3 Factors That Can Influence Your Intraocular Lens Choice For Cataract Surgery
Cataract surgery not only gives you the opportunity to have clearer vision by removing the affected lens, but you may have the opportunity to choose the type of lens replacement for even better vision. If you have the option to choose your intraocular lens (IOL), there are certain factors that may affect your decision.
Cost
The major influence on what lenses are available to you for cataract surgery will be the cost. Any insurance that will cover the costs associated with the surgery will, at minimum, cover the costs associated with a monofocal lens, which is considered a basic or standard lens. There are many other types of lenses on the market that can cover a wider range of vision concerns, but these may not be covered by your insurance plan. Depending on your insurance and your budget, you may want to pay out-of-pocket for a better lens. For some people, the upfront out-of-pocket costs may be a better option than the regular costs associated with corrective measures, such as the yearly expenses associated with corrective measures.
Nearsightedness/Farsightedness
The standard lens frequently used in cataract surgery can address nearsightedness. Unfortunately, standard lenses do not address the vision issues for objects that are closer to you or at other distances. Since these lenses do not provide accommodation for a range of visions, you will still need other corrective measures, such as glasses or contacts, especially if you are farsighted. As an alternative, you may want to choose a lens that can address a range of vision needs, such as a multifocal or accommodating lens. Multifocal lenses can allow you to see near and far objects, and in some instances, intermediate objects may also be easier to see with trifocal lenses.
Astigmatism
Having astigmatism is another vision concern you should consider when choosing your lens. Much like contact lenses, IOLs are available that can address astigmatism. Toric lenses may be the right option for people who have significant astigmatism that substantially affects their vision. Often, mild astigmatisms that go unnoticed with traditional corrective measures may not be worth the added cost of a toric lens. People with a combination of vision issues, such as astigmatism with the need for correction at near or far distances, may also have the option for lenses with both toric and multifocal features.
Since the new lens used during cataract surgery can correct some vision problems, it is worth investigating each type. Selecting a specialty IOL can help you achieve additional vision improvements after the procedure. For more information, contact a local eye doctor that offers cataract surgery services.
