BACKGROUND: Torsional mode phacoemulsification results in more effective fragmentation of the nucleus due to a different movement of the phacotip. In this clinical study, we investigated the influence of a modified tip design and active fluidics on the efficacy of phacoemulsification and safety for the corneal endothelium. MATERIAL AND METHODS: We conducted a prospective randomized 2 : 1 study in which 40 patients were operated on with the mini-flared Kelman Tip using the Infiniti ® System (group 1), and 20 patients were operated on with the Intrepid ® Balanced Tip and the Centurion ® System...

Background: The aim of the study was to evaluate the long-term safety and efficacy of the Trabectome for Chinese glaucoma patients. Methods: This was a multicenter, retrospective, observational study. Glaucoma patients, except those with neovascular glaucoma, with/without a visually significant cataract were enrolled. The patients received Trabectome or a combined surgery with phacoemulsification and intraocular lens implantation. The primary outcome evaluation was a reduction in intraocular pressure (IOP), and the secondary outcomes were a reduction in glaucoma medication, the 2-year success percentages, and complications...

Purpose: To evaluate the accuracy of IOL power calculation using adjusted corneal power according to the posterior/anterior corneal curvature radii ratio. Methods: Nine hundred twenty-eight eyes from 928 reference subjects and 158 eyes from 158 cataract patients who underwent phacoemulsification surgery were enrolled. Adjusted corneal power of cataract patients was calculated using the fictitious refractive index that was obtained from the geometric mean posterior/anterior corneal curvature radii ratio of reference subjects and adjusted anterior and predicted posterior corneal curvature radii from conventional keratometry (K) using the posterior/anterior corneal curvature radii ratio...

Purpose. Analysis of functional outcome and complications reported in patients diagnosed with phacomorphic glaucoma, in which phacoemulsification or extracapsular extraction of the lens was performed. Methods. The retrospective study included 38 eyes diagnosed with phacomorphic glaucoma. In 25 cases, group 1, the lens was removed by phacoemulsification and in 13 cases, group 2, by extracapsular extraction. Intraocular pressure, visual acuity, and anterior chamber depth were evaluated preoperative and postoperative...

PURPOSE: Cataract surgery has been reported to adversely affect the IOP control in eyes with the glaucoma drainage implant (GDI). One reason might be the flow of lens debris/viscoelastic material through the GDI tube into the bleb. This pilot study was conducted to determine the clinical results of a novel technique for temporary occlusion of the GDI tube with an iris retractor hook during phacoemulsification. METHODS: Retrospective analysis of 15 patients (control group) who underwent phacoemulsification between January 2005 and December 2010 and 17 patients (treatment group) who underwent phacoemulsification with the hooked tube technique between January 2011 and April 2016 with a minimum 1-year follow-up...

AIMS: To test a hypothesis that cataract operating room (OR) productivity can be improved with a femtosecond laser (FL) using a hub-and-spoke model and whether any increase in productivity can offset additional costs relating to the FL. METHODS: 400 eyes of 400 patients were enrolled in a randomised-controlled trial comparing FL-assisted cataract surgery (FLACS) with conventional phacoemulsification surgery (CPS). 299 of 400 operations were performed on designated high-volume theatre lists (FLACS=134, CPS=165), where a hub-and-spoke FLACS model (1×FL, 2×ORs=2:1) was compared with independent CPS theatre lists...

INTRODUCTION: An increasing number of patients are taking novel oral anticoagulant (NOAC) medication, making perioperative management in phacoemulsification surgery an important issue. This study reports the haemorrhagic complications of NOAC in phacoemulsification surgery. DESIGN: Retrospective case study over a 4-year period. METHODS: Consecutive cases receiving NOAC during the time of phacoemulsification were reviewed. Patients were either advised to continue medications (continued group) or withhold medications before surgery (withheld group)...

PURPOSE: To determine if phacoemulsification with intraocular lens implantation has a greater impact on the corneal endothelium of type 2 diabetic patients as compared to nondiabetics. MATERIALS AND METHODS: This study compared the endothelial status in 60 diabetics with good glycemic control and 60 nondiabetics before and after uneventful phacoemulsification. Central corneal endothelial cell density, percentage hexagonality and percentage coefficient of variation (%CV) were measured using a specular microscope...

PURPOSE: To compare the efficacy and safety of endoscopic cyclophotocoagulation (ECP) versus trabeculectomy with mitomycin C (trab) in combination with cataract surgery. MATERIALS AND METHODS: We evaluated the 6-month results of patients undergoing phacoemulsification (phaco) with either ECP or trab. The primary outcome was mean intraocular pressure (IOP) at 6 months; secondary outcomes were change in glaucoma medications, visual acuity, intraocular inflammation, and postoperative complications...

OBJECTIVE: To test a sub-Tenon's anesthesia technique in dogs as an alternative to systemic neuromuscular blockade to aid in canine cataract surgery under general anesthesia. PROCEDURES: A prospective controlled clinical study was performed involving 12 dogs undergoing bilateral cataract surgery under general anesthesia. One eye was randomly assigned to have phacoemulsification and prosthetic lens implantation performed with sub-Tenon's anesthesia (STA), and the control eye had surgery performed with systemic neuromuscular blockade (NMB)...

BACKGROUND: With increasing availability of toric intraocular lenses (IOL) for cataract surgery, real-world refractive outcome data is needed to aid the counselling of patients regarding lens choice. We aim to assess the outcomes of toric intraocular lens use in the non-specialist environment of a typical United Kingdom NHS cataract service. METHODS: A retrospective cohort study conducted at the Oxford Eye Hospital, Oxford University Hospitals NHS Foundation Trust, UK...

PURPOSE: To report a case of spontaneous dislocation of a gelatin microstent six months after the initial uncomplicated surgery. PATIENTS AND METHODS: We describe a 73-year-old male with a history of advanced primary open angle glaucoma who had previously undergone an unsuccessful micropulse transcleral cyclophotocoagulation (CPC) of the left eye. He underwent an uncomplicated combined phacoemulsification with an ab interno gelatin microstent, but was noted to have a spontaneous dislocation of the microstent six months post-operatively...

Background: In most cases, hydration is performed by water injection into the stromal tissue with a needle. The technique is simple, however it is sometimes troublesome. Purpose: We describe a simple technique for hydrating the corneal stroma in cataract surgery using an irrigation port. Patients and methods: The technique began by pushing the irrigation port against the corneal stroma for a few seconds during phacoemulsification, which generated edema in the corneal incision that subsequently prevented leakage...
