It used to be that a person treated with cataract surgery would be left with no option but to wear obviously-thick eyeglasses. Advances in the treatment of cataracts and other eye conditions have brought about far better solutions to the problems some people face with their vision. We are pleased to perform cataract surgery using the latest techniques that facilitate depth perception and visual acuity.
Replacement Lenses for Cataract Patients
Instead of placing a non-prescription lens into the eye after cataract removal, today’s eye surgeons are able to restore better vision using precision intraocular lenses. Traditionally, these replacement lenses have restored vision only at a distance, meaning that patients still needed to wear eyeglasses to read or view objects up close. The monofocal lens reflects light to only one point in the eye. Now, we also have the option of multifocal intraocular lenses, which reflect light to more than one point. The precision technique may involve placing one prescription into one eye, and another into the other eye, in order to create better acuity at various distances.
A multifocal lens can be either refractive or diffractive. Each type has unique characteristics that are considered as we evaluate the appropriateness of treatment.
This type of intraocular lens is mathematically formulated to the power that will accommodate intermediate and distance vision. Patients with refractive lenses may still rely on reading glasses in certain types of light. When natural lenses are replaced with refractive lenses, there is a chance that halos or glares will be noticed around light sources. In many instances, as the new lens becomes more familiar, these slight disturbances diminish.
Because the diffractive intraocular lens is formulated to accommodate both near and distance vision, this option makes sense for a large number of patients. Interestingly, the primary limitation of diffractive lenses is that they may not do as good of a job clarifying intermediate vision. So, individuals who work on computers often may find that they need to increase font size or obtain prescription eyeglasses to achieve optimal clarity of objects located within a few feet from their face. Glares and halos may also be noticed with diffractive lenses.
We understand the importance of clear, crisp vision, and we can help you determine which IOL will meet your needs after cataract surgery.
