As one of the world’s leaders in LASIK laser eye surgery, we are always delighted when people ask us: What is LASIK eye surgery?
One reason for asking is that people worry about what the laser eye surgery procedure is and whether it will hurt or not.
As we have previously explained on the Advanced Vision Care blog, there are lots of benefits to using LASIK laser eye surgery over its predecessor PRK. The procedure is quick; it doesn’t take more than 30 minutes to operate on both eyes and it doesn’t hurt. The recovery time using the LASIK procedure is also quicker.
Having said that, we thought a blog entry which gave more detail about the process used for LASIK eye surgery would be very helpful.
Details of LASIK eye surgery
To begin with we clean and prepare the eye for surgery and use a small device to stop blinking before applying some light suction.
Then the procedure begins and the surgeon will use an IntraLase (blade-free) laser to cut a small flap from the cornea (surface of the eye). This is the part of the procedure which concerns most people and I will give more details further down.
So when the surgeon has opened the flap, (the flap thickness is very thin which enables quick healing of the eye post-surgery), the eye tissue is exposed for reshaping by the laser.
This is the most important part and every operation is geared towards the patient’s own exact requirements by using a computer-controlled laser called the Technolas z100 which is made by Bausch and Lomb and which is the most technically advanced of its kind. This laser has advanced features like iris recognition and 3 dimensional eye tracker, ensuring patients need not worry about eye movements during the procedure.
Using this laser, the surgeon then shapes the corneal tissue to get the optimal results for the patient.
The corneal flap is then put back into place and a protective soft contact lens is placed on the eye for up to 48 hours and this will be removed during the first after-care appointment.
Blade-free laser eye surgery
It’s important to stress that here at Advanced Vision Care we use only the latest and very best equipment available. This extends to our use of the IntraLase LASIK laser for eye surgery and we do so for several, very good reasons.
Using this blade-free technology brings superior quality vision and a quicker healing and recovery time. There is also reduced night-time glare and this process usually reduces the risk of any complications arising from the procedure. This is the gold standard and norm everywhere and patients should ask about this when they go for any laser consultation.
This is probably a good time to highlight the use of wavefront technology and this is something that everybody researching laser eye surgery will come across.
Essentially, the term wavefront refers to the technology being used to cater specifically for a patient’s eye rather than having a one-size-fits-all approach to laser eye surgery. More importantly, this means that the surgeon is working to the exact specifications of your eye to bring you the very best results possible.
However, there are varying levels of wavefront technology being used and caution should be exercised when you are dealing with a surgery that uses a cheaper version wave front optimised which does not correct the imperfections .
We use the latest advanced wavefront technology to create a 3-D map of the cornea’s rear and front. It is this map that will reveal to the surgeon whether the eye is not only healthy but also suitable for laser eye surgery.
