Comparison of toric intraocular lenses and limbal relaxing incision in extended-depth-of-focus intraocular lens implantation: Jiyoung Emily Lee, Eun Chul Kim; Received March 30, 2026 Accepted August 14, 2026 Published online September 23, 2026; DOI: https://doi.org/10.63375/icrs.26.003 [Epub ahead of print]

Abstract PDF 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.

Presbyopia-correcting intraocular lens options in myopic eyes undergoing cataract surgery: Sang Beom Han; Insights Cataract Refract Surg 2026;11(1):1-8. Published online February 26, 2026; DOI: https://doi.org/10.63375/icrs.25.016

Abstract PDF ePub: With ongoing advancements in surgical techniques and intraocular lens (IOLs) technologies, cataract surgery is increasingly recognized as a form of refractive procedure aimed at enhancing overall visual performance rather than being viewed solely as lens extraction. In parallel with this shift, a growing number of aging individuals with myopia are actively seeking spectacle independence following cataract surgery. The selection of IOLs for presbyopia correction in patients with myopia presents distinct clinical and refractive challenges, necessitating careful preoperative evaluation and individualized surgical planning. In this review, the author summarizes current evidence regarding the use of various IOLs, including monofocal, enhanced monofocal, extended depth-of-focus, and multifocal IOLs, for presbyopia correction in myopic patients and discusses key considerations involved in selecting the most appropriate IOL for this specific population.

Selection of an optimal intraocular lens according to the stage of epiretinal membrane: Sang Beom Han; Insights Cataract Refract Surg 2025;10(1):7-12. Published online February 28, 2025; DOI: https://doi.org/10.63375/icrs.25.003

Abstract PDF ePub

Epiretinal membrane (ERM), one of the most common retinal diseases, can cause various degrees of visual disturbance, reduced contrast sensitivity, and metamorphopsia. ERM is not infrequently encountered during preoperative evaluations for cataract surgery, and selecting an appropriate intraocular lens (IOL) according to the location and stage of ERM is necessary in order to improve visual outcomes and patients’ satisfaction. This review summarizes the application of various IOLs—such as multifocal, extended depth of focus, and enhanced monofocal IOLs—in eyes with ERM, and discusses the selection of an appropriate IOL.
