PURPOSE To compare the outcomes of 2 techniques (Anwar vs. Melles) of deep anterior lamellar keratoplasty (DALK) in patients with keratoconus. DESIGN Randomized, double-blind clinical trial. PARTICIPANTS Fifty-seven eyes of 57 patients 20 to 35 years of age were enrolled. METHODS Patients with clinical diagnosis of keratoconus who were contact lens intolerant and whose corrected distance ...

This paper provides an overview of a Design-Based Research (DBR) study which resulted in a prototype of the MobileEnabled Language Learning Eco-System (MELLES) and replicable design principles to guide development of practical innovative mobile learning interventions. The MELLES solution was generated to augment in-class practice of ESP skills with learning embedded in real-life dynamic communi...

A 488 nm argon laser (Melles Griot) was used as the excitation source and the laser beam was focused using a 100X, 1.3 N.A., oil immersion apochromatic objective (Olympus). Throughout experiments excitation laser power was kept at 150 μW using neutral density filters. The emitted fluorescence was then collected by the same objective and an initial dichroic mirror (505DCXE, Chroma Technology) se...

The cornea remains in a state of deturgescence, maintained by endothelial cell Na+/K+ ATPase and by tight junctions between endothelial cells that limit entrance of fluid into the stroma. Fuchs' endothelial corneal dystrophy (FECD) was initially described by Fuchs in 1910 as a combination of epithelial and stromal edema in older patients. It manifests as bilateral, albeit asymmetric, central co...

We have developed a portable, motorized, multi-shot, third-order autocorrelator capable of measuring the time width of a large bandwidth pulse with femtosecond acuracy. Here we give a detailed description of the device and report measurements made in the Pegasus laboratory on a Coherent Legend Elite laser system, generating a short pulse, (IR) λ = 800nm E < 3mJ , and a frequency tripled pulse, ...
