New Bifocal Intraocular Lens

One of the main complaints that patients have had with the Alcon ReStor Intraocular Lens was the close working distance and poor intermediate vision found with this lens. The near focal point of this implant is around 13 inches which forced patients to hold reading material much closer than they may have been accustomed to. This lens also did not perform well at the computer or when used for other intermediate tasks such as looking at prices on store shelves etc. Alcon has addressed these problems with a new model ReStor which has a near focal length of approximately 16 inches. In the recent FDA clinical trial of the AcrySof IQ Restor IOL +3.0 D (Alcon Laboratories, Inc., Fort Worth, TX), patients achieved the same superb distance and near vision with this lens as those who received the AcrySof IQ Restor +4.0 D lens (Alcon Laboratories, Inc.). As an added benefit, compared with the +4.0 D model, the +3.0 D design dramatically improved patients' intermediate vision at 50, 60, and 70 cm .
