Effect of preservative free fluoroquinolones on human corneal epithelial cells in vitro

Fluoroquinolones, including second generation (ofloxacin and ciprofloxacin), third generation (levofloxacin and tosufloxacin) and fourth generation (gatifloxacin and moxifloxacin), are a group of bactericidal agents used to treat multiple ocular infections. The third and fourth generation fluoroquinolones have enhanced Gram-positive activity...

Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

The results of the last survey Feb21

Once again, I am grateful for the responses and read the results with interest. I am always surprised by the amount of practice variation I see. I fully accept there is art in what we do and there is no...

Portable corneal topography – exploration of a prototype

Ophthalmic imaging devices, such as corneal topographers, are not widespread in the developing world. A small device that connects to a smartphone might be a solution to improve developing nation access to corneal imaging. I recently had the opportunity to...

1/3 UK considering laser eye surgery but majority unaware it's non-reversible and affects night vision

National eye health survey shows a third of UK are considering laser eye surgery but vast majority are unaware it is non-reversible and how it can affect night vision.

Principles of management

Whatever section of pathology is to blame and wherever it strikes, the aim of treatment is always the same. Find the cause if you can. Establish the effects of the cause. Halt the pathological process if you can. Reverse its...

A simple technique for managing eyelid retraction in a patient with an exposed Boston type 2 keratoprosthesis (Kpro)

The article describes a patient with mucous membrane pemphigoid and a Boston type 2 Kpro. In the early postoperative period (one week) inferior skin retraction was noted with exposure of the Kpro and carrier cornea. The exposure was managed by...

Nano-ophthalmology paves a new path in the future of eyecare

Introduction The treatments of ocular conditions in the field of ophthalmology varies from topical to surgical procedures. The field of nanotechnology is one of the fast-growing fields of medicine, which plays an important role in turning the impossibilities of the...

The results of the last survey Apr22

The answer to the first question was interesting in that it seems an increasing number of units are doing same-sitting bilateral cataract surgery. It is becoming accepted practice and mainstream. Immediately sequential bilateral cataract surgery (ISBCS) involves performing phacoemulsification with...

Late stromal rejection in DALK

This case series reported on late stromal rejections in eyes after uncomplicated deep anterior lamellar keratoplasties (DALKs). Four eyes of three patients experienced episodes of isolated stromal rejection 33 to 46 months after surgically uncomplicated DALKs and a minimum of...

Fusarium keratitis in a patient with alcohol dependence

Treatment of fungal keratitis secondary to the Fusarium species remains a challenge. Although relatively more common in warmer climates, this corneal infection is rare in the UK. Most cases have been reported in farmers and are often preceded by trauma....

Corneal crosslinking in pellucid marginal degeneration

Fourteen studies were included in this first review examining the use of corneal-crosslinking (CXL) to treat pellucid marginal degeneration (PMD). PMD is a bilateral, non-inflammatory corneal thinning disorder characterised by inferior peripheral corneal thinning 1-3mm from the limbus in the...
