Aqueous Fluid/Aqueous Humor:
A clear fluid that fills
the front part of the eye providing oxygen and nourishment.
A refractive error that prevents the
light rays from forming a single focus on the retina.
Inflammation of the margins of the eyelids.
Plastic surgery of the eyelids.
A condition in which the crystalline lens
of the eye, the capsule surrounding the lens, or both,
lose clarity causing loss of visual acuity.
Inflammatory enlargement of the meibomian
gland of the eyelid.
CO 2 Laser:
Carbon dioxide laser used extensively for
laser skin resurfacing and plastic surgery.
A thin mucous membrane that lines the
white part of the eye (sclera) and the inside of the
The clear, transparent portion of the front
of the eye.
Laser used for laser facial peels and
laser skin resurfacing.
Laser used to precisely reshape the
cornea for laser vision correction (LASIK and PRK.)
A condition of the eye causing the image
to focus beyond the retina. In our youth the innate
accommodating (focusing) power of the eyes often compensates
for farsightedness; as we age, our eyes become less
able to make this accommodation.
Laser Vision Correction
piece of glass or plastic used to refract (bend) light
rays to correct the effects of myopia, hyperopia or
elastic crystalline lens of the eye that lies directly
behind the pupil and is held in place by zonules
(fibers that are attached to the ciliary body). This
lens is responsible for fine-tuning visual images.
condition of the eye, usually due to the cornea being
too curved or the eye being too long, whereby the focal
image is formed in front of the retina (also known
The second cranial nerve.
The optic nerve transmits signals from the retina to
for Photo Refractive Keratectomy
A condition of the optical system of
the eye whereby images are not focused clearly on the
retina. Glasses, contact lenses or refractive surgery
can usually correct the condition.
The sum of steps performed
in arriving at a decision as to what lens (if any)
will most benefit the patient. The steps include refractometry,
measurement of visual activity, and exercise of clinical
surgery to change the way the structures of the eye
bend light rays in order to focus the light rays on
the retina. The surgery is usually performed on the
The region at the post-exterior
chamber of the eye that contains all the sensor receptors
for the transmission of light. These receptors consist
of two main types--rods and cones. Cones function best
under daylight conditions. Rods function best in dim
light and allow us to see at night and with good vision.
Incisional surgery of the
cornea to flatten the cornea and correct nearsightedness.
The "white" coating
of the eye. This outer layer maintains the integrity
of the eye.
The inner coating of the sclera that
provides much of the blood supply to the retina.
The jelly-like fluid inside the eyeball
