People, whether they are the patients, co-workers, or just a stranger re-affirm why some people are still in the field of patient care. They give the opportunity to "care."

An animal study evaluating the safety of intravitreal antiVEGF agents found no evidence of retinal toxicity with repeat dosing based on electroretinography and histologic evaluation. Retinal penetration and pharmacokinetics were also investigated.

Daniel S. Durrie, MD, explains corneal hysteresis as measured with the Ocular Response Analyzer (ORA, Reichert) and why he believes further research with the ORA may enhance understanding of corneal biomechanics.

Supplementation with omega-3 fatty acids, omega-6 fatty acids, and fish oils in patients with dry eye probably will decrease the overall inflammatory state of the eye based on subjective evidence, but objective placebo-controlled trials should be conducted to validate this recommendation.

Two new instruments designed by Y. Ralph Chu, MD, and available from Katena Eye Instruments are useful aids for cataract surgeons performing limbal relaxing incisions.

A set of four instruments for cataract surgery (Devgan Cataract Set, Bausch & Lomb Storz Instruments) simplifies the needs of surgeons.

The new Descemet stripping automated endothelial keratoplasty transplantation technique in which the surgeon pulls the donor cornea through without folding, rather than pushing it with the forceps, helps to prevent damage to the endothelial. ASICO's forceps have a firm grip without sharp points and a single shaft to easily maneuver in a small area.

A proprietary IOL cutter (Packer/Chang IOL Cutter, Microsurgical Technology) is a micro-scissors that can be inserted through a paracentesis incision while the surgeon holds the optic with a forceps through the phacoemulsification incision. The instrument facilitates safe removal of IOLs.

Several sterilization methods can be used for microsurgical instruments, although steam remains the most widely used method.

The Donnenfeld Limbal Relaxing Incision (LRI) kit (Accutome) contains a set of tools to simplify LRI surgery, including the Donnenfeld LRI Diamond Knife that enables patient treatment at the slit-lamp.

A proprietary titanium caliper (Steiner Titanium Caliper, Stronger Medical Instruments) was designed to maintain accurate measurements and resist deforming of the tips even after numerous cycles of cleaning.

A line of single-use, silicon surgical knives (BD Atomic Edge Safety Knives, BD Medical-Ophthalmic Systems) offers benefits for patients, ophthalmologists, and health-care workers.

Proper decontamination of microsurgical ophthalmic instruments takes time and effort and is not a place for shortcuts.

In the age of toxic anterior segment syndrome, proper care of ophthalmic surgical instruments is of even greater importance to patient safety.

Most of the Association for Research in Vision and Ophthalmology's advocacy efforts in the United States take the form of educating members of Congress about the work its members do to help prevent and cure vision disorders and blindness.

A cluster of cases of postoperative endophthalmitis at the Prince Charles Eye Unit, King Edward Hospital, Windsor, England, over a 4-month period led to a thorough investigation of etiologic factors and multiple changes in the perioperative routines.

Exchanging an IOL is the only choice when the optical clarity of the implant is compromised by internal calcification or glistenings.

There is an inherent tension between the appeal of maintaining a successful, secure business and the desire to expand the business. According to Dr. McDonnell it is much more common for practices and departments to wait too long before beginning the process of adding excellent people to build upon a successful and vibrant operation.

In today's podcast, Nick Mamalis, MD, talks about preoperative and postoperative endophthalmitis prevention. Also, Okihiro Nishi, MD, discusses the Ridley Medal Lecture he delivered about a new IOL refilling procedure to restore accommodation. Additionally, Walter Sekundo, MD, talks about femtosecond lenticule extraction, and Luis Antonio Ruiz, MD, relays outcomes of a recent study regarding intrastromal correction of presbyopia.

Alcon, Inc has launched the +3.0 Add Power AcrySof ReSTOR aspheric intraocular lens (IOL) with blue light filter. The lens completed CE mark approval in the third quarter of 2007 and will be available throughout the EU beginning next week.

In a conversation with Ophthalmology Times Europe, newly-appointed CEO Ari Tiukkanen outlined the reasons behind the recent name change, and discussed how the new name fits into the company's plans for the future.

Bimanual microincision cataract surgery (MICS) and microaxial phacolemulsification provide optically better incisions but bimanual MICS respects more corneal prolateness than microaxial phaco, Mr Jorge Alio, told delegates. "MICS is associated with less corneal oedema in the short term and less inducation of corneal aberrations in the long term," he said.

Ophthalmology is perhaps two steps closer to a possible clinical application of lens refilling with silicon gel for restoring ocular accommodation thanks to a refined procedure developed by Dr Okihiro Nishi, MD of the Nishi Eye Hospital, Japan.

In a worldwide first, Dr Luis Ruiz presented the preliminary clinical results of an ongoing pilot study concentrating on the non-invasive intrastromal correction of presbyopia.
