Does religious fasting affect intraocular pressure or retinal parameters?

Nearly one billion Muslims fast every year during the month of Ramadan. Due to the difference between the lunar and solar calendars, religious fasting time can range from 11 to 17 hours per day. This prolonged abstinence from food and...

Multicentre PCO rates in different brands of monofocal intraocular lenses

This was a longitudinal, retrospective cohort study featuring 47,754 (three years) and 20,763 (five years) eyes with age-related (≥65 year) cataract surgeries between 2010-2013 across seven UK ophthalmology clinics. The three- and five-year incidence of posterior capsular opacification (PCO) and...

An unusual case of silicone oil in the anterior chamber simulating intraocular implant

Silicone oil internal tamponade has been used for over 50 years, even prior to pars plana vitrectomy [1].Over a course of time silicone oil may migrate to the anterior chamber through the pupil. This may disperse in the form of...

Correlation between peak intraocular pressure following water drinking test and pulsed methylprednisolone therapy

Steroids have long been known to cause increased intraocular pressures (IOP) in susceptible patients. Intravenous methylprednisolone is used to treat many rheumatological conditions and one of the risks is raised intraocular pressure. It would be useful to find patients at...

Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure

The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...

Positive outcomes for premium LuxSmart™ intraocular lenses, following one-year real-world experience

Bausch + Lomb’s premium lens designed for providing distance and intermediate continuous vision with a potentially similar dysphotopsia profile as a monofocal, thanks to its Pure Refractive Optics technology Bausch + Lomb today announced positive outcomes following the one-year real-world evaluation of its premium LuxSmart™ lens, since its European launch in 2020.

Results after 1.4mm biaxial cataract surgery and implantation of a new aspheric intraocular lens

The aim of this study was to analyse the clinical outcome and higher-order aberrations (HOAs) after 1.4mm biaxial micro incision cataract surgery (B-MICS) and implantation of a new aspheric intraocular lens (IOL). A total of 157 eyes of 106 patients...

Closed-chamber haptic re-externalisation for posteriorly displaced sclerotomy and inadequate haptic tuck in glued posterior chamber intraocular lenses

This technique (online video http://jcrsjournal.org) emphasises the importance of both symmetrical and sufficient anterior placement of sclerotomies to externalise an adequate length of the haptics, which in turn provides good centration and stability of the intra-ocular lens (IOL). The authors...

Endothelial keratoplasty (EK) with anterior chamber intraocular lens (ACIOL) versus secondary posterior chamber lens (PCIOL)

This is a retrospective study of 82 eyes (23 ACIOL, 59 PCIOL) with a history of either pseudophakic (PBK) or aphakic (ABK) bullous keratopathy, who had descemet stripping automated endothelial keratoplasty (DSAEK) with retained or secondary ACIOL, or DSAEK with...

Intraocular lens technology to deliver enhanced optical performance after cataract refractive surgery

Modern cataract surgery aims to provide patients with the best possible visual outcome with the least dependence on spectacles and minimal or no complications and to treat both cataract and refractive errors with a single procedure. Phacoemulsification is the standard...

Analysis of risk factors for intraocular pressure rise following insertion of fluocinolone acetonide injection in uveitic patients

For this study, the authors analysed the pooled data from three phase2b / 3 multi-centre randomised controlled trials carried out over three years. Included patients had undergone at least one of the following treatments: 1) systemic therapy (corticosteroid / immunosuppressant...

Comparing tensile strengths of two scleral fixated intraocular lenses: CT-Lucia and MA60

The authors designed a benchtop model to measure the tensile strengths and resistance to breakage of the haptics and haptic-optic junctions of the CT Lucia 602 (Carl Zeiss, California) and AcrySof MA60 (Alcon Laboratories, Texas) IOLs. For the haptic breakage...
