Short-Term Comparison of Surgical Results between One-Haptic and Two-Haptics Transscleral Fixation of Intraocular Lens

ABSTRACT

PURPOSE: To compare the short-term clinical outcomes of transscleral fixation intraocular lens (IOL) with two haptics or one haptic. METHODS: We retrospectively reviewed the medical records of 26 patients with transscleral fixation of IOL (11 with one-haptic fixation, 15 with two-haptic fixation) except in patients whose visual acuity is not expected to improve due to retinal problems or ocular trauma. We analyzed the manifest refraction, visual acuity, refractive error preoperatively and postoperatively, preoperative IOL decentration, operating time, and postoperative complications. RESULTS: When comparing the two groups preoperatively, the mean lens decentration in the one-haptic group was 2.73 ± 2.88 mm and 4.59 ± 2.18 mm in the two-haptics group. The decentration in the two-haptic group was greater than in the one-haptic group, but not significantly. Visual acuity and refractive power were not significantly different between the groups. The mean operation time (minutes) was 65.00 ± 22.69 and 93.66 ± 29.54 in the one-haptic and two-haptic groups, respectively. The operation time in the one-haptic group was significantly shorter than in the two-haptic group (p = 0.020). When comparing visual acuity preoperatively and postoperatively, both groups showed significant improvement (p < 0.01). However, refractive error and postoperative IOL decentration were similar between the groups. CONCLUSIONS: The short-term surgical results of transscleral fixation using the two surgical techniques were not different; one-haptic transscleral fixation was preferred due to shorter operation time and lower patient discomfort.
