Evaluating the 1-year success and safety of ab interno canaloplasty in combination with cataract surgery in glaucoma patients

International Ophthalmology, vol. 44, pp. 406

Abstract

PURPOSE: To evaluate the treatment success and safety of ab interno canaloplasty (AbiC) combined with cataract surgery in glaucoma patients. METHODS: The prospective case study included 43 eyes that received an AbiC combined with cataract surgery (age 73.3 ± 8.2 years). The 360° microcatheterization and viscodilatation of the Schlemm's canal was conducted using VISCO 360 (Sight Sciences, CA, USA). The observation period was 12 months with visits at 2 and 6 as well as 12 months, 7 eyes were lost to follow up. RESULTS: The preoperative IOP was 19.8 ± 4.9 mmHg and was reduced to 14.5 ± 2.8 mmHg 12 months after AbiC (p < 0.0001). The relative IOP reduction was 23.6 ± 23.1% after 12 months. Topical glaucoma medication was also reduced from 2.4 ± 1.1 drugs to 1.1 ± 1.4 (p < 0.001) after 12 months. The complete surgical success rate (defined as IOP < 18 mmHg without topical therapy) was 31.6% whereas the qualified surgical success was 89.5% (IOP < 18 mmHg, with local therapy) There were no relevant intra- or postoperative complications. CONCLUSION: AbiC in combination with cataract surgery is a safe and effective procedure to achieve a significant reduction of IOP and local glaucoma medication 12 months after surgery.
