Further to the Reuters reports, this is on the Singapore Department of
Health website

"The Ministry of Health has been actively working with the Health Sciences
Authority (HSA) and the SNEC to investigate the cause of the recent
increased incidence of contact lens related fungal corneal infections.
Our findings thus far, based on the 18 of the 19 cases reported by SNEC (one
patient is currently overseas) are as follows:

 1.. All 18 patients used disposable contact lenses. These lenses ranged
from daily disposable lens to monthly disposable lens and came from a
variety of manufacturers.
 2.. A significant number of patients had a history of poor contact lens
practice. For example 13 of the 18 patients had used expired lenses while 11
wore contact lenses while taking naps.
 3.. All 18 patients reported using Bausch and Lomb's ReNu multipurpose
contact lens solution.
The Ministry of Health strongly advises all contact lens users to practise
proper contact lens care as advised by their contact lens practitioners (key
points to note are located at the Annex below). While the above findings
indicate association rather than causation, in view of the potentially
serious adverse visual consequences of fungal corneal infection, it would be
prudent, as a precautionary measure, for contact lens users to discontinue
using Bausch and Lomb's ReNu multipurpose contact lens solution for the time
being, until the causes behind this recent increase in infections can be
more clearly ascertained. Contact lens users may wish, in the meantime, to
use spectacles instead.

Further investigations are underway to establish the cause of the infection.
We will keep the public informed of any further developments"

Looks like poor patient compliance may have its part to play here. However,
are Singaporeans likely to be less compliant than other lens wearing
populations?

HK and Singapore are both a lot more humid and fungus-friendly than a lot of
the USA and the rest of the world.

I used the 'No-Rub' for quite a while.  I tried the new "moisture-lock" stuff,
which I hate -- for some reason it feels like I have sand in my eyes for the
first 15 minutes after insertion.  I bought some of the Costco Renu-clone,
which immediately felt better.  That means that next time I need it, Costco
will have added moisture-lock to their formulation :-(
