Implantation of diffractive trifocal intraocular lens
This study reports on 60 eyes of 120 patients who underwent routine cataract surgery followed by implantation of the trifocal IOL model Lisa tri-839MP. This is a diffractive trifocal preloaded IOL with no interruption at the haptic-optic junction, 360 degrees...

Capsule opacification, Cataract surgery, Epithelial–mesenchymal transition, Nanostructures, Prevention
Lens refilling is the replacement of the lens with a silicone polymer in an otherwise intact lens capsule. However, capsular opacification (CO), resulting in reduced visual acuity, is a major complication of these injectable accommodating lenses. Opacification is due to...
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...
Incidence and risk factors of late in the bag intraocular lens dislocation
The aim of this study was to identify risk factors for late in the bag dislocation over a 21 year period. Worldwide the incidence varies from 0.05% to 3.0%. In this Swedish study they report an increase in incidence in...
Prophylaxis for clinical macular oedema after phacoemulsification
The authors report on a retrospective cohort study looking at three different prophylaxis methods for macular oedema after cataract surgery: 1) Topical prednisolone acetate (PA) alone; 2) Topical PA in combination with non-steroidal anti-inflammatory drug (NSAID); 3) Intraoperative subconjunctival injection...
Simple approach to prevent capsule tear-out during capsulorhexis creation in hyper mature cataracts
Puncturing the anterior capsule in the anterior chamber so that the pressure falls below intracapsular tension causes the rhexis to extend out to the equator. If this develops into a tear that wraps around the entire lens it is called...
How does cataract surgery affect eyes with wet AMD?
In this retrospective cohort study the authors’ primary objective was to assess whether cataract surgery in eyes with wet age-related macular degeneration (AMD), triggered its progression. The surgical group comprised of 40 eyes versus 42 eyes in the non-surgical control...
Comparison of ketorolac 0.4% and nepafenac 0.1% for the prevention of CMO after phacoemulsification
This is a prospective randomised clinical trial study including patients older than 40 years with age related cataract and normal ophthalmic examination. The patients are randomised into three different groups and the objective of the study is to compare the...
Changes in refractive error in patients with accommodative esotropia after being weaned from hyperopic correction
This is a retrospective review of medical records of 47 patients with refractive ocular accommodative esotropia who achieved emmetropisation and orthotropia without hyperopic glasses correction and were followed up for at least three years. The objective of the study is...
Evaluation of keratometry with a novel colour LED corneal topographer
The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...
Influence of FLEx and SMILE on corneal nerve density and ocular surface
This was a prospective study designed to compare the influence of femtosecond lenticule extraction (FLEx) and small incision lenticule extraction (SMILE) on the corneal nerve density and ocular surface for myopic correction. Thirty patients underwent bilateral lenticule extraction. One eye...
