Purpose
evaluation of the efficacy of multifocal, diffractive intraocular lenses in cataract surgery. Material and methods 20 eyes in 10 patients, mean age 64 ±9 years, included in the study, undergoing phacoemulsification of the cataract with implantation of diffractive MIOL (AcrySof ReSTOR, SA60D3, Alcon). Follow-up was performed for a period of 6 months. Postoperative evaluation performed five times included: visual acuity for distance and near without and with best correction, contrast sensitivity, patient satisfaction in 10-grade scale, degree of independence from glasses and frequency of lighting effects. Results After 6 months from surgery uncorrected distance visual acuity ≥1.0 was achieved in 55% of operated eyes (6/11), and the best corrected in 91% (10/11). Uncorrected near visual acuity in 2-6 months after surgery was achieved in all patients. Contrast sensitivity for spatial frequencies in the range 12 and 18cdg was decreased, but in 6 cdg was normalized after 6 months of observation, and in 3 cdg was normal. Subjective patient satisfaction in 10-grade scale was on average in the first day after surgery 7.9 points and after 6 months 9.3. The necessity to use glasses (30%) and lighting effects had no bearing on subjective patient satisfaction perception Conclusions Multifocal diffractive lens implants are able to restore good visual acuity independent of distance and is effective and safe method in cataract surgery keywords:
