Florida Vision is always looking for ways to improve the safety and efficacy of our procedures. One way that may enhance the results of cataract surgery is to incorporate a femtosecond laser, which replaces a handheld instrument for several critical steps of the procedure. Many cataract surgeons, feel that lasers may enhance the cataract removal process and lead to better surgical outcomes. Traditional cataract surgery is over 99 percent safe and effective. Using a laser may heighten the safety and precision of treatment.
The steps of laser cataract surgery are almost identical to thoseof traditional surgery, except that a femtosecond laser is used during several key portions of the operation.
First, the femtosecond laser is used to create the initial incision in the cornea, the surface of the eye, to access the capsule that holds the lens. The incision is carefully planned with a three-dimensional image of the eye (made from optical coherence tomography technology); then made expertly with the laser. The goal is for the incision to seal itself after surgery to reduce the risk of infection
Then, the femtosecond laser creates an opening in the front portion of the lens capsule through which the cataract can be removed. This part of the procedure, called the capsulorhexis, is important for both the proper removal of the cataract and subsequent positioning of the IOL (Intraocular lens). If the IOL is incorrectly placed, it affects the visual outcomes of cataract surgery.
Finally, the femtosecond laser gently softens and fragments the cataract for easy removal. Using laser energy instead of ultrasound energy reduces the risk of overheating the eye and possibly burning the incision. It is also helpful for preserving the capsule so it can hold the IOL firmly in place.
Florida Vision also uses the ORA (Optiwave Refractive Analysis) system during cataract surgery to customize treatment. This technology is designed to help calculate the appropriate intraocular lens implant for each individual patient. Selecting the right IOL is critical to achieve the best possible vision without the need for prescription glasses. When we use the ORA system, patients can be confident that they are receiving the best possible vision after cataract surgery.
The ORA system takes intraoperative measurements of the eye after the clouded natural lens has been removed and before the intraocular lens has been inserted. It does not touch the eye, but it takes the measurements while the eye focuses on a special light. These measurements are then plugged into a mathematical formula to help determine the proper intraocular lens. This improves the precision of the selection of the best IOL to give you better vision without wearing prescription lenses.
