Purpose: To investigate the effect of the postoperative spherical equivalent (SE) and astigmatism on the uncorrected near/distance visual acuity (UNVA/UDVA) in monofocal intraocular lens (IOL)-implanted pseudophakic eyes. Methods: Of the eyes that underwent successful cataract surgery and monofocal IOL implantation from January 2020 to September 2021 by a single surgeon, eyes with postoperative astigmatism ≤ 1.5 diopters (D) and -0.75 D ≤ SE < +0.25 D were included. Eyes implanted with a toric IOL or with a best corrected visual acuity under 20/25 were excluded. This was a cross-sectional study, and the correlation of SE/astigmatism and UNVA/UDVA at 1 month postoperatively was analyzed retrospectively. The eyes were divided into mini-myopia (-0.75 D ≤ SE < -0.25 D) and emmetropia (-0.25 D ≤ SE < 0.25 D) groups according to the SE. Results: This study included 118 eyes (86 patients). The UNVA was significantly better in the mini-myopia group than in the emmetropia group (p = 0.009), without a significant difference in UDVA (p = 0.412). Dividing the range into 0.5 D units according to the degree of astigmatism, no significant difference was observed in UNVA/UDVA between the mini-myopia and emmetropia groups in eyes with astigmatism ≤ 1.0 D. However, the mini-myopia group had a significantly better UNVA (p = 0.03), without a significant difference in UDVA (p = 0.879) in eyes with astigmatism > 1.0 D or ≤ 1.5 D. Conclusions In non-toric monofocal IOL-implanted pseudophakic eyes with postoperative residual astigmatism of ≤ 1.5 D, especially in eyes with astigmatism > 1.0 D and ≤ 1.5 D, the mini-myopia group had a significantly better UNVA compared to the emmetropia group, without a significant difference in UDVA.

Traumatic rupture of the superior oblique muscle is rare. We report a case of a 54-year-old man injured by the metal hook of a hanger, resulting in a rupture of the superior oblique muscle tendon. He complained of torsional diplopia when in the primary position. The distal margin of the superior oblique muscle was reattached to sclera 5 and 9 mm apart from the medial insertion of the superior rectus muscle. One week after the operation, torsional diplopia disappeared. However, a 4-prism diopter ipsilateral hypertropia was observed. Three months later, hypertropia gradually increased to 20 prism dioptors and the second operation was done to correct vertical diplopia.

PURPOSE: This study evaluated the clinical outcomes of transcanalicular laser-assisted dacryocystorhinostomy (TCL-DCR) using a diode laser in patients with nasolacrimal duct obstruction (NLDO). METHODS: A total of 71 patients (76 eyes) who underwent TCL-DCR between May 2004 and April 2010 were analyzed. The functional and anatomic success rates were evaluated and the causes of failure were analyzed. RESULTS: The anatomic and functional success rates in primary TCL-DCR were 73.9% (51 of 69 eyes) and 62.3% (43 of 69), respectively. The causes of failure were membranous obstruction in 50.0% of the cases, granuloma formation in 38.9%, synechia formation in 5.6%, and canalicular stenosis in 5.6%. The anatomic and functional success rates were both 42.9% (3 of 7eyes) after TCL-DCR revision. CONCLUSIONS: The success rate of TCL-DCR is relatively comparable to that of conventional surgery. Additionally, the advantages of the procedure are its minimal invasiveness and convenience in an outpatient setting, suggesting that TCL-DCR may be an effective procedure for primary and secondary NLDO.

This survey's purpose was to understand the duties of the school dietitians' foodservice management and to identify the uses of preprocessed and processed food in Seoul Metropolitan area schools. The survey was distributed either via e-mail or in person to nutrition teachers and dietitians working at lementry, middle and high shools who participated in training sessions in Seoul, Gyeonggi and Incheon areas from December 2006 until June 2007. Four-hundred fifty-nine out of the total 760 schools that completed the surveys were analyzed. The following summarizes the main duties of school dietitians related to foodservice management: hygiene (100%), nutrition (99.8%), nutrition education (97.2%), cost (96.9%), and food production process control (96.3%). Preprocessed foods were ordered as the following: seafood (2.89)>poultry (2.78)>seeds (2.37). processed foods comprised the following order: pastes (4.94)>kimchi (4.91)>dressing materials (4.50). Based on these results, elementary schools must improve methods for developing effective study materials for nutrition education which are appropriate for each grade.

PURPOSE: To compare the long-term efficacy and safety of intravitreal triamcinolon with or without rescue laser therapy (intravitreal triamcinolone injection [IVTA] group), bevacizumab with or without rescue laser treatment (intravitreal bevacizumab injection [IVB] group), or a combination of both with or without rescue laser therapy (IVTA + IVB group), with standard care for patients with macular edema secondary to branch retinal vein occlusion (BRVO). METHODS: We reviewed the medical records of 151 patients treated with intravitreal injection with or without rescue laser for treatment of macular edema caused by BRVO, and who were followed up at 1, 3, 6, 12, and 24 months. During the observation period, rescue grid laser or repeated intravitreal injection with initial drug was performed if recurrence of macular edema was confirmed. Visual acuity, change in visual acuity, and intraocular pressure were compared in each phase. RESULTS: Totals of 16%, 5.6%, and 0% of participants in the three groups showed significant visual loss of more than three lines of the Snellen chart at last follow-up. The IVTA group was the least effective treatment modality, with statistical significance. The development rates of elevated intraocular pressure were similar among the groups. CONCLUSIONS: Although IVTA yielded effects similar to those of standard grid photocoagulation based on the Standard Care vs Corticosteroid for Retinal Vein Occlusion study, IVB or IVTA + IVB with or without rescue laser treatment resulted in improvement in visual acuity at 24 months after the start of treatment and was associated with few serious adverse side effects. Thus, these approaches could be useful for treating macular edema arising secondary to BRVO.

PURPOSE: To present the clinical outcomes of small incision lenticule extraction (SMILE) including visual quality analysis in Korean patients with myopia METHODS: The medical records of 228 eyes of 116 patients who underwent SMILE in HanGil Eye Hospital LASIK Center from May 2014 to Feb 2015 and were followed-up for at least 3 months was analyzed retrospectively. The patients were followed up at 1 day, 1 week, 1 month, and 3 months after the operation. Refractive value, visual acuity, intraocular pressure, and visual quality were measured at each visit RESULTS: Preoperatively, uncorrected distant visual acuity was 0.01 ± 0.02 in log MAR, spherical equivalent was -5.03 ± 1.72 diopters, intraocular pressure was 15.85 ± 2.85 mm Hg, and the objective scattering index (OSI) value was 0.68 ± 0.49. The postoperative uncorrected distant visual acuity was 0.13 ± 0.10, 0.05 ± 0.08, 0.04 ± 0.09, and 0.02 ± 0.04 and OSI was 2.16 ± 1.89, 1.25 ± 0.64, 1.14 ± 0.69, and 0.81 ± 0.36 at 1 day, 1 week, 1 month, and 3 months after the operation, respectively. The postoperative intraocular pressure was 12.55 ± 3.74 mm Hg, 13.03 ± 4.35 mm Hg, 11.65 ± 2.49 mm Hg at 1 week, 1 month, and 3 months after the operation. The efficacy of refractive surgery 3 months after the operation was 0.97 ± 0.11, the safety was 0.99 ± 0.10, and predictability was 99.56% and 100.00% at the range of ±0.5 diopters and ± 1.0 diopter, respectively. CONCLUSIONS: The SMILE operation showed comparable clinical outcomes with conventional refractive surgery in terms of efficacy, safety, and predictability. Intraocular pressure and visual quality normalized gradually throughout the 3-month postoperative period.

We report a case of corneal deposition of pigments from cosmetic contact lenses after intense pulsed-light (IPL) therapy. A 30-year-old female visited our outpatient clinic with ocular pain and epiphora in both eyes; these symptoms developed soon after she had undergone facial IPL treatment. She was wearing cosmetic contact lenses throughout the IPL procedure. At presentation, her uncorrected visual acuity was 2/20 in both eyes, and the slit-lamp examination revealed deposition of the color pigment of the cosmetic contact lens onto the corneal epithelium. We scraped the corneal epithelium along with the deposited pigments using a no. 15 blade; seven days after the procedure, the corneal epithelium had healed without any complications. This case highlights the importance of considering the possibility of ocular complications during IPL treatment, particularly in individuals using contact lenses. To prevent ocular damage, IPL procedures should be performed only after removing the lenses and applying eyeshields.
