Difference between KAMRA and PRESBIA

As the natural lens ages, its ability to ‘accommodate’- that is, to alter shape to provide focus on objects at all distances- begins to fail. Laser Eye Surgery can restore some of the functions of our natural lens, and now there are options for correction of Presbyopia.
 
Corneal Inlays will fix your Focus
 
Presbyopia affects all of us after a certain age; the aging of the lens is inevitable and many of us have trouble focusing on near objects. Corneal Inlays are an extremely effective way to restore the abilities of focus to your ageing eyes.
 
Kamra and Presbia Flexivue Microlens are both types of corneal inlay, each doing something slightly different. Inlays are typically inserted into a tiny corneal pocket, and they improve near vision by creating a central myopic area (Presbia) or increasing the depth of focus (Kamra).
 
How Corneal Inlays Work
 
Each has a different mechanism of action, and each gets implanted into the non-dominant eye-you only need to have one inlay implanted.
They both work slightly differently-the Kamra increases the depth of focus through a sort of pinhole, like the zoom feature on a camera.
The Flexivue Microlens changes the central refractive index in the eye and focuses image properly on the retina.
A femtosecond laser is used by the Optilase Ophthalmic surgeon in each case; he can create a tiny little flap or pocket and slip the corneal inlay neatly into place.
 
Easier Life with Corneal Inlay
 
Inlays are great for presbyopes (people with presbyopia) of pre-cataract age; usually in your 40s. They are so very tiny that they’re really more or less invisible to the naked eye-and remember, you will only have one inlay in one eye.
 
The difference a corneal inlay like the Flexivue Microlens can make is really quite astounding; near vision is instantly improved as correct focus is restored. As distance vision isn’t impacted at all, the procedure is great for those whose distance vision is just fine but who have to wear reading glasses for close work.

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.
