Lasik is an extremely reliable method that has been used for years in laser eye surgery. The method starts with numbing the eye with anaesthetic eye drops. Then, corneal layer is removed by a special tool which is called microkeratome. This process is called corneal flap creation.
The corneal flap is carefully folded backwards away from the area where the laser will be applied. Laser rays (beams) are sent to the tissue under the removed part with excimer laser.
Lasik is an appropriate method of laser eye surgery to correct myopia and hyperopia. The patient doesn’t feel any pain during the laser vision correction. A patient obtains a good level of vision within 3-5 days.
iLASIK (Intralase LASIK)
Wavefront technology and intralase (bladeless method) are used in iLasik method. This laser eye surgery is performed to correct myopia, hypermetropia and astigmatism as well as in the process of corneal ring implantaton and keratoplasty (corneal transplantation).
The cut required for iLASIK is controlled by femtosecond laser beams with the help of a computer system. In the iLASIK method it is possible to create a map of cornea with Wavefront technology. Thus, individualized treatment can be applied in laser eye surgery.
Laser can be used not only to correct vision but also to treat such diseases as: dry eye syndrome, elevated eye pressure (IOP- intraocular pressure), retinal vascular disorders. These applications are usually made in the patient chair at a doctor’s room. The most common of these treatments are:
• IRPL Treatment – For Dry Eye Syndrome
• SLT Treatment – For Elevated Eye Pressure
• YAG Laser
• Argon Laser
LASER EYE SURGERY
No Touch Laser (Trans PRK)
No Touch Laser can be applied to patients who have near and distance vision problems. The procedure starts with applying numbing (anaesthetic) eye drops and the process lasts from 50 seconds to 1 minute. There is no contact with the eyes by surgical instruments during the operation. In addition, the laser eye surgery can be applied to people who had cataract surgery or whose retina is prone to tears. (*upon eye tests being appropriate. ) Finally, laser eye surgery is also possible for patients with thin or steep corneas. (Ps: No Touch Laser procedure is performed without touching the eye, it does not have the characteristics of an eye surgery, so, we do not call this process a ‘surgery’)
The advantages of the No Touch Laser are as follows:
• During the eye laser surgery, there is no sharp tool or device touching the eye.
• The laser vision correction for both eyes is be completed in a single session.
• After the laser vision correction, your eyes will not be covered and you will be discharged with protective glasses.
• It can also be applied to patients with thin corneal structure.
• The laser vision correction is used to treat patients with myopia, hyperopia and astigmatism.
• There is no removal of any corneal layers.
• The possibility of dry eye syndrome is minimal at the end of the procedure, the reason is that there is no contact with eyes.
• According to corneal topography test results, laser vision correction can also be applied for patients with high refractive errors.
IRPL (Intense Regulated Pulsed Light Therapy)
Intense regulated pulsed light (IRPL) therapy is a relatively new dry eye treatment. It’s particularly effective in treating meibomian gland dysfunction (MGD), the most common cause of chronic dry eye.
IRPL targets all aspects of meibomian gland dysfunction by:
Improving meibomian gland function
Unclogging meibomian glands
Improving tear film quality and stability by restoring the lipid (oil) layer of the tear film
It is also one of the only treatments that can help potentially regenerate meibomian gland structure.
This treatment is both efficient and effective, making it a promising treatment for persistent dry eyes.
SLT (Selective Laser Trabeculoplasty)
Selective Laser Trabeculoplasty, or SLT, is a form of laser surgery that is used to lower intraocular pressure in glaucoma.
It is used when eye drop medications are not lowering the eye pressure enough or are causing significant side effects. It can also be used as initial treatment in glaucoma. SLT has been in use for more than 25 years in around the world.
A YAG laser can be used to treat several types of vision problems. Examples include sealing leaking blood vessels, reducing pressure in the eye, replacing the cornea, and removing part of the iris.
The most common procedure is a capsulotomy after cataract surgery. This procedure is used when clouding develops behind the lens placed after cataract removal. The laser creates a small hole behind the lens that light can pass through.

What are the risks of laser eye surgery?
There are risks with any surgery. According to the Royal College of Ophthalmologists, complications occur in less than 5 per cent of cases, but make sure your consultant outlines all the risks. Flap complications with LASIK arise in 0-4 per cent of cases, but can usually be corrected with little or no loss of vision. Some people have a problem with dry eyes in the months after surgery and artificial tear supplements may be needed long term. Many patients have experienced glare or halo effects when night driving, particularly just after treatment. This is more likely the higher the correction that has been made, but is rarely severe. In rare cases, excessive thinning of the eye wall can cause the shape of the eye to be unstable after treatment. Severe loss of vision is very unusual, but some patients could require corneal surgery or hard contact lenses to restore vision. You should find out exactly how frequently your surgeon has experienced complications and why.
Who can have laser surgery?
You need to be 21 or over to have laser surgery, with stable vision, so the surgeon knows that your eyes are less likely to change due to growth. Your eyes must be healthy, and the consultant will assess if your cornea is thick enough for the surgery. Some people with high
prescriptions may not be suitable. You need to be in good health too. Ask your consultant for further discussion of whether you are a good candidate for the procedure.
