Modern equipment and constant research in the field of ophthalmology can save vision even in the most difficult cases. Laser treatment is one of the most effective vision restoration procedures. Thanks to this method, it is possible to change the shape of the eye cornea in the most gentle way. After laser eye treatment, it becomes possible to see the world around you clearly and clearly. Therefore, everyone who suffers from vision problems should know everything about this procedure.
What laser treatment is for
The human eye is a whole system, which is a very complex mechanism. The nerve endings of the eyes send visual signals directly to the brain system. Through this process, a person sees the world around him. Due to some diseases, the light rays do not focus properly on the retinal membrane of the eye. This contributes to a distorted perception of vision, objects become blurry and fuzzy.
The main task of laser eye treatment is the restoration of refractive effects that prevent you from seeing objects clearly. The laser beam models the cornea of the eye, again restoring its ability to correctly refract light signals that are fixed on the retinal area. With the help of glasses and lenses, you can only temporarily correct this ailment, but only a laser solves the problem once and for all. That is why all ophthalmologists recommend that patients with vision problems undergo laser treatment of the retina and look at the world clearly again.
Who is prescribed laser correction
This method of restoring vision is needed for those people who have impaired refraction. It also represents the ability to create images with the help of the retina, lens and cornea. It is through the cornea that light rays are refracted. This whole complex process is called "refraction". When it is broken, a person sees images and objects indistinctly. This can cause conditions such as farsightedness, nearsightedness or astigmatism.
Indications for laser eye treatment
This vision correction method may be indicated in the following situations:
- For poor vision: myopia, farsightedness, astigmatism.
- If you don't want to wear glasses or contact lenses.
- When your lifestyle or professional activity does not allow you to wear glasses. This category includes people who work in dusty conditions, as well as athletes, doctors and actors.
- For professions that require sharp and clear vision: pilots, doctors, drivers.
When restoring vision in this way, diseases such as myopia, hyperopia and astigmatism disappear forever. Laser eye treatment is done to people aged 18 to 55 years. It is not necessary to do it before, since the eyeballs will not yet be fully formed. If laser treatment is performed at the age of 55, it may not bring a 100% result. Over the years, the lens of the eye is strongly compacted, which leads to a weak perception of laser exposure. Therefore, the sooner you start restoring your vision, the more effective the result will be.
The only exceptions are diseases that are not associated with pathological visual impairment. These include various injuries and damage to the retina and eyeball. In this case, the ophthalmologist conducts an individual examination and only then determines the method of therapy. Laser treatment of a retinal tear in a teenager or child is carried out after a thorough analysis of the possible complications of the operation.
Contraindications for laser treatment
Not everyone can take advantage of this amazing opportunity to restore vision. Surgery is contraindicated in the following cases:
- Under 18 years of age. Laser eye treatment in children is prohibited.
- During pregnancy and lactation.
- When suffering from diabetes.
- Laser correction should not be done for those who suffer from immunodeficiency or systemicdiseases.
- Cataract of the eye. Laser treatment will need to be carried out in two stages.
To exclude complications, it is mandatory to conduct an examination of the whole organism. For the treatment of diseases such as cataracts, myopia and retinal tears, a coagulation procedure is performed before recovery.
Laser coagulation treatment
This surgery is done for various pathologies of the retina. Laser coagulation improves vision, restores blood circulation in the vessels, and also prevents the possibility of fluid flowing directly under the retina. Treatment is performed according to the following indications:
- When there is a violation in the work of blood vessels on the retina.
- Retinal dystrophy.
- Vein thrombosis.
- Retinal detachment.
- Myopia.
- Cataract.
Pros of laser treatment
This laser eye treatment has many benefits. Among them, the following should be highlighted:
- Fast recovery process.
- No pain during and after surgery.
- Absolutely harmless.
- Efficiency and guarantee of 100% restoration of vision.
- You can have surgery until the age of 55.
- Strong results for many years.
- Both eyes are corrected in one procedure.
- Laser correction can be done for any ophthalmic problem.
The above advantages make laser eye treatment the best methodrestoration of vision. However, there are no ideal methods, so even this procedure has minor disadvantages.
Disadvantages of laser treatment
Thinking about the disadvantages of laser vision correction, one can single out a slight discomfort from the operation, which will last about 4-5 days. Particularly sensitive people may experience pain. After restoring vision with a laser, you will have to use eye drops for some time. They will help the eyes rehabilitate themselves from exposure to the beam.
Based on the reviews of laser eye treatment, we can conclude that in rare cases the procedure is accompanied by complications. These include various damage to the nerve endings and the cornea of the eye. But this is possible only with an unsuccessful choice of clinic and doctor. Such complications must be corrected immediately, otherwise they will lead to visual impairment. Another disadvantage of laser correction is the inability to do household chores for some time after treatment. Computer use, reading and many other habitual activities will be banned.
Preparation for treatment
Such a serious technique requires special preparation. A week before the proposed vision correction, it is necessary to stop using lenses and glasses. To avoid possible difficulties associated with visual impairment, it is better to take sick leave or vacation at work. During this period of time, the eyes will rest from tension, and the corneatakes on its natural form. Thanks to this preparation, the operation will be as efficient and easy as possible, and the recovery period will take much less time.
In addition to giving up glasses and lenses, it is necessary to pass some tests and be examined by an ophthalmologist. The day before the operation, you need to give up smoking and alcohol. Also, you can not use decorative cosmetics. In the evening before the procedure, you should thoroughly cleanse your face, hair and give the body a good rest. If you are very excited or anxious, you should drink a mild herbal sedative.
How is the operation going
Before starting laser treatment, the doctor instills an anesthetic in the patient's eyes. After that, you can sit on the operating table and prepare for the operation. To avoid blinking, special dilators are inserted into the eyes. After that, the doctor proceeds to active actions. The operation is usually carried out in three stages:
- During the first stage, the top layer of the corneal patches is separated. The doctor performs this procedure with a microsurgical instrument called a microkeratome. These actions help open access for work in the middle layer of corneal tissue. The stage lasts only a few seconds and the person does not experience pain.
- At the second stage, the doctor vaporizes the homogeneous inner layer of the cornea until it takes the desired curvature.
- Finally, the upper protective layer is returned to the cornea.
The whole operation is going throughpretty fast. The patient does not need to remain under observation in the hospital. But he needs an escort to take him home and take care of him for a while.
Rehabilitation after laser correction
To quickly begin to see well, you must adhere to the following recommendations of the postoperative period:
- Don't sit at the computer and read. Based on the reviews about laser treatment of the retina, this rule is a must.
- Do not wear makeup.
- Prevent water from entering the eyes.
- Do not rub your eyes and protect them from various injuries.
- Do not go to the sauna, solarium and bath for about a month.
- Don't go to the gym and limit yourself to light exercise whenever possible.
- Only go to work or school with a doctor's approval.
- Do not smoke or drink alcohol.
These measures should be followed for 1 to 4 weeks, depending on the rate of vision recovery.
