Background and Aims: Peribulbar anesthesia is associated with delayed orbital akinesia compared with retrobulbar anesthesia. To test the hypothesis that rocuronium added to a mixture of local anesthetics (LAs) could improve speed of onset of akinesia in peribulbar block (PB), we designed this study. This study examined the effects of adding rocuronium 5 mg to 2% lignocaine with adrenaline to note orbital and eyelid akinesia in patients undergoing cataract surgery. Material and Methods: In a prospective, randomized, double-blind study, 100 patients were equally randomized to receive a mixture of 0...

Kellam D Bayley, R A Read
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)...

PURPOSE: To compare the effect of two exposure durations of mitomycin C in combined angle and filtering surgery for primary congenital glaucoma. METHODS: This was a prospective study conducted in the Department of Ophthalmology at Alexandria Main University Hospital, Alexandria, Egypt, on 75 eyes with primary congenital glaucoma that underwent combined trabeculotomy-trabeculectomy with intraoperative mitomycin C application for 1 minute (MMC 1) or 2 minutes (MMC 2) and were followed up for 24 months...

Objective: To report the clinical results of pediatric penetrating keratoplasty (PKP) in patients under 3 years old with congenital corneal opacity. Methods: Retrospective study. Sixteen eyes of 12 patients who were treated with PKP in Aier Eye Hospital Group from June 2009 to December 2016 were enrolled in this study. All the patients were diagnosed as congenital corneal opacities: 8 cases (11 eyes) with Peter's anomaly I, 2 cases (3 eyes) with sclerocornea, and 2 cases (2 eyes) with corneal dermoid tumor combined with iris synechia...

Background: The cataract surgery anesthesia should be to make the procedure as safe and as satisfactory as possible for all concerned. The recent progress in anesthesia and surgery now allow cataract extraction to be done with minimal physiological changes to the patient. We aimed in the study to compare between two different doses of dexmedetomidine combined with lidocaine and bupivacaine during retrobulbar anesthesia for cataract extraction by phacoemulsification. Materials and Methods: This study was done on forty patients with cataract...

Background: The use of succinylcholine for rapid sequence induction in patients with open globe injuries may be detrimental to the eye. Aim: The aim of this study is to determine if the premedication with magnesium sulfate (MgSO4) could attenuate the increase in intraocular pressure (IOP) associated with succinylcholine injection and intubation. Setting: Operation theaters in a tertiary care University Hospital between December 2014 and July 215...

The present case report aims to describe and discuss the approach for the management of difficult endotracheal intubation in an adult with Down syndrome undergoing cataract surgery. A 26-year-old female with Down syndrome and a validated diagnosis of cataract requiring surgery was examined in order to assess the degree of difficulty of endotracheal intubation. Patients with Down syndrome have characteristic craniofacial abnormalities which require a thorough pre-operative assessment to anticipate and prepare for a difficult endotracheal intubation...

PURPOSE: To describe the use of a mobile femtosecond laser platform in assisting paediatric cataract surgery. METHODS: A mobile femtosecond laser was brought into the operating room and calibrated on the day of the surgery. After general anesthesia is induced, the femtosecond laser was docked onto the eyes with a liquid-filled interface, without any perioperative adaptations or additional surgical procedures. An anterior capsulotomy was created with the femtosecond laser, followed by conventional cataract extraction and intraocular lens implantation...

RATIONALE: Iridoschisis is a rare eye disease. In this case report, we described the examination and diagnosis of a case of iridoschisis accompanied by secondary glaucoma. We also observed the effects of treating the patient with a combination of goniosynechialysis and cataract removal. PATIENT CONCERN: A 67-year-old female patient presented with decreased vision in both eyes. An eye examination indicated that visual acuities (VAs) were 20/100 and light perception in the right and left eyes, respectively...

More than 26 million Americans suffer with cataracts, and with 3.6 million cataract extractions performed annually in the United States, it is the most common surgical procedure. The integrity of the delicate structures of the eye that mediate vision is dependent on the intraocular pressure (IOP). Yet, IOP acts to compress the vessels within the globe-akin to a Starling resistor-and is a key component that determines the ocular perfusion pressure, defined as the difference between arterial pressure and IOP...

Massachusetts health care facilities reported a series of cataract surgery-related adverse events (AEs) to the state in recent years, including 5 globe perforations during eye blocks performed by 1 anesthesiologist in a single day. The Betsy Lehman Center for Patient Safety, a nonregulatory Massachusetts state agency, responded by convening an expert panel of frontline providers, patient safety experts, and patients to recommend strategies for mitigating patient harm during cataract surgery. The purpose of this article is to identify contributing factors to the cataract surgery AEs reported in Massachusetts and present the panel's recommended strategies to prevent them...

BACKGROUND: The amount of sedation and muscle relaxation of the jaw may have an impact on complications caused by laryngeal mask airway (LMA). The aim of this study is to evaluate the effect of low-dose Atracurium on conditions of insertion, complications, and hemodynamic responses to LMA insertion following induction of anesthesia with propofol, in patients undergoing cataract surgery. PATIENTS AND METHODS: In this double-blind randomized clinical trial study, 60 patients were randomly divided into two groups...

PURPOSE: To evaluate postoperative outcomes of cataract surgery in children with persistent hyperplastic primary vitreous (PHPV) and factors affecting outcomes. METHODS: We analyzed 29 eyes of 28 children with PHPV presenting at a tertiary care center in northern India. All eyes underwent phacoaspiration followed by primary posterior capsulotomy with or without cauterization of persistent fetal vasculature under general anesthesia. Hydrophobic intraocular lens was implanted in selective cases...

PURPOSE: A major obstacle to the widespread implementation of nanosecond laser cataract removal has been its limited efficacy in cases when the cataract is harder than Lens Opacities Classification System III (LOCS III ) grade 3. The latest technological modifications seem to have overcome this obstacle. DESIGN: A case series. METHODS: This study presents a case series of 17 consecutive patients with a cataract classified as harder than LOCS III grade 3 who underwent nanolaser cataract surgery...

BACKGROUND: Despite recent innovations in cataract surgery, pupillary diameter is one of the most important affecting factors in outcome of this surgery. As cataract surgery is performed ideally when the pupil is sufficiently dilated, anesthesia may contribute significantly in success or failure of this operation. This study was performed to evaluate the effect of nitrous oxide on pupillary diameter in cataract surgery under general anesthesia. METHODS: Forty patients with cataract, scheduled for operation under general anesthesia, were randomly allocated into two groups...

PURPOSE: To review the history of cataract surgery over the past 100 years, and to offer predictions about new developments that may occur during the next 50 years. DESIGN: Interpretive essay. METHODS: Review of historical literature and author experiences pertaining to cataract surgery, with commentary and perspective. RESULTS: By this time, cataract surgery has advanced to the point that Kelman's introduction of phacoemulsification and use of intraocular lenses (IOLs), both very controversial when initially introduced, have become state of the art...
