Filter by:The main objective of this study is to compare the effect of preoperative use of anti-inflammatory topical prednisolone acetate 1%, nepafenac 0.1% and ketorolac tromethamine 0.4% of, plus a placebo, in maintaining the intra-operative mydriasis in extraction.
Study of T-PRED(TM) Compared to Pred Forte(R)
The investigators proposed to assess the functional and anatomical outcomes of cataract and idiopathic epiretinal macular membrane extraction in combined and consecutive surgeries.
The primary objective of this study is to evaluate, for the visual correction of aphakia, the safety and effectiveness of the Calhoun Vision Light Adjustable intraocular lens (LAL) and Light Delivery Device (LDD) in treating postoperative residual refractive error by providing a stable, targeted refractive adjustment of the LAL power and lock-in treatments with the LDD.
It is planned to implant the intraocular lenses XL Stabi ZO and Invent ZO into the eyes of patients for whom a cataract operation is medically indicated. The lenses are marketed and CE certified. Their implantation is clinical routine. In the trial the accuracy of prediction of target refraction and the difference between calculated and measured contrast vision will be examined for both lens types.
The purpose of this study was to compare the effects of Vigamox and Cravit on corneal wound healing after cataract surgery.
The VIVA study is focused on Alzheimer's disease patients with a low vision due to a bilateral cataract. The aim is to study cataract surgery results on patients' autonomy, behaviour, and mood. In fact those dement elderly patients suffer from a progressive loss of superior functions, with loss of autonomy, behaviour and mood degradation, associated with physical disabilities. The work hypothesis is that a loss of sensorial functions, particularly visual, is an aggravating factor of NEURO-cognitive troubles and absence of communication with outside circle. The protocol consists in investigating superior functions, autonomy, and behaviour troubles of the participating patients, with the help of a series of neuropsychological tests used one month before and three months after cataract operation on the eye with the worst vision. Independently of the study, patients must have given an informed consent to cataract surgery. Their participation lasts 4 months+/- 1 month. The aim of the study is to evaluate whether the cataract surgery improves patients' behaviour, autonomy and mood and possibly to show evidence onf drawbacks in of such a practice.The main objective targets to cataract surgery benefice on patients suffering from both Alzheimer's disease and impeding cataract, aiming to improve behaviour troubles. The specific objective is to measure this benefice in correlation with visual acuity improvement.
This study is to evaluate the safety and effectiveness of the Bausch & Lomb Akreos TL (thin lens) intraocular lens (IOL) following implantation in adults requiring cataract surgery.
The purpose of this study is to determine if there is a difference on the penetration of betadine 5% when using lidocaine 2% jelly versus topical tetracaine 0.5% in topical cataract surgery. This will be assessed comparing bacterial colony count and species by taking swabs from the eye surface before and after the topical anesthesia has been administered.
To study the effect of Diclofenac drops or Dexamethasone drops on combined surgery of trabeculectomy and cataract surgery.
