Crystalens-Focusing Lens Implant |
ataract surgery has undergone a remarkable evolution over the many years since itís inception. At first, a large incision had to be made so the natural lens could be removed and an Intraocular Lens (IOL) could be inserted. The first IOLs were placed in the anterior section of the eye in front of the iris. This dramatically improved the procedure from the time when there were no implants. The problem with these anterior segment IOLs were that they vibrated resulting in endothelial (inner most layer of the cornea) damage often requiring corneal transplants.
The next big advancement was the development of the posterior IOL. This implant was place behind the iris thus eliminating the vibration and therefore protecting the cornea. These still needed a large incision requiring 7 sutures. The next big step forward was Phacoemulsification...

G.A.P.P. an Intralase LASIK Complication
ASIK has come a long way since it was first performed many years ago. In the beginning, a lathe was used to cut a flap in the anterior section of the cornea, and the underlying tissue was then ablated, or burned away with a laser. While the lathe was gradually improved, and the technique refined, there were still issues with the blade. For one, it created an irregular flap that was thicker at the edge then in the center. This was the source for blurred vision, and additional problems if the flap moved.
A major development was the introduction of Intralase. This brought LASIK forward into the 21st century. Intralase employs a laser to actually create the flap. In doing so, the flap is equal in thickness 360 degrees around, thinner and more predictable. The edges fit better and thus heal faster and cleaner. However, with every improvement comes potential for trouble...

Ramsay Hunt Syndrome and the Eyes
amsay Hunt Syndrome is a complex condition, with multiple signs and symptoms caused by the reactivation of the Varicella-Zoster virus. This virus lies dormant in the dorsal root ganglion of the spinal cord after first appearing as chicken pox in children. It rarely, if ever will result in any disorder in children, but will appear as a complication of shingles in adults. The older the individual the worse the condition will be.
In adults, the main feature of the disease is facial paralysis appearing as Bellís Palsy through damage to the 7th cranial nerve. This paralysis will make the lower eye lid droop on the affected side of the face. In doing so, it may lead to corneal drying, scarring, pain and even ulceration. Proper treatment of the underlying condition is a must...
