Intrastromal ring segments improve distance visual acuity up to 10 years
Intrastromal ring segments yielded long-term improvement in distance visual acuity in eyes with keratoconus, according to a study. The retrospective study included 36 eyes that had keratoconus and received Ferrara intrastromal ring segments (AJL Ophtha…
Aerie initiates phase 2b study of glaucoma drug
Aerie Pharmaceuticals has initiated a phase 2b study of a novel drug for the treatment of glaucoma, according to a press release. PG324 is a fixed-combination of Aerie’s AR-13324 and latanoprost, the release said.
Trabeculectomy after vitreoretinal surgery with silicone oil yields low success rate
A majority of patients who underwent trabeculectomy with mitomycin C for glaucoma after vitreoretinal surgery with silicone oil failed to attain IOP less than 21 mm Hg, according to a study. Investigators measured IOP, visual acuity and glaucomatous ne…
Meeting increasing demand for intravitreal injections next goal of ophthalmology in Slovenia
Slovenia, a country with a long tradition of high medical quality, is currently facing the challenge of funding and organizing high volumes of intravitreal procedures to maintain the standards that patients expect.

Postmenopausal hormones containing estrogen may reduce glaucoma risk
Using postmenopausal hormones (PMH) containing estrogen may reduce a woman’s risk for primary open-angle glaucoma (POAG), a common form of the disease related to the build-up of pressure inside the eye, according to a report published by JAMA Ophthalmo…

Study defines causes of astigmatic surprise after toric IOL implantation
Understanding the root causes of refractive cylinder surprises that manifest after toric IOL implantation can enable surgeons to choose appropriate surgical methods for each patient’s individual case, according to a study.The experimental study set out to define these causes by using vergence formulas to bring all lens powers to the corneal plane. The refractive cylinder effect of rotating a toric IOL and demonstrating how prevailing astigmatism and various planning and surgical steps contribute to postoperative refractive cylinder were determined by double-angle vector diagrams.
Lower-concentration NSAID reduces pain, inflammation after cataract surgery
Bromfenac ophthalmic solution 0.07% dosed once daily reduced intraocular inflammation and pain after cataract surgery when compared with placebo, according to a study. In two prospective, double-masked, phase 3 clinical trials, 222 patients randomized …
BLOG: If you only had 17 years, how would you choose to live your life?
A remarkable 17-year-old young man died in New England a few weeks ago. His name was Sam Berns, and he had a rare disorder called progeria, which results from an untreatable genetic mutation that causes aging of all the body’s cells. Sam was diagnosed shortly after birth with this affliction, which occurs in one in 8 million newborns. His parents, both physicians, formed a foundation to conduct research on the condition. Throughout his short life, they also wisely advised Sam to choose activities that would enrich his life most fully.
Research has important implications for potential treatments of congenital cataracts
Deprivation of vision during critical periods of childhood development has long been thought to result in irreversible vision loss.
New brain-scanning technique allows scientists to see when and where the brain processes visual information
Every time you open your eyes, visual information flows into your brain, which interprets what you’re seeing. Now, for the first time, MIT neuroscientists have noninvasively mapped this flow of information in the human brain with unique accuracy, using…

Speaker: Lasers essential in future of refractive cataract surgery
Laser-assisted refractive cataract surgery, although costly, provides better safety, visual outcomes and reproducibility and will be the driving innovative factor in the future, according to a speaker at Hawaiian Eye 2014. “The principal source of error that we face now is the effect of lens position,” James P. McCulley, MD, FACS, FRCOphth, said. “A half millimeter off in lens position will give us a diopter off in our IOL.” The literature supports that the main cause for this variability is the structure of the capsulorhexis, he said.
Separating cataract consult, surgical planning appointments yields best IOL match, speaker says
Successfully pairing IOLs with eyes calls for proper pacing of appointments, knowing and educating patients, and accurately analyzing data during the preoperative and surgical planning stages, a presenter said at Hawaiian Eye 2014. Moving too swiftly through the preoperative stage overwhelms patients and yields inaccurate data, Cynthia Matossian, MD, told colleagues. “Decouple the cataract consult appointment from your surgical testing appointment,” Matossian said. During the cataract consult, the cornea is barraged with anesthetic drops, mydriatic agents, dyes and applanation devices, she said, which makes it difficult to obtain accurate measurements.

Hydrogel corneal inlay improves near, intermediate, distance vision at 3 months
A hydrogel corneal inlay improved near, intermediate and distance vision, regardless of preoperative refractive error, according to a study presented at Hawaiian Eye 2014. Roger F. Steinert, MD, OSN Cornea/External Disease Board Member, spoke about the Raindrop near vision inlay (ReVision Optics). “This is really better than anybody expected,” Steinert said. “It’s providing uninterrupted functional vision and satisfaction across a very wide range of preop refractive errors. … We think the real sweet spot is going to be somewhere around the very low hyperopic side and not higher than +1.5 (Read more...)
