Optical Quality Comparison of Conventional and Hole-Visian Implantable Collamer Lens at Different Degrees of Decentering – Corrected Proof
Purpose: To compare the optical quality of implantable Collamer lens (ICL) with and without central hole (Hole ICL and conventional ICL) at different degrees of decentering.Design: Experimental laboratory investigation.Methods: Wavefront aberrations of the −3, −6, and −12 diopter (D) V4b and −3, −6, and −12 D V4c ICLs were measured in 3 conditions—centered and decentered 0.3 and 0.6 mm—at 3-mm and 4.5-mm pupils. The root mean square of total higher order aberrations, trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration were evaluated. In addition, point spread function and simulated retinal images of ICLs were calculated from the wavefront aberrations for each ICL and all conditions of decentering (Read more...)
