The goal of this study is to collect more information about the safety and rate of visual distortions associated with TECNIS Toric intraocular lenses (IOLs), Models ZCT450, ZCT525 and ZCT600, which have already been approved by the US Food and Drug Administration (FDA). <br><br>To be eligible for this study, patients must have high corneal astigmatism in both eyes and must already be planning to have cataract surgery.
Be at least 22 years old
Have cataracts in both eyes
Have a certain degree of astigmatism in both eyes
Be willing and able to comply with examination procedures
Understand, read and write English to complete informed consent and questionnaires
Be available for study follow-up visits
Be currently in any other clinical study or have been in a clinical study during the last 30 days
Have a certain disease/illness such as poorly-controlled diabetes
Have certain eye conditions such as uncontrolled glaucoma
Be taking medication that may affect your vision
Be pregnant, planning a pregnancy, or breastfeeding
One eye must have a higher power toric IOL model ZCT450-ZCT600 implanted. The other (fellow) eye must have a standard IOL model ZCT300-ZCT600 implanted.
The rate of visual distortion with the higher power toric IOL will be compared to the standard IOL.
Costs of the surgery and IOLs will be billed to the patient’s insurance or to the patient. Patients will be compensated for time and travel.
