Modern Blade-free Cataract surgery with the precision of the Femtosecond Laser
Cataract surgery today is different in many ways from the cataract surgery 30 years ago. Technological advances in the tools and calculations available have allowed highly specialized surgeons to perform new procedures with much more precise outcomes, less invasive techniques and far shorter recovery times.
Modern Cataract surgery is a relatively quick, out-patient procedure. Most patients are only in the surgery center for a few hours total before going home. Many patients find that after surgery, they are able to function without total reliance on prescription glasses.
Blade Free, Precise Laser Surgery. Dr. Switch uses the most modern techniques, which includes the creation of a small, self-sealing incision through the use of a state of the art femto-second laser called the LenSX™ laser. This means no sutures are needed and all incisions are made with the precision of a computer driven laser. Ultrasound energy, known as phacoemulsification, is utilized to break up the cataract using tiny vibrating waves of energy to remove it from the eye. A new clear lens is placed in the eye where the old cataract was located.
Dr. Switch will use advanced computers and software to calculate the precise lens needed to replace the cataract. This will allow a patient to see clearly in the distance. If no astigmatism is present, the patient will be able to see far away without glasses. Reading glasses will still be needed for objects up close. If Astigmatism is present, glasses will be needed for both distance and close vision even after cataract surgery.
Dr. Switch offers the Toric Lens implant for correction of astigmatism after cataract surgery. In the past, patients with stigmatism would require glasses or contact lenses after cataract surgery. Now, advances in implantable lens technology provide an effective option for patients who have astigmatism in addition to cataracts. The result is correction of both conditions with one procedure.
The AcrySof® ReSTOR® lens is a new technology that allows patients to see near, intermediate and far vision, often without the need for glasses. Using a technology known as “apodization”, the lens offers a range of vision not possible in the past. Dr. Switch will be able to tell you whether you are a good candidate for this new technology.
-Color Vision will be improved after surgery. Often, colors are much more vibrant after surgery.
-Clarity is typically improved. Many people notice that they no longer struggle to read road signs or the fine print on the television.
-Restoration of lost function. Many people wait to have cataract surgery until has affected their ability to drive, do their hobbies, or simply do the many activities of daily living. After surgery, these patients find many of these limitations have been removed and they can return to life the way they remember before their vision was impaired.
Although rare, there are several risks, which may be associated to cataract surgery.
-Infection. Fortunately, due to modern sterilization techniques and the use of powerful antibiotic eye drops before and after the procedure, the risk of infection from modern cataract surgery is extremely low.
-Bleeding. Dr. Switch uses an advanced technique, assisted by a femtosecond laser, to create an incision that is less than 3milimeters at the edge of the cornea where there are not blood vessels. This all but eliminates the risk of bleeding from cataract surgery.
-Swelling. Swelling (edema) of the clear corneal tissue is a common side effect of cataract surgery. This swelling is temporary and often develops within several hours of the surgery. It generally will improve on its own, but drops may be prescribed which speed the resolution of this mild swelling.
-Elevated Pressure. Rarely, the pressures inside the eye will be elevated after surgery. This is a form of post-operative glaucoma and patients complain of a headache around the eye. If this occurs, a pressure lowering eye drop may be temporarily prescribed until the pressure has returned to normal.
-Macular Edema. Very rarely, patients may develop swelling in the back of their eye, which can cause blurry vision. If this complication arises, Dr. Switch will have you continue taking anti-inflammation eye drops until the swelling has resolved.
