Premium Intraocular Lenses
Cataract surgery is an exciting time for patients because it offers the unique opportunity to optimize vision by correcting myopia, hyperopia, astigmatism and presbyopia.
During cataract surgery, the cataract is removed and a permanent intraocular lens (IOL) is implanted in its place. The traditional IOL is monofocal in nature, and it provides the sharpest vision at one distance. These IOL’s only correct for myopia and hyperopia. Patients tend to choose to have the clearest vision at distance and then rely on reading glasses to correct for astigmatism and presbyopia post-operatively.
There have been many advances in the development of special intra-ocular lenses that correct for astigmatism and presbyopia in addition to myopia and hyperopia. These advances have allowed patients to strive for spectacle independence. There are a variety of lens options available; it is important to have a frank discussion with your surgeon to assess your visual needs and expectations.
Toric Lens Implants
The Toric Intraocular Lens (Acrysof IQ Toric IOL) corrects for astigmatism, hyperopia and myopia. Patients have clear vision without glasses at distance and usually require a thin pair of reading glasses for near work.
Presbyopia Correcting Lens Implants
There are two different types of lens implants that correct presbyopia - multifocal and accommodating. Although they represent the most advanced lenses on the market, to date, no lens implant can reproduce both the quality and range of vision you had before the onset of cataracts.
The Acrysof IQ Restor Multifocal lens corrects for presbyopia through apodized diffraction. Patients are practically spectacle independent in that they can see at far, intermediate and near distances without glasses. For the finest print or prolonged periods of reading, some patients may require the help of reading glasses. A small percentage of patients, have noticed glare and halo symptoms. Your surgeon will discuss with you whether the multifocal implant is right for you.
The Crystalens relies on accommodation to focus at far, intermediate and near distances. The muscles inside the eye contract and relax to move the Crystalens, mimicking the movement of the natural lens. The glare symptoms are not significant with this implant. Patients enjoy excellent distance and intermediate vision, but most patients will require reading glasses for fine print. The Trulign is a lens implant that corrects for astigmatism on the Crystalens platform.
It is important to remember that these lens implants are designed to reduce but not completely eliminate the need for glasses or contacts. A patient’s visual outcome will depend on many factors including pupil size and general ocular health.
