7.Are there any disadvantages of Multifocal
   Intraocular Lenses?

25% of patients note glare and haloes around lights at night with the Multifocal Intraocular Lenses, a feature that is inherent to multifocal lenses. These effects may interfere with your ability to drive comfortably at night. However, most patients find that they get used to this phenomenon with time and the glare and haloes become less obvious. Night driving spectacles may assist in reducing this phenomenon. You should know that approximately 2-5% of patients implanted with monofocal lenses also notice glare and halos.
