To evaluate the outcomes of phacoemulsification with binocular implantation of SA-40N multifocal intraocular lens at the "Hospital de Olhos de Minas Gerais".
The charts of 58 patients (116 eyes) who were submitted to phacoemulsification with binocular implantation of SA-40N multifocal intraocular lens were retrospectively analyzed.
The mean preoperative spherical equivalent was +1.55D (ranging from -4.25 to +6.25D) and after surgery it was -0.59D (ranging from -2.25 to +1.25D). Thirty days after surgery, 94 eyes (81%) achieved 20/20 for better distance corrected visual acuity. For best uncorrected binocular near vision, 29 (50%) patients were able to read J1 and 25 (43.1%), J2. When we compare the best corrected distance vision, before and after surgery, we observed that 68 (58.6%) eyes keep the same best corrected visual acuity, 33 (28.4%) eyes gained lines of visual acuity and 15 (12.9%) lost lines of vision. Regarding complications, 19 (32.7%) reported halos, three (2.6%) eyes had macular edema and five (4.3%) eyes had posterior capsular opacification. Thirty-six patients (62.1%) did not need to use spectacles.
The results of this study indicate that multifocal intraocular lens bring about less dependence on spectacle wear and high patient satisfaction despite some reports of halos.
