Choosing an IOL before having cataract surgery involves a certain amount of guesswork. Additionally, they can only be adjusted within a certain range, so if your prescription changes drastically, you may need to purchase a new pair of lenses. The ability to correct these refractive errors allows patients to experience clear vision without glasses after cataract surgery. Because you can have the Light Adjustable Lens adjusted after healing from cataract surgery, it means more accurate results. The next challenge for this technology is to address presbyopia.14,21 For this purpose, the easiest, already available option is monovision. Lichtinger A, Sandstedt CA, Schwartz DM, Chayet AS, Correction of astigmatism after cataract surgery using the light adjustable lens: a 1-year follow-up pilot study. The eye doctors at Coastal Vision are uniquely qualified and dedicated to offering cataract patients top-of-the-line technology. Paulig S Binovision, A Novel Approach to Presbyopia Correction. Prior to surgery, routine baseline measurement to determine the monofocal base power is performed. Most patients usually need 2 or 3 sessions each. 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. Minor complications include temporary dryness of eye and activation of an preexisting herpetic eye disease. The clinical trial results were remarkable, he said. This technology comes with an extra fee for the work that is involved. The past three decades has seen a spirited, noble race to intraocular lens perfection.

Formulated into the silicone matrix are a photoreactive macromer, photoinitiator and ultraviolet (UV) absorbers. Digital screens peak around 455nm for most devices. They clearly minimize the error from inaccurate biometry, power calculation, and post-implantation IOL movement. . Wang L, Booth MA, Koch DD, Comparison of intraocular lens power calculation methods in eyes that have undergone LASIK.

On the other hand, the LAL is highly customizable since a patient's prescription is applied to the lens after surgery. A big advantage of multifocal lenses, said Stephen G. Slade, M.D., Houston, is that the ReSTOR lens (Alcon, Fort Worth, Texas) has the best near vision of any of the lenses. My guess is that an extended depth of focus or multifocal pattern to resolve presbyopic complaints would be the next order of interest from surgeons and the company, he said. Jeffrey D. Horn, M.D., Nashville, agreed, "The ReSTOR is definitely the best near vision lens on the planet.". Thank you! It helps you to detect if you have cataracts or not. . A study by Hengerer et al.18 evaluated the LAL in 15 patients with axial hyperopia (with or without toric component) with a follow-up of 12 months, 93 % of the eyes achieved +/-0.5 D of the targeted refractive correction and all except one eye showed <0.25 D change between the one month post lock-in and the 12 month visit. Most multifocal lenses have breaks that make transitions between various distances a little rough.

The LAL incorporates photosensitive molecules known as macromers embedded uniformly in a silicone matrix. Two weeks after surgery, the doctor measures your vision, and then shines a . If the doctor wishes to add power in order to treat hyperopia then the central portion of the lens is illuminated and if there is a need to take away power then the peripheral part of the optic is irradiated to increase the peripheral curvature of the lens resolving the myopic refractive error. You wont need any more light treatments! The lock-in treatments are necessary to consume all remaining photoactive macromer in the LAL and stabilise the adjusted lens power. Hengerer FH, Hutz WW, Dick HB, Conrad-Hengerer I, Combined correction of axial hyperopia and astigmatism using the light adjustable intraocular lens.
