Identifying, managing dysphotopsia after cataract surgery
Following cataract surgery, patients can present with a variety of visual complaints—i.e., dysphotopsias, aberrant optical phenomena that interfere with vision after IOL implantation. Positive dysphotopsias include rainbows, streaks, crescents, rings, halos, and veiling glare, haze, and fog. Negative dysphotopsias are relative and absolute scotomas, said Jack T. Holladay, MD, from Baylor College of Medicine, Houston.
Study finds QPI-1007 safe for patients in range of doses
One intravitreal injection of QPI-1007 (Quark Pharmaceuticals) to treat nonarteritic anterior ischemic optic neuropathy (NAION) was safe with no serious adverse events in a phase I trial, and most patients gained 3 or more lines of vision, according to Bradley Katz, MD, PhD, who reported the results on behalf of the Quark Study Group.
Study: Combined SMILE, CXL safe for keratoconus
Combined small-incision lenticule extraction (SMILE) and intrastromal collagen crosslinking (CXL) to treat forme fruste keratoconus is safe, efficient, accurate, predictable, and stable for treating keratoconus for at least 1 year, according to Enrique O. Graue Hernandez, MD, MSc.
Tubes or trabeculectomy to prevent glaucoma: That is the question
Shunt implantation and trabeculectomy are important procedures in the battle to prevent blindness from glaucoma, and tubes are steadily gaining in popularity possibly because of the more predictable postoperative course.
Dual-optic lens accommodates vision at all distances
A dual-optic accommodating IOL (Synchrony, Abbott Medical Optics) seems to have met the presbyopic challenge by providing good vision at far and intermediate distances.
Trifocal IOL facilitates intermediate vision
A diffractive trifocal IOL (FineVision, PhysIOL) provides a peak modulation transfer function for intermediate vision.
Finding the culprit in long-standing ptosis and diplopia
In difficult neuro-ophthalmology cases, selecting the correct imaging tools and trusting the skill of the radiologist are highly important.
Strategies for repairing late orbital fractures
Computer-assisted techniques help achieve the best possible results in complicated cases of anatomic reconstruction.
Managing post-occlusion with advanced fluidics
An ophthalmologist compares two currently available fluidics systems and their ability to recover after occlusion is interrupted.
A novel index for diagnosing keratoconus
The Bowman’s ectasia index (BEI) may be a novel index for diagnosing keratoconus with a sensitivity and specificity of 100% for both, according to study results reported by Mohamed F. Abou Shousha, MD, PhD.
