Filter by:The Hanita CleaRing device is an intraocular implant designed for inhibition of PCO leading to reduction in the Nd:YAG treatment rate. The device is implanted into the capsular bag after the extraction of the crystalline lens and prior to implantation of the IOL. The device is manufactured by Hanita Lenses from a hydrophilic acrylic co-polymer which is being used for the production of Intra-ocular lenses.
The purpose of this study is to verify the post-market safety of the IC-8 Apthera IOL after the treatment of posterior capsular opacification (PCO), an expected complication related to IC-8 Apthera IOL implantation.
Cataract surgery is one of the most frequently performed surgical interventions worldwide. The microscope light-induced retinal toxicity after cataract surgery has been described in several reports even in short procedures; however, this potential toxicity has not been evaluated by objective criteria. Indeed, this retinal phototoxicity would be increased for patients with mild macular diseases such as early stages of AMD (Aged Macular Degeneration) (ie: drusen) which are frequently associated in elderly patients with cataract. The aim of the study will be to assess the potential functional macular effects by focal and multifocal ERG after cataract surgery with NGenuity by comparison to Standard Operating Microscope (SOM). This study would particularly address eyes at risk for macular toxicity like patients with early or intermediate AMD
In case of instability or rupture of capsular bag occurs during cataract surgery, Yamane technique is one of the options to fix intracocularlens' haptics. Yamane technique uses a double-needle technique that seamlessly fixes the haptics intrascleral by creating a scleral tunnel. Aberrations, IOL tilting or even dislocations might occur and influence the final outcome of IOL implantation. The aim of this study is the evaluation of the postoperative tilt of Kowa PU6AS using Yamane technique. Furthermore of the corrected and uncorrected visual acuity and the anterior chamber depth are being developed.
A cataract is the clouding of the natural lens in the eye and is very common as when getting older. A cloudy lens makes it difficult to see. A cataract is treated by removing the cloudy lens and replacing it with an intraocular lens (known as an IOL). The goal of this clinical trial is to determine if the Eyedeal® IOL can be safely implanted in a subject's eye and if it can replace efficiently the natural lens. Subjects will be asked to attend a total of seven visits for this study for a period of 12 months after surgery.
Multicenter, randomized, evaluator-blinded clinical trial compared to Prednisolone acetate, 1% in the treatment of inflammation and pain after cataract surgery in pediatric population. This study will assess the safety of Clobetasol propionate ophthalmic nanoemulsion, 0.05% to that of Prednisolone acetate, 1% when administering one drop four times a day (QID) for 14 days followed by a tapering period of 14 days after cataract surgery.
The investigators aim to compare the visual performance of the most recently introduced extended depth of focus intraocular lenses ; AcrySofTM IQ VivityTM and TECNIS SynergyTM ( an extended depth of focus IOL ) regarding the range of vision (using defocus curve ) , contrast sensitivity( through the modulation transfer function curves ) and their effect on ocular aberrations as the ivestigators believe that proper study of these aspects could influence the investigators choice and guidance to the cataract patient about the most suitable presbyopia correcting IOL .
The most prevalent long term consequence of cataract surgery in both phacoemulsification and extracapsular cataract excision is posterior capsular opacification (PCO) PCO occurred in 11.8 percent of patients one year after surgery, 20.7 percent in three years, and 28.4 percent in five years . It causes lower visual acuity, decreased contrast sensitivity, stereoscopic vision, increases glare and monocular diplopia. The pathogenesis of PCO is dependent on the growth of lens epithelial cell remnants in the intracapsular region. Continuous curvilinear capsulorhexis, good hydro dissection, efficient removal of cortical and lenticular epithelial cells, in-the-bag IOL implantation, and the use of single-piece acrylic sharp edges IOLs are all factors in PCO avoidance. Intraoperatively, anti-metabolites such as 5-fluorouracil and mitomycin C may also be utilized. Fortunately, the overall prevalence of PCO and the using of neodymium-yttrium-aluminum-garnet (Nd: YAG) laser posterior Capsulotomy rates have dropped from 50% to fewer than 10% now The standard therapy for PCO is now Nd: YAG laser posterior capsulotomy, which has a success rate of more than 95%. The neodymium: yttrium-aluminum-garnet (Nd:YAG) laser, with a wavelength of 1064 nm, is a solid-state laser that may destroy ocular tissues by achieving optical breakdown with a brief, high-power pulse .Ionization or plasma production occurs in the ocular tissue as a result of optical breakdown. This plasma production subsequently generates acoustic and shock waves, which destroy tissue. Because of its cost-effectiveness, speed, and lack of invasiveness, it is the chosen treatment option in PCO. However laser capsulotomy is not free of complications including transient intraocular pressure (IOP) elevation, hyphema, uveitis, cystoid macular edema, and retinal detachments that occur most frequently in the first few months . Apart from the afore mentioned biological complications, mechanical effects of laser capsulotomy such as pitting of IOL, dislocation of IOL into the vitreous, and shift in the position of IOL have also be reported Displacement of the IOL following laser capsulotomy, which may be impacted by the capsulotomy size , might hypothetically modify the effective power of the IOL as well as the patients' refractive state may be altered . However, with the exception of one research that demonstrated a hyperopic shift after Nd:YAG laser capsulotomy , most prior investigations failed to show a significant change in refraction before and after Nd:YAG laser capsulotomy . According to earlier study , the size and form of Nd:YAG laser capsulotomy, the energy utilized in Nd:YAG laser capsulotomy, and the designs of IOL did not alter the post-laser refractive state. It is still unknown if the time of laser capsulotomy affects the refractive and visual prognosis of patients after Nd:YAG laser capsulotomy. Because the IOL would continue to rotate for at least 6 months following cataract surgery, Any considerable change in IOL position might result in a change in the patient's refractive state, necessitating corrective lens prescriptions
To analyse quality assurance after cataract surgery by assessing discomfort and other symptoms via telephone interviews either in the evening of the day of the surgery or 1 day after surgery versus no additional call after surgery.
The current postoperative cataract surgery eye drop regimen used at Zuckerberg San Francisco General Hospital (ZSFG) is a significant burden for its patient population, contributing to high rates of non-adherence and the development of postoperative complications. The investigators propose to replace this complex regimen with a single administration of intraocular antibiotic and subconjunctival steroid at the time of surgery. This pilot study will obtain the preliminary data required to eventually fully evaluate this innovation in postoperative care in a safety-net population with respect to postoperative outcomes, patient compliance, and patient and caregiver satisfaction.
