Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 45 to 95 with uni- or bilateral age-related cataracts requiring surgery and specific astigmatism levels.

Probably not a fit

Patients with a history of ocular surgery, uncontrolled glaucoma, or other significant ocular diseases may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of various hydrophobic acrylic intraocular lenses (IOLs) in patients undergoing cataract surgery. Participants with age-related cataracts and astigmatism will receive one of three types of toric IOLs, and their postoperative outcomes will be assessed through visual acuity and lens rotation evaluations at multiple time points. The study aims to determine the optimal lens type for improving vision in patients with specific astigmatism levels. All procedures will be conducted following informed consent from the participants.

Why it matters

Potential benefit: If successful, this study could lead to improved visual outcomes for patients undergoing cataract surgery with astigmatism.

How similar studies have gone: Previous studies have shown positive outcomes with similar approaches using toric IOLs for astigmatism correction in cataract surgery.
