Cataracts are a clouding of the natural lens of the eye, which occurs in everyone at some point in their lives. When this clouding interferes with the quality of vision and begins to affect your daily activities, cataract removal is indicated.
When the cataract is removed we are removing the lens of your eye. We always replace the cloudy lens with a new lens implant known as an intraocular lens (IOL). There are now more choices in lens implant options, and these new IOLs can greatly decrease dependency on the need for glasses after surgery. In some cases, the premium IOL will eliminate the need for glasses all together.
Following surgery with a traditional IOL, patients often still need to use their reading glasses, bifocals, trifocals, or progressives lenses to be able to read objects at close range. This is because traditional IOLs implanted during cataract surgery typically only correct for distance vision. There are a variety of IOLs that can be used in cataract surgery, and they each have their own set of advantages. No single IOL works best for everyone, and only your ophthalmologist can determine the most appropriate IOL for your visual needs. The most effective lens depends on each patient’s individual preferences and goals for their vision.

In the past, intraocular lenses were only able to correct distance vision, often leaving patients with the need for reading glasses. Multifocal IOLs offer patients a decrease in dependency from glasses after cataract surgery by improving vision at all distances. These lenses can change focus to accommodate your vision needs. Up to 80 percent of patients do not need to rely on glasses after multifocal IOL implantation. The AcrySof ReSTOR IOL utilizes diffraction optics to provide excellent visual acuity at near and distance. The Tecnis Multifocal lens has multifocal zones that provide a range of visual correction and thus provide good vision over varying distances.
Many people experience a loss of near vision with age and often need to rely on glasses after cataract surgery. Accommodative IOLs such as Crystalens replace the eye’s natural lens and mimics its accommodation capabilities, allowing you to see clearly across a wide range of distances. The Bausch and Lomb Crystalens has the ability to accommodate or alter shapes, thus allowing your eye to focus on both distance or near objects.
Toric IOLs are specifically designed for patients with astigmatism. In the past, patients with astigmatism would need eyeglasses or contact lenses even after cataract surgery in order to see clearly for distance vision. Toric IOLs such as AcrySof Toric correct cataracts and astigmatism with just one lens, providing a more convenient and affordable solution to your vision needs. This unique lens allows us to reduce or eliminate corneal astigmatism, thus reducing the need for eyeglass correction for best distance vision after surgery. If you have a history of astigmatism Dr. Allaman may recommend this new surgical product.
Dr. Allaman and his staff will be happy to discuss any of the new lens implant products available.
