Multifocal Lens Implant Choices

Question: The AcrySof® ReSTOR® Multifocal Lens Implant has been recommended to my husband who is in need of cataract surgery.  He received little information from the cataract surgeon about this lens other than he only offered the ReSTOR® Multifocal Lens Implant or the basic replacement lens implant.  After doing some research we think the ReSTOR® might be the best choice but we are concerned about the reports of halo or glare experienced during night vision since he drives often at night.  I don’t know that all the all the information we have found is very current so we are wondering if the halo/glare is still an issue with this particular lens? He is interested in not having to wear glasses but being able to drive at night is a must.

Answer:  All Multifocal Lens Implants are complex optical designs that utilize various types of refractive, diffractive or combination optics to achieve their effect. These optical designs ALL can cause some degree of glare and halo-or night photic disturbances. Further these night vision problems can actually be exacerbated without exquisitely precise surgical technique and implantation as their centration and positioning is critical. Also, some designs can cause a greater or lesser amount of night vision disturbance depending on pupil size. That said, in general the AcrySof® ReSTOR® Multifocal Lens Implant tends to cause a lesser degree of night vision problems when optimally implanted in patients with appropriately sized pupils-BUT still all patients should be aware of the  possibility of night vision problems. As you are raising a valid question and concern it might be wise to seek a second opinion by finding the best cataract surgeon in your area who uses multiple multifocal and accommodating near vision lens implant technology platforms in order to have the best and most broad based evaluation.
