PRODUCT INFORMATION Alcon Laboratories, Inc. KELMAN® MULTIFLEX™1 III STERILE UV-Absorbing PMMA Single-Piece Anterior Chamber Lenses CAUTION: Federal (USA) law restricts this device to sale by or on the order of a physician. Model Characteristics Chart Model Optic Type Hole Locations Haptic Vault Height (mm) None None None None None None DESCRIPTION Alcon UV-absorbing PMMA single-piece anterior chamber lenses are designed to be positioned anterior to the iris where it should replace the optical function of the natural crystalline lens. However, accommodation will not be replaced. The...

MECHANICAL CHARACTERISTICS 1. The force required to compress the diameter of the anterior chamber IOL 0.5 mm: 0.89 gm for MTA2U (12.0 mm) - 1.13 gm for MTA7U (14.5 mm). 2. The force required to compress the diameter of the lens 0.5 mm less than the original diameter after it has been compressed 0.5 mm for 24 hours at 37°C in saline: 0.98 gm for MTA2U (12.0 mm) - 0.78 gm for MTA7U (14.5 mm). 3. The vault observed after compressing the diameter of the lens 1.5 mm: 0.26 mm for MTA2U (12.0 mm) - 0.29 mm for MTA7U (14.5 mm). The force required to compress the lens 1.5 mm: 2.91 gm for MTA2U (12.0...

CAUTION When considering the implantation of IOLs of powers at extreme ends of the available power range, special consideration should be given to the dimensions of these lenses in relation to the anatomical clearances in the patient’s eyes. The potential impact of factors such as optic central thickness, optic edge thickness and overall lens size on these patients’ long-term clinical outcome must be carefully weighed against the potential benet associated with the implantation of an IOL, and the patients’ clinical progress should be carefully monitored. Under certain circumstances, there...

CALCULATION OF LENS POWER Preoperative calculation of lens power for these anterior chamber lenses should be determined by the surgeon’s experience, preference, and lens placement. Lens power calculation methods are described in the following references: Hoffer, K.J. The Hoffer Q formula: A comparison of theoretic and regression formulas. J. Cataract Refract. Surg. 19:700712, 1993. Holladay, J.T. et al. A three-part system for rening intraocular lens power calculations. J. Cataract Refract. Surg. 14:1724, 1988. Holladay, J.T. et al.
