Active clinical trials for "Cataract"

Since intermediate vision is becoming increasingly important in our day-to-day tasks, a new IOL was introduced (Acunex Vario) with this objective in mind. This IOL provides excellent vision at far and intermediate distances up to 60 cm and with negligible photopic disturbances compared to conventional multifocal lenses. The Alcon AcrySof IQ Vivity IOL is designed to provide continuous vision from distance to intermediate while preserving contrast sensitivity and with a monofocal visual disturbance profile. So far, there are no published studies comparing these new IOL designs that offer an extended range of vision at far and intermediate distances. Objective: The primary objective of this study is to compare the binocular uncorrected intermediate visual acuity (UIVA) at 66 cm under photopic conditions 3 months postoperatively, in a series of patients bilaterally implanted with the Vario IOL versus those bilaterally implanted with the Vivity IOL. Study design: controlled double masked, randomized, prospective clinical trial Study population: patients of 18 years or older with bilateral cataracts that require cataract surgery. Intervention: One group receives bilateral implantation with the Vario IOL and the other group receives bilateral implantation with the Vivity IOL. Main study parameters: The main study parameter is the binocular UIVA at 66 cm under photopic conditions at 3 months postoperatively. Hypothesis: The investigators hypothesise that bilateral implantation with the Vario IOL is non-inferior when compared to bilateral implantation with the Vivity IOL, with regards to binocular UIVA at 66 cm under photopic conditions 3 months postoperatively. Cataract extraction in this study will proceed according to regular cataract surgery. As with any type of intraocular surgery, there is a possibility of complications due to anesthesia, drug reactions, and surgical problems. Postoperatively, there will be one extra postoperative visit, compared to standard cataract surgery follow-up. Spectacle-independency postoperatively, without photopic phenomena, is one of the major expected benefits when treating cataract (and presbyopia) with the implantation of the Vario or Vivity IOLs.

To assess the safety and effectiveness of treatment with an intracanalicular dexamethasone (0.4mg) insert in the operating room following cataract surgery/intraocular lens implant (IOL) with or without iStent/Hydrus/Goniotomy when placed in the lower punctum compared to the upper punctum.

Effectiveness of anterior chamber drainage on the structure of the anterior chamber, the position of the intraocular lens and the shape of the corneal incision in the early stage of cataract surgery with high intraocular pressure

Purpose of this study was to evaluate the effect of presbyopic correction lens on Humphrey visual field (HVF) testing in patients with 2 models of multifocal intraocular lens (MIOL) both with and without glaucoma. All participants performed HVF testing with presbyopic collection lenses and without presbyopic collection lenses on the same occasion (5-10 minutes between the test). The mean deviation (MD) and pattern standard deviation (PSD) were compared between with and without presbyopic collection lenses, between glaucoma and non-glaucoma and between 2 models of MIOL.

To assess the safety and effectiveness of treatment with an intracanalicular dexamethasone (0.4mg) insert in the operating room following cataract surgery/intraocular lens implant (IOL) compared to insertion 1-day post-op.

The purpose of this study is to evaluate the clinical efficacy and safety of XG-102 (900µg) compared to vehicle in the treatment of subjects with inflammation and pain following cataract surgery.

The purpose of this study is to investigate visual outcomes and assess safety at 12 months (330-420 days) post bilateral implantation of the AcrySof® IQ PanOptix™ Presbyopia-Correcting IOL.

The purpose of this study is determine whether 3% diquafosol and 0.1% sodium hyaluronate are effective and safe in the treatment of patients with dry eye after cataract surgery.

Since a new generation of femtosecond lasers became available for cataract surgery in 2009, the use of this image-guided system has provided several benefits, including a reduction in phacoemulsification energy by prefragmentation of the crystalline lens, and the potential advantages of more precise corneal incisions and capsulotomy formation. However, as with any new surgical technique, femtosecond laser cataract surgery also has potential complications. Intraoperative miosis is one of the most common intraoperative complications of femtosecond laser-assisted cataract surgery, with a reported prevalence ranging from 9.5 to 32.0%.8 Significant pupillary constriction necessitates the removal of the anterior capsule flap, fragmented nucleus and remaining cortex, which is potentially associated with a higher rate of surgery-related complications.

The purpose of this study is to compare the safety and efficacy of goniotomy performed with a novel ophthalmic knife compared to trabecular bypass stent implantation in mild to moderate glaucoma subjects who are also undergoing cataract extraction with phacoemulsification (Phaco) and posterior chamber intraocular lens (PCIOL) implant.
