Filter by:This study summarizes the experience of precision treatment and postoperative management of various types of cataract, and intend to further improve the quality of Clinical Cataract diagnosis and treatment.
Approximately 60 participants at Eye Hospital of Wenzhou Medical University during January,2017 to June 2021 will be enroll in our study. And dived them randomly into 2 groups:Progressive Cracking Technique (30 eyes) and Conventional Chop Technique (30 eyes) .
The ocular biometric parameters of the children with congenital cataract including preoperative pupil diameter, corneal diameter, axial length, anterior and posterior capsule size, iris adhesion. And then analysis whether the preoperative parameters were correlated with the implantation site of secondary implantation.
Cataract surgery is the most common surgical procedure performed on humans today. The postoperative regimen includes a combination of steroids, NSAIDs (non-steroidal anti-inflammatory drugs) and antibiotics. Those are used to decrease the possibility of infection, inflammation that may lead to corneal and macular edema and pain management. There are several FDA approved agents either for topical use as single drug delivery or combination solutions for topical use as well; furthermore, there are slow release vehicles that may be placed at the time of surgery or postoperatively (at the lower punctum). The latter provides a less intense and demanding drop schedule and may improve patient compliance.
Most patients treated for cataract surgery benefit from a short outpatient course with topical local anesthesia. Having to undergo surgery, especially on the eye, without being asleep, can be stressful. Sometimes waiting in a waiting room with other patients can increase this stress. Patient anxiety may increase blood pressure potentially leading to the prescription of nicardipine to allow surgery to be performed. The patient's anxiety also increases the surgeon's stress, which can alter the conditions for performing the intervention and increase the risk of intraoperative complications. Besides the administration of anxiolytics, nurses have few options for patients with anxiety. However, the treatment response time is not always appropriate and the patient's cooperation during the procedure can sometimes be impaired. The effect of music on preoperative anxiety has been evaluated in several studies and has shown a significant decrease in anxiety before surgery. MusicCare® is a "digital treatment" based on the principles of hypnoanalgesia which has been tested in the management of patients with various pathologies (depression, Alzheimer's disease, chronic pain, etc.) and has shown relative effectiveness. the absence of intervention on the pain and anxiety of patients. In the context of cataract surgery with topical local anesthesia, we would like to assess the contribution of offering the MusicCare® listening device on patients' anxiety about absence
To assess the rotation stability of toric intraocular lenses between sitting or routine settings (sitting, going around) after cataract operation.
The investigational device is an approved femtosecond laser (FSL) device with an integrated imaging system to perform certain steps of the cataract procedure. The FSL will perform anterior capsulotomy and lens fragmentation in individuals suffering from age-related cataract with need of cataract surgery. The laser will be reduced to image the Berger space. If not visible, the space will be enhanced with BSS and Volon A to visualize the BS. Cataract surgery will be performed in subjects who have signed an informed consent form. Macula thickness will be measured with Spectralis OCT on screening date. Postoperative examinations will be implemented in accordance with the approved investigational plan on subjects and includes: visual acuity, slitlamp examination and retinal oct imaging.
The objectives of the study is to evaluate efficacy and long-term safety of the Lucidis lens. Through this study, the objective is to obtain an up-to-date clinical evaluation of the medical device thus supplementing data from experimental trials. Clinical and functional changes in the implanted eyes among a patient population in which the opaque crystalline lens resulting from cataract was removed and replaced by a Lucidis IOL will be described.
Early cataract surgery in microcornea/microphthalmia eyes is essential to prevent amblyopia and improve visual outcomes, including stereopsis. However, despite recent advances in pediatric cataract microsurgical techniques, this surgery remains challenging owing to several intraoperative difficulties attributable to the crowded anterior segment in these small, soft, and poorly developed eyes with shallow anterior chambers, and poor pupillary dilation. In this study the investigator aim to report on the changes in the anterior segment biometric characteristics after cataract extraction in eyes with microcornea/microphthalmia with congenital cataract.
The Objective Visual Quality Analysis System (OQAS) is a new inspection technology used to objectively assess the visual quality of the human eye. The investigators use this advanced technology to evaluate and follow up cataract patients before and after surgery, and observe the incidence, severity, and treatment effects of postoperative complications such as postoperative complications, and analyze the severity and artificial The influence of lens type, postoperative time, systemic diseases and other factors on the effect of cataract surgery, in order to discover the key factors that affect the effect of cataract surgery and the management of complications, and provide a useful reference for improving the level of cataract prevention and treatment in China
