Clinical Study to Evaluate the RxSight Light Adjustable Lens With the Light Delivery Device in Subjects With Preoperative Corneal Astigmatism

Not Applicable

Completed

Brief Summary: For patients undergoing cataract surgery, the purpose of this study is to evaluate a patient's far vision without glasses and quality of vision after implantation and UV treatment of the RxSight Light Adjustable Lens (RxLAL).Following completion of all light treatments, the patient's far vision without glasses and quality of vision will be assessed 6 months postoperatively.

Inclusion Criteria

Must sign a written Informed Consent form and be willing to undergo cataract surgery for the bilateral implantation of the RxLAL.
Greater than the age of 40 on the day the cataract surgery is performed.
Preoperative keratometric cylinder of >=0.50 D and <=4.00 D in both eyes.
Cataract causing reduction in best corrected distance visual acuity (BCDVA) to a level of 20/32 or worse with or without glare source in both eyes.
Willing and able to comply with the requirements for study specific procedures and visits.

Exclusion Criteria

Zonular laxity or dehiscence.
Age-related macular degeneration involving the presence of geographic atrophy or soft drusen.
Retinal degenerative disorder or macular disorder (other than mild macular degeneration) that is expected to cause future vision loss.
History of uveitis
Keratoconus or suspected of having keratoconus.
Previous corneal or intraocular surgery, except eyes with previous pterygium excision are permitted as long as the pterygium did not extend more than 2mm onto the cornea from the limbus.
Serious co-morbid conditions that in the judgement of the investigator makes inclusion in the study not in the best interest of the subject.
Subjects taking systemic medications that may increase sensitivity to UV light.
