lenses. Patients were admitted on the background of antibacterial
treatment, on average, on the 7th day from the onset of the disease (in 3
cases on the 20th day). Visometry, biomicroscopy, ophthalmoscopy, and
bacteriological examination of the corneal surface were performed.
Results.We managed to achieve stable remission in two patients (they
took ophtax, tobradex, phloximed). Against the background of powerful
conservative treatment in 9 people, the disease had a continuously recurring
course with short periods of remission. Subsequent exacerbations were
more severe, with multiple complications: perforation of the cornea,
secondary hypertension, complicated cataract; in 2 patients - with lysis of
the lens and prolapse of the membranes of the eye. Due to the ineffectiveness
of conservative treatment, keratoplasty surgery was advised to nine
patients. In 2 patients, cataract extraction was additionally performed. In the
long-term period, 7 patients had visual acuity of 0.3-0.4. In 2, an eye
enucleation operation was performed.
Conclusions. A continuously recurring course and subsequent serious
complications require the development of special tactics for treating
patients with purulent corneal ulcers while wearing soft contact lenses.
Most patients were advised to have keratoplasty surgery.

COMPLEX TREATMENT OF COMPUTER VISUAL SYNDROME IN
SCHOOLCHILDREN
D. Kakharova,M. Mamadieva, D. Kakharova
Relevance. General computerization of recent years has brought new
challenges. One of them is computer visual syndrome (GLC).
Purpose. The purpose of our study was to study the various
manifestations of CVD in adolescent children and to develop a protocol for
prevention and treatment.
Materials and Methods. Under our dynamic supervision, there were 60
patients aged 12-14 years who spend more than 4 hours behind monitor
screens. All patients underwent standard ophthalmologic examination,
including
visometry,
skioscopy,
biomicroscopy,
ophthalmoscopy,
autorefractometry. Also consider complaints of patients surveyed reserve
accommodation, a study of the tear film stability
Results. After analyzing the data from the above studies, we found that
2/3 of children (39 people) complained of visual fatigue in the evening, pain
and dryness in the eyes, their redness. Signs of instability of the tear film

were observed in 11 patients, 46 of them had myopia or accommodation
spasm.
We have developed a protocol for the prevention of GLC:
1. Identification and adequate correction of refractive errors.
2. Compliance with the rational regime of visual load.
3. Stimulation of disaccomodative muscles with drugs.
4. Tear replacement therapy.
5. Vitamin therapy and antioxidant therapy.
Conclusions. Thus, the treatment of GLC should certainly be
comprehensive and include all of the above activities.

STUDY BORING THE BORE HOLES OF THE BIG DIAMETER ON ALLUVIAL
DEPOSITS USEFUL FOSSILIZED
S. Abdullaev
In Uzbekistanâs quarries and mines, the use of modern drilling
equipment with hydraulic impact actuating equipment is increasingly being
used, which in turn raises the question of establishing optimal basic
technological dependencies and modes of hydraulic impact drilling in
specific mining and geological and mining and technological conditions of
field development.
Complexes of technical means for drilling large-diameter exploratory
wells in placer mineral deposits (gold, tin) in permafrost distribution areas
allow drilling wells up to 200 m deep and are used instead of impact-
mechanical and rotary drilling with air blowing.
The efficiency of using EPH complexes (EPH - equipped with pneumatic
hammers) is due to an increase in productivity by 35â40% relative to
mechanical shock drilling and by 45â55% relative to rotary drilling with air
blowing. This in the northern regions allows you to get an economic effect
of at least 10-12 rubles. per 1 m of the well. In addition, the introduction of
EPH complexes in the practice of exploring alluvial deposits eliminates
seasonality - the main drawback of shock-mechanical drilling.
A significant advantage of pneumatic percussion drilling with EPH
complexes over other technical means (shock mechanical drilling, rotary
drilling with air purging and flushing with special solutions) is the increase
in the reliability of geological information. This increase is determined by
the possibility of obtaining 95-100% undisturbed and thawed core during
pneumatic impact drilling, which makes it possible to make very precise
