|Femtosecond Lasers in Cataract Surgery|
|An Exciting New Use of Advanced Technology
Modern surgical techniques have completely transformed cataract removal procedures into one of the safest and most predictable of all. Recently, femtosecond lasers that were introduced into refractive surgery techniques like LASIK are being tested by eye surgeons for use in cataract removal.
Femtosecond lasers are extremely short, powerful bursts of light that are used in LASIK procedures. Their use in cataract surgery involves...|
|Flashes, Floaters and Spots|
|Occasionally, as we look at the sky or at a blank wall, we notice small spots that look like grey particles, floating in the visual field; they can be shapes such as loops, lines or cobwebs and they seem to move somewhat with the eyes.
Sometimes we are aware of short flashes of light as well. Both floaters and flashes are usually benign and are more annoying than serious. However, a sudden onset of floaters or flashes of light can be signs of something more serious; we will discuss what...|
|Floaters Flashes and Spots |
In most cases floaters flashes and spots are more irritating than harmful. They appear as shapes such as circles lines or cobwebs that float or flash before your eyes. Floaters are actually shadows cast on the retina by irregularities within the jelly-like substance inside of the eye called the vitreous humor. They can develop during embryonic development or you can acquire them over time.
For most people floaters come with age because the transparent semi-gelatinous vitreous humor th...|
|Fluorescein Angiography |
|Most people do not know that the only place in the human body where blood vessels can be viewed in their natural state, without cutting something open, is in the back of the eye. For this reason, the eye is one of the best places to evaluate diseases and conditions that affect the circulation; what is happening in the ocular blood vessels is also happening elsewhere in the body.
For this reason, Fluorescein Angiography (FA), a test in which the vegetable dye called fluoresc...|

|Fourth Nerve Palsy |
|There are ten cranial nerves, each in charge of a different function, like the sense of smell, the optic nerve, and the one that controls most eye movement. The fourth nerve, the trochlear, is in charge of only one eye muscle, called the superior oblique, which moves each eye downward and inward, with some rotational effect also.
The fourth nerve, also called the trochlear nerve is the longest of the cranial nerves, and the one most sensitive to damage from trauma (head inju...|
|Fuchs Dystrophy |
|A corneal dystrophy is a condition in which one or more types of tissues of the cornea, the clear dome-shaped structure located at the front of the eye, begin to lose their clarity, compromising vision. There are more than 20 corneal dystrophies, which share certain traits, including:
They are usually genetic
They affect both eyes equally
They are not caused by diet, injury or any lifestyle choices
Most are progressive, usually in a gradual way
Most begin in one of the five laye...|
