PEARL ;- New treatment to cure presbyopia

Presbyopia usually occurs beginning at around age 40, when people experience blurred near vision when reading, sewing or working at the computer.

Researchers are exploring ways to treat presbyopia and eliminate the need for reading glasses. One of these new techniques, called PEARL, shows promising results.

PEARL (PrEsbyopic Allogenic Refractive Lenticule) is a procedure that places a small piece of tissue from one part of the cornea into another part. This inlay changes the shape of the cornea, improving near vision.

With the PEARL procedure, the eye surgeon uses a laser to make a small cut in the cornea. A small disc of corneal tissue, called a lenticule, is removed through this cut. The lenticule is sculpted and reshaped with a laser, then placed into a small pocket made in the patient’s cornea.

PEARL may offer safety advantages over artificial corneal inlays for presbyopia. Because the inlay is made of the patient’s own tissue, it is biologically compatible, making it less likely to cause complications. The corneal tissue inlay is expected to allow oxygen and nutrients to flow through the patient’s cornea better than a synthetic inlay, helping to keep the cornea healthier.

Research begin by Soosan Jacob, MD, FRCS, DNB, at Dr. Agarwal's Refractive and Cornea Foundation in Chennai, Tamil Nadu, India.

Using the latest technologies and methods to restore vision in the blinds   The bionic eye devices to restore a sense of vision to people with   retinitis pigmentosa and age related maccular degeneration. The bionic eye consist of a spectacle with centralised camera, external processor and a implant with a microchip and stimulating electrodes surgically placed in the back of the eye ball. The bionic vision system consists of a camera, attached to a pair of glasses,which transmits high-frequency radio signals to a microchip implanted in the eye. Electrodes on the implanted chip convert these signals into electrical impulses to stimulate cells in the retina that connect to the optic nerve. These impulses are then passed down along the optic nerve to the vision processing center of the brain.                                                   ...
