MODE OF ACTION These posterior chamber intraocular lenses are intended to be positioned only in the posterior chamber of the eye. INDICATIONS These posterior chamber intraocular lenses are indicated for the replacement of the human lens to achieve visual correction of aphakia in adult patients following cataract surgery. Many of these lenses are intended for placement in either the capsular bag or the ciliary sulcus. Lens models LX10BD, MZ40BD, MZ60MD and MZ60PD are intended for placement in the capsular bag. The surgeon should consider both overall length and optic diameter (see MODEL CHARACTERISTICS Chart) as well as the individual patient’s physiology and needs in determining optimal placement for a specifi c lens model.

CAUTION Special consideration should be given to the dimensions of lens Models MZ60MD and MZ60PD at the extreme ends of the power range in relation to the anatomical clearances in the patient’s eye. The potential impact of factors such as optic central thickness, optic edge thickness and overall lens size on a patient’s long-term clinical outcome must be carefully weighed against the potential benefi t associated with the implantation of an intraocular lens. The patient’s clinical progress should be carefully monitored. Patients with any of the following conditions may not be suitable candidates for an intraocular lens because the lens may exacerbate an existing condition, may interfere with the treatment of a condition, or may pose an unreasonable risk to the patient’s eyesight. Careful preoperative evaluation and sound clinical judgment should be used by the surgeon to decide the benefi t/risk ratio before implanting a lens in a patient with one or more of these conditions:1. Congenital bilateral cataracts.2. Recurrent anterior or posterior segment infl ammation of unknown etiology.3. Patients in whom the intraocular lens may interfere with the ability to observe, diagnose, or treat posterior segment

diseases.4. Surgical diffi culties at the time of cataract surgery which might increase the potential for complications, (e.g., persistent

bleeding, signifi cant iris damage, uncontrollable positive pressure, or signifi cant vitreous loss).5. Patients having only one eye with potentially good vision.6. Medically uncontrollable glaucoma.7. Corneal endothelial dystrophy.8. Proliferative diabetic retinopathy. NOTE: Implantation of these posterior chamber intraocular lenses should not be performed in patients under eighteen

years of age.

WARNINGS1. As with any surgical procedure, there is risk involved. Potential complications accompanying cataract or implant surgery

may include, but are not limited to the following: lens dislocation, manifestations of infl ammation, corneal endothelial damage, infection (endophthalmitis), retinal detachment, vitritis, cystoid macular edema, corneal edema, pupillary block, cyclitic membrane, iris prolapse, hypopyon, and transient or persistent glaucoma.

2. The safety of intraocular lens implants has not been determined in patients with preexisting ocular conditions (chronic drug miosis, glaucoma, amblyopia, diabetic retinopathy, previous corneal transplant, previous retinal detachment, and/or iritis, etc.). Physicians considering lens implants in such patients should explore the use of alternative methods of aphakic correction and consider lens implants only if alternatives are deemed unsatisfactory in meeting the needs of the patient.

-4-

3. The long-term effects of intraocular lens implants have not been determined. Therefore, physicians should continue to monitor patients postoperatively on a regular basis.

4. Patients with preoperative problems such as corneal endothelial disease, abnormal cornea, macular degeneration, glaucoma, and chronic drug miosis may not achieve the visual acuity of patients without such problems. The physician must determine the benefi ts to be derived from lens implantation when such conditions exist.

5. Patients who experience surgical complications associated with the cataract extraction procedure (posterior capsule rupture, detached Descemet’s membrane, anterior chamber bleeding, and vitreous bulge or loss), may experience a higher incidence of infl ammatory responses that are generally transient in nature.

6. Patients who experience surgical complications (such as macular edema, iritis, corneal edema, vitritis, retinal detachment, and lens dislocation) may experience poor visual outcome.

7. A secondary iridectomy for pupillary block may be avoided if one or more iridectomies are performed at the time of IOL implantation (Willis, et al., 1985).

8. The physician should be aware that there is a lack of knowledge and data available regarding the long-term effects of intraocular lenses in younger patients.

9. The safety and effectiveness of a posterior chamber lens, if placed in the anterior chamber, has not been established. Implantation of posterior chamber lenses in the anterior chamber has been shown in some cases to be unsafe (Girard, et al., 1983).

10. All convexoplano and mensicus lenses should be implanted with the convex surface anterior. Plano-concave lenses should be implanted with the plano surface anterior. Care must be taken to ensure that lenses with biconvex optics are properly oriented when being implanted.

11. Lens decentration may result in glare or other visual disturbances. When implanting a narrow or small optic lens, it is recommended that capsulorhexis be performed.

12. Lens models MZ60MD and MZ60PD are not intended, nor should they be used, for clear lens exchange.

PRECAUTIONS1. Do not resterilize these intraocular lenses by any method. (See RETURNED GOODS POLICY).2. Do not store intraocular lenses at temperatures over 45°C (113°F).3. Use only sterile intraocular irrigating solutions (such as BSS® or BSS PLUS® solution) to rinse and/or soak lenses.4. Rubber gloves must not be dusted with powder; polymethylmethacrylate plastic has an affi nity for particulate matter.5. A high level of surgical skill is required for intraocular lens implantation. The surgeon should have observed and/or assisted in

numerous implantations and successfully completed one or more courses on intraocular lens implantation before attempting to implant intraocular lenses.

CALCULATION OF LENS POWER Preoperative calculation of lens power for these posterior chamber intraocular lenses should be determined by the surgeon’s experience, preference, and lens placement. Lens power calculation methods are described in the following references:

DIRECTIONS FOR USE1. Examine the label on the unopened package for model, power, proper confi guration, and expiration date.2. After opening the cardboard storage container, verify lens case information (e.g., model, power, and serial number) is

consistent with information on outer package labeling.3. To remove the lens, open the pouch and transfer the case to an aseptic environment. Carefully open the case to expose the

lens. A smooth, fi ne forceps is recommended (e.g. Kelman-McPherson) to remove the lens from the lens case by placing one blade under the optic through the access slot. Gently grasp the optic and carefully remove the lens, taking care not to catch or damage the haptics. The lens may be rinsed in sterile intraocular irrigating solution (such as BSS® or BSS PLUS® solution) prior to implantation.

NOTE: Prior to insertion, the lens should be carefully examined to ensure that particles have not adhered during handling.

PATIENT REGISTRATION AND REPORTING Each patient must be registered with Alcon Laboratories, Inc. immediately following implantation of one of these lenses. Registration is accomplished by completing the Implant Registration Card that is enclosed in the lens box and mailing it to Alcon Laboratories, Inc. using the postage paid envelope provided. Patient registration is essential for Alcon Laboratories, Inc. long-term patient follow-up program and will assist us in responding to adverse event reports. The Patient Identifi cation Card included in the package is to be completed and given to the patient, together with instructions to keep the card as a permanent record to be shown to any eye care practitioner the patient consults in the future. Adverse events that may reasonably be regarded as lens-related and that were not previously expected in nature, severity, or degree of incidence should be reported to Alcon Laboratories, Inc.

Fifty-one (10.1%) cohort patients receiving the non-UV-absorbing lenses (CR-1, GR-1, SM-1) experienced one or more of the above complications. However, these complications occurred early in the postoperative time frame and appear to be associated with the cataract extraction. Ten patients (2.0%) were reported to have these complications 12-14 months after surgery. Ninety-one (17.9%) cohort patients receiving UV-absorbing lenses (KR2U, SK21U, S2BU) also experienced one or more of these complications. Again however, the complications occurred early in the postoperative time frame and appear to be associated with the cataract extraction. Six patients (1.2%) were reported to have these complications 12-14 months after surgery.NOTE: Cumulative refers to any complication reported at any time during the clinical study. Persistent refers to any complication reported at 12-14 months.
