Filter by:Phacoemulsification in eyes with a shallow anterior chamber (ACD < 2.2mm) presents with problems of safe access to the cataract and increased vulnerability of the endothelium and a higher tendency of complications such as descemet's detachment and iris prolapse. A shallow anterior chamber is also responsible for the high incidence of glaucoma and postoperative complications after cataract surgery. Femtosecond assisted cataract surgery has made cataract surgery safer and more predictable. The effective phacoemulsification time and intra-operative manipulation is greatly reduced in FLACS. However phacoemulsification still remains the most widely performed cataract surgery around the world. Post-operative outcomes after phacoemulsification in patients having shallow anterior chamber have been extensively reported in literature over the years. There is no head to head comparison in terms of intraoperative performance and post-operative outcomes between FLACS and phacoemulsification in eyes with shallow anterior chamber. The aim is to compare the intra-operative performance and post-operative outcomes in eyes undergoing femtosecond laser assisted cataract surgery versus eyes undergoing phacoemulsification in eyes having shallow anterior chamber. The study will bring an understanding on the question: Do patients undergoing Femtosecond laser assisted cataract surgery behave differently from those undergoing phacoemulsification?
Although phacoemulsification in previously vitrectomized eyes is a relatively safe procedure comparing with extracapsular cataract surgery, it is still more challenging than in eyes without previous vitrectomy because of the anatomical differences after PPV. Intraoperative difficulties such as abnormal anterior chamber deepening, unstable posterior capsules, and weakened zonules have been reported. The investigators aim to evaluate the efficacy and safety of a new simple iris hook assisted maneuver in phacoemulsification, then compare the incidence of intraoperative and postoperative complications of this technique with traditional phacoemulsification and phacoemulsification with 25-gauge vitreous irrigation. The latter two surgery methods are currently popular for cataract in vitrectomized eyes.
The purpose of this study is to evaluate the efficacy of Saturno II association on the control of ocular inflammation post-phacoemulsification
The purpose of the study was to evaluate the visual acuity outcomes when using the Optiwave Refractive Analysis (ORA) with VerifEye+ and Barrett Toric Calculator for calculating intraocular lens (IOL) power and axis in subjects requiring cataract surgery and implanted with a toric IOL in both eyes.
To compare the use of a compounded eye drop containing an antibiotic, a non-steroidal and steroidal anti-inflammatory to standard of care that is the use of 3 different topical medications to prevent inflammation and infection after routine cataract surgery.
This study will assess the bioequivalence of Loteprednol Etabonate and the reference listed drug (RLD)
The purpose of the study is to investigate if a novel instrument called a Binocular Optical Coherence Tomographer (OCT) may resolve many of the issues with the assessment of patients with cataract.
This study evaluated visual outcome after cataract surgery with bilateral implantation of either a diffractive - refractive (hybrid) multifocal intraocular lens (MFIOL) or monofocal intraocular lens (IOL) as a control grup.
A Study to Document the Safety and Effectiveness of a New OVD When Compared to a Control OVD
The objective of this study is to evaluate the safety and effectiveness of an investigational IOL in providing a range of vision as compared to a commercially available trifocal IOL in subjects undergoing cataract extraction and IOL implantation.
