The upper parts of the kidneys are partially protected by the eleventh and twelfth ribs, and each whole kidney is surrounded by two layers of fat (the perirenal fat and the pararenal fat) which help to cushion it.
Blood pressure provides the force for blood plasma to be filtered through the thin, porous epithelium of the glomerulus and the neighbouring Bowmans capsule wall to produce the glomerular filtrate, which enter the kidney tubule.
The segment that drains glomerular filtrate from the Bowmans capsule is the proximal convoluted tubule.

The Bowman's membrane is affected by laser eye surgery though the impact of these effects upon vision is not well understood.
In LASIK, the Bowman's remains intact, but often (especially in patients with high prescriptions) develops tiny wrinkles called Bowman's cracks or crinkles.
In PRK (standard and transepithelial versions), the Bowman's is permanently removed in the process of exposing the stroma.

However, it appears to be stratified (having multiple layers of cells, with only the basal cells resting on the basement membrane), because not all cells reach all the way from the basement membrane to the other side of the epithelium, and the nuclei appear at different levels.

 Color Contact Lens Toric
Gross anatomy The stroma or substantia propria, sandwiched between the epithelium and Bowmans layer anteriorly and the corneal endothelium and its supporting Descemets membrane posteriorly, is about 500 ?m thick and constitutes up to 90% of the total corneal thickness [1].
A ground substance or extracellular matrix and a small population of cells consisting primarily of specialised corneal fibroblasts called keratocytes are scattered between regularly arranged lamellae of collagen bundles (primarily type I collagen).
Whilst only 17% of the entire (anterior and posterior combined) lamellae are preferentially aligned in the corneal centre, this appears to increase as one moves to the periphery [9] until the very peripheral stroma, where lamellae take a circular course [3], [6] and [9].

 History   (Site not responding. Last check: 2007-09-07)
Since that time, there have been many variations in technique, but they all have involved lifting up or off a layer (cap) of the cornea, removing some amount of corneal stromal tissue from either the bed or the cap, and then replacing the cap with or without sutures.
In ALK, a surgical instrument called a microkeratome is used to separate a layer of the cornea creating a "cap" or "flap" of corneal tissue.
The essential steps involved in PRK are a gentle wiping or scraping away of the surface layer of epithelial cells, then ablating the corneal tissue with an excimer to change its shape.

For example, an electrolyzed layer or protein film may form on the surface of the electrodes.
The cycle of dehydration and outward current flow continues until the resistance from the tip to the outer rim of the corneal surface, and the full thermal profile, is significantly high to prevent further current flow of a magnitude to further cause denaturing of the corneal tissue.
This prevents the surgeon from denaturing the eye down to the decemets membrane and endothelium layer of the cornea.

Damage to Bowman's layer - The sculpting burns away Bowman's Membrane, the 2nd layer of the cornea.
This layer is the one implicated in keratoconus, a genetic disease whereby the cornea becomes irregular.
Another observation which suggests that destruction of Bowmans layer as a result of PRK may not have negative implications in the long term, is the fact that destruction of this layer as a result of trauma to the cornea apparently does not result in Keratoconus or other disorders.

LASIK is a method of improving the curvature of the cornea by reshaping the inner layers of corneal tissue with the Excimer laser, rather than by recontouring the corneal surface, as with PRK.
First a thin layer of the cornea, the corneal cap is lifted as an instrument called a microkeratome glides across the cornea.
PRK surgery is also considered to have a minimal effect on corneal rigidity, though the loss of Bowmans layer is thought to potentially reduce the cornea's resistance to penetrating injury.

This finding was verified in sections from the grafts where the Bowmans layer was this or was missing.
Experience from a limited histopathology material and confocal microscopy examination both show that a major event is the degeneration of Bowmans layer.
