In order for the eye to function properly, resulting in good vision, light must reach the retina, which is the nerve layer that is located at the back of the eye. The retina then sends signals to the brain, which interprets the signals into an image. For this to happen, the light must pass through the lens and reach the retina unimpeded. When cataracts develop, the light cannot pass through the eye as it should. Cataracts are cloudy sections of lenses that develop in many people’s eyes. When they are present, the pathway for light to pass through clearly is blocked. Cataract surgery then becomes necessary in order to restore vision to its proper level.
When cataract surgery is performed, the surgeon removes the clouded lens and replaces it with an artificial one. The artificial lens is called an intraocular lens implant (IOL). Traditional cataract surgery may be done by one of two methods. The first one requires a small incision. Ultrasound is then used to break the lens so that only small pieces of it remain. The other method involves opening of the lens capsule with the lens being removed in one piece. This method, however, is the lesser utilized of the two.
Laser assisted cataract surgery via LenSx is an improved method of conducting the procedure. With this method, a higher level of precision is achieved. In addition, the equipment is able to scan the eye to accurately measure and map it. This allows for a lens placement with an accuracy that is not achievable with traditional surgical methods. The laser can work with smaller incisions. It also breaks up the cataract in a way that requires less ultrasound energy. In addition, this method of laser assisted cataract surgery can correct astigmatism at the same time.
The laser assisted method allows the surgery to be performed with the use of fewer instruments. There is usually less swelling and a faster recovery time as opposed to the traditional methods. Plus, it is done as an outpatient procedure.
If your vision seems to be getting cloudy, you may want to have the condition evaluated by the experts at Live Oak Ophthalmology. It may be that you will not need surgery for some time. On the other hand, if surgery is recommended, you may want to inquire about the availability of the LenSx method for laser assisted cataract surgery. If you have been told that the surgery is elective on your part, the improved method and its associated accuracy of lens placement and faster recovery time may be enough to make you decide to go ahead with the procedure so you can begin to enjoy improved vision.
