Filter by:Cataract surgery is one of the most common procedures performed worldwide. Astigmatism is the most common refractive disorder in adults, hence there is a high prevalence of preexisting astigmatism in cataract patients. Access to astigmatism correction during cataract surgery allows for improved visual outcomes for patients. Toric intraocular lenses (IOLs) are the procedure of choice to correct corneal astigmatism of one diopter or more in cases undergoing cataract surgery. Rotational stability is a key factor for successful outcomes with toric IOLs. Postoperative toric IOL misalignment is the major factor responsible for suboptimal visual outcomes after toric IOL implantation. The TECNIS® Eyhance Toric II 1-piece posterior chamber lens is a new toric IOL which is FDA approved and CE marked. Marketed by Johnson & Johnson Vision, it is indicated for the visual correction of aphakia and pre-existing corneal astigmatism of one diopter or greater in adult patients with or without presbyopia in whom a cataractous lens has been removed by phacoemulsification and who desire reduction in residual refractive cylinder. No study assessing the early rotational stability of the TECNIS® Eyhance Toric II IOL has been published yet.
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.
This study is a Pre-market first-in-man clinical investigation to validate performance of a hand-held femtosecond laser named CATSYS.
Selecting the appropriate surgical approach for congenital cataracts presents challenging for ophthalmologists. This prospective, randomized controlled study aims to compare the prognosis of posterior continuous curvilinear capsulorhexis (PCCC) with or without anterior vitrectomy (A-Vit) in treating congenital cataracts.
The primary purpose of the study is to evaluate the efficacy and safety of MELT-300 (Midazolam and Ketamine Sublingual Tablets) and the contribution of midazolam and ketamine components to sedation and during the surgery or ocular analgesia in participants undergoing cataract surgery with lens replacement.
Some parameters, such as a change in the optic tilt and axial decentration, can affect the optical characteristics of intraocular lenses (IOLs) in postoperative period, which leads to residual refractive errors and other complications. The stability of the intraocular lens in the eye is largely dependent on the mechanical design of its haptic support elements. Thus, the new Clareon IOL has a flat haptic with a flexible design that minimizes axial changes and allows the IOL to maintain a stable position in a given plane during compression. Currently there is no published data of the stability for Clareon AutonoMe IOL for long eyes. The purpose of the current study is to evaluate and compare the axis displacement and stability of optical tilt, visual and refractive results in patients after implantation of two different models of intraocular lenses: Clareon AutonoMe (Alcon, USA) and Hoya iSert 251 (Japan) in the long-term postoperative period (after cataract surgery).
Evaluation of the rotational stability of a new toric intraocular lens (IOL), the TECNIS Eyhance toric II.
The main goal of this study is to compare traditional cataract surgery with two new technologies: the femtosecond laser and the new Active Sentry handpiece. The femtosecond laser is used in several fields of ophthalmology and allows to automate multiple key steps of cataract surgery. The new generation of handpiece called Active Sentry has the particularity to detect the pressure inside the eye in real time and to adjust it to avoid large variations. Theses technologies would potentially increase the efficacy and safety of standard cataract surgery. This study therefore aims at evaluating the differences in cumulative dissipated energy and endothelial cell loss between femtosecond laser assisted cataract surgery with the new Active Sentry handpiece compared to standard phaco with new (Active Sentry) or older handpieces (OZil).
The purpose of this research is to assess the rotational stability of the AcrySof IQ Vivity Extended Vision Toric IOL and Refractive Visual outcome.
To determine if the intraocular pseudophakic contact lens (IOPCL), referred to as the AccuraSee, corrects residual refractive errors after cataract surgery using a plus powered lens in subjects with ocular pathology previously implanted with a Bausch and Lomb LI61AO or LI61SE monofocal posterior chamber intraocular lens (PCIOL) and to confirm its positional stability and adherence relative to the PCIOL.
