ABSTRACT
INTRODUCTION: We compared postoperative metamorphopsia and optical coherence tomography (OCT) findings between eyes that underwent internal limiting membrane (ILM) peeling and the inverted flap (IF) technique for macular hole (MH). METHODS: This retrospective analysis included 64 eyes of 64 patients with idiopathic MH whose MH was closed after initial surgery. Thirty-nine patients were treated with pars plana vitrectomy (PPV) with ILM peeling, and 25 patients were treated with PPV with the IF technique. Best corrected visual acuity (BCVA), severity of metamorphopsia, and OCT images were collected before and 3, 6, and 12 months postoperatively. Based on the OCT images, the status of the external limiting membrane (ELM) and ellipsoid zone and the presence of hyperreflective plugs were assessed. RESULTS: At baseline and 3, 6, and 12 months postoperatively, BCVA and severity of metamorphopsia were not significantly different between groups. The status of the ELM was significantly worse in the IF group than in the ILM peeling group at 3 and 6 months postoperatively. Significantly more hyperreflective plugs were observed in the IF group than in the ILM peeling group at 3 and 6 months postoperatively. Stepwise multiregression analysis revealed that hyperreflective plugs were significantly associated with the severity of metamorphopsia at 12 months postoperatively. DISCUSSION/CONCLUSION: The alterations on the OCT were fewer in the ILM peeling group than in the IF group, while no significant differences were observed in postoperative severity of metamorphopsia between groups. Metamorphopsia was worse in eyes with hyperreflective plugs.

PURPOSE: Plate-haptic rotationally asymmetric multifocal toric intraocular lenses (IOL) (Lentis Comfort Toric) occasionally rotate extensively after surgery. We conducted the current study to investigate the incidence of extensive misalignment of this IOL and its association with clinical parameters. STUDY DESIGN: Retrospective case series. SUBJECTS AND METHODS: Data were collected from patients who had undergone phacoemulsification and implantation of a plate-haptic multifocal toric IOL. RESULTS: Among 332 eyes, extensive misalignment of toric IOLs ≥ 45º occurred in 3.3% (11 eyes). The amount of misalignment in eyes with extensive misalignment was 81.6 ± 22.9º, while in those without extensive misalignment, it was 3.0 ± 2.7º. The eyes with extensive misalignment showed significantly greater axial length (p < 0.001), larger corneal diameter (p = 0.034), and flatter corneas (p = 0.044) than those without extensive misalignment. Repositioning surgery to correct toric IOL misorientation was conducted in 9 eyes between 7 and 28 days after cataract surgery. In 2 eyes, repositioning surgery was carried out twice. CONCLUSIONS: In majority of cases plate-haptic multifocal toric IOLs showed satisfactory rotational stability, but extensive misalignment ≥ 45º occurred in 3.3% of cases.
