What is refractive lens exchange?

Refractive Lens Exchange (RLE) is identical to modern cataract surgery. Both operations involve replacing the natural lens with an intra ocular lens (IOL). The only difference is that cataract surgery is performed mainly to correct blur or light scatter caused by a misty natural lens; whereas RLE is performed to reduce the need for glasses or contact lenses.

IOL implantation is a bit like building your glasses or contact lenses into your eyes.

There are two main types of lens implanted into the eye:
Monofocal IOLs – these lenses have on specific focal point. Most patients target good distance vision and wear reading glasses. This lens can also be set to give good reading vision with the patient wearing distance glasses post-surgery
Multifocal IOLs – Multifocal lenses aim to reduce spectacle dependence for a wider range of activities, including intermediate (computer screens) and near (reading) vision. If you are suitable for Refractive lens exchange, your surgeon will discuss which IOL type is the best option for you.

What are the benefits of refractive lens exchange?
About four out of five patients are completely free of glasses after Refractive Lens Exchange (RLE) with widely used contemporary multifocal Intra ocular lenses (IOLS).

• Clearer vision
• Reduced dependency on glasses
• Free from cataracts, once the procedure is done you never have to worry about cataracts again

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.
