Filter by:To compare the relative effectiveness of the Imprimis Dropless™ (TriMoxiVanc) intraocular solution with the Less Drops™ topical formulation of PredMoxiKeterolac (given for the first week post op) followed by PredKeterolac (given for weeks 2 to 4 after surgery). The hypothesis is that the "dropless" regimen will be non-inferior to the "less drops" regimen in terms of post-operative IOP changes, post-operative healing, and visual quality.
The objective of the study was to evaluate the safety and efficacy of OTX-DP (dexamethasone insert) 0.4 mg for intracanalicular use when placed in the canaliculus of the eyelid for the treatment of post-surgical inflammation and pain in subjects who had undergone cataract extraction with intraocular lens implantation
Posterior capsule opacification (PCO) and glistenings development is among the primary reasons for sub-optimal visual capacity following cataract extraction surgery. Primary objective of this study is to evaluate the incidence of PCO and glistenings of the popular envista MX-60 intraocular lens (Bausch + Lomb) in a random sample of cataract patients who underwent phacoemulsification at least 1 year prior to their enrollment at the study
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.
This study will compare cataract patients before and after phacoemulsification. Evaluations will be performed before and 1 and 3 months following cataract surgery, including measurement of tear film lipid layer thickness, tear film break up time, Schirmer test, corneal and conjunctival fluorescein staining, examination of lid margins and meibomian glands, and the Ocular Surface Disease Index.
This prospective, randomized, clinical trial looks to compare children undergoing congenital cataract surgery with intraocular lens (IOL) implantation in terms of visual axis obscuration as well as postoperative complications such as glaucoma, inflammation and IOL centration when IOL fixation is performed using two different techniques : 1) conventional in the bag IOL implantation with anterior vitrectomy, and, 2) posterior optic capture of the IOL through the posterior capsulorhexis without any vitrectomy. 61 eyes of 61 children randomized to receiving IOL implantation using one of the two techniques will be followed up until 12 months postoperatively.
The objective of the study was to evaluate the safety and efficacy of OTX-DP (dexamethasone insert) 0.4 mg for intracanalicular use when placed in the canaliculus of the eyelid for the treatment of post-surgical inflammation and pain in subjects who had undergone cataract extraction with intraocular lens implantation
Age-related cataract is the main cause of impaired vision in the elderly population worldwide. The only treatment that can restore functional visual ability is cataract surgery where the opacified crystalline lens is removed by phacoemulsification and an artificial intraocular lens is implanted into the remaining capsular bag. Cataract operations are generally very successful, with a low risk of serious complications. The most common reason for impaired vision after uneventful cataract surgery in otherwise healthy eyes is the development of posterior capsule opacification (PCO). PCO is a physiological change (thickening, opacification and clouding) of the capsular bag expected after cataract surgery, because the lens epithelial cells (LECs) undergo hyperplasia and cellular migration. PCO is treated with Nd:YAG capsulotomy, a quick outpatient procedure that uses a laser to open a central hole in the posterior capsular bag. Modifications in IOL design and material lead to a decrease in the incidence of PCO. During the past two decades, refinements in surgical technique were made resulting in today's small incision phacoemulsification surgery. Nowadays a multitude of microincision IOLs are available, many of them similar but of course with some differences in regard to the chemical composition of the acrylic material and the IOL design. The purpose of this study is to compare the development of posterior capsule opacification (PCO) and the frequency of treatment between two different microincision IOLs over a period of 2 years.

Although contemporary cataract surgery has made tremendous strides in technological advancement, posterior capsular opacification (PCO) is still the most frequent long-term complication leading to decreased visual functions and thereby dissatisfying results. A great deal of effort has been made to develop new ways to prevent the formation of PCO. A key factor, widely discussed in literature, is the material and design of the intraocular lense (IOL) edge that can lead to PCO prevention. It is still not clear whether the sharp-edged IOL produces less PCO because of its optic geometry alone or whether the biomaterial contributes to the inhibition of PCO. With the clinical introduction of the single‐piece acrylic hydrophobic IOLs with some optic and haptic design differences compared with three‐piece acrylic hydrophobic IOLs, it has become possible to determine the influence of IOL material and design on PCO prevention. It is well established that the development of PCO is a dynamic process and that a longer follow-up time is correlated with a higher degree of PCO. So far, there have been prospective clinical studies on the clinical results of single and three‐piece acrylic hydrophobic foldable IOLs. However, the question as to as to whether the PCO further increases or becomes stable or regresses on a long-term basis has not yet been answered. Since there is paucity of available literature that prospectively evaluates the development of PCO with the implantation of the single-piece SN60AT hydrophobic acrylic IOL on a long-term basis, the investigators decided to observe the degree of development of PCO at 5 years after cataract surgery.
