Eye laser treatment with excimer laser and answers to your questions

What is Refractive Surgery?

Refractive surgery, popularly known as eye drawing, is an eye laser surgery that allows focusing the image on the retina by changing the refractive power of the cornea. It is used to treat myopia, hyperopia and astigmatism with eye laser surgery. There are many different forms applied today and the most frequently applied method is Lasik surgery. Apart from this, refractive surgery is performed with many different methods such as LASEK, NO TOUCH LASER, WF LASIK, İ-LASIK, SMİLE.

Is Excimer Eye Laser Surgery a Reliable Surgery?

Excimer laser surgery was approved by the US Food and Drug Administration (FDA) 20 years ago. Since then, the benefits and risks of laser have been extensively studied. More than 600 peer-reviewed studies have shown that an average of 95 percent of patients are satisfied with the results after LASER surgery. Studies have shown that the latest technology new lasers significantly reduce the undesirable side effects, which we will talk about later in this article, compared to the old generation lasers.

Who is a good candidate for Excimer Eye Laser Surgery?

To have laser surgery, you must meet certain conditions. Some of those:

You must be 18 years of age or older (ideally, over 20, when vision changes are more likely to stop).

Your eye degree should not have changed 0.50 diopters or more in the last 1 year

The cause of the low vision must be due to a disorder to be corrected with laser, that is, there should be no other disease causing the low vision in the eye.

The cornea needs to be thick and healthy enough, and your overall eye health should be good overall.

You need to have realistic expectations in terms of vision expectation after laser.

Who is not a good candidate for Excimer Eye Laser Surgery?

People with constantly changing eye numbers

Extreme levels of myopia (12 D and above), hyperopia (6 D and above), or astigmatism (6 D and above)

severe dry eye

very thin corneas

Corneal spots or diseases

Keratoconus

advanced glaucoma

cataract affecting vision

uncontrolled diabetes

pregnant or breastfeeding women

What to Expect Before Excimer Eye Laser Surgery?

After deciding on laser surgery, you need to undergo a detailed eye examination. The most important stage of laser surgery is the preoperative evaluation. During the examination, you should discuss with your doctor about the operation process and your expectations after the operation. A detailed eye examination will be done before the surgery.

A vision test will be done. The presence of any eye disease that will cause visual impairment, other than refractive error, will be examined.

Your eye degree will be measured. According to your last examination, it will be checked whether your eye degree is different. After the normal eye degree measurement, drops will be placed in your eye and your eye degree will be measured again.

The presence of other eye problems will be checked. It will be checked whether there is an eye disease that interferes with the laser.

Corneal mapping and corneal thickness will be examined by corneal topography. .

Pupil size will be measured.

If your eye is completely suitable for the laser after the entire examination, you can get laser approval. You and your doctor can discuss and decide which method would be better for you.

What Awaits You During Laser Eye Surgery? What are the Types of Laser Surgery?

Laser surgery is done on an outpatient basis and does not require hospitalization. Your laser procedure will be applied within an average of 1 hour after you go to the clinic on the day of surgery. The laser process takes an average of 10-15 minutes. You will be discharged after resting for half an hour after the surgery.

Lasik

Your eye is numbed with drops.

Your eye surgeon will first cover your eye with a sterile drape. An eyelid holder is then placed on your eye to prevent blinking.

A vacuum ring is placed in your eye to prevent eye movement. You feel pressure like a finger pressing firmly on your eyelid. At this point your vision darkens. Your ophthalmologist creates a paper-thin flap of corneal tissue using a microkeratome or an intralase laser device. This process takes an average of 30 seconds.

The flap is then lifted and folded back.

In the next step, you will be asked to look at a target light with your eyes. While you are looking at the target light, the ophthalmologist reshapes your cornea using a special laser programmed specifically for you, based on measurements made into your eye.

After reshaping the cornea, your eye surgeon folds the flap back into place and flattens the edges. The flap adheres spontaneously within 2-3 minutes. And the operation is over. The same operations are then done for the other eye.

No Touch Laser

Your eye is numbed with drops.

Your eye surgeon will first cover your eye with a sterile drape. An eyelid holder is then placed on your eye to prevent blinking.

It is a surgical laser procedure performed without flap lifting.

You will be asked to look at a target light with only your eyes. While you are looking at the target light, the ophthalmologist reshapes your cornea using a special laser programmed specifically for you, based on measurements made into your eye.

After the cornea is reshaped, the eye surface is washed and cleaned. And the operation is over. The same operations are then done for the other eye.

smile

Your eye is numbed with drops.

Your eye surgeon will first cover your eye with a sterile drape. An eyelid holder is then placed on your eye to prevent blinking.

A vacuum ring is placed in your eye to prevent eye movement. You feel pressure like a finger pressing firmly on your eyelid. At this point your vision darkens. At this stage, the smile device uses laser beams to create a piece called lenticule in the cornea. This process takes an average of 30 seconds.

Then, the lenticule formed in the cornea through an incision of approximately 2 mm is removed by the ophthalmologist.

And the operation is over. The same operations are then done for the other eye.

Lasek

Your eye is numbed with drops.

Your eye surgeon will first cover your eye with a sterile drape. An eyelid holder is then placed on your eye to prevent blinking.

It is a surgical laser procedure performed without flap lifting. Instead, the epithelium that covers the corneal surface of the eye is peeled off by your ophthalmologist.

You will be asked to look at a target light with only your eyes. While you are looking at the target light, the ophthalmologist reshapes your cornea using a special laser programmed specifically for you, based on measurements made into your eye.

Answers to Your Questions

Will there be pain after laser eye surgery?

In laser surgeries performed with Lasik and smile, you will not have any pain during or after the surgery. In laser surgeries performed with No touch, PRK and Lasek, you will have pain, especially for the first 24 hours.

Will my eyes remain closed after laser eye surgery?

Your eyes are not closed after the surgery. Only a clear, ungraded protective contact lens is placed on your eye. In patients with Lasik, this lens is removed the next day, and 1 week later in other methods.

What should I pay attention to in laser eye surgery?

Do not rub, do not rub, do not scratch your eye

Be sure to use the drops given by your doctor.

Do not wash your face by rubbing too much, do not take a shower or bath for an average of 3 days

Do not be in very dusty and dirty environments for the first 2-3 days.

Does laser eye surgery re-grade?

If laser surgery is performed with the appropriate method after the eye degree has completely stopped, the degree does not usually occur again. In studies conducted all over the world, the probability of relapse has been found to be 2-3% on average.

Does laser eye surgery interfere with other eye surgery?

Laser surgery is definitely not an obstacle to another eye surgery. This misinformation among the public is a false information from 20 years ago.

Will it interfere with my daily life after laser eye surgery?

Patients treated with Lasik and Smile can continue their daily lives from the next day. Since the eye recovery takes a little longer in patients who are treated with No touch or Lasek, they can continue their daily work after an average of 1 week.

How much eye drops will I use after laser eye surgery?

You should use drops for an average of 1 month, more than the first week after laser surgery. In the No touch laser, the usage time of this drop can increase to 2-3 months.

Does laser eye surgery cause dry eyes?

After laser surgery, most of the patients experience a temporary dry eye lasting from one week to one month. In 99% of these patients, dry eye disappears within 1 month. Although very rare patients may have complaints of dryness that can last 2-3 months, the possibility of permanent dry eye is low.

How long does it take to heal after laser eye surgery?

Recovery in lasers performed with Lasik and Smile varies between 1-7 days on average. Full recovery in lasers made with No touch and Lasek will take an average of 4-6 weeks. In addition, while recovery is faster in eyes with pure myopia, recovery will take a little longer in patients with hyperopia and astigmatism.

What is the best age for laser eye surgery?

Laser can be done at any age after the age of 18, but the most suitable age for laser is between 18-25 years old.

What are the risks of laser eye surgery?

Like any surgery, laser surgery has risks of problems or complications that you must consider.

Some people experience side effects after laser, which usually disappear over time. However, in rare cases, there are side effects that do not go away.

Other temporary or permanent side effects may include:

eye pain or discomfort

hazy, foggy, or blurred vision

itchy eye

flare

halos (rings) around lights

be sensitive to light

small patches of pink or red blood on the white of the eye that fade over time

Other rare risks include:

eye infection

Worse vision compared to pre-laser: It is a very rare condition and is usually due to reasons such as flap slipping, wrinkling or infection that occur after a difficult operation or especially after surgery.

Insufficient or excessive correction of your vision with the laser: It can be seen especially in devices that work with old technology or in devices that are not regularly maintained.

If I experience laser eye surgery side effects, how long can they take to improve and how can they be treated?

Most of the side effects that occur are temporary conditions that can be treated with medication. Flap complications require immediate treatment and reposition the flap in a short time. In case of excessive or insufficient correction, an average of 3-6 months is expected and laser treatment is applied again.

How much does laser eye surgery cost?

Although the price you will pay in a short time is high, it becomes quite affordable when you consider the costs of glasses and contact lenses in the long run. Although laser surgery fees vary according to the method to be performed for 2021, they vary between 4500 and 10000 TL.

Eagle Eye (Wavefront Guided) What is laser eye surgery?

In wavefront guided laser surgery, the patient’s cornea is mapped in a very detailed three-dimensional manner before the surgery using computer imaging technology. It is used to program the Buharita laser for surgery. Wavefront technology measures and corrects very subtle abnormalities on the corneal surface. Thus, a clearer vision is obtained than with a conventional laser. In addition, the wavefront laser reduces night vision and contrast sensitivity issues.

My eye is not suitable for laser treatment. What are the alternative treatment methods?

Phakic Intraocular Lenses (IOLs)

Phakic IOLs are designed for people with highly refractive errors that cannot be safely corrected with corneal-based refractive surgery. The eye’s natural lens is not removed, so patients can retain their pre-existing focusing ability. During the phakic IOL procedure, your eye doctor places the phakic IOL in front of or behind the iris of the eye. Once the IOL is properly placed inside the eye, it provides the necessary correction to direct the light rays precisely to the retina.

Refraction Lens Replacement (Clear Lens Removal)

With refractive lens replacement (RLE) – also called Clear Lens Extraction or CLE – an artificial lens is used to replace your eye’s natural lens to improve vision. The procedure is very similar to cataract surgery. As in cataract surgery, the patient’s own lens is removed and replaced with multifocal or accommodative intraocular lenses (IOLs). These lenses allow focusing at all distances.
