Traditional vs. Laser Cataract Surgery
Laser Cataract Surgery uses a femtosecond laser to perform many of the surgical steps that were traditionally performed by hand. The precise, reproducible steps performed by the laser mean better lens positioning, less trauma to the eye, and more predictable visual results which are especially important with LifeStyle Lens Implants.
Laser Incisions vs. Blade Incisions
To begin, a stair-step incision is created on the edge of the cornea with the laser instead of with a blade. The incision is self-sealing and rarely needs suturing.
The laser then creates an opening in the thin capsular membrane that surrounds the natural lens to provide an opening to remove the cataract. Studies have shown that less than 10% of manual capsulorhexis, which is made with a bent or shaped needle, have been able to achieve the same accuracy that is produced with laser cataract surgery.
The laser also softens the nucleus as it is divided into manageable pieces, thereby allowing the cataract to be removed using less ultrasound energy. This is beneficial because there is less inflammation during surgery, making the procedure less traumatic to the eye.
