Evaluation of keratometry with a novel colour LED corneal topographer

Cataract and Refractive
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...

Ophthalmology
I am regularly faced with litigation whereby the claimant’s cornea has decompensated after cataract surgery. The procedure may have been complicated but sometimes it is not. The eye may have been high risk, for example, a shallow anterior chamber with...

Anterior segment optical coherence tomography, corneal foreign body, corneal wound healing, foreign body removal
This was a prospective study of 63 eyes of 63 patients undergoing corneal foreign body (FB) removal with a 27G needle at the slit-lamp; 96.8% of the patients were men with mean age 35.8 ±11.0 years. Regarding location of FBs,...
Scheimpflug vs. OCT in measuring corneal thickness

Cornea / External Eye Disease
The authors report on the reproducibility and repeatability of corneal thickness measurements using three different Scheimpflug imaging cameras (Pentacam, Sirius and Galilei) and one Fourier-domain optical coherence tomography (OCT) system (RTvue-100). The rationale for this study is that corneal thickness...
Laser corneal refractive procedures – a review
Evolution of refractive surgery stays true to the quote of Theodore Roosevelt: “The more you know about the past, the better prepared you are for the future.” Refractive surgery is an evolving field, which thanks modern technologies for refining ideas...In conversation with Andrena McElvanney (President, MCLOSA)

Effect of trabeculectomy on corneal endothelial cell loss
5 October 2020
| Jonathan Chan
|
Glaucoma
This is a prospective study of 117 eyes for two years after trabeculectomy, to investigate the corneal endothelial cell density (CECD) by specular microscopy prior to and after surgery on a six monthly basis. At six, 12, 18 and 24...
LASIK for myopia progression
5 February 2020
| Fiona Rowe (Prof)
|
Paediatric Ophthalmology / Strabismus
The authors hypothesise that corneal reshaping with refractive surgery could have an effect on myopic progression similar to that of orthokeratology because it results in changes to the central cornea and not to the peripheral cornea. This was a retrospective...

Cataract and Refractive
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...
Corneal neurotisation with an allograft

Oculoplastics
This is the first reported use of an acellular nerve allograft for corneal neurotisation. Seven patients received a 7cm long commercially prepared acellular nerve allograft. This was coapted to a functioning supratrochlear, supraorbital or infraorbital nerve and then tunnelled to...
Silent keratitis in failed graft

Cornea / External Eye Disease
This study examined rates of asymptomatic keratitis in failed full thickness corneal grafts, which were not picked up clinically preoperatively. During a five year period 53 penetrating keratoplasties (PK) were performed for long-standing graft decompensation with stromal opacity and /...
