Active clinical trials for "Cataract"

The use of a femtosecond laser in cataract surgery that gives equivalent or improved results comapred to conventional phaco-emulsification surgery.

To investigate the safety and efficacy of a heparin surface-modified intraocular lens in patients with uveitis undergoing cataract surgery. To evaluate the safety and efficacy of intraocular lens implantation in patients with severe uveitis.

Objective: To compare intraocular pressure lowering effect of combined sclerotomy ab interno with phacoemulsification and phacoemulsification alone, in primary or secondary open angle glaucoma patients. Study design: Prospective, randomized, case- control interventional surgical trial

The incidence rate of postoperative capsular opacification (PCO) in children after cataract surgery is reported to be as high as 100%, while timely Nd: YAG laser posterior capsulotomy is effective to treat visual axis opacification (VAO) caused by PCO. Therefore, long-term follow-up, timely diagnosis and treatment is important to improve patient's outcome. The major and central part of lens is easy to be observed through a dilated pupil. Especially, opacification in the lens and/or lens capsule is distinctive showing as "white" on the "black" background. The characteristic features of the disease and advances in photographic technique with mobile phone make it possible for patients and/or their guardians to monitor the progress of cataract or PCO with mobile application in a "self-help" manner under non-clinical settings.

The purpose of this study is to determine the refractive outcomes and optimize the clinical features of a new intraocular lens intended to treat the senile cataract.

Advances in cataract surgery and premium IOLs have allowed the ophthalmologist and optometrist to embrace the fact, as with Lasik patients, that refractive cataract surgery can allow their patients to be potentially free or less dependent on glasses. However, fewer than 13% of all patients undergoing cataract surgery today choose a premium IOL and of these approximately 5% are presbyopic IOLs. The need for greater optometric involvement in cataract surgery is necessary as demand for cataract surgery increases with the population ageing. According to a recent American Optometric Association survey, optometrists diagnose, on average, 13 cases of cataracts per month and refer or co-manage about half of them that are sent for surgery. Since patients base their decision and selection primarily on doctor recommendations, it is incumbent on the optometric community to be well informed on the benefits of the Advanced Technology IOLs. There is currently no data that has been collected comparing Advanced Technology IOLs and their clinical outcome and acceptance rate among patients co-managed with optometrists. This pilot study will study the subjective visual symptoms, spectacle independence at various distances and patient satisfaction after bilateral implantation of the Tecnis Symfony Extended Range of Vision Advanced Technology IOL in this co-managed care environment. The primary assessment tool will be a Non-directed Patient Satisfaction and Symptoms Questionnaire. Initial questions would include; "How satisfied are you with your spectacle-free vision at distance/intermediate/near?", "Would you choose the same lens again?" and "Would you recommend the same lens to your relatives and friends". Similarly, with regard to Photic phenomena / visual symptoms, we would ask "Do you experience any problems with your vision?" and only follow up with specific questions on severity once the patient volunteers a specific symptom.. The surgery form will include a question determining the surgeon's satisfaction with the individual Symfony lens implantation. At last visit the optometric investigator will be asked about his satisfaction with the performance of the Symfony lens. This will allow monitoring of any progression of satisfaction as more experience with the lens is obtained.

The complicated schedules for administering topical steroid eye drops combined with forgetfulness and physical difficulties instilling the drops may compromise compliance; which in turn could increase the risk for secondary complications such as PME post-cataract surgery, especially in a high-risk diabetic population. Dextenza, a sustained- release steroid insert, could help preclude adherence difficulties and provide better bioavailability, being as effective as, or more effective than steroid drops in preventing PME. The aim of this study is to assess the incidence of PME in diabetic patients undergoing cataract surgery when comparing the Dextenza insert to topical prednisolone acetate 1% drops.
