SOUTH SIOUX CITY, NE – October 13, 2026 – PRESSADVANTAGE –
Vance Thompson Vision, an ophthalmology practice located in South Sioux City, Nebraska, is offering expanded patient education about the Light Adjustable Lens, a cataract surgery option that allows vision to be fine-tuned after the procedure has been performed. The technology, manufactured by RxSight and approved by the U.S. Food and Drug Administration in 2017, gives cataract surgery candidates in the Siouxland tri-state region access to an intraocular lens that can be modified using ultraviolet light treatments in the weeks following surgery. The current educational focus addresses patient interest in postoperative vision customization at the South Sioux City practice.
Cataract surgery involves removing the eye’s clouded natural lens and replacing it with an artificial intraocular lens, also called an IOL. With conventional intraocular lenses, the prescription power is calculated before surgery using preoperative measurements and biometric data, and the prescription cannot be modified once the lens is implanted. The Light Adjustable Lens is constructed from a photosensitive silicone material that reacts to specific wavelengths of ultraviolet light. After cataract surgery is performed at Vance Thompson Vision in South Sioux City, patients return to the practice for a series of in-office light treatments using the RxSight Light Delivery Device. Each treatment changes the lens curvaturewithin the eye, allowing the surgeon to refine sphere, cylinder, and other aspects of the prescription based on how the patient is actually seeing in real-world conditions. More information about cataract surgery at the practice is available on the Vance Thompson Vision website.
The adjustment protocol generally involves a series of in-office adjustment and lock-in treatments over several weeks, followed by two lock-in sessions that finalize the lens shape so it no longer responds to ultraviolet light. Between treatments, cataract surgery patients in Sioux City, Iowa; Vermillion, South Dakota; Le Mars, Iowa; and Wayne, Nebraska, wear… UV-protective glasses provided by the practice to prevent unintended changes to the lens from incidental sun exposure. The Light Adjustable Lens received FDA approval in 2017 based on clinical data submitted by RxSight and is an FDA-approved intraocular lens designed for postoperative customization through ultraviolet light treatment. The technology has been adopted by ophthalmology practices across the United States as a cataract surgery option for patients who want to be involved in the refinement of their own vision after the natural lens has been removed.
“What makes the Light Adjustable Lens different from every other cataract lens we have used is that the final prescription is determined after surgery rather than before,” said Dr. Spenser Morton, MD, Board-Certified Ophthalmologist at Vance Thompson Vision in South Sioux City. “For cataract patients who have had previous LASIK or PRK, who have astigmatism, or who simply want to evaluate their vision before locking it in, the LAL gives them a level of involvement in their own visual result that traditional intraocular lenses do not offer. Patient education matters because cataract surgery is one of the most common procedures performed in the United States, and the choice of intraocular lens has implications for how a patient sees for many years.”
