Filter by:The purpose of the study is to demonstrate the safety and performance of the ACRYSOF® IQ EDF IOL.
The purpose is to gauge the patients' level of comfort and anxiety for sequential cataract surgeries to assess if the second experience of cataract surgery differs from the initial experience.
Cataract is the leading cause of vision loss and blindness in the world,surgery is the only available option to correct the problem and the major reasons for low cataract surgical rates include low demand because of fear of surgery, high cost of surgery and poor visual results but new research raises the hope that someday, cataracts could be cured with simple eye drops. This is the first report for preparing urea-loaded NPs eye drops for cataract therapy. Enhancement of the urea efficacy is accomplished by using polymeric NPs based on the amphiphilic block copolymer Pluronic®F-127 (PF) which is a hydrophilic nontoxic copolymer widely used as a pharmaceutical excipient for its stabilizing properties and capability to increase the solubility.
The aim of the present study is to evaluate the postoperative visual acuity for distance, intermediate and near vision as well as the cylinder correction and the patient satisfaction after bilateral implantation of AT LISA tri toric 939MP IOLs.
The study is a prospective randomised controlled study. The patients get monolateral IOL implantation of POD F GF and POD F in the contralateral eye. Both IOLs are trifocal IOLs consisting of the same optical design. The difference between the IOLs is the material (hydrophilic and hydrophobic). To decide which eye receives POD F and which eye receives POD F GF, a randomization table will be provided to the principle investigator.
Cataract, is a clouding of the lens in the eye gradually leading to reduction of the visual acuity. In most cases it can be managed with surgery, removing the own lens and replacing it with an artificial lens, intraocular lens (IOL). These lenses are made in different materials with different properties. Uveitis refers to an inflammation in the iris, ciliary body and choroid. Patients with this disease have an increased risk of developing cataract due to the inflammation itself and treatment with steroids. They also have an increased risk of complications during surgery and postoperatively. In this group the selection of IOL might be of greater importance. The aim of this prospective randomized controlled study is to compare the outcome of hydrophobic and hydrophilic intraocular lenses in patients with and without uveitis
The purpose of this study is to compare the refractive predictability (prediction error) between the Cataract Refractive Suite (CRS) and standard manual technique at one month post-operative
Cataract is an ophthalmic disease that usually affects the elderly population. Cataract surgery with phaco-emulsification is now the most frequently performed intraocular surgical procedure in the developed world. However, differences in surgical technique impact the severity of surgical trauma and post-operative recovery. The amount of post-operative ocular pain and inflammation plays a significant role in the Patient's perception of the surgical success. Several ophthalmic products have been studied in the management of post-surgery ocular inflammation and pain following cataract surgery. Corticosteroids are considered the gold standard for the treatment of ocular inflammation, and their most commonly used route of administration is the topical instillation as eye drops formulation. After topical administration of Dexamethasone, the concentration in the anterior chamber increases and declines within hours, necessitating frequent daily instillations of eye drops for several weeks. This might be associated with compliance issues, particularly in elderly Patients or in individuals with disabilities. A pharmaceutical formulation allowing for a less frequent administration could therefore be an attractive alternative. NETILDEX™ eye drops solution, containing Netilmicin Sulfate 4.55 mg (3mg/ml) and Dexamethasone Disodium Phosphate 1.32 mg (1mg/ml), is already available for Patients. A new ophthalmic gel, preservative-free formulation has been developed. This new formulation has been tested in pre-clinical animal studies and in a clinical trial. The new formulation contains Xanthan gum, a high molecular mass polysaccharide approved by the FDA in 1969 for food products. It is used in the product as viscosity enhancer and to give to the product pseudo-plastic characteristics and prolonged ocular retention time. The purpose of this trial is to show that the administration of a reduced dose of NETILDEX ™ gel 2 times a day starting on the day of cataract extraction by means of phaco-emulsification and administered until 14 days after surgery is sufficient to obtain a non-inferior efficacy of the NETILDEX ™ eye drops solution administered 4 times a day for the same period.
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.
The purpose of this study is to quantify the opacity of posterior capsule in pediatric cataract comparing two intraocular lens materials.
