Anyone here go through it or know much about it?
Have a family member and a friend who both will have to go through it soon.
Attend to what Nadir wrote. I second it 100 percent.
Have to make a decision whether to go for monofocal or multifocal (expensive and riskier) lenses.
Monofocal is my advice. Among many other reasons, there is the fact that the choice of multifocals will inevitably leave you feeling much older (don't laugh! the psychological impact is genuine and far-reaching).
Far better still would be to ditch the lenses and revert to specs unless the weakness in your left eye differs markedly from that in your right.
