What are the advantages and disadvantages of the diffractive multifocal IOL?
The diffractive multifocal lens implant provides excellent reading vision and very good distance vision. The intermediate vision is acceptable but some patients who do lots of computer work find they need to sit closer to the computer, make the font size larger on the screen, or get a pair of intermediate vision spectacles to make intermediate work more comfortable. In addition, 25% of patients note glare and haloes around lights at night with the diffractive multifocal IOL, 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 7-8% of patients implanted with monofocal lenses also notice glare and halos.
