LASER CATARACT SURGERY(1988)

Bath devises a laser instruments to facilitates lens removal from the eye.

The removal of natural lens of the eye (also called "crystalline lens") that has developed on opacification, which refers to as a cataract is called cataract surgery. With low complication rate well over 90% of operation are successful in restoring useful vision. 

In nearly all circumstances, pointing a laser at your eye is a bad thing, but if you have cataracts it may just restore you sight. cataracts are a leading cause of blindness. The disorder occurs when the part of the eye that focuses light known, not surprisingly, as the lens turns cloudy, this is a process that occurs in almost all of us if we live long enough. Unfortunately, current there is no viable way to make a cloudy lens transparent again, and so ophthalmologists are forced to resort to other means to all alleviate the problem.

The current method of dealing with a cataract is to remove the lens of the eyes. One problem is taking out the lens in its entirety requires a rather large incision into the eye in order to remove it. Ophthalmologist have long felt that it was more appropriate to find a method to break up the lens, which allow them to remove it through a smaller incision. This process, known as emulsification of the lens, was at one time done simply by grinding up the lens, but this method was subsequently replaced by a tool that transmits ultrasonic waves and uses sound energy to break up the lens. The resulting fragments are then vacuum extracted from eye.

All this may change with a tool invented by Dr. Patricia Bath .Dr. Bath postulated that lasers could be used to emulsify the lens of the eye as well, and she developed a model for a laser instrument to be used in removing cataracts. She received a patent for his invention in 1988. After much trial and error it turns out that Dr. Bath is correct, and her system may yet benefit cataract patients everywhere.

The sign of complication following cataract surgery are decreasing vision, increasing pain, increasing redness, swelling around the eye, discharge from the eye, new floaters, flashes of light, or changes in your field of vision.
