“…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. Thus, the increase in HOAs after scleral buckling surgery may be less important than other anatomical and functional factors with regard to visual function.…”

“…The RMS of third-and fourth-order Zernike components (Z 3 -3 to Z 3 3 , Z 4 -4 to Z 4 4 , respectively) were used to represent coma-and spherical-like aberrations, respectively. [20][21][22][23][24] …”

“…[15][16][17][18][19] Letter-contrast sensitivity was measured with CSV-1000LV chart (Vector Vision, Columbus, OH, USA). This instrument uses letter optotypes all of which were the same size and of low spatial frequency (2.4 cycle/1).…”

“…Although higher-order aberrations (HOAs) make a small contribution (r10%) to the overall wave aberration in the eye, 71 some authors have shown a large effect of degradation in the quality of the retinal image and affect visual acuity. 72 There are factors that may contribute to the change in aberrations, such as ageing, [73][74][75][76][77] accommodation, 78 photoreceptors, 73 pupil size, 71,[79][80][81][82] refractive surgery, 76,[83][84][85] and tear film. 86,87 Even though there are no studies evaluating the impact that these factors could have on HOAs in people with DM, these do have a thicker and more convex lens, [54][55][56] can develop premature cataracts, [9][10][11] and suffer a series of changes associated with lachrymal gland dysfunction and dry eye syndrome.…”
