- Purpose
This report presents a case of diffuse lamellar keratitis (DLK) after femtosecond laser-assisted small incision lenticule extraction (SMILE). The case was presumably associated with meibomian gland dysfunction (MGD).
Case
summary: A 25-year-old male patient underwent SMILE surgery. Preoperative examination revealed MGD in both eyes. Despite vigorous cleaning of the eyelid margin and irrigation of the ocular surface, meibomian gland secretion floating on the ocular surface was observed after the lenticule extraction in the right eye. At 2 days postoperatively, stage I DLK was detected. After aggressive topical steroid treatment, the DLK completely resolved without any sequalae.
Conclusion
DLK can occur in association with MGD. Attention should be paid when performing SMILE in eyes with MGD.

Abstract
PDFePub
- 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.

Abstract
- Purpose
This study reports a case of a large incisional tear caused by abrupt Bell’s phenomenon during pocket irrigation in femtosecond laser-assisted small incision lenticule extraction (SMILE).
Case
summary: A 28-year-old male patient underwent SMILE surgery. During pocket irrigation of the right eye, Bell’s phenomenon suddenly occurred, resulting in a large inferior arcuate extension of the incision that reached the inferior cap margin. After confirming wound integrity and the absence of additional tissue damage, a bandage contact lens was applied. On postoperative day 7, the incision was self-sealed with intact wound integrity. Three months postoperatively, uncorrected distance visual acuity was 20/20 in both eyes. The right cornea remained stable, although a faint residual scar was observed at the site of the incisional tear.
Conclusion
Abrupt eye movements during pocket irrigation in SMILE can cause large incisional tears. Surgeons should exercise heightened vigilance during irrigation, particularly in anxious or uncooperative patients, to prevent such complications.

Abstract
- 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.
