Performance of a truncated-edged silicone foldable intraocular lens in Indian eyes

Abstract

Purpose: To study the role of truncated-edged silicone foldable intraocular lenses (IOLs) in preventing posterior capsule opacification (PCO) in Indian eyes. Setting: Cornea and Anterior Segment Service, L.V. Prasad Eye Institute, Hyderabad, India. Methods: This prospective study evaluated 39 Indian patients (39 eyes) with a mean age of 55.4 years who had uneventful implantation of the CeeOn® Edge 911A IOL (Pharmacia). All IOLs were placed in the bag. Except in 4 patients, the capsulorhexis margin overlapped 360 degrees on the IOL optic periphery. The mean follow-up was 10.9 months (range 6.5 to 13.0 months); 32 patients were followed for 1 year. Results: Intraoperatively, posterior capsule fibrosis was noted in 7 patients. Diffuse haze was noted in the IOL optic in 1 patient. Clinically significant PCO did not occur in any case. One patient had clinically nonsignificant (grade 1) PCO at the 6- and 12-month follow-up visits. Although epithelial pearl accumulation (Soemmering’s ring) was seen beyond the edge of the IOL in the 32 patients followed for 1 year, the epithelial pearls were central only in the patient with grade 1 PCO. Significant cell deposits were noted in 1 patient who had fibrinous uveitis at the 1-week postoperative visit; both resolved by 1 month. All eyes achieved a best corrected visual acuity of 20/30 or better. Conclusions: The CeeOn Edge 911A IOL was well tolerated in Indian eyes, and the posterior capsule remained clear. Larger patient groups with a longer follow-up will provide more useful information.
