Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To determine clinically significant difference in results obtained from cataract surgery using IA. One eye will receive aphakic measurements only and the fellow eye will receive aphakic and then pseudophakic measurements when implanting a toric IOL.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To determine if there is a clinically significant difference in the results obtained for the toric IOL implantation when using IA to measure the aphakic eye only and when using IA to measure the aphakic eye and then the pseudophakic eye, with toric IOL implantation.

Outcome Assessors

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Aphakic Measure only

Eye measured in aphakic state only

Group Type NO_INTERVENTION

No interventions assigned to this group

Pseudophakic measure

Eye measured in aphakic state then again in pseudophakic state with toric IOL using the ORA System. Pseudophakic measurement obtained will provide data about placement of toric iol and the surgeon will use that data to rotate the iol if necessary.

Group Type ACTIVE_COMPARATOR

Pseudophakic Measurement

Intervention Type DIAGNOSTIC_TEST

standard aphakic measurements will be taken and then pseudophakic measurements will be taken after toric iol implantation. The data produced will aid the surgeon in proper placement of toric iol orientation

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* willing and able to understand and sign an informed consent
* willing and able to attend all study visits
* presenting for uncomplicated bilateral cataract surgery and have an interest in a toric iol
* have good ocular health, with no pathology that compromises visual acuity (outside of residual refractive error)
* have visually significant cataracts
* have regular corneal astigmatism of 1.0D to 5.0D in both eyes with a difference between eyes of 1.0D or less
* have potential post operative acuity of 20/25 or better

Exclusion Criteria

* corneal pathology
* amblyopia
* prior corneal refractive surgery or other refractive surgery
* previous anterior or posterior chamber surgery that the investigator feels may compromise visual outcomes
* Diabetic retinopathy if the investigator feels this will compromise visual outcomes
* macular degeneration
* history of retinal detachment
* irregular astigmatism or keratoconus
* strabismus
* if in the surgeon's opinion the subject is not an appropriate candidate for iol implantation
* subjects who have an acute or chronic disease or illness that would confound the results of this investigation
