Device: Clareon Toric IOL
Procedure: Cataract surgery
Registration Number
NCT06285695
Lead Sponsor
Alcon Research
Brief Summary

The purpose of this post-market study is to describe the long-term safety and performance of Clareon Toric Intraocular Lenses (IOLs).

Detailed Description

Subjects will attend up to 12 scheduled visits (one preoperative visit, up to two surgical visits, and up to 9 postoperative visits) over the course of the study (3 years follow-up). The overall study duration is expected to be approximately 4 years. This study will be conducted in Canada.

Primary Outcome Measures
NameTimeMethod
Mean monocular best corrected distance visual acuity (BCDVA)Month 6, Year 1, Year 3 (post implantation)

Visual acuity will be assessed for each eye individually using letter charts and recorded in logarithm minimum angle of resolution (logMAR).

Secondary Outcome Measures
NameTimeMethod
Mean absolute IOL rotation from previous visitMonth 1 to Month 3, Month 3 to Month 6, Month 6 to Year 1, Year 1 to Year 3 (post implantation)

The difference in IOL axis of orientation from the previous visit will be assessed by a reading center and recorded in degrees.

Mean absolute IOL rotation from end of surgery supine baseline to each subsequent visitBaseline, Day 1, Week 1, Month 1, Month 3, Month 6, Year 1, Year 3 (post implantation)

The difference in IOL axis of orientation from baseline (end of surgery, patient laying flat) will be assessed by a reading center and recorded in degrees.

Mean monocular absolute residual refractive cylinderMonth 3, Month 6, Year 1, Year 3 (post implantation)

The amount of residual astigmatism will be assessed for each eye individually using letter charts and recorded in diopters.
