Between September 1, 2006, and November 30, 2006, CMS fixation was successfully applied to 3 eyes of 2 patients where membrane optic capture was impossible. Informed consent for participation was obtained from both patients. Clinical data are summarized in Table 1, and preoperative data are summarized in Table 2. All the eyes had comprehensive preoperative and postoperative assessments, which included testing of uncorrected and best-corrected distance visual acuity, manifest refraction by autorefraction (model RK-F1; Canon USA,Inc, Lake Success, New York), detailed slitlamp examination and funduscopy, measurement of IOP by Goldmann applanation, anterior chamber depth and keratometry measurements using an optical path difference scanning system (OPD-Scan II ARK-10000; Nidek, Inc, Freemont, California) and a multidimensional diagnostic system (Orbscan IIz; Bausch & Lomb, Rochester, New York), and ultrasound biomicroscopy (Sonomed, Inc, New Hyde Park, New York). Careful attention was given to the evaluation of zonular support by noting the presence of phacodenesis or iridodonesis preoperatively. In the case of aphakia requiring CMS fixation of a new IOL to the capsular remnant, axial length measurements were obtained by IOLMaster v5 (Carl Zeiss Meditec, Inc, Dublin, California), and the IOL power was calculated using 4 formulas (Haigis, Holladay II, Hoffer Q, and SRK/T) targeted for plano. The highest IOL power closest to emmetropia was chosen.
