Geographical Decline
In certain instances, geographical atrophy is the sole macular degeneration surgery for the dry form of AMD. It is a complex operation in which the natural lens of the eye is removed and a telescope the size of a pea is implanted behind the retina of the eye. This telescope is designed to magnify the central retinal image of the visual field. The focus is on an unaffected portion of the retina.
This device enables the individual to see close-up images with the afflicted eye’s central vision. However, the telescope can cause adverse effects such as decreased peripheral vision, double vision, corneal edoema, and eye infection.
It is an uncommon and intricate operation. This surgery was approved by the FDA in 2010, and 600 patients have already received the implant.
The implantation of the telescope device is performed as an outpatient procedure, and the patient may be required to abstain from food and liquids prior to surgery.
