Toric IOLs are premium intraocular lenses that correct astigmatism as well as nearsightedness or farsightedness.Like toric soft contact lenses, toric IOLs can correct astigmatism because they have different powers in different meridians of the lens.During your preoperative exam and consultation, your cataract surgeon can help you choose the best IOL for your needs, as well as additional cataract surgery costs involved if you choose one of the following premium lens implants.Traditional intraocular lenses have a spherical optical design, meaning the front surface is uniformly curved from the center of the lens to its periphery.They also have alignment markings on the peripheral part of the lens that enable the surgeon to adjust the orientation of the IOL inside the eye for optimal astigmatism correction.Just prior to cataract surgery, the surgeon places temporary markings on the patient’s cornea that identify the location of the most curved meridian of the front of the eye.In some cases — even when a toric IOL is used — limbal relaxing incisions may be needed after cataract surgery to fully correct astigmatism.
The best intraocular lens for you depends on many factors, including your lifestyle and your specific visual needs.
Like multifocal contact lenses, these premium IOLs contain added magnification in different parts of the lens to expand your range of vision so you can see objects clearly at all distances without glasses or contact lenses.
Some studies have shown multifocal IOLs tend to provide better near vision than accommodating IOLs, but they also are more likely to cause glare or mildly blurred distance vision as a tradeoff.
Intraocular lenses (IOLs) are medical devices that are implanted inside the eye to replace the eye’s natural lens when it is removed during cataract surgery.
IOLs also are used for a type of vision correction surgery called refractive lens exchange.
