PURPOSE: To demonstrate that in case of absence of capsular support intraocular lens (IOL) scleral fixation is both effective and stable over years. METHODS: A total of 13 eyes from 13 patients who underwent an IOL scleral fixation according to Lewis suturing technique between January 2001 and December 2008 were studied. Patients underwent a complete ophthalmologic evaluation. The IOL stability was assessed using slit-lamp and anterior segment optical coherence tomography (AS-OCT) examination. The IOL stability was evaluated in terms of centration and tilting. All the knots were photographed and their integrity assessed. RESULTS: Follow-up was 60-129 months. Eleven knots appeared evident and undamaged, 6 knots were eroded, and 9 knots were not detectable. All IOLs were stable in the sulcus. Two patients presented a slight decentration of the IOL at the slit-lamp examination, while the AS-OCT demonstrated slight tilting of the lenses in 4 patients. CONCLUSIONS: The Lewis technique for IOL scleral fixation is an optimal surgical technique in case of absence of capsular support. No IOL luxation in the vitreous chamber has been reported; only 2 of the 10 patients with at least one eroded knot presented a minimal decentration of the lens with no influence on visual acuity. Although knot erosion is not an uncommon occurrence, IOL remains stable in the long term, probably due to a fibrotic process around the suture, and the IOL haptics, which prevent IOL dislocation.
