What is eye LASIK?


LASIK eye surgery is a type of eye surgery, in which vision problems are solved with the help of a laser. Eye LASIK is one of the newest eye procedures. In this surgery, a laser is used to make a precise cut on the cornea of the eye. In eyes that do not have vision problems, the cornea refracts the light and transmits it directly onto the retina at the back of the eye. But in eyes with nearsightedness, farsightedness or astigmatism, the light is not focused in the right place and the vision is blurred.


Most people are satisfied with the results of laser eye surgery. Side effects such as dry eyes are common in this procedure. The result of the operation depends on eye defects and other factors. People with mild myopia have the most success in this surgery

Types of eye surgery


Different techniques are used in all types of eye surgery to fix eye defects. Each technique has advantages and disadvantages. The eye surgeon may be skilled in some laser eye surgery methods. Depending on the conditions and preferences of the doctor, one of the following methods is used to perform eye surgery.


  1. Photorefractive keratectomy (PRK)


In the PRK method, instead of removing the flap (thin layer on the cornea), the upper part (epithelium) is scraped. It takes 3 to 4 days for the corneal abrasion to heal. In the short term, the patient experiences moderate pain and blurred vision. The doctor chooses this method in people who may be injured in their eyes during their daily activities. For example, athletes, people working in the police force or the army are included in this category. Even with this method, there is a risk of tearing the eyeball. So, you should take care of the health of your eyes while performing activities.


  1. Lasek eye surgery (LASEK)


LASIK is very similar to eye LASIK. For people who have a thin cornea, the doctor suggests this method. In this case, the flap is separated using a special cutting device (microkeratome). The cornea is exposed to ethanol. In the LASIK operation, the eye surgeon removes less corneal tissue.


  1. Epithelial laser (epi-LASIK)


This method is somewhat similar to the Lasak method. In this method, the doctor separates the epithelium from the middle part of the cornea. This is done using a mechanized device. Then the cornea is reshaped with a laser.


  1. Lens implantation


Corrective lenses can be surgically placed in the eye to improve vision. This procedure is usually performed as part of cataract surgery. For elderly people, lens implantation can be an alternative to eye LASIK. Because they may need cataract surgery in the future.


  1. Biopethic


This method is not suitable for everyone. Biopetic is actually a combined method. One or more eye surgery techniques are combined, such as LASIK eye surgery and lens implantation.


Procedures for performing LASIK eye surgery


At first, the doctor will coordinate an examination session with you. In this session, the ophthalmologist examines the size of the cornea and its thickness and determines the exact amount of tissue that should be removed from the eye. Doctors generally use waveguide technology for accurate assessment. In this test, the scanner provides a detailed chart similar to topography. The more accurate the measurements, the better the surgeon can remove the corneal tissue.


Eye LASIK usually takes 30 minutes or less. An anesthetic drop is poured into the eye. Then the doctor uses a device to hold the eyelids open. Using a small blade or laser, the surgeon removes the flap on the eye. After that, the doctor accesses a part of the cornea to change its shape.


The surgeon uses a laser to reshape parts of the cornea. A small amount of corneal tissue is removed with each laser beam pulse. After reshaping the cornea, the surgeon returns the flap to its previous position. The flap usually heals without sutures. During the procedure you will be asked to focus on a point of light. In this case, you keep your eyes steady. You may feel an odor during the procedure. Some people compare this smell to the smell of burnt hair.


Important points before eye LASIK surgery


Be sure to have a consultation with an eye surgeon before eye LASIK surgery. Some factors can increase the complications and damage of eye LASIK. Also, the result may not be ideal for the person. If you have any of the following problems, it is possible that your doctor will not recommend eye surgery for you. Keep in mind that people who are carefully examined before surgery generally get the best results from laser eye surgery.


Autoimmune disorders such as rheumatoid arthritis

Weakness of the immune system due to the use of immunosuppressive drugs or HIV disease

Persistent dry eyes

Changes in vision due to medication use, hormonal changes, pregnancy, breastfeeding, or aging

Corneal inflammation, eye injuries or diseases

Simple herpes that affects the eye area.

important points:


On the day before and on the day of eye laser surgery, avoid eye make-up and use creams and perfumes.

If you wear contact lenses, you should replace them with glasses a few weeks before the procedure.

Depending on the duration of lens use, the doctor will provide specific instructions. During the initial examination, the doctor will ask about your medical records and check for symptoms such as infection, inflammation, and dry eyes.

Care after eye LASIK operation


Immediately after the procedure, you may feel itching or burning. Your vision will probably be a little blurry and you will experience some pain. The doctor prescribes painkillers and eye drops. Some doctors ask the patient to wear eye protection during the first few nights of sleep.


After surgery, it takes some time for vision to return to normal. Two to three months after the operation, it is completely recovered and vision is stabilized. Usually, 2 days after the surgery, the doctor arranges an examination to observe the healing process and complications of the operation. In the first 6 months after surgery, you will have appointments with an ophthalmologist.


In the first few weeks, you should not use cosmetics around the eyes. You should wait a few weeks for sports like swimming. Be sure to take the doctor’s recommendations seriously during this time and follow them all.

Advantages of eye LASIK


Eye LASIK is one of the most popular methods to fix eye defects. Many people do this every year. The benefits of laser eye surgery are many. Some of these benefits include:


Rapid improvement of vision

Relatively painless

High patient satisfaction in the long term

Disadvantages and possible side effects of eye LASIK


Complications such as loss of vision in laser eye surgery are very rare. But side effects such as dry eyes and temporary vision problems are relatively common. These side effects usually go away after a few weeks or months. Very few people have these problems permanently. The risks and side effects of LASIK are:


Dry eye: Laser eye surgery temporarily reduces tear production. In the first 6 months after surgery, this complication may exist. Dry eye can affect the quality of vision. Usually, the ophthalmologist prescribes eye drops for dry eyes.


Light sensitivity and double vision: You may have trouble seeing at night for a few days to a few weeks after surgery. Increased sensitivity to light and creating a halo around the lights, double vision is also created during this period.


Incorrect corrections: This condition occurs mostly in myopic people. This complication occurs when the laser removes too little tissue from the eyes. In this case, it may be necessary to operate again.


Overcorrection: In this case, the laser removes too much tissue from the eye. In this case, it is very difficult to solve the problem.


Flap problems: Removing the flap from the front of the eye during surgery can cause complications such as infection and excessive tears. The outermost layer of corneal tissue may grow abnormally under the flap during healing.


Return to the previous state: sometimes, vision may return to the state before the operation. Of course, this complication is not very common.


Loss of vision: The probability of developing this complication is very low. But sometimes, a person may lose his sight or not see the past clearly.


Due to the possibility of such complications in laser eye surgery, you must choose a licensed and experienced eye surgeon. High experience in eye LASIK operation can minimize its complications.

3- What is the cost of LASIK eye surgery?

The cost of eye LASIK depends on various factors. Doctors offer different prices according to the level of experience and the team of assistants. In addition to the cost of the surgery and the salary of the surgeon’s assistants, you should consider other costs such as the cost of the eye examination and evaluation session and estimate the price of eye laser according to these items.

Eye laser operation is not a necessary operation and people only use this method to get rid of glasses or lenses. Therefore, health insurance usually does not cover its cost. You should keep this in mind when calculating the cost of surgery.

4-Is it possible to use medical lenses before eye LASIK?

Depending on how long you have been using the lenses, your doctor will give you recommendations. It is usually necessary to stop using contact lenses a few weeks before the operation and use glasses instead. Lenses change the natural shape of the cornea. This can lead to incorrect measurement of the cornea and unfavorable surgical outcome.

After the LASIK eye surgery, you should avoid strong light for a few weeks. In this situation, the doctor suggests using tinted glasses. In rhinoplasty, the use of glasses is prohibited for several months due to the weight on the nose. For this reason, doing these two actions at the same time can cause problems. If you intend to perform two eye and nose surgeries at the same time, be sure to consult with both specialist doctors and act according to their opinion.


9- How to find the best eye surgeon for LASIK eye surgery?

Most people are not familiar with doctors when choosing the best eye LASIK doctor. When choosing an eye specialist, you should ask about previous patients or your friends.
