The Zhongshan Angle Closure Prevention trial 2 was a prospec- tive randomized clinical trial and found that among 889 people aged 50–70 with bilateral PAC suspected who received prophylactic LPI in one eye and observation in the fellow eye, the overall beneficial effect of prophylactic LPI was limited given the extremely rare develop- ment of AACG in both groups after 6 years of follow-up. "Although extended follow-up is warranted, the authors suggest that widespread laser peripheral iridotomy in eyes with narrow angles in patients who are primary angle closure suspects might not necessarily be warranted unless they are diabetic and require frequent pupillary dilation or they have glaucomatous optic neuropathy," Dr. Greenfield said. "An- other caveat is that this study was performed in Guangzhou, China and may not be applicable to other populations." developed progressive shallowing of the ante- rior chamber and myopic shift, and ultimately required pars plana vitrectomy with lensectomy and placement of a posterior chamber IOL. This restored normal anterior segment anatomy, and the patient ended up with 20/15 best cor- rected visual acuity and an IOP of 11 mm Hg. "One should consider this entity in eyes that develop progressive anterior shallowing with progressive myopia, as our patient did," he said. "IOP elevation may not always occur, particularly in eyes with early onset malignant glaucoma." It is important to note that practi- tioners should avoid performing an iridotomy in the fellow eye due to the high risk of devel- oping bilateral malignant glaucoma. New evidence suggests that the benefit of performing prophylactic LPI in primary angle closure suspects may be limited.

Dr. Waltz focused his talk on Zepto (Mynosys) because it is the only device FDA-approved in the U.S., but there are other automated capsulotomy devices. Studies have shown a Zep- to-created capsulotomy has a stronger, more tear-resistant edge when compared to femtosecond laser-created and manual capsulo- tomies. Zepto has also been asso- ciated with a reduced PCO rate, which Dr. Waltz said was "totally continued on page 4 continued on page 3 Dr. Holland presents Dr. Donnenfeld (left) with the Steinert Refractive Lecture award. unexpected" and could be due to "markedly reduced fibrosis inside the capsule." Five-year data, Dr. Waltz said, suggests that with less intracapsular fibrosis you could have less phimosis long-term. With these, Dr. Waltz said there "might be some hidden ben- efits to automated capsulotomies." Nuclear disassembly with miLOOP (Carl Zeiss Meditec) can have refractive benefits, said Sean Ianchulev, MD, New York. Dr. Ianchulev described research that suggests the cen- tripetal fragmentation that avoids stretching the capsular bag (unlike traditional centrifugal phaco-chop techniques) impacts effective lens position. This benefit is in addi- tion to the reduced phaco energy delivered to the eye for nuclear disassembly. In terms of innovation of premium lenses, Robert Maloney, MD, Los Angeles, highlighted the Light Adjustable Lens (RxSight).

Tear stability is maintained by the lacrimal functional unit. Tear instability is a common feature of all types of tear dysfunction and a defining feature of dry eye, he said. It causes inflammation, increases blinking, degrades visual function, and stimulates corneal nociceptors. He said that there are increasing therapeutic options with different mechanisms of action to improve tear stability.

After being asked to give the Binkhorst Lecture, he went to the topogra- phy area in his clinic and noticed bottles of artificial tears. "I real- ized what our technicians figured out a long time ago—that a stable tear film is a big deal," he said. A stable tear film protects and smooths the corneal surface, maintains comfort and quality vision during interblink intervals, and is a key determinant of a suc- cessful outcome in vision correc- tion surgeries. "Tear instability is a sine qua non for tear dysfunction," he said. Tear instability is also a cri- terion in recent consensus dry eye definitions. Fluorescein tear breakup time remains the most common clinical test and gold standard for detection of tear instability. There is increased interest in non-inva- sive breakup methods, Dr. Pflug- felder said, because they provide a digital record, and fluoresce- in can affect tear stability.

John Medina, PhD, gave to at- tendees at the ASCRS Lecture on Science, Medicine and Technology. Dr. Medina is a developmental molecular biologist, researcher, and professor at the University of Washington School of Medicine in Seattle. He is also a New York Times bestselling author and considered to be one of the most engaging and crowd-pleasing speakers in the world of neuroscience. In this inspiring and exciting lecture, Dr. Medina described to attendees several principles of cognitive neuroscience that can help physicians grab and keep the attention of an audience, whether they are lecturing to a room full of people or having a one-on-one chat with a patient. Keeping the audience's attention will make the information stick and ensure the audience remembers it later, Dr. Medina said. Dr. Medina explained how human brains pay attention to different stimuli and presented a roadmap of how physicians can apply these principles to everyday communication situations, like giv- ing a lecture to a group of medical students or having a private chat with a patient.

The Beacon Aqueous Microshunt (MicroOptix)—the brain child of David Brown, MD, 20 years in development—is 3.1 mm in length with an external flange width of 7 mm. It is implanted into a paracentesis-like incision, allowing aqueous to flow through a central channel. Mitigation against retrograde flow of pathogens would be a concern for such an idea. How- ever, Dr. Riedel said that this is prevented 1) by shear stress and 2) by the polyethylene glycol material that composes the central layer of the three-layer device. Polyeth- ylene glycol is considered the gold standard of anti-biofouling materi- als. It is super hydrophilic, and it prevents adherence of protein and bacteria to the channel wall, Dr. Riedel explained. In a porcine animal model followed to 6 months, Dr. Riedel noted no infections and signifi- cant, persistent IOP lowering. An aggressive bacterial challenge with the device on eight animals did not result in endophthalmitis, Dr. Riedel continued. Preliminary data from an early bird study in the U.S. and E.U. has shown a mean IOP of 13 mm Hg at 6 months, compared to a base- line mean of 27 mm Hg that was medicated with no washout of patients. Eighty-seven percent of Dr. Kurtz takes attendees through the collaborative innovation process. continued from page 64
