Early success and safety of three minimally invasive glaucoma surgery techniques combined with cataract surgery in glaucoma patients.

PURPOSE: To evaluate the efficacy and safety of three minimally invasive glaucoma surgery (MIGS) techniques, OMNI® Surgical System (OMNI), VISCO360® Surgical System (VISCO) and goniotomy using the Kahook Dual Blade (KDB) in combination with phacoemulsification in glaucoma patients.

METHODS

This prospective observational study over 6 months included 93 glaucoma patients who underwent one of the three MIGS combined with cataract surgery. Indications for surgery were insufficient intraocular pressure (IOP) control under topical medication or reducing the medication burden. Complete success was defined as reaching IOP < 21 mmHg without topical medication while qualified success was considered reaching IOP < 21 mmHg with topical medication.

RESULTS

The preoperative IOP was lowered significantly after 6 months for all 3 MIGS procedures and no significant differences in-between the 3 devices were recorded. Topical glaucoma medication was also reduced in all three groups, without a significant difference. Complete surgical success was the highest in KDB patients after 6 months at 74.2%, followed by 58.1% in VISCO and 48.4% in OMNI patients.

CONCLUSION

OMNI, VISCO or KDB in combination with phacoemulsification are safe and effective treatment options for glaucoma patients. The KDB and VISCO groups achieved higher success rates than OMNI, however, no significant differences in medication burden as well as IOP were recorded in-between the 3 devices.
