Vance Thompson Vision was one of the first practices in the world to complete a successful cataract surgery with the RxSight Light Adjustable Lens (LAL) since its approval by the FDA. This new cataract treatment option is already changing the way both doctors and patients experience cataract surgery.
A cataract develops when the eye’s natural lens becomes hard and cloudy. This causes vision to become dark and blurry, making it difficult to perform everyday tasks.
Cataracts can only be treated through surgery. During surgery, the surgeon removes the defective natural lens and replaces it with an artificial intraocular lens (IOL).
Before surgery, the doctor will take specific eye measurements and use them to estimate the power of the IOL needed to provide the patient with clear distance vision.
The Light Adjustable Lens Difference
The LAL is the only FDA-approved IOL that can be adjusted after implementation. This removes the need for preoperative estimation because the lens can be adjusted after surgery according to the patient’s preference.
How does it work?
A typical IOL is normally made from silicone, acrylic, or plastic. The LAL is made from photoreactive silicone. The doctor will administer light treatments that target specific areas with UV light and adjust the curvature of the lens while it’s in the patient’s eye. When the patient is satisfied with the refraction, the surgeon uses a “lock-in” exposure to preserve the final lens power.
How will the LAL impact future cataract procedures?
Surgeons predict that the LAL will greatly change the world of cataract surgery. Sometimes, new technology can add more training and additional work for doctors. But instead of adding more work, the LAL simply shifts the preoperative process to postoperative. The greater accuracy provided by the LAL is also expected to increase both patients’ and doctors’ confidence in the procedure’s outcomes.
With the LAL, doctors can show patients exactly what their vision options are. Prior to locking in their permanent vision correction power, patients can test what their vision will look like using a contact lens and adjust it to their own personal preference. A normal IOL does not allow this customization. This process can be repeated for additional adjustments, such as more powerful near vision. The doctor can then lock in the final implant power or vision so that the patient can enjoy the result for the rest of their life.
