This element allows the optical part of the IOL to move along the optical axis. These lenses make it more comfortable when you are out in bright sunlight but are clear when you are indoors. The study found that the irradiation protocol for adjustment and lock-in of the LAL does not seem to add to the endothelial cell damage caused by the cataract surgery, indicating the protocol is safe to the corneal endothelium. Adjustable IOLs will allow patients to use trial lenses or even trial soft contact lenses to make this decision postoperatively, Dr. Chang said. Lets find out! Savini G, Barboni P, Carbonelli M, Hoffer KJ, Accuracy of Scheimpflug corneal power measurements for intraocular lens power calculation. The lock-in treatments are necessary to consume all remaining photoactive macromer in the LAL and stabilise the adjusted lens power. The IOL has UV light filtering material concentrated along the posterior aspect of the optic which protects the retina during overexposure to UV radiation during adjustments and lock-in treatments. Closed This technology also comes with an extra fee for the work that is involved, which Dr. Waltz estimated could be $5,0008,000 per eye.
