Tilt, Decentration, and Internal Higher-Order Aberrations of Sutured Posterior-Chamber Intraocular Lenses in Patients with Open Globe Injuries

Figure 2

Internal higher-order aberrations (HOAs) and optical quality in the control and open-globe-injury groups. (a) and (b) show the internal HOAs in the two groups at pupil diameters of 4 mm (a) and 6 mm (b). At a premydriatic pupil size of 4 mm, most internal HOA values were significantly higher in the open-globe-injury group than in the controls. After mydriasis, only total HOAs, third-order HOAs, and coma differed significantly between the two groups. In (c), MTF at spatial frequencies of 15, 30, 45, 60, 90, and 105 cycles/degree were significantly lower in the open-globe-injury group than in the controls. (d) indicates significantly lower Strehl ratio in the open-globe-injury group than in the controls. .
