Ultrasonic cleaning for disposable contact lenses: good idea or not?

This goes for about $15 (plus shipping).

Ultrasonic cleaning got my lenses feeling like new. I recommend it. I am still wearing the same "disposable" lenses after two years.

Looks reasonable to me. Ultrasound is quite safe, and will help dislodge tiny particles that might not come off in normal washing.

meh, for the few cleanings you should give them prior to disposal won't your fingers suffice? Ultrasonics are good for things you can't reach like crevices. A big flat lens surface - who needs it, unless you are too lazy to put it between your fingers for a good rub.

As I understand it, protein eventually binds to the 'plastic' of disposable contact lenses, which is why we have to dispose of them. These enzyme removing cleaners help for a while, but do not prevent protein binding. This is not precisely my field, but I am not certain how ultrasonics will break these bonds, and I am unable to find a scientific study that evaluates these claims.

Personally, I think you only get one set of eyes, why take the chance?

The disposable contact lenses are exactly the same as doctors used to prescribe a single pair for wearing every day for a year -- maybe slightly thinner. There's no reason not to clean them thoroughly and continue wearing them.

Response by poster: Two month update... I've had a LensoClean for about two months now, and... underwhelmed. The extra handling that the lenses get going into and out of the basket holder, combined with the unhygienic recommendation by the manufacturer not to wash the device are weak points IMO. The results achieved reflect the lack of power of the device (~8W) versus higher powered light industrial devices.
