“…In vitro studies show that laser-induced damage causes no significant decrease in optical resolution [6], [7], which explains the observation that visual acuity does not tend to be affected in vivo [6], [8]. However, these studies did suggest that laser damage may cause glare [5], [6], [9], which was also shown in other studies [10], [11].…”

This study optically determines whether the amount of light scatter due to laser-induced damage to the intraocular lens (IOL) is significant in relation to normal straylight values in the human eye. Two IOLs with laser-induced damage were extracted from two donor eyes. Each IOL had 15 pits and/or cracks. The surface area of each pit was measured using a microscope. For 6 pits per intraocular lens the point spread function (PSF) in terms of straylight was measured and the total straylight for all 15 pits was estimated. The damage in the IOLs was scored as mild/moderate. The total damaged surface areas, for a 3.5 mm pupil, in the two IOLs were 0.13% (0.0127 mm2) and 0.66% (0.064 mm2), respectively. The angular dependence of the straylight caused by the damage was similar to that of the normal PSF. The total average contribution to straylight was log(s) = −0.82 and −0.42, much less than the straylight value of the normal eye.The straylight due to normal levels of laser induced damage of the IOL is much lower than normal straylight values found clinically for the normal eye and may therefore be considered not significant.

“…According to the literature, there is no significant decrease in visual acuity due to laser damage [6]–[8], except when the IOL is severely damaged [10]. This is understandable when we consider the effect of scattering on the spatial contrast sensitivity function (CSF) (figure 9 in [13]).…”

“…A experiência técnica também foi apontada como fator causal de menor taxa de fossetas na lente intra-ocular (Nirankari e Richards, 1985;Flohr et al, 1985). Apesar de tudo, a maioria dos estudos que relataram dano à lente intra-ocular não observaram efeito clínico significante na função visual, mesmo nos casos de comprometimento do eixo visual (Boerner et al, 1984;Keates et al, 1984;.…”
