Benefits:

• Longest clinical history. First Artisan phakic IOL implanted on November 2, 1986
• One size fits all. No sizing required. Other Phakic IOLs need sizing for a proper fit
• Extremely versatile Designed for aphakia, Myopia, Hyperopia, Iris Reconstruction and Pediatric applications.
• Reversibility of fixation. Easy to reposition or to exchange
• Optimal distance to crystalline lens
• Optimal distance to corneal endothelium
• High predictability. 70% of patients obtain a refractive result within 1 D of the predicted power
• Excellent centration. Once fixated, the lens will not decenter
• Integrity of vascular supply maintained. Shown in fluorescein angiographic studies
• Pupil dilation not inhibited. Fixation arms attached to immobile iris
• Maximal visibility of Artisan PIOL 

Artisan PIOLs are intended for patients:

• Who are 18 years of age or older
• With stabilized myopia or hyperopia, as demonstrated by a change of less than or equal to 1.0 diopter for at least 12 months prior to the preoperative examination
• Without eye diseases
• With a general healthy condition
• With a minimal endothelial cell density according to the subject’s age:
       18 to 25 years of age 2800 cells/mm2;
       26 to 30 years of age 2650 cells/mm2;
       31 to 35 years of age 2400 cells/mm2;
       36 to 45 years of age 2200 cells/mm2;
       > 45 years of age 2000 cells/mm2;

 
Contraindications:

• Endothelium cell counts less than 2000 cells/mm2

• IOP > 21 mm Hg.
• Retinal detachment or family history of retinal detachment
• Any form of cataract
• Recurrent or chronic iritis
• Chronic or recurrent uveitis
• Pre-existing macular degeneration, retinopathy
• Fixed pupil size > 4,5 mm

• Scotopic pupil size > 6.0 mm (5 mm PIOL optic) or 7.0 mm (6 mm PIOL optic)
• Abnormal cornea
• Iris atrophy
• Diabetes
• No useful vision in fellow eye
• Surgical difficulty at the time of surgery which might increase the potential for complication
• Patients under 18 years of age
• Pregnant or nursing patients
