Brief summary
Intraocular lens technology has significantly developed over time to include multifocal and trifocal options. The motivated patient can now readily achieve optical independence for most circumstances. Previously, Alcon have provided the Panoptix Presbyopia Correcting IOL in spherical form only. Residual astigmatism has been shown to decrease unaided visual acuity. As approximately 40% of patients will have corneal astigmatism of 0.75D or greater, this represents a significant cohort of patients that may not adequately benefit from the Panoptix IOL in its current format. (Teresa JCRS 2009) The introduction of a toric option presents a positive opportunity for these patients to optimize their unaided vision at all distances. The objective of this study is to describe the visual outcomes and safety at minimum 6 months (180 days) post bilateral implantation of the Panoptix Toric IOL. Subject information will be drawn from a single study visit however preoperative and prior surgical information will be collated also.
Interventions
This study is a prospective consecutive audit of effectiveness following cataract surgery or refractive lens exchange surgery in subjects with pre-existing astigmatism requiring trifocal toric IOL consideration. Patients who have previously undergone routine cataract and intraocular lens replacement with a Panoptix Trifocal Toric IOL will be identified. Patients at 6 months post procedure will be contacted about returning for a review visit (study visit).

This study is a prospective consecutive audit of effectiveness following cataract surgery or refractive lens exchange surgery in subjects with pre-existing astigmatism requiring trifocal toric IOL consideration. Patients who have previously undergone routine cataract and intraocular lens replacement with a Panoptix Trifocal Toric IOL will be identified. Patients at 6 months post procedure will be contacted about returning for a review visit (study visit). Participants will undertake a single visit to confirm the visual acuity (distance, intermediate and near vision), refraction (prescription), defocus curve (best corrected vision at all distances), intraocular lens alignment and patient-reported outcome measurements (to measure vision-related quality of life). These tests will be undertaken by an experienced clinician with 20+ years in conducting ophthalmic examination and clinical trial assessments. The study requires attendance for a single study visit which is performed at least 6 months from the original uncomplicated procedure.

Inclusion criteria
Subjects are eligible for the study if they meet the following criteria: Note: Ocular criteria must be met in both eyes. - are more than 40 years of age, of either gender and any race; - have completed uncomplicated cataract surgery or refractive lens exchange surgery with the Alcon Panoptix Toric IOL at least 6 months prior (but no greater than 12 months) - regular corneal astigmatism requiring toric IOL correction
Exclusion criteria
If any of the following exclusion criteria are applicable to the subject or either eye, the subject should not be enrolled in the study. - Amblyopia - Previous anterior or posterior chamber surgery (e.g., vitrectomy, laser iridotomy) - Diabetic retinopathy - Macular degeneration - History of retinal detachment - Subjects who have an acute or chronic disease or illness that would confound the results of this investigation (e.g., immunocompromised, connective tissue disease, clinically significant atopic disease, diabetes, and any other such disease or illness), that are known to affect post-operative visual acuity.
