Eye surgery is also known as ocular surgery performed on eye or its adnexa by ophthalmologists. The eye is a fragile organ, and requires extreme care before, during, and after a surgical procedure. An expert ophthalmologist is responsible for selecting the suitable surgical procedure for the patient, and for taking the essential safety precautions. Mentions of eye surgery can be found in several ancient texts. Today it continues to be a widely practiced type of surgery, having developed various techniques for treating eye problems.
