As cataract surgery has evolved and small incision phacoemulsification has become the dominant procedure, surgeons have been on a continual quest to provide patients with an emmetropic visual outcome.1 As visual outcomes have improved over the years with developments in biometry and IOL calculation formulas,2931 patients have become more demanding, expecting at least emmetropia if not presbyopic correction. The main issues with this lens is that it only allows for spherical adjustments and that it requires a second intraocular procedure two weeks after phacoemulsification and IOL implantation for adjustment.38 Coastal Vision Medical Group is the first practice in Orange County to provide the Light Adjustable Lens (LAL).
