Scheimpflug vs. OCT in measuring corneal thickness

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...

Effect of trabeculectomy on corneal endothelial cell loss

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...

In conversation with Andrena McElvanney (President, MCLOSA)

We spoke to Andrena about MCLOSA's annual meeting this November, key developments in cornea and external eye disease, and plans for the association’s 30th anniversary. Andrena McElvanney (top, second from right) and the OSI council members. The Medical Contact Lens...

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...

LASIK for myopia progression

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...

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...

Intraocular lens choice in patients who have undergone previous corneal refractive surgery

Patients who underwent vision correction in their 20s to 40s are now entering their 50s and 60s, the typical starting age for cataract development [1]. Consequently, ophthalmologists are increasingly encountering patients whose corneal profiles have been surgically altered, requiring advanced...

Silent keratitis in failed graft

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 /...

Corneal neurotisation with an allograft

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...

Complications of limbal stay sutures

There is limited literature describing complications at the limbal suture site. The authors describe two cases with postoperative complications due to use of intraoperative limbal stay sutures. Each case had strabismus surgery at other centres but with presentation to the...

Cataract surgery in corneal disease

Cataract surgery in the presence of corneal disease presents multiple challenges, from determining whether symptoms are lenticular or corneal in origin, to decisions regarding timing of surgery, intraocular lens (IOL) power calculation, IOL selection, surgical technique and perioperative care. Realistic...

Amnion-assisted conjunctival epithelial redirection (ACER): Enhancing stem cell transplantation treatment of total limbal stem cell deficiency

An exploration of Professor Harminder Dua’s recent work using a technique called amnion-assisted conjunctival epithelial redirection (ACER) to aid the success of conjunctival-limbal grafting procedures. ACER provides a refined way to use amniotic membrane (amnion), such as Omnigen® (NuVision® Biotherapies,...
