Objective:
Two methods are available for intraocular lens (IOL) insertion when the lens capsule is unavailable, including suture and sutureless fixations in which the IOL haptics are fixed in the sclera. The IOL position and refractive error after both procedures were compared.
Methods:
Data were retrospectively extracted from patients who underwent IOL insertion at our institution by suture or sutureless fixation (suture fixation: 12 eyes and sutureless fixation: 15 eyes). The postoperative IOL tilt angle and decentration distance were automatically calculated. The difference between the postoperative refractive error and the preoperative expected refractive value was determined and statistically investigated.
Results:
IOL position, tilt, and decentration were not significantly different between the two groups, but the refractive difference was significantly lower in the sutureless fixation group (P = 0.035). No significant correlation was found between IOL position and refractive difference.
Conclusions:
Short-term results reveal that both the suture and sutureless fixation groups performed well, with no significant deviation in IOL tilt and decentration compared to previous reports. However, suture fixation was significantly more prone to refractive differences than sutureless fixation.
