A new non-apodized diffractive trifocal IOL allows 88% energy utilization and sends energy to near (40 cm), a preferred intermediate distance (60 cm), and far (infinity). Early results for visual acuity, contrast sensitivity, and photopic symptoms are encouraging.

Multifocal IOLs with a trifocal diffractive optic design are available outside of the United States. They provide good visual acuity for distance, intermediate, and near and appear to provide slightly better intermediate vision than bifocal diffractive multifocal IOLs.
Findings from an international trial with follow-up in some subjects now extending beyond 6 years show that a retinal prosthesis (Argus II Retinal Prosthesis System, Second Sight Medical Products) remains safe, said Allen C. Ho, MD.
New diagnostic platforms for dry eye disease can help in determining the underlying cause and severity, which is useful for guiding treatment decisions.
Since dry eye is an early presenting sign, eye-care providers need to maintain a high index of suspicion for Sjögren’s syndrome in patients with clinically significant dry eye.
Maintenance is an important determinant for the efficacy of any intervention
Achieving alignment of strabismus can be difficult in children with syndromic craniosynostosis as the causes are multifactorial.
Children are particularly sensitive to systemic side effects of topical glaucoma medications for a variety of reasons. Increased caution is necessary when using these agents.
A study provides new insight on the risk of early ocular surface-related complications among patients undergoing CXL for keratoconus.
The cornea maintains a better prolate shape after myopic PRK using a wavefront-optimized versus a wavefront-guided ablation profile.
