Filter by:Topical anaesthesia of the eye for ophthalmologic procedures avoids pain and discomfort of local anaesthetic injection in the peribulbar or retrobulbar block so that patient comfortability is achieved. Sedation during topical anaesthesia of the eye is mostly required to achieve anxiolysis, amnesia and keeping the patient calm all through the procedure. In the present study, the investigators will investigate the effect of nalbuphine/dexmedetomidine versus nalbuphine/propofol on the sedation as a primary outcome, intra-operative, postoperative analgesia, vital signs, patient and surgeon satisfaction and side effects as secondary outcomes
Purpose: To assess the time-efficiency of a designated operation room (OR) workflow in the introduction of Femtosecond laser-assisted cataract surgery (FLACS, LenSx, Alcon®). The study was carried out in a public hospital with high volume of procedures. Setting: Ophthalmology department of a tertiary referral Spanish public hospital. Design: Prospective, controlled, surgical intervention study. Methods: A total of 167 eyes were enrolled, including 62 eyes undergoing conventional phacoemulsification surgery. In phase I, patients were assigned either to FLACS-I (n=63) or conventional phacoemulsification surgery (n=62). One surgeon operated the Femto-second laser, another finished the procedure, whereas another performed a conventional phacoemulsification. In the second phase (FLACS-II), all the surgeries were FLACS (n=42). A surgeon performed the FLACS procedure and two different surgeons completed the surgeries in separated ORs. Surgical and roll-over times of all the patients were recorded.
The objective of this study is to obtain an initial assessment of the safety and performance of an investigational AIOL in patients undergoing cataract extraction and IOL implantation.
Purpose: The aim of this retrospective study is to investigate the end tidal carbon dioxide pressure (ETCO2) values in order to determine the carbon dioxide accumulation under drape and to investigate it's hemodynamic effects based on anesthetic and surgical records in eye surgeries under local anesthesia. Methods: The data were collected from anesthetic records of the patients who were followed with noninvasive capnograph (Capnostream 20 p, Oridion®, Israel) by the anesthesiology department in the operating room at Duzce University Faculty of Medicine Hospital during the period of January 2016 to December 2016. Collected data from the 42 patients' records were systolic, diastolic and mean arterial pressures, operation duration, total local anesthetic and, heart rate, ST segment analysis, ETCO2 pressure, pulse oximeter values. The time periods of collected datas were determined as: after the anesthesia and before drape closure (baseline level), at 10th, 15th, 20th, 45th of the surgery and 5 minutes after drape removal.
The main objective is to describe the characteristics of dry eye syndrome before and after surgery at one month of cataract surgery, using a multimodal analysis of the ocular surface. The secondary objectives are to evaluate: - Predictive factors of dry eye syndrome during cataract surgery: - The characteristics of dry eye syndrome - Implications for the patient's quality of life
This study involved children with congenial cataract eyes, who underwent cataract surgeries at the Eye Hospital of Wenzhou Medical University (Hangzhou, China). All medical records were reviewed for primary diagnosis. All surgeries were performed by one experienced surgeon (Z.Y.E) and videos were collected for reviews in details. the clinical data after the surgery were also recorded for further analysis.
This study aims to compare the retinal perfusion between diabetic and non-diabetic patients with Optical Coherence Tomography（OCT） Angiography after cataract surgery, to thoroughly evaluate the retinal state of diabetics after surgery, and to find out the relationship between postoperative complications occurred in retina and diabetes.
The objective of this study is to evaluate, for the visual correction of aphakia, whether the RxSight Light Adjustable Lens (LAL) and Light Delivery Device (LDD) can be used to improve visual outcomes after performing adjustments of the LAL with the LDD. This is an exploratory study. No primary effectiveness endpoints will be identified.
Optical coherence tomography (OCT) for retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) is done before and after cataract extraction in patients with or without primary open angle glaucoma (POAG)
Clinical Outcomes of Prolensa (Bromfenac Ophthalmic Solution) 0.07% QD vs. Ilevro (nepafenac Ophthalmic Suspension) 0.3% QD with extra (pulse) dose on day of surgery for Treatment of Ocular Inflammation Associated with Cataract Surgery
