INTACS In India
About INTACS?
The INTACS (Intrastromal Corneal Ring Segments or Intracorneal rings) are small rings of biocompatible material, which are placed in the cornea of the patients with keratoconus in order to improve the topographic images and the visual acuity of the patients. The placement of the rings demands the creation of a tunnel in the cornea with the use of a 5th generation Laser the iFS Advanced Femtosecond Laser and the patient does not feel them in his eye at all. The placement of Intacs is decided by the surgeon depending on the particular characteristics of each patient. The intervention is conducted under anesthaetic drops and is painless.a
The retina is a thin layer of light sensitive tissue on the back wall of the eye. The optical system of the eye focuses light on the retina much like light is focused on the film or sensor in a camera. The retina translates that focused image into neural impulses and sends them to the brain via the optic nerve. Occasionally, posterior vitreous detachment, injury or trauma to the eye or head may cause a small tear in the retina. The tear allows vitreous fluid to seep through it under the retina, and peel it away like a bubble in wallpaper.
Signs and symptoms
fashes of light (photopsia) – very brief in the extreme peripheral (outside of center) part of vision.
a sudden dramatic increase in the number of floaters.
a ring of floaters or hairs just to the temporal (skull) side of the central vision.
Risk factors
Risk factors for retinal detachment include severe myopia, retinal tears, trauma, family history, as well as complications from cataract surgery.
Epidemiology
Retinal detachment is more common in people with severe myopia (above 5–6 diopters), in whom the retina is more thinly stretched. In such patients, lifetime risk rises to 1 in 20.About two-thirds of cases of retinal detachment occur in myopics.Myopic retinal detachment patients tend to be younger than non-myopic ones.
INTACS
Intrastromal corneal rings (or intracorneal rings) are small devices implanted in the eye to correct vision. A typical vision correction using corneal rings would involve an ophthalmologist making a small incision in the cornea of the eye, and inserting two crescent or semi-circular shaped ring segments between the layers of the corneal stroma, one on each side of the pupil. The embedding of the rings in the cornea has the effect of flattening the cornea and changing the refraction of light passing through the cornea on its way into the eye.
A scleral lens is a large contact lens that rests on the sclera and creates a liquid-filled vault over the cornea. In dry eye sufferers this lens bathes the cornea, reducing blurred vision caused by dry eye and providing relief from the dry eye pain caused by the sensitive nerves in that area.
