Purpose
The OMNI surgical system is a minimally invasive glaucoma surgery (MIGS) involves viscocanalostomy with or without trabeculotomy and is designed to reduce intraocular pressure (IOP) in glaucoma patients. This study evaluates its efficacy based on pre- and post-operative intraocular pressure reduction and antiglaucoma medication use.
Setting
Study was conducted in Southend University Hospital over a period of one year .
Data from 28 eyes of 28 patients were collected. 28 patients and 22 patients were available for outcome analysis at the end of 1 and 12 months respectively.
Viscocanalostomy and traberculotomy was performed as stand alone procedure in 5 eyes and in 23 was combined with phaco-emulsification. 360 degree visco-canalostomy with 90 trabeculotomy was done in 26 eyes ,in two eyes 360 and 180 degree viscodilatation was done.
Methods
A retrospective analysis of 28 patients with ocular hypertension and glaucoma undergoing surgery as a stand-alone procedure or comined with cataract surgery was conducted. Baseline IOP, number of medications, and postoperative outcomes were recorded over a 12 month follow-up period.
Complete success was defined as an IOP of < 21 mm Hg , 20% IOP reduction, and no use of IOP lowering medication
Qualified success was defined as complete success with the use of IOP lowering medication.
Failure was defined as an IOP>21 mmHg, <20% IOP reduction, surgical revision, further glaucoma filtration surgery, or loss of visual acuity to no perception of light.
One common complication was 1-2 mm hyphaema (N=5), which resolved within a month spontaneously.
Results
The rate of complete success was 60.71% (N=17) and qualified success 89.28% (N=25) and failure was 10.71% (N=3) 3 patients needed restarting of antiglaucoma treatment by 1 month,one of them developed steroid induced elevation of IOP and achieved more than 20% IOP reduction after a year without drops . At the end of 1 year, the rate of complete success was 45.45%% (N=10) and qualified success 81.81% (N=18), failure rate was 18.18% (N=4).
Preoperative mean IOP was 20.67 mmHg , post operative mean IOP was 17.30 mmHg at in 1 month (ie;16.30% reduction P < 0.05) and 16.4mmHg in 1 year (ie; 20.67% reduction P<0.05) . Antiglaucoma medication use decreased from an average of 1.71to 0.71. The outcomes were consistent across all glaucoma types.
Conclusions
The OMNI surgical procedure resulted in a statistically significant reduction in IOP within 2-4 week and one year post-operatively. OMNI surgery demonstrates significant efficacy in lowering IOP and reducing medication burden, offering a promising alternative for glaucoma management.
