Light Adjustable Lens (LAL)

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.

I just had my cataract surgery 40 days ago with the Clareon® PanOptix®  trifocal lens, but my vision is not improved at all. My near vision is what I do concern but it is horrible. And, I did not have presbyopia before surgery, but now I am having it after surgery. My doctor recommended me to replace the monofocal lens this Feb. If any chance you could respond to me I would be appreciated. Thank you.

Doctor Krad, thank you so much for your response. Before making an appointment, I would tell you more about my eyes because I am living in Seattle. I had a PRK surgery in 1996 for both eyes. Then I have been having dry eyes, not terribly dry. I am not sure if it is a risk to take my exited motifocal len out because I just did my surgery 40 days ago. For my situation any chance I could have the LAL len. Please advise.


If I have already had cataract surgery with lens implants can I still have this light adjustable lens implanted?
