Cataracts are a common eye disorder characterized by a cloudiness of the natural lens of the eye. The result is hazy or blurred vision. In addition to cataracts, you may also have other refractive problems such as myopia (nearsightedness), hyperopia (farsightedness) or astigmatism, which require prescription correction.
The correction of cataracts can only be done by surgically removing the natural lens and replacing it with an artificial intraocular lens. And, in order to potentially abandon your glasses and contact lenses after cataract surgery, you will need to choose a lens implant designed to address your unique refractive errors. There are a number of different intraocular lenses to choose from, including the AcrySof Toric Lens.
The standard intraocular lens used in cataract surgeries will correct the hazy vision caused by the cataract, but it won’t provide you with prescription vision correction. Without using modern premium lenses like the Toric lens, you will most likely need glasses or contact lenses after surgery.
The AcrySof Toric Lens (IOL) is specially designed to correct astigmatism and near or farsightedness in cataract patients.
Corneal astigmatism occurs when the cornea is not perfectly round. One side of the curve is steeper than the other, like a football. This causes light to focus at multiple points in the back of the eye, which creates blurred vision. Most eyes with refractive error have some level of astigmatism. The Toric lens is designed to correct for this vision defect by properly focusing the light scattered by the astigmatism.
The AcrySof Toric intraocular lens is particularly advantageous due to the AcrySof material. The patented AcrySof material is made from acrylic and, unlike other hard plastic intraocular lenses, it can be folded and inserted into the eye through a tiny incision. This means that sutures are typically not required to close the incision. Also, AcrySof IOLs are easier for surgeons to handle than silicone implantable lenses, making surgery safer. Studies have shown that the risk of post-operative complications using AcrySof IOLs is lower in comparison to silicone lens implants.
The AcrySof Toric lens has an additional benefit over standard implantable lenses. Besides vision correction, these intraocular lens implants also protect against UV blue light by approximating the natural yellowing of the crystalline lens with age. The yellow tint of the lens implant filters out blue light which can be damaging to the retina and can cause loss of vision. This feature does not change your color perception and may actually enhance it.
Corneal astigmatism in cataract patients is also commonly treated with astigmatic keratotomy (AK). In this procedure, strategic limbal relaxing incisions (LRIs) are made in the cornea to reshape it to be more spherical. After the eye heals, better visual acuity can be expected. The Toric intraocular lens can be used as an alternative to astigmatic keratotomy for cataracts patients.
Because the Toric IOL is implanted during the cataract surgery, it can potentially prevent the need for additional AK surgery in the future. However, those who have severe astigmatism may need to have AK surgery even after cataract surgery with AcrySof Toric lenses. As with all surgeries, there is the potential for some complications. Infection and the lens rotating out of position are the two main risks with Toric IOLs, and this can be discussed with the surgeon.
