The Light Adjustable Lens corrects astigmatism, farsightedness, and nearsightedness. Knh rm phn cc c phi l knh gip gim chi hiu qu nht? With the LAL technology, after optimised IOL calculations have been used to achieve the best possible post-operative outcome with the available pre-operative data, biometry and the use of newer and improved formulas, The LAL provides surgeons a means to fine tune refractive power in the post-operative period, thus benefiting from the latest developments in IOL calculations and its unique capability of precise correction of any residual sphero-cylindrical refractive error. They come with a higher price tag, but this is offset by the benefits they offer. But this lens isnt customized before you have it put in your eye. Ultimately, the decision should be made with .

Variations on this then can be done for astigmatism or any shape desired. Ninety-two percent of the eyes treated were within 0.25 D of the targeted refraction and all stable within 0.25 D by last follow-up of up to nine months. Brierley L.

I'm now offered this IOL as an alternative to a monofocal one. The adjustment occurs when all non-attached solutes equally distribute themselves throughout the optic after irradiation with ultraviolet light that causes the photosensitive macromers to polymerise in the irradiated region. There are mainly two potential shortcomings with this technology, the first one is the number of post-operative visits required for the adjustment and lock-in procedures, something that can be managed by a standardised protocol for the post-operative visits and trained staff, since the LDD treatment itself takes usually under two minutes. The most common of these are toric lenses. Comparison of the rotational stability of two toric intraocular lenses in 1273 consecutive eyes. It also was formulated to remain optically clear upon forming an interpenetrating network within the matrix upon irradiation with UV light.4 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.
