Abstract
PURPOSE: The aim of this study was to examine postoperative tilt and decentration after implantation of plate-haptic intraocular lenses (IOLs) after cataract surgery. METHODS: This was an observational retrospective study in which we analyzed the medical records of patients who underwent phacoemulsification with aspiration followed by the implantation of either a plate-haptic IOL (LS-313 MF15; Santen Pharmaceutical Co., Ltd., Osaka, Japan) or an open-loop IOL (SY60WF; Alcon Inc., Fort Worth, Texas, United States). We reviewed patient demographics, visual acuity, and manifest refraction prior to surgery, as well as at one day, one week, one month, and six months postoperatively. Anterior chamber depth, lens thickness, axial length, decentration, and tilt were measured using anterior segment optical coherence tomography. RESULTS: A total of 45 eyes from 24 patients were included in the study. The plate-haptic IOL group consisted of 23 eyes, with a mean age range of 75.0±7.8 years, while the open-loop IOL group comprised 22 eyes, with a mean age range of 75.3±6.9 years. Over the six-month period, the plate-haptic IOL group showed no significant changes in tilt or decentration. There were no differences in tilt or decentration between the groups at any observation point. In the plate-haptic IOL group, tilt one month after surgery showed a significant correlation with the preoperative tilt of the lens (p = 0.002). CONCLUSION: The plate-haptic IOL group showed no significant increase in decentration or tilt at six months postoperatively. Plate-haptic IOL provided strong stability as an IOL platform.
