This study aimed to elucidate the clinical characteristics of patients diagnosed with toxoplasmosis in Korea. We collected and analyzed the specific research data of 5,917 patients from the Health Insurance Review and Assessment (HIRA; 2007–2020) and 533 electronic medical records (EMRs; 2003–2021) of Korean patients. The HIRA data showed that toxoplasmosis is an endemic disease that occurs constantly in Korea, with a large proportion of patients complaining of ocular symptoms. Of the 533 patients for whom EMR data were available, 54.6% were diagnosed with toxoplasmosis; ocular toxoplasmosis (35.7%), congenital toxoplasmosis (4.7%), cerebral toxoplasmosis (4.1%), pulmonary toxoplasmosis (0.4%), and toxoplasma hepatitis (0.6%), in order of frequency. In ocular cases, 54.4% of the patients had diverse ocular pathologies. Toxoplasmosis in Korea is characterized by a high frequency of ocular symptoms, most patients are adults, and 51.8% of patients with seropositivity were positive for IgG, suggesting prior infection. This study highlights that patients with ocular symptoms are included in the major diagnosis group for acquired toxoplasmosis in Korea.

New Korean guidelines for the diagnosis and management of dry eye disease were developed based on literature reviews by the Korean Dry Eye Guideline Establishment Committee, a previous dry eye guideline by Korean Corneal Disease Study Group, a survey of Korean Dry Eye Society (KDES) members, and KDES consensus meetings. The new definition of dry eye was also proposed by KDES regular members. The new definition by the regular members of the KDES is as follows: “Dry eye is a disease of the ocular surface characterized by tear film abnormalities and ocular symptoms.” The combination of ocular symptoms and an unstable tear film (tear breakup time <7 seconds) was considered as essential components for the diagnosis of dry eye. Schirmer test and ocular surface staining were considered adjunctive diagnostic criteria. The treatment guidelines consisted of a simplified stepwise approach according to aqueous deficiency dominant, evaporation dominant, and altered tear distribution subtypes. New Korean guidelines can be used as a simple, valid, and accessible tool for the diagnosis and management of dry eye disease in clinical practice.

PURPOSE: To compare the new swept-source optical coherence tomography based IOL Master 700 to both the partial coherence interferometry based IOL Master 500 and ultrasound A-scan in terms of the ocular biometry and the prediction of postoperative refractive outcomes. METHODS: A total 67 eyes of 55 patients who received cataract surgery were included in our study. The axial length, anterior chamber depth, and keratometry were measured using IOL Master 700, IOL Master 500, and A-scan. The predictive errors, which are the differences between predictive refraction and post-operative refraction 1 month after surgery, were also compared. RESULTS: Axial length measurements were not successful in 5 eyes measured using IOL Master 700 and in 12 eyes measured using IOL Master 500. The mean absolute postoperative refraction predictive errors were 0.63 ± 0.50 diopters, 0.66 ± 0.51 diopters, and 0.62 ± 0.51 diopters for IOL Master 700, IOL Master 500, and A-scan, respectively, and these values exhibited no statistically significant differences. The mean axial lengths were 24.25 ± 2.41 mm, 24.24 ± 2.40 mm, and 24.22 ± 2.39 mm; the mean anterior chamber depths were 3.09 ± 0.39 mm, 3.17 ± 0.39 mm, and 3.15 ± 0.46 mm; and the mean keratometry values were 44.12 ± 1.82 diopters, 44.57 ± 2.10 diopters, and 43.98 ± 1.84 diopters for the IOL Master 700, IOL Master 500, and A-scan groups, respectively. None of these parameters showed statistically significant differences between the three groups. Regarding pair-wise comparison, there were significant differences between the IOL Master 700 and the other devices. CONCLUSIONS: The ocular biometric measurements measured using IOL Master 700, IOL Master 500, and A-scan showed no significant differences. However, IOL Master 700 demonstrated a superior ability to successfully take biometric measurements compared to IOL Master 500. Therefore, IOL Master 700 is capable of measuring ocular biometry for cataract surgery in clinical practice.

BACKGROUND: Transverse abdominis plane (TAP) block can be recommended as a multimodal method to reduce postoperative pain in laparoscopic abdominal surgery. However, it is unclear whether TAP block following local anesthetic infiltration is effective. We planned this study to evaluate the effectiveness of the latter technique in laparoscopic totally extraperitoneal hernia repair (TEP). METHODS: We randomly divided patients into two groups: the control group (n = 37) and TAP group (n = 37). Following the induction of general anesthesia, as a preemptive method, all of the patients were subjected to local anesthetic infiltration at the trocar sites, and the TAP group was subjected to ultrasound-guided bilateral TAP block with 30 ml of 0.375% ropivacaine in addition before TEP. Pain was assessed in the recovery room and post-surgery at 4, 8, and 24 h. Additionally, during the postoperative 24 h, the total injected dose of analgesics and incidence of nausea were recorded. RESULTS:: On arrival in the recovery room, the pain score of the TAP group (4.33 +/- 1.83) was found to be significantly lower than that of the control group (5.73 +/- 2.04). However, the pain score was not significantly different between the TAP group and control group at 4, 8, and 24 h post-surgery. The total amounts of analgesics used in the TAP group were significantly less than in the control group. No significant difference was found in the incidence of nausea between the two groups. CONCLUSIONS: TAP block following local infiltration had a clinical advantage only in the recovery room.

PURPOSE: To compare the clinical results after implantation of three one-piece aspheric lenses, Acrysof IQ SN60WF, Tecnis 1-piece ZCB00 and the newly developed IOL HOYA AF-1 NY-60. METHODS: In total 66 eyes, one of three one-piece aspheric lenses, Acrysof IQ SN60WF, TECNIS 1-piece ZCB00 or HOYA AF-1 NY-60 was implanted after cataract extraction. Best corrected visual acuity (BCVA) and uncorrected visual acuity (UCVA) were assessed at postoperative 3 months. Total spherical aberration, high order aberration and modulation transfer function of 5.0 mm pupil size zone were evaluated. RESULTS: There were no significant differences of UCVA, BCVA, the accuracy of postoperative refractive power and modulation transfer function among three groups. High order aberrations of the entire eye and internal optics showed almost no significant differences except some aberration values. CONCLUSIONS: The newly developed intraocular lens, HOYA AF-1 NY-60 showed almost equal clinical results in comparison with Acrysof IQ SN60WF and TECNIS 1-piece ZCB00.

PURPOSE: To evaluate the influence of pupil size on uncorrected visual acuity and spherical aberration of the TECNIS 1-piece intraocular lens (IOL). METHODS: In this study 61 eyes were implanted with a TECNIS 1-piece IOL. Pupil size was checked by standard pupil card with cobalt blue light postoperatively. Best corrected visual acuity (BCVA) and uncorrected visual acuity (UCVA) were assessed postoperatively. Total spherical aberration and high-order aberration for mesopic pupil size zone were measured. RESULTS: There were no significant differences of spherical equivalent, age, preoperative astigmatism, BCVA between two groups, but small pupil group revealed better UCVA (p = 0.02) and lower ocular aberration than large pupil group. CONCLUSIONS: After cataract surgery, pupil size greater than 5.0 mm increases total aberration. Thus, visual acuity with small pupil after aspheric TECNIS 1-piece IOL implantation show better clinical result on uncorrected visual acuity.
