Premium Lens Implants
Dr Willams uses both the Restor multifocal and the Tecnis multifocal lens implants (IOLs). These lenses are made by Alcon and AMO respectively and they use a physical property called diffraction to allow patients to see at both near and far. The newest versions allows patients to also see intermediate distances. They are best enjoyed when placed in both eyes. Many patients receiving these lenses notice “halo vision” at night around point sources of light. This usually does not prevent patients from driving at night. If your career or lifestyle requires frequent night driving, it may not be the best choice for you. This lens will allow you to minimize eyeglass wear but not eliminate it entirely. There may be limited circumstances where glasses are still required. LASIK surgery is sometimes required afterward to maximize vision potential. In studies 90% of patients with these lenses rarely or never wear glasses postoperatively. While they can be used in some eyes with low degrees of astigmatism if you have moderate corneal astigmatism these lenses may not be the best choice for you. Use of premium lenses incurs additional costs over standard implants.
Toric lens implants
Certain patients will benefit from toric lens implants which correct astigmatism. These can be placed into the eye erasing up to 3 diopters of astigmatism. This creates sharper, clearer vision without glasses. They are preferable to the incision method of astigmatism correction (limbal relaxing incision or LRI) although this is sometimes also required for patients with high degrees of astigmatism over 3 diopters.
