Finding a fix for irregular astigmatism after PK
Transepithelial topography-guided PRK can help correct irregular astigmatism after penetrating keratoplasty.
Tracking growth of ultra-widefield imaging in disease management
Ultra-widefield imaging has become an important component of a thorough eye exam and is taking on a larger role in retina and comprehensive ophthalmology.
Centroid value, posterior cornea input adds game for toric calculators
Surgeons should use a centroid value for surgically induced astigmatism rather than a mean or median value when working with toric IOL calculators.
Study finds advantages using trifocal IOL to correct presbyopia
A 4-year study following trifocal IOL implantation (AT LISA tri 839MP, Carl Zeiss Meditec) found that the lens provided good distance, near, and intermediate visual acuity. The lens also improved patient quality of vision with better diffraction and less reduction in contrast sensitivity.
Fixed-combination glaucoma agent yields positive safety, efficacy data
A phase III trial for the fixed-combination netarsudil/latanoprost agent (Roclatan, Aerie Pharmaceuticals)reports positive results. The company plans to submit a NDA for the drug in early 2018.
Progression of visual field loss not always easy to test, analyze
Assessing visual field progression in glaucoma may be more of an art than a science—and there is no one test to give reliable information that is needed about a patient, said Chris A. Johnson, PhD, DSc, FAAO, FARVO, professor, Department of Ophthalmology, and director, Visual Field Reading Center, University of Iowa, Iowa City.
PiXL appears promising for low myopia
The use of epi-on photorefractive intrastromal cross linking reduced myopia by about 0.25 D in a small study; In a high-oxygen group, the effect averaged 1.25 D.
Visual acuity, other tasks appear unaffected by inlay decentration
Decentration of less than 0.75 mm from a light-constricted pupil with a novel corneal inlay for the surgical correction of presbyopia does not affect visual acuity, task performance, or severity of halos and glare.
OCT imaging yields better visualization
Future increases in imaging speed will improve performance and functionality for OCT and OCT angiography (OCTA), said James Fujimoto, PhD.
Phaco technology evolves over time
Fifty years after the idea for phacoemulsification came to Charles Kelman, MD, few would have predicted that surgical platforms would evolve to where they are today.
