The light adjustable lens (LAL) implant is a type of artificial intraocular lens (IOL) that can be adjusted after it has been implanted in the eye. It is used in refractive lens exchange (RLE) surgery, which is a procedure that involves replacing the natural lens of the eye with an artificial lens to correct vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It is also used in Cataract Surgery.
The LAL implant is made of a special material that can be activated by light. After the implant has been placed in the eye, the patient undergoes a series of special light treatments called "LDD treatments" or "lens adjustments." These treatments use a device that emits a specific type of light to activate the LAL implant. The amount of light that is emitted can be adjusted based on the patient's individual vision needs. The implant changes shape in a predictable way in response to the light.
One of the main benefits of the LAL implant is that it allows the surgeon to fine-tune the patient's vision after the surgery, allowing patients to achieve 20/20 far vision without glasses more frequently than when compared to other lens implants. This is because the LAL implant can be adjusted based on the patient's visual needs. This can help to improve the accuracy of the vision correction and reduce the need for glasses or contact lenses after the surgery.
The LAL implant has shown promising results in clinical trials and is generally considered to be safe and effective. As with any surgical procedure, there are risks involved. It is important to discuss the potential risks and benefits of the LAL implant with a qualified eye doctor before deciding whether it is right for you.
