As the macromers migrate centrally, this portion of the lens swells and refractive power increases to correct hyperopia.4 The rationale for the invention of the Light Adjustable Lens was to tackle important issues that lead to unsatisfactory uncorrected visual outcomes in cataract surgery such as inaccurate biometry, unpredictable effective lens position, and wound healing, given that cataract extraction is one of the most common surgeries undertaken worldwide. Lee BS, Chang DF. Haigis W, Intraocular lens calculation in extreme myopia. Pros: Prime lenses usually delivers sharper images quality overall, compared to other different types of lenses. Lundstrom M, et al. Particles or monomers can easily migrate within the lens and do so when exposed to ultraviolet light. He added that to flatten the center of the lens to treat myopia, you would expose the light to the periphery of the lens and the monomers would migrate there, and subsequently thicken the periphery of the implant and flatten the center. In fact, 95% of our laser cataract patients are seeing 20/25 or better! Dr. Maloney said that with this lens, the patient has routine cataract surgery, and several weeks postop, instead of prescribing spectacles, the surgeon exposes the LAL to a precise pattern of light that changes the shape of the lens to correct the residual refractive error. The decision of whether to go with light adjustable lenses or traditional lenses ultimately depends on your individual needs and preferences. It helps you to detect if you have cataracts or not.

From everything we can tell with long-term results, in our centers and long-term data outside the U.S., the IOL remains stable.. A day after the final treatment , no further changes can be made in the lens power. A much smaller percentage achieves optimal vision without spectacles.1 The variables that affect post-operative UCVA include imprecise IOL power determinations, pre-existing corneal astigmatism, surgical induced astigmatism and previous corneal refractive surgery.3236 As light enters the eye "diffractive MFIOL's" split this light into distance and near focal points for distance and near vision. The optic is irradiated either in the central region or the peripheral region based on the power change required. Another advantage of the Light Adjustable Lens is that its for patients with astigmatism thats at least 0.75 diopters. With LALs, its possible to achieve a level of precision that was never possible before.
