First Bifocal Light Adjustable Lens (LAL) Surgery

The Light Adjustable Lens (LAL) is a type of intraocular lens implant (IOL) that is made from a light sensitive polymer. The LAL can be used as part of Cataract Surgery to correct vision. It is unique because it allows the Cataract Surgeon the ability to adjust or “fine tune” the prescription for the patient in order to get the best possible visual results. The London Eye Hospital has now performed the world’s first bifocal Light Adjustable Lens (LAL) eye surgery. By using a digitally computer controlled beam of light delivered through the patient’s pupil, the Cataract Surgeon is able to precisely correct even the finest imperfections in the patient’s prescription. The precision is so great it can even correct the minor imperfections necessary to provide treatment of aberrations and create bifocal correction. Because the fine tuning adjustment is delivered through the pupil it doesn’t carry the surgical risks of a lens implant exchange procedure and it can be adjusted multiple times throughout the patient’s lifespan without additional surgery in order to keep providing the best vision.
