Abstract Details

Purpose:

To compare the 6-month surgical outcomes of patients after combined phacoemulsification with intraocular lens implantation, trabecular meshwork bypass stenting, and canaloplasty versus combined phacoemulsification with intraocular lens implantation and bypass stenting alone.

Setting:

Pacific Eye Institute, Upland CA, United States.

Methods:

This study comprises a retrospective, non-randomized comparative case series of primary open-angle glaucoma surgeries in which 71 eyes of 65 patients underwent combined phacoemulsification with IOL implantation, trabecular bypass stenting, and canaloplasty and 93 eyes of 66 patients underwent phacoemulsification with IOL implantation and bypass stenting alone. All operations were performed by a single surgeon and all patients were followed postoperatively for a minimum of 6 months. Main outcome measures were: pre- and postoperative intraocular pressure (IOP), number of glaucoma medications used, and best corrected visual acuity (BCVA).

Results:

By 6 months postoperatively, mean IOP had declined by 24±7% in the phacoemulsification, trabecular bypass stenting, and canaloplasty group, compared to only 15±5% in the phacoemulsification and bypass stenting alone group (P=0.045). No statistically significant difference was found between the two groups in number of glaucoma medications used (pre- or postoperatively), or BCVA after surgery, and no intra- or postoperative complications (including persistent hyphema or hypotony) were experienced in either group.

Conclusions:

Phacoemulsification, trabecular meshwork bypass stenting, and canaloplasty achieved a statistically significant, additional IOP lowering effect compared to phacoemulsification and bypass stenting alone.
