Filter by:The goal of this clinical trial is to learn about the visual performance of a new multifocal intra-ocular lens in patients presenting for cataract or refractive lens exchange surgery. The main question it aims to answer is: What is the visual performance and patient satisfaction twelve months post-operatively? Participants will receive bilateral implantation of the investigational device, undergo post-operative assessments, and provide feedback on their overall visual satisfaction.
This study is a multicentric, prospective, randomised, controlled, post-market clinical follow up (PMCF) study to investigate safety, visual outcomes and contrast sensitivity after bilateral implantation of either LuxSmart IOLs (study group) or LuxGood IOLs (control group).
Although postoperative infectious endophthalmitis and toxic anterior segment syndrome (TASS) rarely happen, they can threaten sight and are considered complications of intraocular and cataract surgery1. Reusing surgical supplies during cataract surgery, especially in developing countries, will have a treble impact in lowering the financial costs of surgery, the emissions of greenhouse gas, and environmental waste. Nearly half the waste of cataract surgery is recyclable, as reported by a prospective Malaysian study 8. Despite the increasing evidence of reusing the operative supplies, numerous healthcare professionals may be reluctant to consider it due to worries about cross-contamination among patients2. According to the Aravind Eye Care System (AECS) in Tamil Nadu, India, endophthalmitis rated 0.02% in over a million consecutive cataract cases despite the observation that cannulas, irrigation/ aspiration tubing, gowns, surgical gloves, irrigating bottles, as well as topical and intraocular drugs are normally recycled to cut cost and waste3,4. On the other hand, health care plays a key role in climate change, as well as financial and environmental waste2. Cataracts are the leading cause of blindness and visual impairment worldwide, making cataract surgery one of the most performed surgical procedures5. The carbon footprint of cataract surgery, especially phacoemulsification, is a significant research field6-8. In the United Kingdom, cataract surgery releases 180 kg of CO2- equivalents per eye, causing over half of the emissions due to obtaining large disposable medical equipment9. In ACES, phacoemulsification generated 5.9 kg of carbon emissions4. In comparison to the United Kingdom and the United States of America, the cataract surgery's low rates of infection in AECS were accomplished with 1/10 supply costs and 1/20 global warming emissions6. Being the most performed operation, cataract surgery and ophthalmology, in general, can meaningfully influence lowering environmental and economic waste in their surgical services1. The aim of this work is to show if reusing the operative supplies to reduce financial costs, especially in developing countries, and to lower global warming and climate change will affect the rate of postoperative endophthalmitis after cataract surgery
The goal of this observational study is to evaluate the rotational stability and clinical performance of the ASQELIO Toric lens in candidates for cataract surgery with ASQUELIO Toric intraocular lens (IOL) implantation. Information will be obtained from patients operated by routine clinical practice with toric monofocal ASQELIO IOL in at least one eye. After confirmation of inclusion, the preoperative examination will be performed, and after surgery an evaluation will be performed the following day, one week, one month and three months after surgery.
Cataract surgery presents an extremely high success rate in improving vision and quality of life and it is currently the most commonly performed ophthalmic surgery, especially considering its growing utility in the aging population (e.g., more than 20 million worldwide underwent the procedure in 2015); it is possible to affirm that benefits clearly outweigh risks. However, although cataract surgery is highly effective and relatively safe, owing to the enormous numbers, even uncommon surgical complications could potentially harm the patients. For this reason, it is essential to continue to consider the possible risks and undesirable side-effects associated to cataract surgery, such as post-cataract endophthalmitis (POE), postcataract opacification (PCO), PCME, dysphotopsias, retinal detachment, and IOL dislocation.
This study is a prospective, multi-site, multi-surgeon, observational study of refractive accuracy with the Argos using BTAL after successful cataract surgery. Subjects will be assessed pre-operatively, operatively and at 5-8 weeks postoperatively. Clinical evaluations will include measurement of visual acuity, manifest refraction, and preoperative biometry.
The goal of this clinical trial is to compare the visual performance between Intensity SL IOL and Panoptix IOL in men and women diagnosed with cataract who require cataract surgery procedure that meet the inclusion criteria and provide written informed consent will be enrolled in the study. The main questions it aims to answer are: 1. To show non-inferiority in binocular distance corrected visual acuity for far, intermediate and near distances after Trifocal IOL implantation. 2. To show non-inferiority in the Defocus Curve measurement 3. To show non-inferiority in Contrast Sensitivity measurement 4. To show non-inferiority in patient satisfaction Participants will attend a total of 10 study visits: 1 preoperative visit, 2 operations and 7 postoperative visits.
The Hanita CleaRing device is an intraocular implant designed for inhibition of PCO leading to reduction in the Nd:YAG treatment rate. The device is implanted into the capsular bag after the extraction of the crystalline lens and prior to implantation of the IOL. The device is manufactured by Hanita Lenses from a hydrophilic acrylic co-polymer which is being used for the production of Intra-ocular lenses.
This is a prospective comparative study that will be conducted at one clinical site in the United States, in which subjects who sign an informed consent form and fulfil all inclusion and exclusion criteria, will have OCT scans obtained using the test and the predicate devices. There will be two main types of analyses performed as part of this study, including 1) a precision analysis, and 2) an agreement analysis. The precision analyses will be conducted utilizing all complete complements of acceptable scans from the test devices and predicate device for each of the 3 configurations. A complete complement of acceptable scans can be defined as subjects having 3 acceptable replicate scans on each of the 3 devices, at each of the 3 configurations. This is also synonymous with 3 scans for each of the 3 configurations on all 3 devices. If subjects have more than 3 acceptable scans per configuration on a device, only the first 3 will be considered for analyses. The agreement analysis will be conducted utilizing the first set of acceptable scans from each instrument for all overlapping measurement types (for all measurement types two or more of the devices have in common) related to performance endpoints.
Subjects with cataract requiring extraction and who have open-angle glaucoma or ocular hypertension will undergo screening and washout from IOP-lowering medication, if applicable. Eligible subjects who meet all inclusion criteria and none of the exclusion criteria and who undergo successful cataract extraction with implantation of a posterior chamber intraocular lens (PC-IOL) will receive a travoprost intraocular implant and followed up for 12 months.
