A study recently published in the Journal of Glaucoma highlights the potential benefits of blue-light filtering IOLs in reducing cases of glaucoma post-cataract surgery.
The study examined real-life data from cataract surgery patients who received either blue-light filtering or non-blue-light filtering IOLs and looked at the development and progression of glaucoma in each group.
Researchers evaluated data from over 11,000 patients who had uneventful cataract surgery between 2007 and 2018. 47% of those patients received the blue-light filtering IOLs and 53% did not receive them. Patients with pre-existing glaucoma were analyzed separately.
The analysis showed that the blue-light filtering group had fewer glaucoma diagnoses compared with the non-blue-light filtering group at 5 years, 7 years and 9 years after cataract surgery. For those who had a glaucoma diagnosis prior to surgery, there was no significant difference in any outcome.
