Lens aplasia: a new mutation producing lens abnormality in the mouse.
Само регистрирани потребители могат да превеждат статии
Вход / Регистрация
One female with bilaterally closed eyelids was observed in a breeding colony of BALB/c mice in our laboratories. This eye abnormality was considered to be heritable because offspring with the same abnormality were produced from the mating of this female with a normal male littermate. From the

OBJECTIVE
To discuss the surgical techniques and therapeutic effects of phacofragmentation of the dislocated lens in the vitreous cavity.
METHODS
Phacofragmentation was performed on 23 eyes of 23 patients with dislocated lens or subluxated lens in the vitreous cavity. With high suction and moderate

We showed that a Ag-SiO(2)-Ag Fabry-Pérot cavity can be used in near-field imaging based on omnidirectional resonance tunneling. The omnidirectional resonance was experimentally demonstrated in the Ag-SiO(2)-Ag resonant cavity working at a wavelength of 365 nm. The resonant cavity lens with high

A method for solving exactly the Helmholtz equation in parabolic rotational coordinates is presented using separability of the eigenfunctions and the Frobenius power series expansion technique. Two examples of interest in acoustics are considered and analyzed quasianalytically: The acoustic pressure
A new biconcave contact lens for vitrectomy in eyes with intraocular lens implantation.

Вход / Регистрация
The authors report a new biconcave contact lens capable of providing superior surgical views of eyes during vitrectomy and intraocular lens implantation under both fluid-filled and air-filled conditions. The new biconcave lens is made of a glass with a high refractive index (nd = 1.883). The lens is
Apoptosis in the lens anlage of the heritable lens aplastic mouse (lap mouse).

Adult homozygous lap mice show various eye abnormalities, such as aphakia, retinal disorganization, and dysplasia of the cornea and anterior chamber. In the fetal eye of a homozygous lap mouse, the lens placode seems to develop normally. However, the lens vesicle progresses abnormally to form a mass
Removal of lens fragments from the vitreous cavity.

Between March 1993 and September 1994 we treated 25 cases of lenses in the vitreous cavity. Nineteen of the 25 were the result of dislocation during phacoemulsification. During this time, we adopted a single surgical algorithm involving vitrectomy, heavy liquids and ultrasound fragmentation. The
Management of dislocated lens material.

Posterior dislocation of lens fragments is a well-known complication of phacoemulsification. Retained lens material in the vitreous cavity can lead to poor visual acuity related to inflammation, corneal edema, and glaucoma. Pars plana vitrectomy is frequently necessary to remove the dislocated lens

Among 106 patients of traumatic lens dislocation, comprising 70 males and 36 females aged 3-90 years, secondary glaucoma occurred in 93 cases (87.7%). The authors are of the opinion that lenses dislocated into the anterior chamber should be removed as soon as possible, and dislocated lens in the
Convex lens-induced nanoscale templating.

We demonstrate a new platform, convex lens-induced nanoscale templating (CLINT), for dynamic manipulation and trapping of single DNA molecules. In the CLINT technique, the curved surface of a convex lens is used to deform a flexible coverslip above a substrate containing embedded nanotopography,

Вход / Регистрация
OBJECTIVE
To demonstrate a rare complication in contactology.
METHODS
A 26-year-old female had "lost" her hard contact lens in the right eye 2 years previously. Afterwards, new contact lenses were not tolerated. The patient had a slight intermittent epiphora but no further complaints. She consulted
[Intraocular lens explantation and retroiridal iris claw lens implantation via the pars plana : Video article]
Само регистрирани потребители могат да превеждат статии
Вход / Регистрация
Objective of surgery: The aim is the explantation of an intraocular lens (IOL) due to dislocation into the vitreous cavity with subsequent secondary implantation of a retropupillary iris claw IOL via the pars plana without creating a
Sectioning a luxated intraocular lens inside the vitreous cavity.

Вход / Регистрация
We describe a new technique for sectioning an intraocular lens (IOL) inside the vitreous cavity. The IOL had a broken haptic and was accidentally luxated after a complicated cataract surgery with posterior capsule rupture. The primary indication to cut the IOL in half inside the vitreous cavity is
Human cataractous lens nucleus implanted in a sheep eye lens as a model for phacoemulsification training.

Вход / Регистрация
We describe a realistic and inexpensive experimental cataract model for phacoemulsification training. After a capsulorhexis is performed, a deep cavity in the lens of an enucleated sheep eye is formed by phacoemulsification through a lateral incision. An undamaged human cataractous lens nucleus
