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...

Treatment of infantile cataract with secondary IOLs

The authors examined whether secondary IOL insertion is helpful in the successful treatment of monocular infantile cataracts. Eleven children were reviewed: eight with cataract extraction at one to four months of age and three at five to seven months of...

Risk factors for NTG in a young Korean population

Previously known ocular and systemic risk factors for normal tension glaucoma (NTG) include myopia, peripapillary atrophy, disc haemorrhage, migraine, obstructive sleep apnoea, thyroid disease and cerebral infarction. However, most NTG risk factor studies have examined patients aged 40 years and...

Phakic iris clip lenses and endothelial cell loss

This retrospective observational study included long-term results on endothelial cell losses in highly myopic eyes, which underwent phakic iris-clip lens implantations. Included in the analysis were 113 eyes with mean preoperative spherical equivalent (SEQ) of -14.67 +/- 5.15 Diopters (D)....

Sleep positions and the effect on IOP

The authors describe a study to determine if sleeping at a 20 degree head up position decreases nocturnal IOP compared with lying supine in patients with and without glaucoma. They recruited 30 patients (60 eyes) 15 with glaucoma and 15...

Long-term outcomes following surgery for traumatic cyclodialysis clefts

This retrospective case series evaluated the long-term visual prognosis and intraocular pressure control following surgical treatment of traumatic cyclodialysis clefts. Cyclodialysis clefts result from the disinsertion of the longitudinal ciliary muscle fibres from the scleral spur and occur as a...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Intraocular pressure reduction after cataract surgery

Several studies have shown the efficacy of cataract surgery in lowering intraocular pressure (IOP), especially in angle closure glaucoma compared to open angle. A total of 156 eyes of 109 patients (without glaucoma or with medically controlled glaucoma) were included....

IOL effect on refraction

The authors aimed to evaluate the effect of age at primary intraocular lens (IOL) implantation on the rate of refractive growth during childhood. This was a retrospective study of 296 eyes of 219 patients. Forty-six met inclusion criteria; 28 unilateral...

Effect of blue-light filtering intraocular lenses on age-related macular degeneration

This is a retrospective cohort study evaluating whether blue-light filtering (BLF) intraocular lenses (IOL) offer prophylaxis for neovascular age-related macular degeneration (nAMD). The study included 11,397 eyes of 11,397 patients with a mean age of 75.4 ±8.3 years that underwent...

Sequential scleral fixated IOL followed by DSAEK better than simultaneous approach

This prospective randomised comparative study compared a simultaneous approach of combined scleral-fixated intraocular lens (SF IOL) and Descemet-stripping automated endothelial keratoplasty (DSAEK) compared to intrascleral haptic fixation technique, followed by DSAEK in a sequential fashion with an interval of at...

Clinical outcomes of a supplementary sulcus IOL

In this retrospective study, the authors examined 31 eyes of 20 patients who had received a supplementary trifocal sulcus IOL in addition to a ‘bag-in-the-lens’ IOL. Implantation of a ‘bag-in-the-lens’ IOL requires the creation of anterior and posterior capsulotomies, followed...
