Traditional cataract surgical treatment is completed using a small blade for an initial cut, followed by a process conducted with a phacoemulsifier. A phacoemulsifier is an ultrasound expedient that vibrates at such a high speed that the cataract is blended or softened into tiny fragments and mildly suctioned out of the eye.
In 2011, the Food and Drug Administration gave endorsement to several laser companies for laser cataract surgical treatment, referred to as femtosecond laser cataract surgical treatment.
Traditional Versus Laser Cataract Surgical treatment
During traditional cataract surgical treatment, a small cut is made in the periphery of the cornea. The opening is made with a metal or diamond blade held by the physician. This self-sealing incision is only about 2 to 2.5 mm long and has a slight vertical and horizontal component so that no stitches are needed.
In laser cataract surgical treatment, with the femtosecond laser, a doctor can view a magnified, high-resolution image given to him or her by a built-in OCT device. A peripheral incision can then be made deliberately without taking the surgeon's experience into account. This laser-designed incision is safer and seals better than a surgeon-made incision.
