Clinical Trial Summary

The primary objective of this clinical study is to assess the clinical performance of the PanOptix IOL in a Chinese population.

Description:

In this clinical study, subjects will be implanted with the PanOptix IOL in both eyes. The second eye surgery will occur 7-28 days after the first eye. A total of 11 scheduled visits are planned, including a screening visit, two operative visits, and 8 postoperative visits. The total expected duration of the subject's participation will be about 14 months. This study will be conducted in China.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Eyes With Best Corrected Distance Visual Acuity (BCDVA) Equal to or Better Than 0.3 LogMAR - Monocular	Visual acuity (VA) was assessed monocularly (eyes individually) with best refractive correction in place under photopic (well-lit) conditions at a distance of 5 meters using Chinese Standard Logarithmic VA charts. LogMAR typically ranges from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). Lower scores indicate better vision. No hypothesis testing was pre-specified for this endpoint.	Month 6 (180-210 days post second eye surgery, 187-238 days post first eye surgery)
Primary	Percentage of Eyes With Best Corrected Distance Visual Acuity (BCDVA) Equal to or Better Than 0.3 LogMAR - Binocular	VA was assessed binocularly (eyes together) with best refractive correction in place under photopic conditions at a distance of 5 meters using Chinese Standard Logarithmic VA charts. LogMAR typically ranges from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). Lower scores indicate better vision. No hypothesis testing was pre-specified for this endpoint.	Month 6 (180-210 days post second eye surgery, 187-238 days post first eye surgery)
Primary	Mean Best Corrected Distance Visual Acuity (BCDVA) - Monocular	Visual acuity (VA) was assessed monocularly (eyes individually) with best refractive correction in place under photopic (well-lit) conditions at a distance of 5 meters using Chinese Standard Logarithmic VA charts. LogMAR typically ranges from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). Lower scores indicate better vision. No hypothesis testing was pre-specified for this endpoint.

Primary	Mean Distance Corrected Intermediate Visual Acuity (DCIVA) - Monocular	VA was assessed monocularly (eyes individually) with distance correction in place (plus or minus power) under photopic conditions at a distance of 60 centimeters using Chinese Standard Logarithmic VA charts. LogMAR typically ranges from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). Lower scores indicate better vision. No hypothesis testing was pre-specified for this endpoint.
