Two-Year results of cataract extraction with implantation of the hydrophilic acrylic b-lens^®

Purpose: To evaluate the safety and efficacy of a hydrophilic acrylic intraocular lens (B-Lens^®, Hanita, Israel) during a 2-year follow-up period. Setting: Department of Ophthalmology, Meir Hospital, Sapir Medical Center, Kfar-Saba, Israel. Patients & Methods: Slit lamp biomicroscopy, refraction, visual function and patient satisfaction were recorded in 147 patients at 1 week, and at 1, 3, 12, and 24 months after surgery. Results: Nine cases (6%) were associated with partial rupture of the superior haptic intraoperatively, which did not preclude in-the-bag centration of the IOL in all cases. Postoperative complications were mild or reversible and rarely observed. The posterior capsule opacification (PCO) rate increased considerably (from 0.35 to 0.80) from 1 to 2 years but was for the most clinically insignificant; 16 of the 90 cases (18%) with PCO at 2 years had clinically significant opacification of the posterior capsule. No IOL discoloration was observed. BCVA stabilized by the third month and refraction was at the predicted level at two years. Eighty-one of 91 cases (89%) had BCVA equal to or more than 20/40 and 43 of 91 (47%) gained a BCVA of 20/20 at two years. Conclusion: Hydrophilic acrylic B-Lens^® implantation is safe and effective for patients with cataract.
