Changes in Higher-Order Aberrations after Scleral Buckling Surgery for Rhegmatogenous Retinal Detachment

“…Pesudovs et al revealed that coma-and spherical-like aberrations for 6-mm pupils in patients with various types of spherical intraocular lenses (IOLs) were 0.37-0.51 and 0.36-0.60, respectively. 31 Oshika et al described that third-and fourth-order RMS in 7-mm pupils were 0.883 and 1.455 after photorefractive keratectomy, respectively, and those after laser in situ keratomileusis were 1.436 and 1.941, respectively. 23 The amount of HOAs after scleral buckling surgery was similar to that after cataract surgery and lower than that after excimer laser refractive surgery.…”

Change in corneal aberrations after cataract surgery with 2 types of aspherical intraocular lenses

“…Pesudovs et al 14 studied the effect of 2 types of spherical IOLs (PMMA and acrylic) and incision locations (corneal and scleral) on total wave aberrations, measured with a Hartmann-Shack wavefront sensor. Aberrations in 20 eyes (PMMA IOL, scleral incision), 21 eyes (acrylic IOL, scleral incision), and 16 eyes (acrylic IOL, corneal incision) were compared with those in an age-matched control group.…”

Effect of total higher-order aberrations on accommodation in pseudophakic eyes

“…However, aberrations in pseudophakic eyes are not solely composed of corneal aberrations but also those of other components including IOLs. [17][18][19][20][21] Thus, it would be more appropriate to use total ocular aberrations for the analysis. In addition, target size is an important factor in the accommodative response.…”
