Brief summary
This study aims to compare the time required for surgical planning using these two methods and to explore whether differences in surgical accuracy can be identified in a small study of 40 patients.
Detailed description
This study aims to compare the time commitment for surgical planning using these two methods and to explore whether differences in surgical accuracy can be identified in a small study of 40 patients.
Interventions
DEVICEStandard of Care4
The current standard of care for surgical planning for the participating investigator surgeon is to use Zeiss Veracity Surgical, so this same method will be used for the surgery actually performed on participating patients.

Inclusion criteria
* Patients at least 18 years of age with upcoming cataract surgery. At least 25% of enrolled eyes must be post-refractive, and 25% must require astigmatic planning (arcuate incision or toric IOL) * Patients with otherwise healthy eyes, not exhibiting any significant ocular morbidity that would be expected to influence refractive outcome or interfere with postoperative refraction accuracy.
Exclusion criteria
* Patients with visually significant comorbidities (corneal, retina, optic nerve disease, not including prior refractive surgery) that could significantly affect their ability to have accurate preoperative biometry or postoperative refraction. * Patients with surgical complications either during or after surgery (capsule tears, iris trauma, decentered IOL, cystoid macular edema, etc.) that would interfere with postoperative refraction. * Patients with \> grade 2 or greater posterior capsule opacity

Other
| Measure | Time frame |
|---|---|
