BESTi: a new index to detect subclinical keratoconus

In this multicentre, case-control study, the authors develop a new index, named Boosted Ectasia Susceptibility Tomography Index (BESTi), to detect early cases of keratoconus. This index was derived from multiple logistic regression analysis of 22 variables of tomography scans. The...

Diagnosis and management of paediatric keratoconus

This article reviews the current literature on paediatric keratoconus diagnosis and management. Paediatric cases pose challenges as they may not vocalise unilateral changes, difficulty in obtaining reliable imaging, faster rates of progression, difficultly with contact lenses and presumed worse outcomes...

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...

Accelerated (9mW/cm2) corneal collagen cross-linking for keratoconus

This is one of many studies published / to be published on corneal collagen cross-linking that has a treatment time of 10 minutes compared to the previous Dresden protocol of 30 minutes to halt progression of keratoconus. Much has changed...

Quiz Apr/May 2023

History A 76-year-old female presented at her local district general hospital with right decreased visual acuity, glare, and foreign body sensation, in addition to longer-term dry eyes. She was otherwise well. Her past medical history included hypertension. On examination: vision...

Dramatic myopic shift due to epithelial basement membrane dystrophy

Epithelial basement membrane dystrophy (EBMD), also known as map-dot-fingerprint dystrophy, is a common anterior corneal disorder affecting approximately 2% of the population [1]. It is characterised by the abnormal maintenance of the basement membrane, resulting in protrusions into the epithelium....

Ocular Surface Disorders

This publication provides an excellent overview of ocular surface disease (OSD). Dry eye disease (DED) is the commonest OSD. There has been a recent explosion, both in terms of its diagnosis and the treatments that are available. A textbook that...

IOL power calculation formulas for myopic eyes undergoing cataract surgery after excimer laser

The authors set out to compare the accuracy of four no-history formulas: Barrett True-K, Haigis-L, Shammas-PL, and Triple-S to calculate the intraocular lens (IOL) power in eyes with previous myopic photorefractive keratectomy or laser in situ keratomileusis, according to their...

PACK-crosslinking for infectious keratitis

Corneal cross-linking with riboflavin and UV-A light (CXL) is a technology that has been initially developed to treat corneal ectatic disorders [1]. Its effect in stabilising diseases such as keratoconus was reported in numerous trials with excellent long-term outcomes and...

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...

Outcomes for IRS implantation for keratoconus

The authors report visual and topographic outcomes of intracorneal ring segment (ICRS) implantation alone or in combination with corneal cross linking (CXL) and long-term results in halting keratoconus in paediatric patients. This study was a retrospective design including 19 patients...

Long-term outcomes of deep anterior lamellar versus penetrating keratoplasty for keratoconus

This is a retrospective consecutive and comparative case series of keratoplasties (228 deep anterior lamellar keratoplasties (DALKs) and 274 penetrating keratoplasties (PKs)) in a single centre by one surgeon in France, between 1993 and 2021. Graft survival was 96.7% at...
