Active clinical trials for "Cataract"

This clinical study is being conducted to identify the most effective drug concentration and dose frequency of BOL-303242-X (Mapracorat) ophthalmic suspension, for the treatment of inflammation following cataract surgery.

This study is being conducted to compare the safety and efficacy of loteprednol etabonate to vehicle for the treatment of postoperative inflammation and pain following cataract surgery.

Evaluate the safety and efficacy of the Glaukos Trabecular Micro-Bypass Stent Model GTS400 using the G2-M-IS injector system in conjunction with cataract surgery vs. cataract surgery only, in subjects with mild to moderate primary open-angle glaucoma.

The primary objective of this study was to investigate the efficacy of bromfenac sodium ophthalmic solution 0.09% for treatment of post-operative ocular inflammation in subjects who undergo cataract extraction and intraocular lens implantation. The secondary objective was to investigate the safety and tolerability of the same.

This study will test the effectiveness of an intraocular lens treated with heparin in reducing or preventing inflammation after cataract surgery in patients with uveitis. Patients with uveitis (inflammatory eye disease) often develop cataracts (clouding of the lens of the eye) that can impair eyesight. Cataracts can be removed surgically, and this is usually done when poor vision interferes with adequate daily functioning, or when the lens becomes too cloudy to evaluate the level of eye inflammation in uveitis-information needed to adjust medication dosages. After surgery, vision is corrected with special eyeglasses, contact lenses, or intraocular lenses (IOL). IOLs are small, plastic artificial lenses permanently placed inside the eye. Patients with uveitis who require cataract surgery and whose eye inflammation has been controlled by medicine for at least 3 months may be eligible for this study. Those enrolled in the study will be randomly assigned to one of two treatment groups: one group will have a standard IOL implanted during cataract surgery; the other will receive a heparin-treated IOL. Before surgery, patients will undergo standard preoperative tests, including chest X-ray, electrocardiogram, blood tests and urinalysis, as well as an eye examination that includes photography of the cornea, iris and retina. Additional tests and examinations to be done at the start of the study and at periodic follow-up visits for about 1 year may include: fluorescein angiography to evaluate the blood vessels of the retina; specular microscopy to examine the surface of the IOL; cell and flare measurements to evaluate inflammation, and ultrasound to examine the back of the eye.

The primary purpose of this study is to evaluate the long-term (3 years) visual acuity and adverse event outcomes for the Clareon® Intraocular Lens (IOL). A comparison to historical safety and performance endpoint (SPE) rates as reported in the European Standard International Organization for Standardization (EN ISO) 11979-7:2014 will be conducted at one year. The secondary purpose of this study is to evaluate the visual acuity outcomes with the Clareon IOL at Years 2 and 3.

Post-operative cystoid macular oedema (CMO) is a common complication causing visual loss following routine cataract surgery. This complication is more prevalent in eyes with excessive inflammation as they heal from surgery. Prostaglandin analogues (PGA) are the commonest first line drugs used in the long-term treatment of primary open angle glaucoma (POAG)- where they reduce the pathologically high pressure in the eye. Prostaglandins are inflammatory mediators. In the post-operative care of glaucoma patients undergoing cataract surgery, there is a clinical dilemma whether to stop or continue the use of prostaglandin eye drops. Clinical practice is completely dichotomized between continuing and stopping PGA treatment in the postoperative period. There is conflicting scientific literature on the effect of PGA on the incidence of CMO; and only a single randomized control trial (Miyake K, Arch Ophthalmol 1999, 117:34-40), where the post operative regime is not applicable to present practice, compared the incidence of CMO following routine cataract surgery in POAG on PGA.

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.

The objective of the study is to evaluate the safety and effectiveness of the enVista trifocal intraocular lens when implanted in the capsular bag.

This is a prospective, non-randomised, controlled, single-surgeon, single-center post-market clinical follow up study whereby patient undergoing routine cataract surgery will have bilateral implantation of a recently introduced TGA (Therapeutics Goods Authority, Australia) approved trifocal intraocular lens FineVision Evo (PhysIOL, Liège, Belgium). The primary and secondary effectiveness data for visual acuity, defocus curves, contrast sensitivity and any adverse events will be collected.
