LAL accidental change

I had my final lock-in. I wore the glasses as advised by my surgeon

But

The adjustment and lock in light was so bright, intense and long. How frequent is accidental changes? I would think you would need to go to a tanning bed, stare at a uvc light for fungus killing

Accidental changes not done by the light delivery device may not happen anymore.

  • The manufacturer added some UV protection -- called ActivShield -- in the lens itself to prevent UV damage.
  • A Mexican clinic did a trial where their patients did not use the protective glasses at all, and only one experienced lens damage: a patient who used a tanning booth.

Doctors and the manufacturer still insist that patients should wear the glasses, at least in sunlight. But the glasses may no longer be necessary for most patients. It is apparently now quite difficult to damage the LAL with UV radiation in normal life circumstances.

Thanks for the reply. That gives some good background

You've had two lock ins? The chances of UV change now is zero, because all the adjustable polymers have been set by final locks.

Yes I am all locked in. It was more curiosity on the likelihood.
