Question: I had LASIK surgery over 15 years ago. I have been told by an ophthalmologist that multifocal cataract lens implants may create halos around lights. Have you heard of this? If so, how often and how bad can it be?
Answer: Multifocal Lens Implants are very complex optical designs of several types. Indeed depending on the optical design some do in fact cause haloes, the degree to which they cause haloes depends n the design, the pupil size, aberrations and other factors. However, it is possible that one of the designs may be of minimal if any problem for you. If you are wishing to consider a multifocal lens implant your cataract surgeon advises against it you may wish to get a second opinion and even a third as different surgeons may not be experienced with each and every lens implant design type. Then, you can make an informed decision
