An ophthalmic lens (Q) has a progressively variable focal power, taken into account of the convergence of the eyes, wherein amount of a horizontal displacement of an umbilical meridian curve (M-M') has a relationship proportional to an additional refracting power (D) at respective positions ...
IOL power calculation after myopic corneal refractive surgery can be calculated with a variety of methods that lead to relatively accurate outcomes, with 60 to 70% of eyes showing a prediction error within 0.50 diopters.Background Calculating the intraocular lens (IOL) power in eyes with prior cor...

crystalline lens, lens of the eye, lens - biconvex transparent body situated behind the iris in the eye; its role (along with the cornea) is to focuses light on the retina arteria centralis retinae, central artery of the retina - a branch of the ophthalmic artery; enters the eyeball with...
(refractive index 1.69) and coated with a film of magnesium fluoride tonullifythe surface reflections. Flint glass, or bariumcrown, which has less dispersive power, is used in fused bifocals. Plastic lenses have become increasingly popular, particularly if the weight of the lenses is a problem,...
Imaging demonstration along with adaptive optics To replicate the excellent optical adaptivity of human eyes, we have built an optical system comprising a fixed lens (artificial cornea), an electronic iris, and an artificial crystalline lens. Both electronic iris and artificial crystalline lens are bas...
To develop a novel machine learning-based intraocular lens (IOL) power calculation formula for highly myopic eyes. A total of 1828 eyes (from 1828 highly myopic patients) undergoing cataract surgery in our hospital were used as the internal dataset, and
Therefore, an artificial eye system was configured to better quantify the refractive power of the thermal lens generated within the human eye. The influence of 1319 nm energy with power levels from 220 to 630 mW and exposure durations between 0.25 and 1.00 s was evaluated based on changes ...
Opening to coincide with the 65th anniversary of the Barbie ‘brand’ in 2024, the exhibition will explore its story ‘through a design lens’, including fashion, architecture, furniture and vehicle design. The show includes more than 250 objects, with dolls dating from 1959 to the present day...
