Light-Adjustable Lenses are here
The Light Adjustable Lens (LAL) is an innovative intraocular lens (IOL) used in cataract surgery, offering unique advantages over traditional fixed-power lenses. Unlike standard IOLs, the LAL allows for postoperative adjustments to optimize vision without the need for additional surgery.
One significant advantage is its adaptability to individual variations in eye anatomy, particularly in cases where preoperative calculations may be less accurate, such as after refractive surgeries like LASIK or with irregular corneas. The LAL is especially beneficial for those seeking monovision, fine-tuning each eye for optimal near or distance vision.
The technology behind the LAL involves light-sensitive molecules within the lens, which can be adjusted using an external UV light beam. This non-invasive process allows for precise modifications to the lens shape, addressing issues like astigmatism, nearsightedness, or farsightedness. Temporary UV blocking sunglasses are provided during the adjustment period to protect the lens from excess UV exposure.
Postoperative adjustments are quick, painless, and conducted in-office using a light delivery device. The initial adjustment occurs several weeks after cataract surgery, with subsequent sessions based on the doctor’s assessment. Up to three adjustments are possible, although some patients may require only one. Following optimization, two final “lock-in” treatments ensure the lens remains stable. Once locked in, no additional protection from sunlight or UV light is necessary.
Due to its postoperative adjustability, many patients opt for simultaneous surgery on both eyes. The LAL offers a groundbreaking solution for personalized vision correction, providing patients with a hassle-free and effective way to achieve optimal visual outcomes.
