5 Key Takeaways

1

Cataract surgery at physiologic IOP improves patient outcomes by reducing postoperative complications such as inflammation and corneal edema.
2

Advancements in phacoemulsification technology, like Active Fluidics, enhance chamber stability and minimize complications during cataract surgery.
3

Operating at lower IOP settings reduces zonular stress and the risk of capsule tears, improving safety during cataract procedures.
4

Despite benefits, lower IOP may limit surgical working space, necessitating higher IOP in certain challenging cases.
5

Gradual adjustment to physiologic IOP is recommended for surgeons to refine techniques while ensuring patient safety during cataract surgery.
