Abstract:
Objective To compare the stray-light effects caused by different parts of optic edge of 7 intraocular lens(IOL)edge designs.Methods Monochromatic laser beam was used to illuminate the upper edge and complex of three-piece and single-piece IOLs at several angles of incidence.Light images produced in the retinal plane were photographed with a digital camera.The differences in the light images were compared between three-piece and single-piece IOLs.Results There were differences in light images between 2 groups,which may be due to different shapes of edge design when the upper edge of IOL was illuminated.Three-piece IOL exhibited line images or dense patch,which differed with single-piece IOL when the complex of IOL was illuminated.Conclusion Both edge shape and irregular structure in three-piece IOL complex may be important factors for postoperative glare in pseudophakic patients.
