D Gatinel.Qu' is a clear lens? Ophthalmological realities, March 2012

Clear lens or cataract? Cataract diagnosis is based on the combination of Visual symptoms and signs of the biomicroscope (slit lamp) examinations. The variability of the Visual signs of cataracts (loss of Visual acuity, but also glare, difficulties against day), as well as the anatomical continuum that connects clear lens and advanced cataract are [...]

Refractive multifocal implant

Justification of the OPD for the study of multifocal implants. The OPD allows the study of the optical quality of the eye in detail, which is a definite advantage for the operated eyes of cataract with multifocal implant. In particular, the study of multifocal implants of refractive type is particularly advantageous. The principle of these implants is based on [...]

Cataract and laser femtosecond VICTUS™ platform

VICTUS platform: description the VICTUS platform was originally developed by the company Technolas Perfect Vision (Munich, Germany), and is currently jointly proposed for cataract surgery by the firm of Bausch & Lomb. It is one of the 4 main platforms currently proposed for the realization of the [...] assisted cataract surgery

Index myopia

The myopia of the index is defined as a myopia caused (or accentuated if the eye was previously reached Axile myopia) by an increase in the power of the Crystalline lens. It is mainly encountered during the evolution of a nuclear cataract (clouding of the nucleus of the Crystalline lens). This myopia is linked to an increase in the optical power of [...]

Femtosecond laser cataract surgery

Femtosecond and cataract: justification the femtosecond laser can cut the eye tissue. It is commonly used in refractive surgery (ex: laser Wavelight FS 200), where it can create covers of LASIK. Its use for cataract surgery is still confidential, and even if some platforms are available for purchase [...]

Toric implant

Toric implant: A toric implant definition allows to correct astigmatism after cataract surgery. More than 40% of the operated eyes of cataract present a regular corneal astigmatism greater than 1 diopter. To improve Visual acuity by the eye surgery without glasses, it makes sense to consider the correction of astigmatism of the cornea by [...]

Multifocal implant

Multifocal implant: definition a multifocal implant is an implant to several homes, to correct more than a distance of vision after cataract surgery (ex: distance vision, vision for bifocal implants, and intermediate vision plus with trifocals implants which tend to become the benchmark for multifocalite). The [...]

Monofocal implant

Intra ocular implant cataract surgery during the cataract surgery, remove the lens that is clouded and causes Visual discomfort. Monofocal implant (monofocal implant) are intended to compensate for the strong farsightedness which would be induced if you did not compensate the reduction of optical power ' vergence) related [...]

OPD: Beginner cataract

A patient has a sense of decreased vision of one eye (right eye), while his acuity is 10/10 without correction and 12/10 with a very slight correction of nearsighted astigmatism: Plan (-0.25 x 0 °). The patient reports some symptoms consistent with those of a beginner cataract (glare, difficulty on day). A review at [...]

What is the OQAS instrument?

OQAS (Optical Quality Analyzing System, designed by the Spanish company Visiometrics) is an instrument that provides the direct measure of the combined effect of optical aberrations of high degree and the loss of transparency of the eye circles on the optical quality of the eye. It is of major interest in cataract surgery, but [...]
