Filter by:Aspheric intraocular lenses can effectively reduce higher-order aberrations and improve contrast sensitivity function after cataract surgery.
The purpose of this study is to determine whether intraocular lidocaine increases patient comfort during the different stages of MSICS while under topical anesthesia.
The purpose of this study is to compare the efficacy of olive tip cannula to the standard Steven's cannula in performing subtenon's anesthesia for patients undergoing cataract surgery.
This study will determine the incidence and severity of dry eye in patients undergoing cataract surgery as determined by grade on the International Task Force (ITF) scale.
To determine the differences in intra-operative complications, surgical duration, fluid usage, corneal thickness and endothelium cell density in eyes undergoing microcoaxial phacoemulsification (MCP) either with Torsional or longitudinal ultrasound during the surgery and at post-operative day 1, 1 month and 3 months.
Given the availability of aspheric diffractive IOLs with varying negative spherical aberration it may be feasible, by selecting the best fit IOL, to minimize aberrations and thereby maximize visual performance.
This randomized controlled trial compares two regimens of topical therapy: - tobramycin 0.3% - dexamethasone 0.1% (TobraDex®, Alcon), one drop four times/day - combination of tobramycin 0.3% - dexamethasone 0.1% (TobraDex®, Alcon), one drop four times/day, plus Ketorolac tromethamine 0.5% (Acular®, Allergan), one drop three times/day. The topical treatment is administered for 28 days after phacoemulsification. Patients are independently assessed by two ophthalmologists. On day 28, patients are evaluated for - corneal edema - conjunctival redness - anterior chamber reaction. Moreover, the cases necessitating continuation of treatment are compared in the two groups on day 28 and 42.
The purpose of this study is to determine if intraocular infusion of low-molecular weight heparin (enoxaparin) influences postoperative inflammation following pediatric cataract surgery with intraocular lens (IOL) implantation.
Dropping of nucleus is a common complication during cataract extraction by phacoemulsification. The investigators describe a new technique to retrieve the dropped nucleus by using an instrument called Pars Plana Levitator (ASICO-LLC, USA).
The purpose of this study is to evaluate the safety and effectiveness of a new opthalmic viscoelastic material for the use in cataract surgery. The new viscoelastic will be compared to a currently marketed viscoelastic material.
