ClinConnect Summary

This clinical trial is studying two different methods to correct astigmatism during cataract surgery: one method uses a special laser called femtosecond laser arcuate keratotomy, while the other uses a Toric intraocular lens. Astigmatism is a common vision problem that can affect how clearly you see, especially after cataract surgery. The goal of this study is to see which method works better for improving vision quality and patient satisfaction. Participants will have one eye treated with the laser and the other eye fitted with the Toric lens, and their vision will be monitored over time to compare the results.

To be eligible for this trial, you need to be a cataract patient with regular corneal astigmatism between 0.75 and 3.00 diopters, and you should be planning to have femtosecond laser-assisted cataract surgery. Unfortunately, if you have certain eye conditions, past eye surgeries, or severe health issues, you may not qualify. If you join the study, you can expect regular check-ups to assess your vision and how well each treatment is working, helping researchers understand which option could be better for patients in the future.
