How Cataract Surgery Works: A Simple Explanation
Cataract surgery has a long and fascinating history. In ancient Egypt, surgeons used a technique called "couching" to displace the cloudy lens out of the visual axis to restore some degree of sight. The Romans later implemented a method named "needling," which involved breaking down the cataract into fragments to be absorbed naturally.
These early procedures improved vision but did not provide clear sight, as they did not replace the lens. A major revolution came in the 1940s with the invention of the intraocular lens (IOL) by English ophthalmologist Harold Ridley, which replaced the cloudy lens with a clear artificial one. Today, it is one of the most successful and popular procedures used in the optical sector.
Today's Cataract Surgery
More specifically, cataract surgery is one of the most advanced and commonly performed surgeries in the United States. The procedure involves creating small incisions in the eye to remove the cloudy lens, which is then replaced with an artificial lens.
There are three primary methods to extract the lens: phacoemulsification, extracapsular surgery, and femtosecond laser-assisted cataract surgery. In phacoemulsification, the cloudy lens is broken up using ultrasound waves and then suctioned out, making it a minimally invasive procedure with smaller incisions.
Extracapsular surgery involves removing the hard center of the lens through a slightly larger incision and then aspirating the remaining fragments. The artificial lens implanted in place of the natural lens is carefully selected based on pre-surgery eye measurements and the patient's lifestyle needs.
Laser cataract surgery, also known as femtosecond laser-assisted cataract surgery (FLACS), is an advanced technique that uses laser technology to perform several key steps of the procedure.
A femtosecond laser is employed during cataract surgery to create exact incisions in the cornea, soften the cataract, and fragment the cloudy lens before removal. This method allows for more controlled and accurate lens removal, potentially leading to improved outcomes and faster recovery times. Laser cataract surgery also allows for the simultaneous treatment of astigmatism, offering patients a higher quality of postoperative vision.
How Does Cataract Surgery Work?
Led by our skilled surgeons, Southwest Florida Eye Care provides various cataract treatment options, from advanced vision solutions that minimize dependence on glasses to more basic treatments that improve clarity. Laser cataract surgery starts with a detailed eye examination and measurements captured by the femtosecond laser to create a personalized treatment plan.
On the day of the surgery, local anesthesia will be administered to numb your eye, ensuring you remain comfortable throughout. The femtosecond laser will create precise incisions and soften the cataract for easy removal. The surgeon will then remove the cataract and implant an artificial lens tailored to your specific vision needs.
On average, the entire process takes about 5-10 minutes per eye. However, your total time at the surgical center will be longer due to pre-operative preparations and post-operative care. Patients typically expect to be at the facility for approximately two to three hours.
Life After Laser Cataract Surgery
Recovery from laser cataract surgery involves a few postoperative visits to your ophthalmologist to ensure proper healing. During these visits, your doctor will examine your eye, assess your visual acuity, and measure your eye pressure to ensure the eye is healing.
Post-surgery care includes applying prescription antibiotics and anti-inflammatory eye drops several times a day to prevent infection and reduce inflammation. It is recommended to wear sunglasses outdoors to protect your healing eye from UV rays and assist with light sensitivity.
