ABSTRACT
Management of surgically induced astigmatism is the major problem for surgeons implanting intraocular lenses. Besides corneal astigmatism, the fixation status of the intraocular lens(IOL) may contribute to postoperative astigmatism. This study was undertaken to analyze whether the variable factors such as fixation status, IOL type, and capsulotomy method affect tilting and decen tration of IOL. The tilting angle and decentration of the IOL were measured by image-processing technique using computerized Scheimpflug camera. The average tilting angle was 4.30 +/- 2.21 degree. The average decentration was 0.44 +/- 0.36mm from the corneal center. Based on these data, the astigmatic error induced by the tilting and/or decentration of the implanted IOL was calculated as within 0.1 diopter. Haptic fixation and designs were statistically significant for IOL posit ion but tilting and decentration were not significantly associated with capsulotomy method, agegroup, sex, and postoperative day.
