ePub - Purpose
This study aimed to compare visual and refractive outcomes after toric intraocular lens (IOL) implantation and limbal relaxing incision (LRI) in eyes receiving extended-depth-of-focus (EDOF) IOLs.
Methods
Clinical outcomes were compared between 60 patients who underwent EDOF toric IOL implantation and 60 patients who underwent EDOF IOL implantation combined with LRI. A toric IOL was implanted when corneal astigmatism exceeded 1.0 diopters (D) (group 1), whereas LRI was performed when corneal astigmatism was 1.0 D or less (group 2). Corneal astigmatism, refractive astigmatism, refraction, uncorrected visual acuity, and corrected visual acuity (logMAR) were analyzed in each group before surgery and 3 months postoperatively.
Results
Corneal and total corneal astigmatism did not differ significantly between preoperative and postoperative measurements in group 1 (P>0.05). In group 2, postoperative corneal and total corneal astigmatism (0.60±0.13 and 0.61±0.28 D, respectively) were significantly lower than the corresponding preoperative values (0.81±0.36 and 1.25±0.32 D, respectively; P<0.05). Refractive astigmatism decreased significantly in both group 1 and group 2, from 2.05±0.64 and 1.18±0.41 D preoperatively to 0.56±0.32 and 0.62±0.26 D at 3 months postoperatively, respectively; however, the magnitude of reduction was significantly greater in group 1 than in group 2 (P<0.05). Postoperative refractive astigmatism did not differ significantly between the two groups (P>0.05). In both groups, uncorrected and corrected visual acuity improved significantly after surgery (P<0.05), with no significant between-group difference (P>0.05).
Conclusion
Combining an EDOF IOL with LRI may be effective for mild astigmatism, whereas selecting a toric EDOF IOL may better support visual improvement in patients with moderate to severe astigmatism.

Abstract
PDFePub
- Purpose
This retrospective study evaluated the clinical outcomes of combined phacoemulsification, implantation of 1 of 3 types of advanced intraocular lenses (IOLs) with multifocality, and pars plana vitrectomy with epiretinal membrane (ERM) peeling in patients with cataract and ERM. Outcomes were compared with those in age-matched controls who underwent phacoemulsification with the same IOL alone.
Methods
A total of 70 eyes were included: 35 eyes underwent combined surgery, and 35 served as controls. In each group, 15 eyes received an advanced monofocal IOL (Tecnis Eyhance ICB00), 15 received a hybrid diffractive extended-depth-of-focus (EDoF) IOL (Tecnis Symfony ZXR00), and five received a hybrid refractive EDoF IOL (Precizon Presbyopic NVA).
Results
All groups showed significant visual improvement by 6 months postoperatively. Eyes that received hybrid diffractive EDoF IOLs and underwent combined surgery showed significantly worse mean corrected distance visual acuity, uncorrected distance visual acuity, corrected intermediate visual acuity, and corrected near visual acuity at 3 months than control eyes, but these outcomes improved to levels comparable to those of control eyes by 6 months. Eyes that received hybrid refractive EDoF IOLs showed similar early delays; however, interpretation was limited by the small sample size.
Conclusion
Overall, combined surgery was safe and effective, although early visual recovery may be delayed in eyes receiving EDoF IOLs. These findings suggest that advanced monofocal and EDoF IOLs may be considered in selected patients with ERM; however, the results should be interpreted cautiously because of the retrospective design and limited sample size.
