This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
During cataract surgery, doctors remove your cloudy natural lens and implant an artificial one to restore your vision. This trial is testing several brands of these artificial lenses — including Rayner RayOne, Hoya Nanex, Hoya Vivinex, Alcon Clareon, and PODEYE — to see how well they stay in the correct position inside your eye after surgery. Some versions are specially designed to correct astigmatism (blurred vision caused by an irregularly shaped cornea).
The position of an artificial lens is crucial for clear vision after surgery. This trial exists to compare different lens brands and designs to find which ones are most stable and reliable over time, helping doctors choose the best option for future cataract patients.

You will undergo standard cataract surgery with implantation of one of the study lenses, positioned at a specific angle (0°, 45°, 90°, or 135°). After surgery, you'll return for follow-up eye exams at 1 hour, 1 week, 1 month, and 4 to 7 months to check your vision, lens position, and overall eye health. Each visit will include standard tests like vision measurements and a slit-lamp examination (a microscope used to look at your eye).
