How does Laser Eye Surgery correct my vision?

It’s understandable that you might be cautious when it comes to using a laser to correct your eyesight, but the simple truth is that Laser Eye Surgery has been in existence in some shape of form since the 1980s.

Laser Eye Surgery technology has seen some massive advances in recent years which has resulted in greater accuracy using a minimally invasive technique.

Optilase Laser Eye Clinics provide the most advanced laser technology to people all over the country, and offer a through consultation process.

Will my entire eye receive laser treatment?

No. The entire Laser Eye Surgery procedure is computer-controlled and only corrects the shape of your cornea at the front of the eye.

And if you were worried about a red-hot laser beam being pointed at your eye, then you’re in for a big relief - the type of laser used during Laser Eye Surgery is known as an Excimer Laser which emits a cool ultraviolet light.

The Excimer Laser has been designed to deliver precise pulses of cool laser light to a specified area and will not enter the back of the eye.

Why is the cornea the target during Laser Eye Surgery?

The human eye needs to bend light that enters through it in order to see objects clearly. This process known as refraction takes place in the cornea and the lens.

Because the cornea is responsible for over 60% of refractive power and refractive errors are typically caused by a misshapen cornea, this is why it is the focal point for Laser Eye Surgery.

What happens to the cornea during Laser Eye Surgery?

Regardless of whether you are shortsighted, longsighted or suffer from astigmatism, the single common thread in each condition is that you have an irregular shaped cornea that prevents you from seeing clearly without the aid of corrective lenses.

During Laser Eye Surgery, tiny amounts of tissue are removed from the cornea using the Excimer Laser. The use of numbing eye drops prior to surgery mean that you will not feel any pain during the procedure.

This creates a cornea that will then be able to bend light correctly, allowing it to focus accurately on the back on the eye, thus creating instant perfect vision.

I had LASIK done in Dublin after a consultation and follow up in Derry. From the very start, Elizabeth in Derry put me at ease with her approach. Such a warm, helpful way about her. Surgeon Mikhall Hernandez took the time to meet me in advance to explain the process. All the staff- Iwona, Julie, Jess, Robbie (from Donegal!) and Rachael, I really appreciated the way they supported me from start to finish

I had a great LASIK experience at Optilase Carrickmines and couldn’t be happier with the results. Dr. Tom Materman is incredibly kind, attentive, and made me feel comfortable throughout the entire process. I highly recommend him, as well as the whole Optilase team! I didn’t feel anything during the procedure, which was much easier than I expected. My recovery has also been going really well—I’m only on day two, and everything has been smooth so far. Thank you to everyone at Optilase for the excellent care!

Life changing. From the initial consultation to the aftercare, Optilase have been friendly, professional and caring every step of the way. No worry or concern was too small for a detailed discussion and helpful response. 3 months after my phakic lens surgery my vision is as good as it ever was with glasses without the hassle. Would recommend the Optilase Carrickmines team to anyone.
