Multifocal Intraocular Lenses to Correct Presbyopia after Cataract Surgery

Monofocal intraocular lenses are effective in improving vision after cataract surgery but the loss of accommodation is not restored by implantation of these intraocular lenses. Because multifocal intraocular lenses may improve uncorrected distance and near vision, we compared clinical outcome and patient satisfaction after implantation of multifocal intraocular lenses. The study included eight patients who underwent cataract surgery using phacoemulsification and implantation of multifocal intraocular lenses (ReStor, Tecnis). Intraocular power calculation was measured by standard immersion A-scan ultrasonography using Holladay 2 formula, with target hyperopia +0.50 Dpt. Assessments were made preoperatively, and at 1 and 3 months postoperatively, whereas outcome was evaluated by interview. Satisfaction related to preoperative expectations was similar in all study patients. Visual acuity was 0.9 1.0 in 92% of the patients. All patients were satisfied with near vision without glasses. The perceived quality of corrected near vision showed highest correlation with patient satisfaction. Study results suggested that the patients were satisfied with their intraocular lens performance, and most would have the multifocal intraocular lens implanted again. The frequency of spectacle wear was greatly reduced for both distance and near vision.
