The transparent front part of the eye that covers the iris, pupil, and anterior chamber, providing most of an eye’s optical power. The cornea has unmyelinated nerve endings sensitive to touch, temperature and chemicals; a touch of the cornea causes an involuntary reflex to close the eyelid. Because transparency is of prime importance the cornea does not have blood vessels; it receives nutrients via diffusion from the tear fluid at the outside and the aqueous humour at the inside and also from neurotrophins supplied by nerve fibers that innervate it. The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.

DSEK Procedure

Dr. Lee Webster is performing the latest, advanced procedure in cornea transplantation. This cutting-edge procedure is named Descemets Stripping Endothelial Keratoplasty, or DSEK for short. DSEK has replaced the traditional full thickness cornea transplant, known as Penetrating Keratoplasty, in a number of patients. A countless number of these patients have a cornea disease involving only the most inner layer of the cornea, the DSEK procedure replaces just the abnormal layer, leaving the remainder of the healthy cornea untouched; where the traditional procedure replaced the whole cornea in its entirety. The advantages of DSEK are numerous and significant. One, the procedure is safer, well tolerated, and performed under local anesthesia. Two, the healing time is much faster, as DSEK patients often regain vision in a mere few weeks compared to many months or even a year with the traditional procedure. And last, the DSEK procedure has only a slight effect on the patient’s glasses prescription while the traditional procedure may cause dramatic changes and the induction of tremendous astigmatism.

What is pirate slang?

The most common usage is Australian slang for a man searching around for casual sex, as in "on the pirate" or the verb "to pirate". It has also been used to describe a pimp who steals a prostitute from another pimp. A more recent slang usage is a fictitious sex act called "the pirate" or "the angry pirate".

en.wikipedia.org - Pirate (sexual slang) - Wikipedia

Pirate has multiple meanings in sexual slang. Several of them emerged in the 20th century and play off the tradition that pirates took whatever they wanted, including sex, which was "seen as a conquest."[1]

Usage [ edit ]

The most common usage is Australian slang for a man searching around for casual sex, as in "on the pirate" or the verb "to pirate".[2] It has also been used to describe a pimp who steals a prostitute from another pimp.[2] A more recent slang usage is a fictitious sex act called "the pirate" or "the angry pirate".[3] Sex columnist Dan Savage fielded a question from a reader who asked about the act. The reader described it as "when you’re getting a blowjob from a girl, and when you cum, you ejaculate in her eye. Then you kick her in the shin. The result is the woman is squinting her eye and hopping up and down on one foot, holding her leg and screaming, "ARRRGH!"[4] Savage replied "no one has ever attempted "the Pirate," just as no one has ever performed a Hot Karl, delivered a donkey punch, or inserted an Icy Mike. They're all fictions."[4]

Compound words [ edit ]

The term is also used in compound words, including "tango pirate," popularized in the early 20th century to describe gigolos who sought out wealthy women at dances.[2] The terms "butt pirate" or "ass pirate" or "poo pirate" have been used as sexual slurs for gay men.[1] The term "Pamper pirate" has been used to describe a child molester.[2]
