ABSTRACT
BACKGROUND/PURPOSE:
This study aims to quantify and identify risk factors for intraocular lens (IOL) tilt and decentration early after surgery using Scheimpflug imaging.METHODS:
We prospectively included 268 eyes of 253 patients who underwent uneventful cataract surgery and one-piece IOL implantation using a superior or temporal approach. Scheimpflug imaging was used to evaluate the tilt and decentration of IOLs at 1 week, 1 month, and 3 months postoperatively. Differences in IOL tilt and decentration between the approaches were examined. Correlations of age and axial length with the magnitudes of IOL decentration and tilt were also examined.RESULTS:
In total, 139 right and 129 left eyes were included. IOL displacement averaged 150 µm upward and 150 µm to the nasal side of the pupil. Over 50% of the eyes were tilted upward and approximately 90% to the temporal side. The surgical approach was significantly associated with horizontal decentration in both eyes, but significantly associated with only vertical decentration in the right eye 1 week postoperatively. In the left eyes, IOLs were shifted to the nasal side in 57.1% and 36.8% of the eyes that received the temporal and the superior approach, respectively, compared with 75.8% and 50% in the right eyes. The differences were significant only at 1-week follow-up (p = 0.035 and p = 0.003, respectively). Age or axial length was not associated with IOL tilt or decentration in either eye.CONCLUSION:
Scheimpflug imaging can be used as a quantitative tool to evaluate IOL position. The incision site affected the IOL position, this finding was significant at 1 week postoperatively only.Palavras-chave
