Topography based keratoconus progression after corneal collagen cross-linking

Case 1 describes a 35-year-old man with progressive keratoconus (PK). His best corrected visual acuity (BCVA) was right 20/80 (-5.25/-7.75 x 85) and left 20/20 (+4.75/-5.00 x 90). His Ks were right 36.32/48.02 D and 41.15/46.41 D. Right central cornea...

Heidelberg Engineering expands its anterior segment imaging portfolio with Heidelberg RCM

Heidelberg Engineering today announced the expansion of its anterior segment imaging portfolio with Heidelberg RCM, marking the company's return to the field of in vivo corneal confocal microscopy. The new device extends Heidelberg Engineering's ophthalmic imaging offering with high-resolution, cellular-level...

Principles of contact lens fitting in keratoconus

Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...

Quiz Aug/Sep 2025

History A 78-year-old female presented with bilateral, painless, progressive blurring of vision over five years, photophobia and increasing glare. Her past medical history included a known diagnosis of monoclonal gammopathy of undetermined significance (MGUS). On examination, vision in the left...

Anaesthetic drops abuse

A 67-year-old retired female nurse presented with persistent, bilateral, non-healing (>6 weeks) corneal ulcers and stromal ring infiltrates (Figures 1 and 2). The epithelial defects were the result of chemical burns caused by her contact lenses which had been stored...

Resurfacing the ocular surface

The ocular surface (OS) is an anatomical and functional unit made of the tear film, the conjunctival, limbal and corneal epithelium, the lacrimal, mucous and meibomian glands and the lids and blink reflex. The tear film is composed of a...

AI detects eye changes that lead to sight loss in young people

Use of Artificial Intelligence (AI) can accurately predict when young people with the sight- threatening eye condition kerataconus need treatment to stabilise the cornea and prevent loss of vision. Developed by researchers at Moorfields Eye Hospital and UCL Institute of...

Corneal molecular and cellular biology for refractive surgeon

This is an interesting literature review that looks into the recent advances concerning the corneal molecular and cellular processes that are involved in the wound healing response after excimer laser surface ablation and LASIK surgery. It talks about the complex...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...

Sight loss to styling the stars – how Moorfields gave JJ a second chance

Thanks to surgery at Moorfields Eye Hospital, JJ Savani has had vision restored in one eye, but this is only half the story – his life has been completely transformed; and as a thank you, JJ is giving all author...

Outcomes of corneal cross-linking in paediatric patients compared to fellow untreated eyes

This retrospective cohort study evaluated long-term visual, refractive, topographic and safety outcomes of corneal cross-linking (CXL) in patients younger than 18-years-old with keratoconus. The study included all consecutive paediatric patients who underwent epithelium-off CXL treatment for keratoconus at the study...

Management of traumatic corneal perforations with anterior lamellar techniques: The mini-DSAEK

The authors present the first case report in which a mini (reduced diameter) Descemet’s stripping automated endothelial keratoplasty (mini-DSAEK) has been used to manage a traumatic corneal perforation. A 69-year-old male presented with 6/36 best spectacle-corrected visual acuity (BSCVA) and...
