Sutureless, scleral fixated-IOLs

This was a retrospective cohort study of 112 sutureless, scleral-fixated posterior chamber intraocular lens implantations (SSFCIOL) over a four-year time period. Mean follow-up duration was 13.0 ±10.4 months. The primary indication for SSFCIOL was dislocation of IOL due to zonular...

IOL power calculation formulas for myopic eyes undergoing cataract surgery after excimer laser

The authors set out to compare the accuracy of four no-history formulas: Barrett True-K, Haigis-L, Shammas-PL, and Triple-S to calculate the intraocular lens (IOL) power in eyes with previous myopic photorefractive keratectomy or laser in situ keratomileusis, according to their...

Are corneal guttata an additional risk factor in complicated cataract surgery needing a future corneal transplant?

This registry-based cohort study from Sweden utilised data from the Swedish National Cataract Registry and the Swedish Cornea Transplant Registry. Patients who underwent phacoemulsification with a posterior intraocular lens between 2010 and 2012 numbered 192,476. Of these cases, 288 underwent...

Effects of ‘inverted U method’ Nd:YAG laser posterior capsulotomy on anterior segment and IOL tilt

The study aimed to investigate the effects of the ‘inverted U method’ Nd:YAG laser posterior capsulotomy on anterior segment parameters, decentration and tilt of intraocular lens (IOLs) and visual acuity in 76 patients with posterior capsular opacification (PCO) after previous...

Effect of long-term scleral contact lenses on corneal topography, tear film and impression cytology in keratoconus

This study of 16 keratoconus patients aimed to investigate the impact of long-term scleral contact lens (ScCL) wear on corneal curvature, corneal thickness, tear film function and ocular surface in patients with keratoconus. Corneal topography, tear osmolarity test, Schirmer 1...

Association between serum 25-hydroxyvitamin D levels and age-related cataracts

Cataractogenesis occurs as a result of ageing, smoking, exposure to UV radiation and genetic predisposition. Antioxidants can reduce the cataract risk as found in animal models and humans and vitamin D is one of them. This epidemiological study based in...

Clinical characteristics and outcomes of open globe injury

This retrospective cohort study examined consecutive open globe injuries at a tertiary referral centre over a three year period. The aim of the study was to detail the clinical characteristics of open globe injuries and to explore their association with...

Twenty-four hour IOP patterns in patients with thyroid eye disease (OO/GL)

Elevated IOP in patients with thyroid eye disease (TED) can be caused by restriction and compression of the globe by enlarged extraocular muscles, elevated episcleral venous pressure and increased mucopolysaccharide deposition in the trabecular meshwork. Although previous studies have investigated...

Cataract surgery in patients with retinitis pigmentosa

Retinitis pigmentosa (RP) is the commonest inherited cause of retinal degeneration. Posterior subcapsular cataract (PSC) develops in 41% to 90% of these patients by age 40 years. In this retrospective study, the authors have evaluated surgical outcomes in patients with...
