Until recently cataract patients received monofocal lens implants that had only a single power. This meant you had a choice of correction for either far or near vision. If you suffer from presbyopia like many people over the age 50 this would mean that you still need glasses for either reading or for distance vision. The FDA has now approved several multifocal lens implants for use by certified ophthalmologists. The multifocal IOL lens can increase your chances for a life free of dependence on glasses or contacts after cataract surgery for near, far, and intermediate vision. If you have worn glasses for 30 years this might be an opportunity for you to eliminate this hassle from your life.
The implantation procedure is the same for both types of IOLs. The main point of differentiation between the IOLs is in the type of vision they provide.
