The procedure involves an excimer laser used to reshape your cornea to correct the imperfections in your cornea. Essentially in such cases:
- Advanced astigmatism
- Corneal abberations (An aberration is a distortion acquired by a wavefront of light when it passes through an eye with irregularities of its refractive components)
- Still having vision problems after previous Lasik procedure
- Previous cataract or cornea surgeries
i-Lasik in astigmatism treatment
Standard LASIK treatment in advanced astigmatism and corneal aberrations may cause a loss of vision quality after the procedure.
Nowadays, thanks to Wavefront technology, it is possible to analyze these aberrations and transmit all the analysis details into the laser device.
In this way with i-LASIK, it is possible to treath both vision problems such as asgitmatism and corneal aberration or general vision quality.
Wavefront is a custom(individualized) treatment technique that aims to increase the vision quality better than a standard laser treatment. Certain light waves are sent to the eye and they reflect from retina. With this reflection the treatment can be planned. In this way your eye can be analyzed as a whole in order to detect if there is any other elements that may cause a loss of vision besides myopia, hypermetropia and astigmatism. It allows us to fix “hidden” problems that can not be detected with standard laser treatment.
Re-shaping the cornea in order to eliminate all the corneal aberrations allow the patient to have a better resolution and better sense of contrast. In this way the patient can have the “maximum performance” from his/her eyes.
i-Lasik treatment is the same as a standard LASIK treatment with all its pre and post operation stages.
After an i-Lasik treatment, results below +/- 0,50 are considered as successful and the patient does not need to wear glasses anymore.
Am I suitable for i-Lasik?
Those who are above the age of 18 and have not experienced a change of eye prescription are candidates for i-Lasik. However, in order to make sure, it is recommended to have a full examination by your doctor to see if you can have it.
For an eye laser treatment, it is important to evaluate the thickness, curve and biomechanical strength of cornea and to examine to see if there is any additional vision disorders such as keratoconus, cataract or dry eye. Also, it is very important to see if there is strabismus or any damage in retina which may be an obstacle for the operation.
In order to perform an i-Lasik treatment, the visual acuity numbers should be below +10,0 for Myopia, +6,0 for Astigmatism and -6,0 for Hypermetropia.
Who can not have an i-Lasik treatment?
- Those who have corneal disorders such as keratoconus, corneal dystrophy (genetic disorder in which abnormal material often accumulates in cornea) etc.
- Those who do not have the enough thickness of corneal tissue
- Those who have advanced dry eye
- Those who have glaucoma
Before and after i-Lasik treatment
Before the procedure, the patient should not put any make-up on.
Since it is performed under topical anesthesia (analgesic eye drop), patient can eat before and after the procedure.
It is recommended to stop using hard contact lenses 2 weeks before, and soft lenses 1 week before the procedure. If there is any general discomfort in eyes, the doctor should be informed beforehand.
The procedure takes nearly 10-15 minutes. After the procedure it is normal to feel burning, watering, aching and to have a blurry vision. You should use the protective glasses and eye drops that will be prescribed by us. The day after the procedure we will perform a check-up and then you will be able to return home.
