BACKGROUND: The surgical correction of postphacoemulsification aphakia with intraocular lens (IOL) is the most physiological and the most widely used as today. Currently monofocal IOLs are implanted in most cases, but multifocal IOls are also available. The aim of this study was to evaluate visual results and the impact on vision quality of the refractive multifocal IOL (FIL611PV of Soleko) in patients undergoing surgery for bilateral phacoemulsification with IOL implantation.
METHODS: This observational, prospective, single-site study is designed to evaluate the multifocal IOLs FIL611PV (made by Soleko) in patients undergoing phacoemulsification with IOL implantation. Patients were asked to attend at ophthalmologic control visits at 1 day, 7 days, 1 year, 3 months and 6 months after surgery.
RESULTS: The improvement of visual acuity for the three working distances was statistically significant in all cases compared to preoperative status. Binocular uncorrected and corrected visual acuity was better than that monocular, except in the case of natural visual acuity for intermediate distance. The reduction of the additional required to obtain the best binocular visual acuity for near and intermediate distance was statistically significant in both cases. The additional correction required to obtain the best visual acuity for near and intermediate distance resulted lower in case of binocular vision compared to monocular vision.
CONCLUSIONS: Multifocal lenses tested in this study are a viable solution for visual rehabilitation after a cataract extraction surgery that seeks to make phacoemulsification procedure and IOL implantation procedure real refractive measures, in order to improve patient autonomy as much as possible for different working distances. These features are valid depending on the choice of the lens that best suits the patient’s visual demands.
