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

Figure 3

Illustration of the coma aberrations and measurements of tilt and decentration in a Scheimpflug image of a typical patient from the open-globe-injury group. Horizontal tilt was 2.85° and horizontal decentration was 0.50 mm; vertical tilt was 1.5° and vertical decentration was 0.47 mm. Internal coma is a major source of ocular coma.
