Swiss med-tech company helps drive new ophthalmology surgery standards
Medicel, a leading producer of lens injection systems for the medical sector, has announced its new state-of-the-art intraocular lens injector, which is set to revolutionise the safety and efficiency of ophthalmology surgery and drive new standards.
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...
AC/A non-linearity
This study investigated whether or not the response accommodative convergence to accommodation (AC/A) ratio in 30 visually normal subjects is linear with lens presentation order counterbalanced. Accommodative response was measured using the Shin Nippon SRW 500 infrared autorefractor. Accommodation was...
Biometry measure after cycloplegia
The authors investigated optical biometry in an Indian paediatric population on normal and cataract paediatric eyes and studied the effect of cycloplegia on different parameters measured in these eyes. This was a prospective study of 76 eyes aged five to...
Microbiology, risk factors and outcomes of microbial keratitis in Sydney, Australia
The authors present a retrospective case series including all patients with microbial keratitis and ocular surface diseases (OSD), including dry eye, blepharitis, Stevens-Johnson syndrome and / or ocular cicatricial pemphigoid, over a five-year period between 2012 and 2016. A total...
Delayed angle closure in pseudophakia and repeated intravitreal therapy
The authors report two cases of acute angle closure many years after uneventful cataract surgery and posterior chamber intraocular lens (IOL) implantation. Both patients had neovascular age-related macular degeneration (AMD) and received regular intravitreal injections (24 and 25 injections in...
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...
Cataract extraction and microperimetry
In this study, the authors assessed retinal sensitivity before and after cataract extraction, in an effort to understand how lens opacities may affect microperimetry results in glaucoma and macular diseases. Thirty patients awaiting cataract extraction were examined and their lens...
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...
Effect of long-term RGP-CL wear on keratoconus progression
This is a retrospective study between April and December 2017, of 22 rigid gas-permeable contact lens (RGP-CL) patients (31 eyes) and 15 non-CL patients (20 eyes) who fulfilled the criteria of: 1) >3 years follow-up and 2) Scheimpflug-based corneal imaging...
Surgery technique for subluxation in Marfan syndrome
The authors evaluated the efficacy and safety of bimanual capsulorrhexis combined with sutureless scleral-fixated IOL implant in children with Marfan syndrome. Seven children (14 eyes) with subluxated lenses underwent bilateral surgery; four female, three male with mean age of 7.1...
