Purpose
To evaluate the safety, visual and refractive outcomes of high frequency deep sclerotomy (HDFS) combined with cataract surgery.
Setting
Sant’Anna University Hospital, Ferrara, Italy and Bufalini Hospital, Cesena, Italy.
Methods
In this multicenter retrospective study, 31 eyes of 31 patients with open-angle glaucoma who underwent HFDS combined with cataract surgery were included. Following standard phacoemulsification and IOL implantation, HFDS was performed with a custom-made high-frequency dissection 19G probe (abee tip 0.3×1mm, Oertli Switzerland), creating 6 pockets in the nasal sclera. Main outcome measures were analyzed 3 months after surgery and included visual acuity, prediction error (PE, calculated as the postoperative manifest spherical equivalent (SE) refraction minus the SE predicted refraction), intraocular pressure, the number of antiglaucoma active ingredients used, and complications. The SE predicted refractions were calculated using SRK/T formula.
Results
Three months after surgery, the average visual acuity increased from logMAR 0.38±0.23 to logMAR 0.11±0.16. Mean PE was +0.18±0.09 D. Intraocular pressure decreased from 16.6±3.2 mmHg to 13.6±2.0 mmHg. The number of active ingredients used decreased from 2.1±1.0 to 0.7±1.3. Hyphema was the most frequent complication (6.5%) but required anterior chamber washout only in 1 case.
Conclusions
HDFS combined with cataract surgery is safe and effective in reducing IOP. The procedure is associated with a modest hyperopic refractive shift.
