Autofocusing Lens:
Multifocal, Accommodative, and Extended Range of Vision Lenses
SYMFONY, TECNIS, ReSTOR, CRYSTALENS, and TRULIGN
With Autofocusing Lenses you can expect to be less dependent on glasses for distance, intermediate and near vision. After having the autofocusing lens, most patients see very well for distance and intermediate without glasses. Some patients still need to use readers on occasion after surgery. This lens is designed for someone who wants the most advanced technology available for lessening dependence on glasses after surgery. If you select this option the surgeon will correct any astigmatism. You have an option to have any astigmatism corrected with a laser prior to having the cataract removed.

Further Options
Patients with nearsightedness and farsightedness often also have astigmatism. Astigmatism is caused by an irregularly shaped cornea; instead of being round like a basketball, the cornea is shaped like a football. This can make your vision blurry even after cataract surgery. The good news is that is can be corrected.
Depending on the severity of the astigmatism, the doctor may recommend one of the following two procedures:

Depending on the severity of the astigmatism, the doctor may recommend one of the following two procedures:
- Limbal Relaxing Incision (LRI) In addition to the Toric IOL, astigmatism can also be reduced by a procedure called a Limbal Relaxing Incision (LRI). The LRI can accompany any IOL. This procedure can be performed at the same time as the cataract operation, or as a separate procedure at a later date. A Limbal Relaxing Incision (LRI) is a small incision that the ophthalmologist makes into your cornea to make its shape rounder. Alternatively, the surgeon may elect to perform PRK to further reduce the astigmatism if the LRI is unsuccessful. Healing time is usually about a week.
- PRK If needed, PRK is another treatment for patients looking to reduce or eliminate astigmatism after cataract removal. This treatment option can be accompanied with the Monofocal IOL or the Multifocal IOL. Once the patient has healed completely from the cataract procedure, and the doctor has deemed them a good candidate, a patient may proceed with PRK Laser Treatment. Before the actual laser treatment takes place to reshape the cornea for the astigmatism correction, a tiny amount of tissue (the top surface lining called the epithelium) is removed. The epithelium grows back over the course of about a week. Because of this, healing time can vary from patient to patient.
