Vision and Balance Changes After Bilateral Implantation of Toric IOLs

ClinConnect Summary

This clinical trial is investigating how a special type of artificial lens, called a toric intraocular lens (IOL), can improve vision and balance in patients with cataracts and astigmatism. Cataracts are a major cause of blindness, and many people undergo surgery to replace their cloudy eye lens with a standard lens. However, standard lenses do not correct astigmatism, which affects about 20% of the population. This trial aims to see if using toric IOLs, which are designed to correct astigmatism, can lead to better vision and potentially improve a person’s balance and mobility after surgery.

To be eligible for this trial, participants need to have significant astigmatism and be on the waiting list for cataract surgery. Some key criteria include being able to walk independently and not having certain eye conditions that could complicate the surgery. If you decide to participate, you can expect to receive the toric IOL during your cataract surgery, and the researchers will follow up with you to evaluate your vision and balance. This study could provide valuable information on how better vision can enhance daily life, so it’s an exciting opportunity for those affected by cataracts and astigmatism.
