Purpose: To assess the repeatability and comparability of corneal power and central corneal thickness (CCT) measurements obtained using Orbscan II (Bausch & Lomb), Pentacam (Oculus), and Galilei (Ziemer) tomographers.Design: Prospective, comparative study.Methods: setting: Departments of Ophthalmology, University of Auckland and Auckland District Health Board, Auckland, New Zealand. study population: Thirty eyes of 30 healthy participants. observations. CCT and corneal power measured using Orbscan II, Pentacam, and Galilei tomography. main outcome measures: Degree of agreement in and repeatability of CCT and corneal power measures.Results: Orbscan II measured significantly lower CCT compared with Pentacam (20 μm; P < .0005) and Galilei (18 μm; P (Read more...)

Partial Lamellar Sclerouvectomy of Ciliary Body Tumors in a Korean Population – Corrected Proof
Purpose: To describe the clinical characteristics of ciliary body tumors, surgical outcomes, and factors associated with poor visual outcome and metastasis.Design: Retrospective case series.Methods: Medical records of 27 patients with ciliary body tumors who underwent partial lamellar sclerouvectomy in a single-center setting (Seoul, South Korea) were reviewed. Surgical outcomes were reviewed, and clinical characteristics were analyzed with respect to visual prognosis and globe retention rate.Results: Tumors were diagnosed histopathologically as benign in 8 (30%) cases and as melanoma in 19 (70%) cases. Patients had a median age of 48 years. The median follow-up was 3.5 years (range, 0.5 to 6 (Read more...)

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...)
