Excimer laser refractive surgery is becoming more and more popular every year. In our clinic, special attention is paid to its high quality and predictability.

Excimer laser refractive surgeries are capable of inducing various types of higher-order optical aberrations, especially coma-like and spherical, which negatively affect the quality of vision. As a result, patients may complain of halos around light sources, decreased contrast visual perception in low light conditions, deterioration of night vision.

The term “coma aberration” refers to the aberration of oblique beams of light incident at an angle to the optical axis of the lens, and in relation to the optical system of the eye - at an angle to the visual axis.

One of the complications of keratorefractive surgery is decentration of the ablation zone. Its significant displacement relative to the visual axis (in in some cases 1000 microns or more) can manifest itself in a decrease in best-corrected visual acuity, the appearance of monocular double vision, deterioration of night vision, difficulty reading, the presence of glare and halos around light sources due to the presence of a “prismatic” effect, irregular astigmatism, coma and other higher aberrations orders of magnitude

In particular, centering the ablation zone when correcting ametropia using photorefractive keratectomy (PRK) and LASIK should be adjusted for the displacement of the visual axis of the eye relative to the center of the pupil. Failure or incorrect execution of this stage of the operation, according to a number of authors, inevitably leads to a decrease in postoperative visual acuity due to the induction of higher order aberrations such as coma and trefoil, which corresponds to the decentration of the optical zone (DOZ), visualized on keratotopograms.

IN recent years the frequency of cases of decentration of the ablation zone decreased. This was achieved by improving the Eyetracking system and carrying out personalized operations taking into account the kappa angle (displacement of the visual axis relative to the center of the pupil). However, the problem still requires further study.

Thus, in particular, determining the center of the laser ablation zone is often indicative. It is especially important to determine the center of the laser ablation zone when correcting farsightedness, where the tip of the cone-shaped protrusion of the corneal surface formed by the excimer laser must exactly coincide with the optical axis of the eye. After all, even a slight decentration of the ablation zone can lead to residual complex hyperopic and irregular corneal astigmatism. This important nuance is one of the disadvantages of excimer laser correction of hypermetropia and hypermetropic astigmatism.

According to some statements, when correcting myopia and myopic astigmatism, minor deviations from the center of the visual axis (up to 1 mm) are not of fundamental importance, since they practically do not affect the quality of vision. At the same time, there is an opposite opinion. So, Makovkin E.M. recommends for the degree of deviation of the visual axis eyeball relative to its anatomical axis from 0.2 mm or more, it is necessary to take this into account important point when performing excimer laser surgery.

Given the ambiguity existing opinion, we felt that this aspect required greater clarity and specification. This is due to the fact that refractive operations should be as predictable as possible, since they are performed on young, healthy, socially active people.

Therefore, we decided to use our own clinical material to study whether the formation of unwanted optical aberrations is affected by the implementation of one or another excimer laser surgery technique.

Target- to study the relationship between postoperative spherical and coma-like aberrations and the absence/presence of a displacement of the ablation center relative to the visual axis during femtoLASIK in patients with mild and moderate myopia.

Material and methods.

An in-depth examination of 41 patients with mild and moderate myopia (82 eyes) who underwent refractive surgery was carried out. The selection criterion was the presence of postoperative visual acuity, strictly similar to the initial, maximum correctable visual acuity (without loss of a single line). The age of the patients ranged from 18 to 37 years, on average 28.3±0.6 years.

There were 18 men, 23 women. The sphero-equivalent of clinical refraction averaged 3.5±0.2 diopters. Sixty-nine eyes had compound myopic astigmatism ranging from 0.5 to 2.0 D. The average ophthalmometry value was 43.68±0.2 diopters.

Two groups of patients were formed depending on the presence/absence of a displacement of the ablation center relative to the visual axis. Both groups were matched in age, gender, degree of myopia, degree of astigmatism and preoperative corneal parameters. In group 1 (21 patients, 41 eyes), when performing refractive surgery, the ablation center was shifted relative to the visual axis. In group 2 (21 patients, 41 eyes), corneal stroma ablation was performed strictly in the center of the pupil.

The range of ablation displacement in group 1 was: horizontally - from 50 to 300 µm, on average 141.0±9.1 µm; vertically - from 50 to 350 µm, on average 152.6±10.2 µm.

In addition to the standard diagnostic ophthalmological examination, spherical aberrations and coma aberrations were examined in all patients (VisxWaveScan aberrometer, USA); keratotopography (Pentacam projection keratotopograph, Oculus, Germany).

FemtoLASIK technology was used using the VizuMax femtosecond laser (Carl Zeiss Meditec, Germany). Excimer laser ablation in all cases was performed using a scanning type excimer laser Microscan-Visum-300 (Optosystems, Russia). A myopic algorithm was used with the following exposure parameters: “flying spot” technology, wavelength 193 nm, spot diameter 0.9 mm, scanning frequency 300 Hz, optical zone diameter 6 mm.

All operations were performed by the same surgeon. In all cases, the maximum possible, predictable refractive result was achieved.

After femtoLASIK, spherical aberration and coma aberration were measured in each group (at baseline and on day 5), and the presence of significant changes in these values ​​was analyzed. When comparing groups, methods of mathematical statistics (Student's test) were used. When testing the null hypothesis, the critical level of statistical significance was taken equal to 0.05.

Results and discussion.

In patients of group 1, the initial value of spherical aberration was 0.01±0.02 µm. On the 5th day after surgery, this indicator was 0.11±0.03 µm. The significance of the differences turned out to be p=0.04 (p<0,05), т.е. сферическая аберрация достоверно увеличилась.

The coma aberration in group 1 was initially 0.15±0.02 µm; on the 5th day it corresponded to 0.17±0.02 µm. The significance of the differences turned out to be 0.063 (p>0.05), i.e. she hasn't really changed.

Visual acuity in group 1 after surgery was 0.95±0.01.

In patients of group 2, the initial spherical aberration was 0.05±0.16 µm; on the 5th day it increased to 0.11±0.03 µm. The significance of the differences turned out to be p=0.01 (p<0,05), что свидетельствует о достоверном увеличении сферической аберрации.

The coma aberration in group 2 was initially 0.13±0.01 µm; on the 5th day after femtoLASIK it increased to 0.21±0.02 µm. The significance of the differences was p=0.04 (p<0,05), т.е. показатель аберрации кома достоверно увеличился.

Visual acuity in group 2 was 0.95±0.01.

When comparing the spherical aberration values ​​of both groups, it turned out that they were approximately comparable before surgery: 0.01 ± 0.02 and 0.04 ± 0.02, respectively (p = 0.22, i.e., no differences). On the 5th day they turned out to be moderately increased, but their correlation did not change: 0.11±0.03 and 0.11±0.03 (p=0.95, i.e. there are no differences).

Coma aberration in both groups was 0.15±0.02 and 0.13±0.01, respectively (p=0.348, i.e. no differences). By the 5th day after surgery, its values ​​corresponded to 0.17±0.02 and 0.21±0.02, i.e. there were no differences in both groups.

Thus, the analysis showed that the femtoLASIK technique for surgical correction of weak and moderate myopia allows one to achieve the maximum possible, predictable refractive result, regardless of the presence or absence of a slight shift in the ablation center. In both cases there was a moderate increase in the degree of spherical and coma-like aberrations.

Conclusion.

A moderate displacement of the ablation center relative to the visual axis by an average of 150 μm when performing femtoLASIK technology for the correction of weak and moderate myopia did not have a negative impact on the favorable prognosis of refractive and functional indicators of the eyes; had no significant effect on postoperative spherical aberrations and coma aberrations.

Vertebral displacement or spondylolisthesis is a disease of the spine, more often acquired than congenital and characterized by displacement of a vertebra in relation to the underlying one.

Depending on the extent to which the vertebra is displaced, there are five degrees of spondylolisthesis:

  • 1st degree – the vertebra is displaced by a quarter. There are practically no complaints, sometimes minor pain bothers me.
  • 2nd degree – the vertebra is displaced by half. Stable aching pain appears and muscle weakness appears.
  • Grade 3 – the vertebra is displaced by three quarters. I am concerned about severe pain in the back, adjacent systems, muscle weakness, disruption of the functioning of internal organs, changes in posture and gait.
  • 4th degree – the vertebra is completely displaced. Worries include severe pain, weakness in the arms, disturbances in posture and habitual body position, changes in the function of adjacent internal organs and systems.
  • Grade 5 - the vertebra is displaced and sagging. Spinal cord compression syndrome occurs and possible ruptures. Severe radicular pain and partial paralysis. There is limited movement.

In the thoracic region, such changes are quite rare. Most often, displacement occurs in those parts of the spine that are most mobile - cervical, lumbar. Displacement in the lumbar region is preceded by traumatic fractures of the articular processes, which gradually leads to the development of displacement, which leads to the development of lameness, muscle weakness in the legs, and difficulties in movement.

To prevent displacement of the vertebrae or to prevent it from progressing to a more advanced stage. If you experience back pain after falling on your back or physical activity, you should consult a doctor as soon as possible.

Causes of vertebral displacement

The causes of vertebral displacement can be different - these are injuries, congenital pathologies, and age-related pathologies of the vertebrae. But in addition, there are factors that predetermine the displacement of the vertebrae: hereditary changes in the vertebral body, repeated injuries to the spine, and its hyperextension.

There are 5 types of vertebral displacement:

  1. Congenital pathology of the vertebra, due to which the vertebra is not fixed in the department and is constantly displaced.
  2. Isthmic vertebral displacement is a defect of the interarticular surface of the vertebra. Often occurs in athletes due to repetitive trauma or overextension.
  3. Degenerative displacement. Develops in old age, the cause is arthritic changes in the joints of the vertebrae.
  4. Traumatic displacement. It occurs as a result of direct trauma, most often a fracture of the pedicle, plate or arch of a vertebra, or facet joint.
  5. Pathological displacement. Develops with tumor damage to bone tissue or tissues adjacent to the vertebra.

Regardless of the cause of the displacement of the vertebrae, the first sign that is alarming in this case is back pain (in the later stages - disturbances in the functioning of internal organs). If pain occurs, especially when moving, exercising, or after falling on your back, you should consult a doctor. This will help you take the necessary measures in a timely manner and avoid irreversible changes in the spinal column.

Symptoms of vertebral displacement

Symptoms of vertebral displacement do not appear immediately, so at first it is difficult to diagnose the displacement on your own, without medical help. Gradually, pain in the affected part of the spine begins to bother, mobility decreases, a feeling of numbness appears, and after physical activity the pain increases. Muscle spasms, numbness in the arms and legs, and lameness appear.

At the first degree of displacement, the pain is insignificant, but intensifies when turning the body or during physically difficult work. With the second degree of displacement, the pain is constant and becomes unbearable with movement and exertion. In the third degree, visible disturbances appear - posture changes, lameness appears, and the range of movements decreases. With the fourth or fifth degree, gait and posture change. Upon visual examination, curvature and “subsidence” of the damaged vertebra are noticeable, and constant radicular pain and muscle pain are disturbing. The functioning of internal organs and systems is disrupted.

In general, the prognosis for vertebral displacement is favorable. In the early stages, displacement is treated conservatively, but a complex of physical therapy and special corsets are indicated, and in severe cases, surgical intervention is performed. And the sooner the patient consults a doctor, the more effective the treatment result will be.

Displacement of the cervical vertebrae

Displacement of the cervical vertebrae is common in children, especially before one year of age. Causes described include birth trauma and improper handling of newborns. Often, displacement of the vertebrae in children occurs if you pick up the child without holding the head. In adults, displacement of the cervical vertebrae occurs with osteochondrosis, dysplasia of the intervertebral discs, injuries of the cervical spine and previous operations.

Symptoms include headache, dizziness, neck pain radiating to the arms and shoulders, chest, and sensory disturbances.

Displacement of the thoracic vertebrae

Displacement of the thoracic vertebrae is less common, but develops after injury, falling on the back or lifting heavy objects, also if spinal surgery has already been performed or there are tumors. As a result of the displacement, the intervertebral canal narrows, and the following symptoms appear:

Chest pain, weakness, compression of the spinal cord and radicular pain, pain in the intercostal spaces and disruption of the functioning of internal organs.

Nervousness gradually appears, memory deteriorates, migraines and hypertension develop, high intraocular pressure appears, and hearing loss occurs.

Even ancient people united the stars in our sky into constellations. In ancient times, when the true nature of the celestial bodies was unknown, residents assigned the characteristic “patterns” of stars to the outlines of some animals or objects. Subsequently, the stars and constellations became overgrown with legends and myths.

Star maps

Today there are 88 constellations. Many of them are quite remarkable (Orion, Cassiopeia, Ursa Ursa) and contain many interesting objects that are accessible not only to professional and amateur astronomers, but also to ordinary people. On the pages of this section we will tell you about the most interesting objects in the constellations, their location, and provide many photographs and entertaining video recordings.

Thanks to observations by astronomers, it turned out that the location of stars gradually changes over time. Accurate measurements of these changes require many hundreds and thousands of years. The night sky creates the appearance of a countless number of celestial bodies, randomly located in relation to each other, which often outline constellations in the sky. More than 3 thousand stars are visible in the visible part of the sky, and 6000 in the entire sky.

Visible location


Constellation Cygnus from Johann Bayer's atlas "Uranometria" 1603

The location of dim stars can be determined by finding bright ones, and thus the necessary constellation can be found. Since ancient times, in order to make it easier to find constellations, bright stars have been grouped together. These constellations received the names of animals (Scorpio, Ursa Major, etc.), were named after the heroes of Greek myths (Perseus, Andromeda, etc.), or simple names of objects (Libra, Arrow, Northern Crown, etc.). Since the 18th century, some of the bright stars of each constellation began to be named by letters of the Greek alphabet. In addition, about 130 brightly shining stars were named after them. After some time, astronomers designated them with the numbers that are used today for stars of low brightness. Since 1922, some large constellations were divided into small ones, and instead of groups of constellations, they began to be considered sections of the starry sky. There are currently 88 separate areas in the sky called constellations.

Observation

Over the course of several hours of observing the night sky, you can see how the celestial sphere, which includes the luminaries, as one whole, smoothly rotates around an invisible axis. This movement was called diurnal. The movement of the luminaries occurs from left to right.

The Moon and the Sun, as well as the stars, rise in the east, rise to their maximum height in the southern part, and set on the western horizon. Observing the rising and setting of these luminaries, it is discovered that, unlike the stars, corresponding to different days of the year, they rise at different points in the east and set at different points in the west. In December, the Sun rises in the southeast and sets in the southwest. Over time, the points of west and sunrise shift to the northern horizon. Accordingly, the Sun rises higher above the horizon at noon every day, the length of the day becomes longer, and the length of the night decreases.


Movement of celestial objects along the constellations

From the observations made, it is clear that the Moon is not always in the same constellation, but moves from one to another, moving from west to east by 13 degrees per day. The moon makes a full circle in the sky in 27.32 days, passing through 12 constellations. The Sun makes a similar path as the Moon, however, the speed of the Sun is 1 degree per day and the entire path is completed in a year.

Zodiac constellations

The names of the constellations through which the Sun and Moon pass were given the names of the zodiacs (Pisces, Capricorn, Virgo, Libra, Sagittarius, Scorpio, Leo, Aquarius, Taurus, Gemini, Cancer, Aries). The Sun passes through the first three constellations in the spring, the next three in the summer, and the subsequent ones in the same way. Only six months later those constellations in which the Sun is now located become visible.

How many stars and constellations are there in the sky? If everything is more or less clear with the constellations, then with the stars it’s quite difficult - there are many of them, oh-so-very many. Let's look at the number and name of stars and constellations and name them alphabetically.

Stars

If you go out late at night and look at the sky, you will see a fascinating picture. Hundreds of stars, some bright, others barely noticeable, they also differ in color. Why is this so?
What is a star? This is a cosmic gas body that emits colossal thermal and light energy. Light and thermal energy is obtained as a result of nuclear reactions and all this is retained by gravity.

Stars have different ages and therefore each has its own luminosity. The color varies from blue, white to red.

The human eye is not able to see all the stars. Our vision is limited and a person, under favorable conditions, sees approximately 6 thousand stars. This is in both hemispheres, 3 thousand each. But not all of them have their own names; the most striking ones are named; there are approximately 290 of them.

In ancient times, people looked at the night sky, observed, remembered and gave beautiful names to the stars and constellations. For an ancient and uneducated person, the stars were mysticism, a deity.
Later, with the development of civilization, man used the stars to navigate the seas and oceans. This was the only landmark when there was water all around.

How stars and constellations were named

The first names were given by ancient peoples who lived in Egypt, Syria, and Mesopotamia. Where the first signs of civilization appeared. Two dozen names have survived to this day.
Next were the Greeks. True, they didn’t really study the new stars, they simply renamed the old ones, and added a few things.
During the heyday of the Roman Empire, the Romans also gave names to many stars. But Rome fell, and science along with them.
Arab culture made a great contribution to the names and discovery. The Arabs had a heyday, and they actively named the stars, but also renamed Greek and Roman names. At the same time, Western Europe was experiencing dark times.
In the 16th century, bright times came for Europe, science began to flourish. Astronomy including. Typically, Arabic names were not renamed, but the Latin alphabet was added.
In Europe, in 1603, for the first time in history, a map of constellations with names was released. The German amateur astronomer Johann Bayer succeeded in this.
Also important, he proposed the principle of naming stars in a constellation. The basis was the Greek alphabet: Α α (alpha), Β β (beta) and until the last letter Ω ω (omega). The brightest star in the constellation was called the first letter of the Greek alphabet and as it faded, the next letter in order came.

The most famous and brightest stars

Let's look at the brightest and most famous stars that are clearly visible from Earth with the naked eye.

Adara is the second brightest star after Sirius in the constellation Canis Major.

Acrux is an alpha star in the constellation of the Southern Cross.

Aldebaran is an alpha star in the constellation Taurus. Aldebaran is the brightest star in the constellation Taurus and only in the entire Zodiac.

Altair is an alpha star in the constellation Aquila. A bright white star that can be observed in the northern hemisphere.

Antares is an alpha star in the constellation Scorpio, red beyond the giant. On the territory of Russia it can be observed in the south or central regions.

Arcturus is an alpha star in the constellation Bootes, an orange giant. It can be observed from Russian territory all year round, but best in spring.

Achernar is a beautiful double alpha star in the constellation Eridanus. She is beautiful not by name, but by color, she has a beautiful blue color. In general, of course, it is customary to give beautiful names to stars and constellations.

Betelgeuse is an alpha star in the constellation Orion. A very interesting star to observe, it is a red supergiant, the future of the star is uncertain. It could go supernova or shed its shell and become a white dwarf.

Vega is an alpha star in the constellation Lyra, the most famous star. Can be observed from Russian territory.

Gacrux is the third star located in the Southern Cross constellation and the third brightest in this constellation.

Deneb is an alpha star in the constellation Cygnus, translated as a tail.

Canopus is an alpha star in the constellation Carina. Unfortunately, the yellow-white star is not visible from Russian territory.

Capella is an alpha star (yellow giant) in the constellation Auriga, translated as goat.

Castor is the second brightest star in the constellation Gemini.

Mimosa is a beta star, that is, the second brightest star in the Southern Cross constellation.

Pollux is a beta star in the constellation Gemini. This is the brightest star in the constellation, although it is beta, it is brighter than alpha.

Procyon is a double alpha star in the constellation Canis Minor, which means in front of the dog.

Regulus is an alpha star in the constellation Leo. The young star is only a few hundred million years old. The star has a very strong rotation.

Rigel is a beta star in the constellation Orion. Translated, it means leg, referring to the leg of Orion.

Sirius is an alpha star in the constellation Canis Major, the brightest in the constellation. This star can be observed from almost any point except the far north. Sirius has a small luminosity, but it is close to the Earth and is clearly visible in the night sky from here.

Spica is an alpha star in the constellation Virgo. You can watch from anywhere in Russia.

Toliman - an alpha star is located in the constellation Centaurus, visible to the naked eye as one star. It is actually a triple star, a yellow dwarf, an orange dwarf and a red dwarf.

Fomalhaut is an alpha star in the constellation Juvenile Pisces. The translation sounds like the mouth of a young fish. In Russia it can only be observed in the south.

Hadar is a double beta star in the constellation Centaurus. Another name for the star Agena.

Shaula is a star located in the constellation Scorpio and the second brightest in this constellation.

What is a constellation? At different times, the constellations were called differently. In ancient times, these are figures or objects that are formed by stars. Now this is done in order to more freely navigate the starry sky.

At the beginning of the 19th century, it was decided to divide the starry sky into constellations. The International Astronomical Union worked on this for 13 years, and in 1935 all work was completed. The number of constellations was also determined, there are no more and no less, out of exactly 88. We will list all the names of the constellations and the list in alphabetical order.
