The purpose of this study was to design and calibrate a device to measure the dynamics of thermal shrinkage in corneal and scleral strips. The apparatus consists of a thermoelectric cell controlled by a temperature controller designed to generate tem

A simulator for phacoemulsification cataract extraction is developed. A three-dimensional visual interface and foot pedals for phacoemulsification power, x-y positioning, zoom and focus were established. An algorithm that allows real time visual feed

It is concluded that there is no angular dependence of back scattering of light from a nuclear cataract. This implicates that reading one meridian, e.g. the 90 degree, is enough for measurement of nuclear cataract with slit lamp microscopy with Schei

It is concluded that sunglasses shall block UVR and toxic blue light, allow transmittance of signal light and bring luminous intensity behind the filters to a comfortable level. It was found that some commercially available sunglasses, apart from one

The penetration of 300 nm ultraviolet radiation (UVR) in the anterior cortex of the crystalline lens was 0.45 mm, penetration being expressed as the distance attenuating the transmittance to 1/e 2 . The estimation is based on measurement of in vivo i

Scheimpflug slitlamp microscopy is the outstanding method to record nuclear light scattering from the crystalline lens. Until yet, calibration of measurements with this device has not been possible. In the current work, an external standard for Schei

Thermokeratoplasty is a procedure utilizing heat to reshape the surface of the cornea through shrinkage of collagen within the stroma. We have constructed an apparatus for measurements of thermally induced corneal shrinkage. Using this apparatus, we

The smoothness and accuracy of PMMA ablations with a prototype scanning photorefractive keratectomy (SPRK) system were evaluated by optical profilometry. A prototype frequency- quintupled Nd:YAG laser (Laser Harmonic, LaserSight, Orlando, FL) was use

A scanning beam of nano-second pulses at 213 nm flattens the cornea as predicted. However, there is a considerable variability in the flattening and the ablation is not safe. Ablation for 16 D flattening with an active spot overlap of 50% induced 8.9
