BACKGROUND: Toric intraocular lens (IOL) implantation can be an effective method for correcting corneal astigmatism in patients with vitreoretinal diseases and cataract. Our purpose is to report the outcome of toric IOL implantation in two cases - a patient with scleral-buckle-induced regular corneal astigmatism and a patient with keratoconus following pars plana vitrectomy. As far as we are aware, there are no reported cases of toric IOL implantation in a vitrectomized eye with keratoconus nor of toric IOL implantation in patients with scleral-buckle-induced regular corneal astigmatism...

Cataract is a major cause of visual impairment for diabetic patients. It is imperative to develop efficient therapeutic agents against diabetic cataract (DC) because diabetes confers higher risk for complications after cataract surgery. We have previously reported the role of CeCl3 loaded mesoporous silica (CeCl3@mSiO2) nanoparticles in reducing the oxidative stress of lens epithelial cells. However, the potential of CeCl3@mSiO2 in preventing diabetic cataract development remains unclear. In this study, we applied CeCl3@mSiO2 nanoparticles with a size of 87...

Descemet's membrane detachment (DMD) though uncommon in the present day scenario of advancing surgical techniques is a significant complication that requires prompt diagnosis and management. A middle-aged man presented to our hospital with poor gain of vision following cataract surgery. There was significant corneal oedema with DMD which was confirmed on anterior segment optical coherence tomography. We describe a modified continuous intraoperative-guided approach for the management of DMD in cases with oedematous hazy corneas...

Intraocular lens (IOL) is an efficient implantable device commonly used for treating cataracts. However, bioadhesion of bacteria or residual lens epithelial cells on the IOL surface after surgery causes postoperative complications, such as endophthalmitis or posterior capsular opacification, and leads to loss of sight again. In the present study, zwitterionic polymer brushes were fabricated on the IOL surface via bottom-up grafting procedure. The attenuated total reflection-Fourier transform infrared and contact angle measurements indicated successful surface modification, as well as excellent hydrophilicity...

PURPOSE: Antibiotic prophylaxis is critical to ophthalmology and other surgical specialties. We performed natural language processing (NLP) of 743 838 operative notes recorded for 315 246 surgeries to ascertain two variables needed to study the comparative effectiveness of antibiotic prophylaxis in cataract surgery. The first key variable was an exposure variable, intracameral antibiotic injection. The second was an intraoperative complication, posterior capsular rupture (PCR), which functioned as a potential confounder...

A 56-year old female patient presented to our clinic with a complaint of low vision in her right eye. Twenty-two years earlier she had undergone a scleral buckling operation in her right eye because of retinal detachment. She indicated that vision in her right eye was good after the surgery but had recently been gradually declining. Best-corrected vision acuity was counting fingers at 1 meter in the right eye and 8/10 in the left eye. Anterior segment examination revealed stage 3 nuclear cataract in the right eye...

BACKGROUND/AIMS: Cataract is an important source of visual loss in patients with uveitis. Whether or not outcomes of cataract surgery in eyes with uveitis are worse compared with non-uveitic eyes have to date been compromised by lack of reliable estimates of benefit and harm, which require data from large cohorts. METHODS: Electronic medical record data were extracted from eight independent UK clinical sites for eyes undergoing cataract extraction between January 2010 and December 2014...

Pediatric cataracts are a huge problem worldwide, and with improving techniques and technology, the surgical treatment and postoperative visual rehabilitation are improving. Despite intraocular lenses(IOLs) being the standard of care for adult cataract surgery, this issue is still somewhat controversial, particularly in young children and infants due to lack of unequivocal evidence. This review therefore summarises the findings from recent studies on the aspect of IOL implantation in pediatric eyes. Areas covered: An extensive literature search was undertaken for published articles on congenital/developmental pediatric cataracts, and IOL implantation, where literature pertinent to traumatic and subluxated cataracts was not included in the review...

Phacoemulsification followed with intraocular lens (IOL) implantation is the most effective clinical surgeries in treating cataracts. However, posterior capsular opacification (PCO), a common complication of this surgery, may cause vision decrease after surgery. PCO is mainly caused by the adhesion, proliferation and trans-differentiation of the residual lens epithelial cells (LEC) after surgery. Surface modification of IOL to reduce the LEC adhesion is of great importance in PCO prevention. Herein, surface initiated reversible addition-fragmentation chain transfer (SI-RAFT) polymerization was utilized to modify the IOL materials for generating a comb-like polyethylene glycol (PEG) brush coating on the surface...

Posterior capsular opacification (PCO) is common after cataract surgery. Recurrence is very rare after a successful Yttrium aluminium-garnet (YAG) capsulotomy in adults. We report a case of visual axis re-opacification after a successful YAG capsulotomy for PCO in an adult. A 60-year male underwent phacoemulsification with +20.0 D acrylic hydrophobic intraocular lens implantation and silicon oil removal (SOR) five months after a successful retinal detachment repair. He underwent a capsulotomy after two months of surgery; however, the visual axis re-opacified after three more months...

Purpose. To report a modified surgical strategy in the management of intraoperative floppy iris syndrome-associated iris prolapse. Methods. Prolapsed iris is left as is and a new corneal incision near the original wound but at a different site is created. Depending on the location of the original incision and the surgeon's preference, this additional incision can be used as a new port for phacoemulsification tip or can be the new site for the iris to securely prolapse, allowing for the surgery to proceed safely...
