The risks of not using iodine during intravitreal injections

Intravitreal injections are frequently administered to patients with wet macular degeneration, retinal vein occlusion or diabetic eye disease. During the injection procedure, povidone-iodine drops are used to disinfect the ocular surface, which reduces the risk of post-injection infection in the eye (endophthalmitis – which is very rare but can cause significant visual loss if it… Read More

Scharioth Macula Lens – magnifier in the eye

The Scharioth Macula Lens (SML) is a magnifying add-on lens implant, designed for eyes which have already had cataract surgery and which also have macular disease such as macular degeneration. It aims to improve reading vision and near visual function significantly, by enabling reading of small print at short distances of around 15cm. The inventor… Read More

Laser-assisted cataract surgery – visual outcomes

In recent years femtosecond lasers have been used in a small number of centers to assist in cataract surgery, with theoretical benefits including more precise creation of corneal incisions and the anterior capsulotomy. However the majority of surgeons have failed to see this translate into any meaningful visual benefit for the patient, and indeed the… Read More

Epimacular brachytherapy (X-rays) for wet macular degeneration

This novel treatment was designed for wet macular degeneration, and involves vitrectomy surgery combined with a device which shines radiation on the macula, in order to try to reduce the frequency of injections required. However after 12 months of treatment, it was not found to be effective, and in fact visual outcomes were worse when… Read More

Avastin (bevacizumab) for wet AMD does not increase risk of stroke or heart attack

One of the largest studies to date to examine the relationship between single or multiple intravitreal injections of Avastin (bevacizumab) for wet macular degeneration, studying several thousand patients from British Columbia in Canada, has not found any increased risk of myocardial infarction (heart attack) or stroke in patients receiving the injections: This is obviously… Read More

Routine use of non-steroidal drops after cataract surgery

There are two types of eye drop that can be used to control eye inflammation following cataract surgery – steroid drops, and non-steroidal drops (the latter of which are the eye drop equivalent of something like ibuprofen). Of the two classes, steroid drops are more effective (potent) and almost all surgeons routinely prescribe them following… Read More
