Abstract
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.Monofokalne intraokularne leće su učinkovite u poboljšanju vidne oštrine nakon operacije katarakte, ali se gubitak akomodacije ne može vratiti ugrađivanjem ovih leća. Budući da multifokalne intraokularne leće poboljšavaju vidnu oštrinu na daljinu i blizinu, usporedili smo kliničke rezultate i zadovoljstvo bolesnika nakon ugradnje multifokalnih intraokularnih leća. U istraživanje je bilo uključeno osmoro bolesnika operiranih metodom fakoemulzifikacije, kod kojih je ugrađena multifokalna intraokularna leća (ReStor, Tecnis). Aksijalna duljina je mjerena imerzijskom tehnikom A-scan uz primjenu formule Holladay 2, a željena poslijeoperacijska refrakcija je bila do +0,50 Dpt. Bolesnici su pregledani prijeoperacijski, te 1. i 3. mjeseca poslijeoperacijski, uključujući intervjue. Zadovoljstvo u odnosu na prijeoperacijska očekivanja bilo je slično kod svih bolesnika. Vidna oštrina bez korekcije bila je 0.9-1.0 kod 92% bolesnika i nisu bile potrebne dodatne korekcije na blizinu. Zabilježena kvaliteta vida na blizu kod bolesnika s multifokalnom intraokularnom lećom bila je usko povezana sa zadovoljstvom nakon operacije katarakte. Ova studija je pokazala izrazito zadovoljstvo bolesnika s multifokalnom intraokularnom lećom, te bi oni opet izabrali istu kod ponovne operacije katarakte. Potreba za nošenjem korekcije za daljinu i blizinu je smanjena
