According to reviews of laser vision correction, this procedure perfectly restores vision, and also relieves patients of the need to wear contact lenses and glasses. To date, this is one of the most advanced high-tech areas of ophthalmology, which has proven itself in the service market. Every year, millions of people around the world use this procedure and regain the ability to see well. Although, like all surgical interventions, it has its negative sides.
Definition
As doctors say in reviews, laser vision correction is an effective and safe way to correct hyperopia, myopia and moderate and low astigmatism. The procedure is suitable for people who want to improve their vision and forget about the need for optical correction with contact lenses and glasses for many years. This is not always convenient, especially for people working on complexjobs such as police officers, firefighters and doctors.
The essence of the method lies in the fact that the corneal layer is pointwise corrected by the beam, thereby forming its correct curvature. Thanks to this, it is possible to change the light refraction in the eye, focusing it on the retina and getting a clear image pattern at any distance.
Laser vision correction surgery is performed only on an outpatient basis, under drip anesthesia. Pain at the time of the laser is completely absent. The impact lasts for 40-60 seconds. On the same day, the patient can go home and lead a normal life for him. Even before the procedure, the client will know what kind of vision he will receive after the correction.
Pros
Every year, several million laser vision correction procedures are performed worldwide. Over a 20-year follow-up period, this procedure has proven to be highly effective. Now you need to understand the main positive aspects of the correction. There are many, it's tempting enough for every contact wearer:
- Safety - a significant period of observation of patients allows us to reliably speak about the safety, stability of results and effectiveness.
- Used for any visual impairment, but only if there are no contraindications in patients. According to reviews, laser vision correction can help with almost all forms of myopia, astigmatism, presbyopia and farsightedness.
- Minimum age restrictions. Patients in the age group from18 to 55 are considered optimal candidates for holding.
- Speed of operation. Correction time takes from a couple of seconds to a minute, all other time is spent on preparation, it is 10 minutes per eye.
- No pain. Anesthetics are instilled into the eyes, due to which the pain syndrome is completely blocked. The patient feels only a sense of pressure and touch at some stages.
- Outpatient. There is no need to keep the patient in the hospital. After an hour, the patient can go home.
- Quick results. According to patients in the reviews, after laser vision correction (after 2 hours), the client will be able to evaluate the initial results of the procedure. During the first 7 days, vision will improve, and the final result can be discussed only after the final healing of the corneal tissues.
- Predictability of results. After the operation, the shape of the cornea will be preserved for a long time if the patient does not have progressive myopia.
Types of operation
There are many methods of laser vision correction. Reviews about them are different, so you need to understand their popularity and relevance:
- Super LASIK ("Super Lasik") is the most common intervention today. The procedure is performed only according to the personal characteristics of each patient, so the end result is good results.
- LASIK ("Lasik") is the main technique that just laid the foundation forrapid development of correction around the world. The main disadvantage is that it does not take into account the individual characteristics of the structure of the cornea of \u200b\u200beach patient, therefore, in those centers where there is special equipment, Super LASIK completely replaced it.
- Femto LASIK ("Femto Lasik"). The only difference from the previous one is that the cut of the cornea is performed by a special femto laser, hence its name.
- Femto Super LASIK ("Femto Super Lasik") - a similar standard method, but it is performed on an individual basis for all the characteristics of the client.
- Presby LASIK ("Presby Lasik") - the technology provides for age-related changes in patients after 40 years, due to which it corrects for vision at all distances without wearing glasses.
- PRK ("PRK"). This method is used if there are contraindications to standard procedures. For example, when the patient's cornea is too thin. The main disadvantage of laser vision correction is pain and discomfort in the first three days after surgery at the time of restoration of the corneal epithelium.
- Epi-LASIK ("Epi-Lasik") - another version of the standard procedure, which is also used for thin corneas, is extremely rare due to the high cost.
Steps
Almost all laser correction operations consist of 3 main stages:
- Formation of a superficial flap of the cornea, for this a laser or microkeratome is used. The resulting flap is retracted to the side asbook page.
- The shape of the cornea is measured with a laser beam, the individual parameters of each patient are set, and the laser is applied.
- The retracted flap is returned to its place and its engraftment is performed without scars and sutures.
According to reviews, after laser vision correction, if the clinic is chosen correctly, and also a standing doctor who performs the procedure is initially selected, then everything goes well and painlessly, and vision returns quickly.
Indications
In addition to the basic desires of the patient, as with every operation, there must be medical indications for correction:
- sustained myopia up to 10 diopters;
- farsightedness for a long time up to +6 diopters;
- astigmatism up to 4 diopters is allowed;
- individual symptoms (partial correction possible);
- due to the specifics of the job, it is not possible to use contact lenses or glasses.
Contraindications
As in any operation, there are limitations under which the doctor will not perform the procedure:
- patient under 18;
- intervention during lactation or pregnancy is prohibited;
- should not be corrected when vision wear is 0.5 diopters per year;
- if the patient has keratoconus (the cornea has a conical shape), inflammatory ailments;
- with reduced immunity in generalany surgical interventions are prohibited;
- if the patient has diabetes mellitus, anemia, as the rehabilitation process may be aggravated;
- when the client has severe eye disease.
Negative reviews about laser vision correction most often come when they do not adhere to the indications. This is done in new, yet unknown clinics that want to make more money.
Forbidden after correction
During the rehabilitation period, many doctors impose various restrictions on the patient's actions. But all of them almost always come down to one thing - to minimize the load and prevent an aggressive effect on the operated eye. According to reviews, the consequences of laser vision correction can be different, therefore, in order to minimize the negative impact, you need to follow certain recommendations:
- Practically all doctors say that you should not wash your eye that has been subjected to surgery for the initial few days. And also during this period, you should not wash your hair, touch, and even more so rub the living organ. Each mechanical impact at the recovery stage will lead to disastrous consequences. Not very clean hands and dirty water can cause inflammation.
- After the operation, you should not visit the pool, the sea and the river. Saunas and baths are dangerous with high temperatures. Doctors set such restrictions for the first week.
- In the first days after the correction, it is strictly forbidden to visitthe beach, as it is dangerous not only for dirty water getting into the eye. It is required to limit the falling asleep of sand, as well as strong light and sunlight, so as not to provoke a burn. In the spring and summer, doctors advise covering your eyes with high-quality glasses with a high degree of protection after correction. This is required even in cloudy weather.
- Considering the postoperative feedback about laser vision correction and the impression of patients, it is not recommended to sleep on your stomach. As the doctors say, such a restriction applies only to the first night. And some experts do not take into account and do not adhere to it at all. Of course, you don’t need to completely bury your face in the pillow, but the strict presence of the body in one position is not imposed either.
- For the entire rehabilitation period, it is required to abandon excessive physical exertion. This does not mean that the patient should lie completely flat. However, it is required to exclude: dance classes; trips to the gym; fitness; morning run; yoga and Pilates; visiting sports sections, especially for certain types of sports.
- For women after laser vision correction, there are limitations. Decorative cosmetics are forbidden to be used for a week after the operation. After all, mechanical or chemical effects on the eyes, which have just been corrected, will not add to their he alth. The strict ban has also been extended to hair sprays and various aerosols that are potentially harmful to the eyes.
- And also a girl is forbidden to get pregnant for six monthsafter the procedure, as increased hormonal levels and the birth process itself can adversely affect the quality of vision.
- To prevent tobacco smoke from getting into the eyes, the patient is required to limit communication with smoking acquaintances, and also not to visit places where smoking is allowed. If the client himself has such an addiction, then it is required to refrain from it at least for a week.
- At the time of recovery, doctors advise their patients not to drink alcohol. This is done because such drinks blunt the effect of antibiotics, and they are required after correction. And also at the time of intoxication, the risk of damage to the eye increases. Such a ban comes for two weeks after the procedure.
- Don't skip your doctor's regular eye drops. Thanks to this, the healing process will be much faster.
- After the operation, you do not need to bother the body with long reading, working at a computer and watching TV. Starting from the second day, you can perform these actions, but only in doses.
There are pros and cons to this procedure, reviews about laser vision correction are different, therefore, in order to reduce negative manifestations, you must adhere to the above recommendations.
Allowed after correction
During the first few hours after the operation, close your eyes as much as possible so that they can rest. No need to sleep, just lie down in the dark.
After laser vision correction, reviews and postoperative symptoms are different, you need to strictly follow the doctor's recommendations to minimize them.
Most often doctors admit:
- gradually increasing the loads aimed at the organs of vision, with the help of reading, watching videos, as well as various gadgets;
- sleep on your side;
- Use clean paper towels to blot the area of the healing eye when needed.
Post-operative symptoms
Reviews of laser vision correction are different, so you need to know what symptoms a patient can expect after such a procedure. Of course, like any surgical or medical intervention, surgery has its consequences. To date, modern clinics lay the likelihood of complications in 1% of patients.
Main reasons:
- incorrectly set calibration of the equipment, which is necessary for the operation, as well as malfunctions of the vacuum system;
- incorrectly selected nozzle size for the procedure;
- make an overly split or thin incision.
All the facts above are attributed to human error or poor quality equipment.
Unfortunately, even if the equipment works flawlessly and the doctor has the best experience, complications can occur after a successful operation. Most often, their presence is associated with the individual characteristics of the patient, theirimpossible to warn.
It's not uncommon to have problems like this:
- redness and swelling of tissues;
- various inflammatory processes;
- retinal detachment;
- vision deterioration;
- feelings of "sand" in the eye;
- need for reoperation due to insufficient recovery;
- diopters can go from minus to plus and vice versa.
Even after a long period of time (years, months), complications may appear due to the unpredictability of the human body, as well as individual response to intervention:
- the result comes temporarily, and after that you have to repeat the whole procedure again;
- impossibility of further therapy if the patient is dissatisfied with the result;
- thinning of the tissue is formed due to laser exposure, since at the time of correcting the curvature, some part of the tissue is simply cut off;
- high chance of corneal clouding;
- possibility of other eye ailments.
It is very important for the rehabilitation period not to plan pregnancy for six months. Since while waiting for a baby, a woman's immunity is significantly reduced, which must be kept at a high level for the healing of the cornea.
It must be understood that farsightedness, myopia and astigmatism are progressive diseases. With age, vision, of course, will deteriorate, it all depends on how quickly everything happens.
Reviews
Who didlaser vision correction, he can talk about the consequences and sensations that he was overwhelmed with after improving vision. According to many patients, this procedure is completely painless and takes a small amount of time. After the operation, you need to take your he alth seriously so as not to aggravate the difficult situation. According to patients in whom the procedure was successful, it is a great joy to give up contact lenses and glasses. But those who were less fortunate and had various kinds of complications are not advised to perform this procedure.
According to doctors, if you follow their recommendations, you can significantly reduce the likelihood of problems, but complications can still occur. This often does not depend at all on the doctor and his qualifications, the reason for this is the personal physiology of the person and his perception of the surgical intervention. Each person must independently weigh the pros and cons, realize the risks, and then decide whether he really needs it.
