[Results of the intraocular lens SI-30 implantation]

clinical evaluation of the flexible silicone intraocular lens SI-30 (Allergan).

retrospective study over 3 years of 2000 implantations of the SI-30 IOL. The lenses were inserted through a 3.2 mm scleral tunnel and placed in the capsular bag after continuous circular capsulorhexis and phacoemulsification.

visual outcome was excellent. Without other causes of impaired vision, 99% of patients regained a visual acuity of 20/30 or better after 1 month. Induced astigmatism was unsignificant: 0.4 D; preop., 0.9 D. at day 7, 0.4 at 1 month, 0.5 D. at 1 year. A disinsertion of the inferior haptic occurred in 2 cases during the insertion manoeuver. More specific postoperative complications consisted of pigmented deposits (less than 1%), pupillary capture (4 cases), and capsule contraction associated with small size capsulorhexis. Aspecific complications were: cystoid macular oedema (3% at 1 month, less than 1% afterwards), chronic uveitis (0.6%), acute uveitis (1 patient).

implantation of the SI-30 silicone lens is safe and gives the patient the benefits of a small, non enlarged, and sutureless cataract incision. The postoperative follow-up must take in account the properties of the lens.
