LIZARS OPERATION Meaning and
Definition
-
Lizar's operation refers to a surgical procedure named after William Lizar, a Scottish surgeon who developed and popularized the technique in the 19th century. This procedure is predominantly performed in ophthalmology for the treatment of certain eye conditions.
Lizar's operation involves the removal of the eye's natural lens, known as a cataract, which has become opaque or cloudy. The operation is typically performed under local anesthesia, and a small incision is made on the outer layer of the eye. Through this incision, the surgeon gains access to the lens inside the eye.
The cloudy lens is carefully extracted using specialized instruments. Following the removal, an artificial intraocular lens (IOL) is inserted into the eye to replace the natural lens's function. The IOL is selected based on the patient's eye measurements and can help restore clear vision by focusing light rays onto the retina.
Lizar's operation is considered a significant advancement in the field of ophthalmology as it provides a long-term solution to improve visual acuity and treat cataracts. The procedure can help alleviate symptoms associated with cataracts, such as blurred vision, difficulty seeing in low light conditions, and sensitivity to glare.
However, it is worth noting that Lizar's operation is a complex surgical procedure that requires precision and expertise. Patients considering this procedure should consult with an ophthalmologist to determine if they are suitable candidates and to discuss potential risks and benefits.
