Lasik eye surgery is a type of surgery performed to correct eye defects for patients deemed appropriate after various tests are performed. In this surgery, the anterior layer of the patient’s eye is removed with the help of a laser and eye defects are treated. The success rate of this surgery applied to treat eye defects such as myopia, hypermetropia and astigmatism is high.
About Lasik Eye Surgery
Patients who want to have LASIK eye surgery are first examined by their doctors. After several tests are done, an appointment is given to the patients whose eyes are suitable for this surgery. After the transparent layer in the eye is numbed with an anesthetic drip, the front part of the cornea is lifted up with a laser device called excimer laser. During this procedure, the patient does not feel pain, but a small feeling of pressure may occur. After removing the thin layer, the process of correcting eye defects begins and the patient is asked to look at the red light. It is not important to move the patient’s eyes during surgery.
Patients who have finished surgery must wear protective glasses on the first night. The next day, they can return to their daily lives. Lasik eye surgery is not suitable for people under the age of 18 and over the age of 65.
What are Eye Sections
The eye is the organ that contains the visual nerves, consists of three layers and transmits the stimulation they receive to the brain. Parts of the eye consist of hard layer, vascular layer and network layer.
It is the layer on the outside of the eye that is white in color and protects the eye against external impacts. The cornea is a transparent layer. The hard layer protects the roundness of the eye and gives hardness.
Blood vessels are found in the vascular layer and this vein feeds the eye. The vessel forms the iris at the anterior part of the layer. Iris is the name given to the colored part of the eye. In the middle of the iris is the pupil and is responsible for adjusting the amount of light coming from outside.
The Retina, also known as the web layer is located in the innermost part of the eye. There are two types of glaucoma: the optic nerve, the optic nerve, and the optic nerve. The image is reflected upside down in the area called the yellow stain. This incoming image reaches the brain from the blind spot. If the image falls to the blind spot, the vision event does not occur. The image from the Yellow Spot can sometimes fall to the right and left. Visual impairment occurs in these cases.
Diseases that occur in the eyes generally occur as a result of visual impairments. Later congenital eye diseases as emerging diseases. Some eye diseases can be treated, while others have not yet found a treatment method.
Eye laziness is caused by one eye seeing less than the other. Although there are no defects in the eyes, this disease is quite common. Experts have stated that one in every 100 people has eye laziness.
Eyesight is gained from infancy. Newborn babies begin to see around them little by little and develop over time. However, sometimes having a vision defect in one eye can cause that eye to see less. Eye laziness can be seen in one eye as well as in both eyes.
Eye laziness, which means that the eyes cannot be used at full capacity, is a difficult to treat disease. The best treatment for this disease is before puberty. For this reason, children should have an eye exam when they are 3.5 or 4 years old for early diagnosis.
Eye laziness can be inherited as well as strabismus, refractive error, cataracts, corneal stain may occur due to such reasons.
The cornea is a transparent layer of glass that covers and protects the front of the colored part of the eye. It protects the eye against impact and dust, such as a shield, while at the same time helping to break the light by 75%. However, this is where UV rays from the sun are filtered. Diseases affecting the cornea;
Allergies are one of the most affecting diseases of the cornea. Allergies increase pollen and dry air together with burning eyes, watering, itching and stinging effects such as allows to be seen. Allergies can also occur due to the use of contact lenses, certain medications and cosmetics.
Corneal dystrophies; this disease can be defined as blurring of part or more of the eye as a result of losing its transparency. This disease may be genetic but may also be caused by unknown causes.
Conjunctivitis is a disease that occurs in the region called conjunctivita. This region is defined as the tissue that covers the white part of the eye and the eyelids. The formation of some infections in this tissue may cause swelling, stinging, itching, redness and burning of the eyes. Progressive conjunctivitis diseases can cause deformation in the cornea and permanent vision loss.
A corneal ulcer occurs in people with too much eye range, i.e. in people whose eyes are open more than normal, as a result of diseases such as dryness and infection. The progression of this disease may cause the person to lose his or her eyesight over time.
Corneal infections; these infections can occur due to factors such as bacteria, fungi and viruses in the eyes. The most common symptoms are burring, watering, pain and blurred vision. As a result of these infections, spotting may occur in the cornea.
Pterygium; this disease is defined as the arrival of pink colored triangular tissue on the cornea. This disease, which is generally seen between 20 and 40 years of age, does not interfere with vision. It’s a recurrent disease.
Dry eye is the disease seen in cases where tears are not produced or less produced. Tears feed the cornea while at the same time protects the eye against harmful infections and provides healing of wounds in the eye. The progression of dry eye can also cause the person to lose his or her eyesight.It often occurs in women during menopause, in people who work at the computer, in dry weather.
Keratoconus; this disease can be described as thinning of the cornea, losing its normal shape, taking the shape of a cone and becoming protruding forward. In other words, it is expressed as thinning and tapering of the cornea with the combination of advanced myopic and astigmatism diseases. This disease begins in adolescence and occurs between 20 and 40 years of age. It must be treated after the age of 40 because its progression can cause serious eye problems.
Cataract is the most common eye disease.. It can be described as a dull lens located behind the pupil. Another expression is that the lens of the eye sees in a misty way. Gradually diminishing vision is its most obvious feature. This disease is often seen in the elderly, but it is a congenital disease that can be seen in people who use cortisone drugs, along with diabetics and after a blow to the eye.
The most common symptoms of cataracts are blurred vision, double vision, night vision impairment, fading and distortion of colors, sensitivity to light, frequent changes in the number of glasses and difficulty in reading. There is no stopping or curative method of cataract disease. The only method for treatment is surgery
Eye pressure, also known as Blackwater, is commonly referred to as glaucoma in medical language. This disease is very insidious and can present itself in very advanced stages and can cause serious vision problems. Eye pressure, pressure inside the eye is often increased due to damage to the visual nerves means.
Glaucoma is more common in people over the age of 40. High blood pressure in the eye does not mean that there will be disease, but it is the biggest trigger of glaucoma disease. This disease can also be seen as genetic diabetes and goiter patients are more common. Long-term use of cortisone drugs and severe blows to the eye are also conditions that trigger eye blood pressure.
The most important symptoms of eye pressure disease are headache in the morning, pain in the eyes while watching television, blurred vision at certain times and seeing rings around the lights of the eye.
Strabismus disease can be defined as the loss of parallelism of the eyes as a result of the loss of function of the muscles in the eye over time. There are 6 novices in each eye. In the case of strabismus, one or more of these muscles may work more or less. These conditions cause strabismus to occur. Strabismus can be seen in one eye and can occur in both eyes. You can also shift up, down, right, or left.
Strabismus may not occur for one reason. Difficult birth, genetic factors, troubled pregnancy period, difficulties in the development of the child and severe diseases in childhood can cause strabismus.
The most important symptoms of strabismus are watery eyes, loss of parallelism, headache, double vision, blurred vision, loss of three-dimensional image, headache and pain in the eyes.
In the eye, inflammation may occur in individual layers or in each layer. Each layer is given a different name in medicine for this condition. The most important symptoms of intraocular inflammation are bleeding in the eyes, feeling severe pain and blurred vision. This inflammation can be caused by diseases and viruses that people undergo. At the same time, a weak immune system triggers this disease. People with joint and immune system diseases can also be seen.
Near and far Visual Impairments
Visual impairment occurs as a result of not breaking the light in the eyes or when the image falls far or near the retina. These disorders are problems of being unable to see far or near and there are 4 different diseases that occur in this way.
Myopic is a disease in which nearby objects are seen as clear but distant objects are blurred. In this disease, the image falls on the front of the retina. This is because the back or front side of the eye is too long or the cornea or lens is more offensive than normal.
Hypermetropia, this defect, the back length of the eye or the cornea or lens breakage is less than normal is caused by. Incoming rays fall on the back of the retina. This disease, which is often seen in infants and young children, is eliminated as age progresses. Headaches and blurred vision are among the most important symptoms.
Astigmatism, myopia, hypermetropia or a mixture of the two as seen in this disease is caused by the different oppressive power of the axes of the eyeball. Blurred vision, shady vision, or double vision are the most important symptoms of the disease.
Presbyopia; this disease occurs with age. People’s eyes are a little more elastic at a young age to see the next person. However, as age progresses, this elasticity decreases and the Rays coming to the eye, such as in hypermetropta, are collected at the back of the retina. Therefore, the problem of not seeing the next of kin arises. This disease starts in the 30s and progresses until the age of 60.
Why Is Eye Surgery Performed?
Eye surgery is performed to eliminate eye defects that are not treatable. With these surgeries, it is aimed to see the patients more clearly and nicely. Eye surgery is also performed for patients with advanced glasses. There are different methods for surgery.
How Is Eye Surgery Performed?
Some tests are performed on the patient before the eye surgery is performed and it is determined which defect is in the eye. The method of surgery is determined by the type of disease. Laser beams can be used during surgery or open surgery can be done.
Types Of Eye Surgery
Eye surgery can also be done clearly with laser. The type of surgery that will be applied to the eyes is decided according to the type of the disease. With the advancement of Technology, a surgical method has been developed for nearly every eye disease.
There is no cure for cataract disease with medication or glasses. For this reason, the disease is treated with surgery. Cataract surgery is performed with phaco method and multifocal method.
Local anesthesia is used in phaco method. The eye is numb with drops and the surgery is performed pain-free. It is important that patients do not move during surgery. In this method, the lens is absorbed and collected by laser beams. In this technique, 2 or 3 mm incisions are made through the eye, but sutures are not used. In this surgery, which takes an average of 20 minutes, the collected lens is re-inserted into the eye in a folding way. Patients can start seeing within a day or two after this surgery and get up immediately.
In multifocal method, both distant and near-sighted patients are treated. These two conditions that occur as a result of cataract disease are treated with the placement of a special lens. However, a special lens is placed. After this surgery, patients can see far and near clearly without the use of glasses.
Myopic means squinting the eyes. In myopic disease, nearby objects can be seen very clearly while distant objects are seen as blurred. Myopic disease usually starts in school-age children and if it cannot be treated immediately, it can lead to learning difficulties. Myopic treatment is often done with contact lenses in patients who want to get rid of the glasses completely. But it can also be treated with the laser method.
The patient’s eyes are opened with the help of a small knife while the laser method is applied. Under this opening cover, laser beams are ejected and the eye defect is corrected. For laser, patients must be over 18 years old, have no progress in their eyes, or have little progress, and no other disease in the eye.
Hypermetropia is an inability to see nearby objects clearly, often seen in conjunction with old age. These patients can not see clearly near the far can see clearly. Glasses and lenses can be used for the treatment of hypermetropia. However, in cases that cannot be treated, surgery is performed. In the treatment of glasses, thin-edged lenses are used which increase the power of refracting light. The Lens has the same lens property.
The surgical methods for the treatment of hypermetropia are Lasik and PRK methods. With these surgeries, hypermetropia greatly regresses and patients are prevented from using glasses or lenses. But hypermetropia is not completely cured.
Treatment Of Astigmatism
Astigmatism is the name given to the formation of double images or blurring of the image by different refractions of light as a result of the deterioration of the structure of the cornea. For the treatment of astigmatism, glasses, contact lenses or surgery are preferred. In cases of astigmatism that cannot be treated with glasses or contact lenses, astigmatism treatment takes place with methods called LASIK, LASEK or no touch.
Excimer Laser Surgery (Eye Scratching)
Excimer laser, popularly known as eye scratching surgery. The purpose of this surgery is to correct eye defects using laser beams. This surgery is used to treat myopia, hypermetropia and astigmatism.
It is possible to correct myopic disease with the problem of being unable to see far away by laser. Myopia can be treated up to -10 degrees with Excimer laser method.
In laser surgery, which is used to treat hypermetropia with near vision problems, hypermetropia can be treated up to +4 degrees.
For astigmatism with blurred vision problem, excimer laser can fix the problem up to -6 degrees.
During eye scratching surgery, laser beams are used to correct the Rays that fall on the cornea. For this reason, more than one excimer laser method can be used to remove the above mentioned ailments.
PRK and Lasek method
Although PRK and Lasek methods are two different methods, the same procedures are performed during surgery. These two types of surgery are very old and are almost no longer used. In the PRK method, the epithelial tissue located outside the eye is removed during surgery and the laser procedure is performed. However, a surgical knife is used when this tissue is stripped.
In Lasek method, the outer layer of the eye is removed with the help of alcohol and laser treatment is done. In both methods, healing begins after 3 to 4 days and the removed tissues are fused back into place. These two methods are very painful and later recovery methods. Using both methods, recovery can take 3 or 4 weeks.
Lasik and Ilassic method
The Lasik method has much more advanced technology than the Lasek or PRK methods described above. The LASIK method does not require removal of epithelial tissue outside the eye. An incision is made on the cornea with the help of a knife called a keratam knife and eye defects are treated with laser. After the process is finished, the cut is put back into place. Because this part is too sticky, and the healing takes place immediately. There is no need to use bandages or stitches after this surgery. Patients only have pain for the first 24 hours and are treated with painkillers.
In the ilasic method, a cut opens in the cornea, as in the Lasik method, but this cut opens with laser beams, not with a knife. The advantage of this method is that there is no risk of microbial diseases occurring as a result of not touching the blade in the eye. In addition, since the surgery is performed by robots and not by humans, the risk of error is very small.
Trans PRK method
The Trans PRK method is also known as no touch. This method has the most advanced technology of laser treatment and treatment is done without contact with the eyes. Eye defects can be treated in about 1 minute using laser beams. Patients can go home without wearing bandages after being treated with this method. The most important advantage of this method is that both eyes can be treated at the same time. The first three days after surgery may be burning, watering, flushing and stinging of the eyes, but 4. day recovery takes place.
What Is Eye Surgery?
Eye surgery is performed in the eye diseases section. All diseases that occur in the eye are referred to the Department of eye diseases and surgery is performed by specialists in the field of eye diseases.
Eye Surgery Prices
Eye surgery prices vary according to the type of surgery performed. However, the rapid advancement of technology and innovations in this area prevents the knowledge of surgery prices in advance. The prices of eye surgery may be different in large and small cities, and will vary depending on the difference of the method used, the level of expertise of the doctor, the hospital and the duration of your stay in the hospital.
Before Lasik Eye Surgery
Before Lasik eye surgery, you will be examined by your doctor. Surgery is decided upon as a result of this examination and some examinations to be performed. A contact lens is a type of lens that is made up of two or more lenses. Because contact lenses temporarily change the structure of the horn and full measurement can not be made during the examination.
Before Lasik surgery, some tests are performed to determine exactly what the eye defect is. In the same way, the condition and structure of the cornea are examined and a clear decision is made for the surgery.
Detailed Eye Examination
It is very important to have a detailed eye examination to determine the defect in the eye and to decide on the type of surgery. This examination takes 30 minutes on average. During this exam, the understanding of the patient’s visual acuity, glasses, examination, eyelids, tear glands and to identify situations around the eye, eye muscle examination, intraocular pressure measurement, fundus examination and biyomikroskopik examination is done.
It is a very important method for the diagnosis of eye defects and in this method the structure of the horn is examined. Thanks to this technique, the cornea is completely mapped. Then the front and rear surfaces are evaluated together. The anterior and posterior surface of the cornea is evaluated. In addition, cornea thickness, cornea diameter, crushing strength and preliminary depth are also measured.
By pachymetry, the thickness of the cornea, the transparent layer at the front of the eye, can be measured. In this way, it is clear whether or not there is blood pressure in the eye.
Pupillae are found in both eyes of the constructions. The device that measures the distance between these pupillas is called a pupillameter. This instrument is a special device that measures the distance from the pupilla to the middle of the nose, and is of great importance, especially as it allows this distance to be known before glasses lenses are inserted.
Check with eye drops
During eye examination, eye drops are used in order to make proper measurements of the instruments and to make the doctor more comfortable to examine them. These drops allow the pupils to grow and remain large for a period of time. This makes measurement and examination easier. This drip is dripped 15 minutes before the examination and its effect lasts approximately 40 minutes.
Preoperative Drug Use
Depending on the type of disease in the eye, your doctor may want you to use some medications. He will usually want these medications taken on the morning of the surgery. However, if you are using long-term medications for diseases such as cortisone drugs and diabetes, you should share them with your doctor prior to surgery.
Examination Of Eye Treatments
Before surgery for the eye is performed, the treatments applied in previous periods should be examined thoroughly. If the eye defect is treated with glasses and lenses, it is examined in detail and the surgical method is decided in this direction.
Determining The Method Of Eye Surgery
In order to determine which method will be used in eye surgery, the eye defect in the patient is determined first. Then checked for glaucoma or another disease in the eye. The surgery method is decided according to the eye structure and the condition of the Horn.
Preparation Of Surgery Plan
If you are using contact lenses before eye surgery, you will be given days according to their softness. The soft lenses should not be used for at least 2 weeks before the operation, whereas the hard lenses should not be used for a week before surgery. These lenses will change the structure of the cornea, so you should stop using them for a certain period of time before surgery. If you are taking long-term drugs that affect your eye, you should decipher them. Your doctor will evaluate these conditions and determine the most appropriate day for the surgery and tell you what you need to do before the surgery.
Smoking and alcohol consumption before Eye Surgery
Smoking and alcohol consumption affect eye surgery as well as any surgery and delay healing. For this reason, at least one week before surgery, your doctor will ask you to stop smoking and drinking alcohol.
Nutrition and Diet Before eye surgery
Light things will be recommended for nutrition prior to surgery. There is no need to follow a diet after or before surgery. Your doctor may ask you to have a light breakfast or not to eat anything on the morning of the surgery.
After Lasik Eye Surgery
After LASIK eye surgery, the patient is given protective glasses for the first day. The first 6 hours after surgery may be pain and stinging sensation in the eyes. These are treated with pain medication. The use of cortisone and antibiotic-containing drops to relieve pain after surgery is of great benefit. Healing of the eye can vary from patient to patient, as well as occur between 4 weeks and 6 weeks on average.
It is normal to feel pain for the first few hours after surgery. There may also be redness and stinging of the eyes.
Pain – Pain
There will be pain for the first 6 hours after surgery. In later times, your pain gradually eases and disappears in about 3 days. During this time, you should use drops and painkillers given by your doctor.
Within a day or two after surgery, you will gain your eyesight. You need to wait 4 weeks to 6 weeks for full recovery.
The first few hours after surgery will be watery and very normal. You will also be given artificial tear drops for your eyes. You should use these drops for a week.
There is no need to apply a special nutrition program after surgery. You can be fed light foods on the first day. Take care to consume plenty of fluids.
You are given drops that you need to use for a week after surgery. These drops contain antibiotics, cortisone and artificial tear drops.
Patients are usually sent home on the same day after lasik surgery. You don’t stay in the hospital when it’s not necessary. However, your doctor may ask you to stay in the hospital for the first day.
Risks, Complications, Side Effects
After LASIK eye surgery, permanent damage is usually not seen and the chances of it being seen are quite small. Permanent eye damage can occur in 1 person in 10 thousand and this is due to damage of the corneal layer during surgery. But thanks to the advancement of technology, this situation is almost uninhabitable.
Since the corneal layer is opened after surgery, there is little chance of infection. As a precaution, patients should use eye drops containing antibiotics for the first week.
Swelling In The Eyes
Another rare side effect is swelling of the eyes. This effect will not be in every patient, as some patients may be more than normal. Swelling is common with infection. It is not permanent and will pass soon.
It is normal for the eye to be watered for the first 6 hours after surgery because of the intervention. This watering will decrease after 6 sata.
Temporary blindness may occur for the first few hours after surgery. This condition does not last long and usually heals completely within a few hours.
There is a possibility of catching germs from the instrument as part of the upper layer is opened during surgery. However, in hospitals, surgery is usually performed with disposable instruments. Therefore, there is very little chance of catching germs. To eliminate this possibility, antibiotic treatment is done.
It is a complication that develops after Lasik surgery. There is very little chance of this complication but it needs to be known. This condition is defined as a corneal disorder that develops due to over-thinning of the cornea. When laser treatment is applied to someone whose corneal map and thickness are not suitable for the laser, ectasia complications may develop. Although rare, there is a possibility of cornea of sufficient thickness and structure.
Cross Linking Treatment
In this treatment, ultraviolet light is sent through a special device to strengthen the bonds inside the horn, which is impaired structure, and a vitamin called B2-vit is used. It is a treatment for ectasia after Lasik surgery. The strengthening of the internal bonds of the corneal layer, which begins to thin and melts, is achieved with this treatment. This treatment lasts between 30 minutes and one hour. Patients should use the eye drops given after treatment without disrupting them.
Things To Be Considered
After LASIK eye surgery, there are certain issues to be considered. You should take your doctor’s medication without interruption. You should not play with your eyes for the first 24 hours after surgery. And you shouldn’t be disrupting your doctor’s checks.
It is recommended not to go out and sunbathe for the first 24 hours after surgery.
Use Of Sunglasses
Your eyes will be sensitive after surgery. It is recommended to use sunglasses when going out in the sun for the first week to prevent damage to your eyes.
You should not take a bath for the first 24 hours after surgery. For the first week, you should take care not to get soap and shampoo into your eyes.
The first 24 sata after surgery is important and you need to rest. You may travel after 1 day, but your doctor may advise you not to travel for a week in case of infection in your eyes.
You can return to your normal life 24 hours after surgery. It’s okay to have sex after 24 hours.
After the surgery, you should use the medications that your doctor wants you to use without interruption and for a week. If necessary, treatment can be continued after a week.
The healing process after surgery is 4 days to one week. However, to ensure full recovery, 4 weeks to 6 weeks should be expected.
Your first doctor’s check-up after surgery will be done a week later. Your second check will be done 1 month later and your third check will be done 3 months later. You have to go to these controls without disruption. After these controls, patients should come back for examination at least 1 time a year.
Nutrition and diet
You do not need to follow any diet after surgery. However, you should consume plenty of fluids, be fed with vitamins, eat plenty of vegetables and fruits, and choose foods rich in vitamin A. It is also important to consume foods rich in omega-3 and antioxidants.
