What exact is laser eye surgery?
Laser eye surgeries are performed to eliminate myopia, hyperopia, astigmatism, and keratoconus problems under appropriate conditions.
Laser eye surgery, which can be used for these and many other reasons, is performed after various examination procedures with medical advice.
Some of the issues to consider here are the suitability of the patient’s corneal thickness and shape for the treatment.
In addition, the patient’s age, medical history, and number of visual defects are important in determining whether or not they are suitable for the surgery.
During the procedure, the patient will be asked to look steadily at a specific point and an eye drawing operation will be performed by sending a laser beam to a specific area on the outer surface of the cornea. Laser eye surgery, also known as eye drawing among humans, is essentially the reshaping of the cornea, the transparent layer that filters the light with the help of laser beams, and eliminates myopia, astigmatism and hyperopia problems in certain diseases. Thus, the patient offers a clear view and correct focus.
Is it right for me? Am I eligible?
- It can be used from 18 years of age. Since development is not complete by this age, there is a possibility that the eye disease may increase. Therefore, people under the age of 18 are not suitable for the operation.
- It can be used on patients with an appropriate corneal thickness. In contrast to LASIK and iLASIK laser applications, no touch laser application can also be used on patients with a thin corneal structure.
- It can also be used on people who have previously undergone cataract surgery and whose retina has torn, if the appropriate conditions are met.
- It can also be used in patients with moderate astigmatism and hypermetropia and in high numbers of myopic patients.
- It can be used on patients who have various scars and spots on the corneal layer.
Different types of Laser Eye Treatment
Laser eye treatment is implemented using 3 different methodologies. All of which are painless, reliable and are internationally recognized. While all patients need to get their eyes examined by a professional beforehand, this should give you a general idea of what’s in-store for you.
LASIK
The Lasik method is an extremely reliable method that has been used for years. It starts with numbing the eye tissue with anesthetic drops. In this way, the patient does not feel anything during the operation. Then a flap is removed from the cornea with a so-called microkeratome (with the Lasik method, this flap is also opened with a laser). The corneal flap is folded back and removed from the area where the laser is being used. Excimer laser beams are directed onto the tissue under the removed part. The LASIK method is a suitable method for eliminating myopia and hyperopia problems. The patient does not feel any pain during the application. Eyesight improvement begins within 3-5 days and gives satisfactory results.
iLASIK – Intralase-LASIK
The iLASIK method is carried out with Wavefront technology and Intralase, i.e. a bladeless method. In addition to treating visual disorders such as myopia, astigmatism and hyperopia, this method is also used in preparing the appropriate canal for the rings in the treatment of keratoconus and in the application of keratoplasty. The incision required for LASIK is made using a computer system with controlled femtosecond beams. With the wavefront technology used in the iLASIK procedure, it is possible to image the patient’s cornea. In this way, a personalized treatment can be carried out.
Laser treatments, other than those used to correct vision problems, are used to remove dry eyes, glaucoma, and retinal vascular problems. These are applications that are usually carried out in the practice environment and at the patient chair. They are not in the nature of an operation, but in the nature of outpatient treatment.
TranskPRK – Contactless Laser
The no touch laser can be used for patients with distance and near vision problems. The procedure, which is initiated by dropping anesthetic drops into the eye, takes between 50 seconds and 1 minute. There is no eye contact during the procedure. In addition, it can be used on people who have undergone cataract surgery prior to the no-touch laser procedure and whose retina is prone to tears if the conditions are right. Finally, it is possible to use the no-touch procedure on patients with thin corneas and steep angles. The no-touch laser procedure is non-contact, so it does not have the characteristics of an operation.
What should be considered before the operation?
Before undergoing laser eye surgery (eye drawing), the patient should not apply make-up or perfume in the eye area. In addition, blood thinners should not be used on the day of surgery.
Contact lens wearers should stop using contact lenses for a few days before surgery. If there are other problems that require special attention to the patient’s condition, the doctor will advise the patient of what to do in the preoperative preparation phase.
How is laser eye surgery performed?
Although there are different uses for No Touch Lasers, LASIK, and iLASIK, the general procedure is as follows:
- The patient enters the operating area and is allowed to lie on his back on the laser bed.
- The patient’s eye area is covered with a sterile cloth, one eye remaining open.
- The eye is numbed with the drop anesthesia method. The patient does not feel any pain during the procedure.
- If necessary, the patient may be given sedatives to avoid agitation during the procedure.
- The area around the eyes, numbed by drops, is thoroughly cleaned.
- It can be used in two different eyes in one day.
- A retractor is placed to keep the eyelid open during the operation and thus the operation is started.
The workflow differs for each type of treatment after the initial phase.
With the no-touch laser application, the laser treatment (eye drawing) is applied to the corneal area of the patient for 50 seconds and one minute without eye contact.
With the LASIK method, a corneal flap is created using a microkeratome. After the corneal vein is formed, laser eye surgery is performed under the removed part.
With the ILASIK method, the incision required for the LASIK is created with a computer system. Then laser beams are sent to the cornea and the treatment is carried out.
The patient is observed for about half an hour after the operation. Depending on the type of operation performed, blurred vision and a burning sensation may occur in the first few days; hospitalization is not required after the operation. Patients are discharged immediately within a few hours.
Things to consider before your operation
- Doctor-administered drops and medication should be used with caution.
- It is necessary to take care of the eye for a week and not rub it with hard movements.
- During the first month, sporting activities should be carried out with protective goggles.
- Water should not touch the eyes for a few days after the operation.
- It should be protected from UV light as much as possible, and sunglasses should be used in bright daylight.
- The vehicle should not be used immediately after the operation.
- strenuous work should be avoided in the first week.
- Regular checkups determined by the doctor should not be interrupted.
