Some may think that a segment bifocal IOL would have no sacrifices in visual quality compared to a bifocal (or trifocal) IOL with diffractive light-splitting rings. Well, that’s not really the case because there is still no way of cheating physics. In the case shown here, the patient is not happy with night vision with this segment bifocal IOL and our surgeon performs a successful IOL exchange, replacing it with a monofocal IOL. That certainly fixes the night driving issues and the patient is happy. Note that this IOL is not FDA approved and as such, it is not available in the USA (as far as I know).
