Purpose: To assess long-term clinical results following bilateral Tecnis Symfony ZXR00 intraocular lens implantation with mini-monovision. Methods: The medical records of cataract patients who underwent bilateral implantation of ZXR00 with intended mini-monovision (target refraction of –0.3 diopters [D] in dominant eye and –0.6 D in nondominant eye) between April 2019 and March 2021 were assessed. Postoperative uncorrected distance visual acuity (UDVA), corrected distance VA (CDVA), uncorrected intermediate VA (UIVA), uncorrected near VA (UNVA), and rate of spectacle dependence for near distance were investigated at 3 months and 2 years after surgery. Results: This study included 61 patients (122 eyes) with average age of 61.8 ± 7.7 years. At 2 years postoperatively, binocular logarithm of the minimum angle of resolution UDVA, UIVA, UNVA, and CDVA were 0.086 ± 0.094, 0.056 ± 0.041, 0.140 ± 0.045, and 0.012 ± 0.024, respectively. The monocular manifest refraction spherical equivalent was –0.31 ± 0.38 in the dominant eye and –0.53 ± 0.47 in the nondominant eye at 3 months postoperatively, and –0.38 ± 0.43 in the dominant eye and –0.61 ± 0.54 in the nondominant eye at 2 years postoperatively. Eight out of 61 patients (13.1%) needed glasses 3 months after surgery, and nine out of 61 patients (14.8%) needed glasses 2 years after surgery. Conclusions The bilateral implantation of ZXR00s with mini-monovision allows for a good VA at wide range of distance from far to near, thereby resulting in high rate of spectacle independence. These results have held up well even after 2 years after surgery.

Purpose: To evaluate the performance of two intraocular lenses (IOLs). The new monofocal IOL using a higher-order aspheric optic (Tecnis Eyhance ICB00) was compared to a standard monofocal IOL (Tecnis monofocal ZCB00) of the identical platform and material.
Methods: The medical records of the patients who had undergone cataract surgery with implantation of either the ZCB00 or the ICB00 in the dominant eye from March 2020 to August 2020 and with available data from the 3-month visit were reviewed. Subjects with ocular comorbidities or corneal astigmatism greater than 1.00 diopters were excluded. The uncorrected near, intermediate, distance visual acuity and corrected distance visual acuity were the main outcome measures. Optical quality parameters measured using an optical quality analysis system, clinical records including age, sex, laterality, ocular dominance, and information related to refractory errors was also collected. Parameters related to the refractory errors were all uniformly based on the Barrett Universal II formula.
Results: Of the 197 recruited patients, 111 and 86 were implanted with the ICB00 and ZCB00, respectively. No statistically significant differences in baseline parameters were observed between the two groups. While no statistically significant differences in distance visual acuity or optical quality were found between the two groups, compared to the ZCB00 group, the ICB00 group showed significantly higher intermediate visual acuity (p < 0.001) and near visual acuity (p < 0.05) 3 months postoperatively.
Conclusions ICB00 provided superior intermediate vision and comparable distance performance and photic phenomena compared to a standard monofocal IOL.

Objective: To systematically review the effect of intrathecal baclofen pump insertion in children with cerebral palsy (CP) with respect to scoliosis. Methods: A systematic literature search was conducted in PubMed, Embase, Cochrane Library, and Google Scholar databases up to June 2022. The inclusion criteria were as follows: (1) studies with a quantitative study design; (2) studies with a study group of children with CP; (3) studies comparing scoliosis in children with and without an intrathecal baclofen pump; and (4) studies with Cobb’s angle as a parameter. Results: Of the 183 studies found, four studies, all of which were retrospective comparative studies, met the aforementioned inclusion criteria. All studies were homogeneous (I2=0%, p=0.53) and intrathecal baclofen pump insertion accelerated the progression of scoliosis (standard mean difference=0.27; 95% confidence interval=0.07–0.48). Conclusion Intrathecal baclofen pumps have been used to alleviate spasticity in children with CP, thus aiding their daily activities and movements. However, their advantages and disadvantages should be reviewed after sufficient time considering the pumps’ negative effect on the course of scoliosis.

Objective: To propose the utilization of virtual tooth models (VTMs) created by combining tooth root data from cone-beam computed tomography (CBCT) and crown data gathered through intraoral scanning to assess inter-root distance and angulation during orthodontic treatment when repeated radiographic monitoring becomes necessary. Methods: Patients with planned dental implant placement in edentulous areas during or after orthodontic treatment and who underwent intraoral and CBCT scans at the pretreatment and posttreatment stages were selected. Tooth models were fabricated by merging intraorally scanned crowns with the corresponding CBCT-scanned roots from the pretreatment. Tooth positions posttreatment was estimated by integrating models into posttreatment intraoral scans. Moreover, the actual positions were obtained from posttreatment CBCTs. Discrepancies in the estimated and actual tooth positions, including interradicular distances and inter-root angulations, were compared. Results: The minimum inter-radicular distance between two adjacent teeth demonstrated no significant difference between the estimated and actual tooth positions. The difference in inter-root angulation was not statistically significant. Most interradicular distances measured at each landmark revealed no significant differences between the estimated and actual tooth positions, except at the buccolingual midpoint of the cemento-enamel junction, where a slight discrepancy was observed. Conclusions The tooth position of VTMs demonstrated clinically acceptable accuracy compared to CBCT scans. Additionally, VTMs can benefit both clinicians and patients by enabling accurate assessment of the inter-radicular space for dental implant placement without repeated CBCT scans.

Since the first description of this disease in 1887, there are rare reports on osteochondrosis dissecans (OCD) found in the glenoid cavity by way of anthropological studies. During an excavation project for recovery of the remains of Korean War casualties, a skeletonized soldier was found inside a cave fort at the Arrowhead Ridge of the demilitarized zone (DMZ), South Korea. In our recovery and examination of a Korean War casualty in DMZ, we identified a possible OCD in the individual’s glenoid cavity of a right-sided scapula by radiological analysis and computed tomography reconstruction. This is a rare case of scapular OCD discovered in an archaeologically investigated skeleton.
