UNASSIGNED: This was a prospective, non-randomized, interventional comparison study done at the Veteran Affairs Hospital in Long Beach, California. All patients underwent cataract surgery with intraocular lens implantation combined with ab-interno canaloplasty and trabeculotomy with the OMNI Surgical System (SightSciences, Menlo Park, CA, USA), either superiorly or inferiorly. Pre- and post-operative intraocular pressure using Goldmann applanation tonometry and best corrected visual acuity were obtained and compared using paired t-tests. Patients were excluded if they had any prior intraocular surgery or prior laser trabeculoplasty procedures.
UNASSIGNED: 38 eyes from 29 patients were analyzed. 19 eyes were included in the superior group and 19 eyes in the inferior group. Mean pre-operative IOP in the superior group was 17.6 ± 5.2 mmHg and in the inferior group was 17.6 ± 4.6 mmHg (p > 0.99). At 12 months, mean postoperative IOP for the superior group decreased 24% to 13.3 ± 2.8 mmHg while the inferior group decreased 26% to 13.1 ± 2.2 mmHg (p = 0.92). Mean preoperative medications in the superior group were 2.2 ± 1.3 and in the inferior group was 2.4 ± 1.3 (p = 0.88). At 12 months, this decreased to 1.3 ± 1.5 post-operatively in the superior group and 2.2 ± 1.6 post-operatively in the inferior group (p = 0.64).
UNASSIGNED: There was no statistical difference in efficacy between superior versus inferior canaloplasty/trabeculotomy with OMNI. Therefore, surgeons can perform the procedure in the direction that is most comfortable for them without affecting outcomes.
■这是一个前景,非随机化,在长滩退伍军人事务医院进行的介入比较研究,加州所有患者均接受了白内障手术,人工晶状体植入术联合OMNI手术系统的ab-interno囊成形术和小梁切开术(SightSciences,MenloPark,CA,美国),无论是上级还是下级。使用Goldmann压平眼压法获得并使用配对t检验比较了手术前后的眼压和最佳矫正视力。如果患者先前有任何眼内手术或先前的激光小梁成形术程序,则将其排除在外。
■对29例患者的38只眼进行分析。上组19只眼,下组19只眼。上组术前平均眼压为17.6±5.2mmHg,下组为17.6±4.6mmHg(p>0.99)。12个月时,上组术后平均眼压下降24%,为13.3±2.8mmHg,下组下降26%,为13.1±2.2mmHg(p=0.92).上组平均术前用药为2.2±1.3,下组平均为2.4±1.3(p=0.88)。12个月时,上组术后下降到1.3±1.5,下组术后下降到2.2±1.6(p=0.64)。
■使用OMNI的上、下管成形术/小梁切开术的疗效无统计学差异。因此,外科医生可以在最舒适的方向进行手术,而不会影响结果。
