Comparison of methods of central corneal thickness measurement in glaucoma

This prospective study was done to compare the accuracy and reproducibility of central corneal thickness measured by hand-held and disc-mounted ultrasound pachymeter in glaucoma patients. Sixty-five patients were included in the study. Patients with corneal diseases, corneal astigmatism >3 diopters...

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...

Case series of toxic anterior segment syndrome

Herein we report two cases of toxic anterior segment syndrome (TASS) following uneventful cataract surgery. Both patients presented 24 hours after their uneventful operations with painless blurred vision in the operated eye. The inflammatory reaction was controlled successfully with an...

A step-by-step approach to the diagnosis and management of Sands of Sahara Syndrome

Sands of Sahara syndrome (diffuse lamellar keratitis) is a rare postoperative complication of Laser in situ keratomileusis (LASIK). Its estimated prevalence is reported to be 2-4% among LASIK cases [1], despite that, it is more likely to be encountered by...

Glaucoma patients can monitor and treat their own IOP!

Simerdip Kaur takes a look at the latest ophthalmology-related stories in the news. Headline: Glaucoma patients can monitor and treat their own IOP! It is well known that poorly controlled intraocular pressure (IOP) is a leading risk factor for glaucoma...

Is DSAEK or DMEK better for failed penetrating keratoplasty (PKP)?

This retrospective study involved 52 patients with failed penetrating keratoplasty. Twenty-eight eyes underwent Descemet membrane endothelial keratoplasty (DMEK) and 24 eyes underwent Descemet stripping automated endothelial keratoplasty (DSAEK). Data collection included demographic characteristics, number of previous corneal transplants, previous glaucoma...

How long to air tamponade after DMEK?

This interventional case series looked at the influence of different intraoperative air tamponade times on graft adherence after descemet membrane endothelial keratoplasty (DMEK). A total of 117 eyes with Fuchs endothelial corneal dystrophy (FECD) that underwent DMEK were included. Patients...

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...

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...

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...

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.
