RETINAL DETACHMENT SURGERY

AND THE USE OF SILICONE IMPLANTS

 

The retina is a thin layer of tissue at the back of the eye. The function of the retina is to change the light energy gathered by the eye into electrical impulses which are carried to

the brain to produce vision. Breaks sometimes occur in the regional tissue causing a loss

of vision. These breaks can be caused by various things including the aging process, heredity, and trauma, such  as a blow to the head. Treatment for this condition often calls 

for retinal reattachment surgery.  

 

During surgery, the break is located by the surgeon. Next, Cryotherapy (freezing of the site) is applied, causing   scar tissue to form and prevent further tearing. The surgeon may need to drain some fluid from the layers of the eye, to allow the retina to settle back into place. Next, a Silicone Band is partly or completely wrapped around the eye to indent the tissue inward. The Band is held with nylon sutures, and is almost always left in place permanently. Often , the surgeon uses another silicon shape (e.g. a Grooved Strip, a Silicone Tire, or other Silicone implants) in combination with the Circling Band. The accessory implant is placed under the Circling Band to give greater indentation at a particular point. The Silicone Band is usually not felt by the patient. The use of a Grooved Strip under a Silicone Circling Band is illustrated below.

Solid Silicone Implants

Circling Bands: A choice of three Circling Bands. All are designed to hold the accessory implant in place and to maintain proper pressure to form a permanent buckle without sclera erosion.
Silicone Lace: The Silicone Lace makes Circling Band placement quicker and easier. The leader (which is removed at the end of the procedure) serves as a solid location to grasp the Band, and makes it easier to pass through a Silicone Sleeve.
Silicone Strips: Silicone Strips can be used alone as permanent implants or when trap door procedures are preformed.
Grooved Strips: Grooved Strips are designed to be used under Circling Bands, Several designs are offered to fit the need for narrow or wide sclera beds, as well as high sclera buckling.
Tires: Tire-shaped implants are designed for use under Circling Bands for wide sclera beds, for breaks near the ora serrata, for multiple breaks, and for high sclera buckles.
Meridional Implants: Meridional Implants give additional buckling in the meridional direction and are used under grooved implants.
Sleeves: Sleeves are used to secure Circling Bands and Silicone Strips in place. 
Tantalum Clips: Clips are used to secure Circling Band.
Wedges: Wedges are used to provide a greater radial buckling effect.
Boats: Boats are utilized under the Tantalum Clips to prevent erosion.
Pad: The Pad is used to close sclera ruptures.
Button: The Button is used under Grooved Strips to produce a higher buckle.
