WHICH PRESBYOPIA CORRECTION METHOD PROVIDES THE BEST INTERMEDIATE VISION
We have compared the intermediate vision obtained by five different presbyopia correction methods: lens exchange and implantation of Acri.LISA bifocal intraocular lens, lens exchange and implantation of ReSTOR +3 bifocal intraocular lens, lens exchange and implantation of ReSTOR +2,5 in the dominant eye and ReSTOR +3 in the non-dominant eye bifocal intraocular lenses, lens exchange and implantation of Finevision trifocal intraocular lens, and excimer laser vision correction leaving in the non-dominant eye a myopia of -1,5 diopters.
The intermediate vision was measured by an specially designed logarithmic chart. We divided intermediate vision into two groups: near-intermediate (at 65 cm, more or less the distance of the screen on a computer) and far-intermediate (at 95 cm, more of less the distance of a person who is at the other side of your table).
Laser monovision achieved the best intermediate vision (logMAR 0,13 for near-intermediate and 0,1 for far-intermediate), followed by Finevision trifocal (logMAR 0,16 for near-intermediate and 0,13 for far-intermediate). The three bifocal intraocular lenses provided very similar near-intermediate vision (0,28-0,29- and 0,28 respectively) and the combination of ReStor +2,5/+3 was slightly better than the others for far-intermediate vision (0,22 vs 0,26 both the other bifocal).
