Phacoemulsification and Viscocanalostomy With or Without Silicone Implant in Primary Open-angle Glaucoma: A Randomized Clinical Trial

Our study found no significant difference in success rates or postoperative IOP control between combined phacoemulsification and viscocanalostomy with or without silicone implants. Although the case group demonstrated larger scleral lake dimensions on AS-OCT, this anatomical difference did not translate into superior IOP outcomes and was associated with a higher requirement for postoperative ocular hypotensive medications. The clinical significance of increased scleral lake size in the presence of an implant remains uncertain, and longer-term follow-up is warranted.
