Measuring Daily Disposable Contact Lenses against Non-wearer Benchmarks

Percy Lazon de la Jara, Jennie Diec, Thomas Naduvilath, and Eric B. Papas
 
In this study, the authors compare the experiences of contact lens wearers to spectacle and non-contact lens wearers and show that some daily disposable contact lenses can provide comfort and vision that is indistinguishable from patients who use no correction at all.

Visual Performance of Daily-Disposable Multifocal Soft Contact Lenses: A Randomized, Double-Blind Clinical Trial
 
Jennifer Sha, Daniel Tilia, Danny Kho, Hamdy Amrizal, Jennie Diec, Nisha Yeotikar, Monica Jong, Varghese Thomas, and Ravi C. Bakaraju
 
This study highlights the differences between several modern daily-disposable multifocal soft contact lenses to assist eye care practitioners in fitting presbyopic contact lens wearers.

Impact of Dry Eye on Prolonged Reading 

Sezen Karakus, Priya Mathews, Devika Agrawal, Claudia Henrich, Pradeep Y. Ramulu, and Esen K Akpek
 
The results from this study show how dry eyes can affect reading speed. Practitioners may find the correlation between reading speed and corneal staining OSDI scores clinically useful.

Ophthalmic Conditions Associated with Inpatient Falls among Veterans

Giovanni Campagna, Paul Chamberlain, Silvia Orengo-Nania, Kristin Biggerstaff, and Sumitra Khandelwal
 
Prevention of inpatient falls could be improved by measuring visual function and by being aware of any ocular health concerns.

Scotoma Simulation in Healthy Subjects 

Sascha Klee, Dietmar Link, Stefan Sinzinger, and Jens Haueisen
 
Our authors demonstrate that it is possible to simulate an absolute scotoma similar to age-related macular degeneration, using occlusive contact lenses along with a miniaturized full-field adaptation device. 

Comparison of the Ultraviolet Light Filtering across Different Intraocular Lenses
 
Mari Carmen García-Domene, Cari Pérez-Vives, Cristina Peris-Martínez, and José María Artigas
 
Some intraocular lenses are better at blocking ultraviolet light than others. This study compares ultraviolet light filtering across different intraocular lenses. 

Accuracy of a Smartphone Based Autorefractor Compared to Gold-Standard Refraction 
 
V. Swetha Jeganathan, Nita Valikodath, Leslie M. Niziol, Sean Hansen, Hannah Apostolou, and Maria A. Woodward
 
This study compares the portable smart-phone based autorefractor, Netra, to clinical subjective refraction. While Netra refractions are different, they may be useful in low resource settings.

Repeatability of Anterior Curvature Metrics in Normal and Keratoconic Eyes with a Portable Hand-held Topographer
 
Fernando José Fernández-Velázquez

Results from this study show that a portable hand-held topographer can provide highly repeatable measurements in both normal and keratoconic eyes.

Ranibizumab versus Dexamethasone Implant in Macular Edema Secondary to Branch Retinal Vein Occlusion: Two-year Outcomes

Abdullah Ozkaya, Hatice Nur Tarakcioglu, and Ipek Tanir
 
Two years after branch retinal vein occlusion, the Ranibizumab ocular implant was superior to Dexamethasone implants, improving both visual and anatomical outcomes.

Identification of a CNGB1 Frameshift Mutation in a Han Chinese Family with Retinitis Pigmentosa 
 
Qin Xiang, Yi Guo, Yanna Cao, Wei Xiong, Xiong Deng, Hongbo Xu, Yu Li, Hao Deng, and DongDong Du
 
The authors have identified a CNGB1 frameshift mutation in retinitis pigmentosa. Practitioners may use this information for future genetic counseling.
