Question:
Hi, I’m italian and I have keratoconus. I’m extremly interested in synergeyes lenses because I pratice agonistic sport and I need a stable, soft-like lens.
Here in Italy synergeyes aren’t yet avabile, and would be avaiable in 2008 at best.
I have a friend with a brother in the USA … Is it possibile having the right prescription from an eye doctor to get these lenses in the USA through my friend’s brother or is just too dangerous ?
Answer:
Unfortunately, this would be way too dangerous and unpredictable. As I am sure you know from your past lens experience, fitting a contact lens on keratoconus can be a challenge in and of itself. The same goes for fitting synergeyes. While they are great and promising lenses, they absolutely need to be fit, especially with keratoconus.

I also like to stress that the synergeyes hybrid contact lens does not work for every eye. With keratoconus, it works best for central to inferior central cones. If your keratoconus is more inferior, or is actually pellucid marginal degeneration, synergeyes will not work as well.
If you are in a truly dire situation, and you really want to try the synergeyes, you can always take a trip to the states and visit your friend. Depending on the final lens needed, some synergeyes may take a couple weeks to manufacture. however, If you fall in to their "stock" parameters, lenses can be available for immediate shipment.
Another alternative you may want to consider in Italy is a piggyback lens system. Think of this as your eye care provider manufacturing their own hybrid contact lens. We usually use a high oxygen permeable silicone hydrogel soft lens like the Ciba Night and Day or Acuvue Oasys as a base lens. The soft lens only acts as a cushion and provides no visual effect. On top of the soft lens, a high oxygen permeable GP lens is fit.
The combination leaves you with comfortable, stable vision. Great for sports because the lenses should be stable and nothing will get under them.
You may also consider a semi-scleral gas permeable lens. These are gas permeable lenses that are the size of soft lenses. When fit properly, semi-scleral contact lenses are incredibly comfortable and also great for sports.

In short, even though the synergeyes is not yet available in your area, don’t worry. You still have plenty of viable contact lens solutions to correct your keratoconus so you can play sports. And when you can evaluate a synergeyes, check them out.
I have seen mirrored contact lenses in the movies. I think Vin Diesel wore them in Riddick. Are mirrored lenses available to the public? And if so, where can I get some? Read the rest of this entry »
I was wondering if there is any Bifocal Contact Lens that can be worn for a week or two? My eye doctor said that there is not. But a friend of mine said that there was. Please help, not sure if I need to find another doctor or not. Read the rest of this entry »
