“…7,12,16,[26][27][28] Eyes with cataract have decreased contrast sensitivity and increased higher-order aberration. 12 Applegate et al 16 reported that the area under the contrast sensitivity function decreases as the wavefront variances increase after radial keratotomy.…”

Aims To evaluate the relation between higher-order aberration of the eye and contrast sensitivity function in eyes with keratoconus. Methods In 22 eyes of 14 patients with keratoconus (age 30.578.4 years, means7SD) and 26 eyes of 13 normal controls (age 29.276.7 years), ocular higher-order wavefront aberration for a 6-mm pupil was measured with the Hartmann-Schack aberrometer (KR-9000 PW, Topcon). The root mean square (RMS) of third-and fourth-order Zernike coefficients was used to represent higher-order aberrations. The letter-contrast sensitivity was examined using the CSV-1000LV contrast chart (Vector Vision). Results In the keratoconus group, the letter-contrast sensitivity showed significant correlation with third-order (Spearman's correlation coefficient r ¼ À0.736, Po0.001) and fourth-order aberrations (r ¼ À0.464, Po0.05). There was borderline correlation between log MAR BSCVA and third-order (r ¼ 0.413, P ¼ 0.070) and fourth-order aberrations (r ¼ 0.394, P ¼ 0.086). In the normal group, the letter-contrast sensitivity had no significant correlation with third-order (r ¼ À0.170, P ¼ 0.411) and fourth-order aberrations (r ¼ À0.088, P ¼ 0.673), and log MAR best spectacle-corrected visual acuity (BSCVA) showed no correlation with third-order (r ¼ 0.063, P ¼ 0.762) and fourth-order aberrations (r ¼ À0.282, P ¼ 0.165). Conclusions In eyes with keratoconus, there is significant correlation between contrast sensitivity and ocular higher-order wavefront aberrations.

“…[7][8][9][10][11][12][13] Recent studies using wavefront analysis technology reported that higher-order aberrations (HOAs) significantly increase after refractive procedures such as radial keratotomy, 14 photorefractive keratectomy, 15 and laser in situ keratomileusis. 16 These increases are known to be related to the deterioration of visual function. [14][15][16] However, no reports have addressed the changes in ocular aberrations after scleral buckling surgery by search using Pub Med.…”

Design: Prospective observational comparative case series. Participants:The study included 67 eyes of 67 RD patients undergoing scleral buckling surgery, and the fellow normal eyes comprised the control group.Twenty-seven eyes were treated with segmental buckling procedure and 40 eyes received encircling buckling procedure alone. Methods:Hartmann-Shack wavefront analysis was performed at 2 weeks, 1 month, and 3 months postoperatively. Main Outcome Measures: Time course of changes in HOAs.Results: The scleral buckling surgery significantly increased HOAs at 2 weeks (p <

Ocular Higher-Order Aberrations and Contrast Sensitivity after Conventional Laser In Situ Keratomileusis
