d). The minimum value of pachymetry in the centre ranged from430 to 498μm (average of 464μm± 20μm). The average keratometry value— 44.50diopters. The level of higher-order and lower-order aberrations were evaluated. Spherical aberration and Coma aberrations have analyzed from higher-order aberrations. There is analysis of changes in the aberrations of the optical system of the eye after femtosecond intrastromal ring implantation of the MyoRing in patients with high myopia in combination with a thin thickness of the cornea. Uncorrected distance visual acuity (UDVA) has increased in 8times after MyoRing implantation, corrected distance visual acuity (CDVA) — in 1.5times, spherical component decreased in 8.5times, cylindrical — in 2times immediately after surgery. UDVA improved from 0.13±0.01 3months after surgery, CDVA has not changed. Analysis of the results indicates a high refractive efficiency of this method, the reduction of lower-order aberrations and increasing higher-order aberrations. So, analysis of changes in the aberrations of the optical system of the eye after femtosecond intrastromal Myoring implantation in patients with thin cornea during 3months observation showed a reduction of lower-order aberrations and an increase in higher-order aberrations.

LOCAL FEMTOCROSSLINKING VERSUS STANDARD CORNEAL COLLAGEN CROSSLINKING IN THE TREATMENT OF PATIENTS WITH PROGRESSIVE KERATOCONUS [№ 12 ' 2014]
There is carried out described comparison and evaluation of clinical and functional results of the local femtorosslinking and standard corneal collagen crosslinking (CXL) in patients with progressive keratoconus. 50 eyes of 42 patients with progressive keratoconus stage 2–3 (classified Amsler) were included in clinical follow-up, and were divided into 2 groups of 25 eyes undergoing femtocrosslinking and standard CXL. The observation period was 2 years. Local femtorosslinking is safer and more effective treatment of progressive keratoconus that improves functional parameters as well as the standard CXL.

IS THE "VIRTUAL PINHOLE" JUST A SIMPLE ALTERNATIVE TO MULTIFOCAL IOL [№ 12 ' 2014]
One of the key features of human vision is an activity of perception. The presented objects of different contrast are "turning on" mechanism of the lateral inhibition of neighboring receptor fields of retina to underline and to strengthen the differences. The realization of this mechanism for improvement of the quality of vision, increasing the depth perception and contrast, minimizing diffraction distortion lie in graduated apodization by using intraocular lenses with a virtual aperture (the "virtual pinhole").
