Study shows positive results for combined glaucoma and cataract surgery with iAccess device
The addition of goniotomy using the iAccess device may provide an additional intraocular pressure (IOP)-lowering effect and reduction of medication burden when combined with cataract surgery with concomitant iStent placement, according to a study presented at the ASCRS Annual Meeting 2023.
The iAccess device is a micro-invasive glaucoma surgery instrument that allows surgeons to adjust their goniotomy procedures to meet the individual needs of each patient through incision and excision of the trabecular meshwork and inner wall of the Schlemm’s canal.
The retrospective study included patients with preoperative IOP of at least 15mmHg who were on ≥1 IOP-lowering medication. Outcomes were measured as changes in IOP and medication burden.
At 3 months, the group undergoing cataract surgery with concomitant iStent inject W and goniotomy using the iAccess device had a lower post-op mean IOP than the group undergoing cataract surgery with only iStent inject W. In addition, the number of glaucoma medications was lower in the group undergoing goniotomy with the iAccess device.
The authors noted that further data collection with a larger number of eyes is needed to confirm the long-term benefits of the combined procedure.
