A comparison of visual performance between a rigid PMMA and a foldable acrylic intraocular lens

Abstract

WOODS, WILLIAM WYKESincidence of PCO is confirmed, it appears more economical to implant the conventional rigid PMMA IOL using small-incision surgery.

Effect of cataract surgery incision location and intraocular lens type on ocular aberrations

“…36 Our results contradict this. Other studies [37][38][39] had contrast sensitivity results with PMMA and acrylic IOLs that are similar to our results. Afsar and coauthors 38 also found no difference in visual performance between subjects with normal phakic eyes and those with PMMA IOLs.…”

Visual acuity and contrast sensitivity comparison between Tecnis and AcrySof SA60AT intraocular lenses: A multicenter randomized study

“…However, the variability of the obtained differences confirm other studies indicating that each IOL produces a different MTF in the implanted eye, thus giving rise to differences in contrast sensitivity. 7,16,17 Apart from optic design, optic material and refraction index probably play a role in the amount of induced aberrations. 7 Thus, the differences we encountered in the contrast sensitivity demonstrated by our 2 groups of patients could be partially related to differences in IOL material and optic characteristics not related to aberration correction or could be due to local factors.…”

Contrast sensitivity after implantation of a spherical versus an aspherical intraocular lens in biaxial microincision cataract surgery

“…Other studies indicate that each IOL produces a different modulation transfer function (relationship between the contrast of an object and its image) when implanted in eyes, giving rise to differences in contrast sensitivity. [25][26][27] Furthermore, apart from the optic design, the underlying optic material and refraction index could play a role in the amount of induced aberration. 25 Centration of an aspherical IOL could also play an important role in the quality of vision.…”
