Higher order aberrations in keratoconus .

INTRODUCTION: Keratoconus is a progressive disorder of the cornea that causes thinning (Sedaghat et al. in Sci Rep 11(1):11971, 2021), ectasia, and irregular astigmatism, resulting in poor visual acuity that cannot be corrected with standard sphero-cylindrical spectacle lenses. One feature distinguishing keratoconic corneas is ocular aberrations, manifesting up to five or six times the amount of higher-order aberrations than a normal, healthy eye. These aberrations can cause visual disturbances even at the very early stages of the disease. METHODS: In the past, a diagnosis was derived from clinical symptoms, but technological advances have revealed multiple pre-clinical features, allowing for the differentiation between keratoconic and normal eyes at a much earlier stage. These include anterior and posterior corneal surface elevations, the corneal pachymetry profile, corneal epithelial patterns, wavefront aberration metrics, and corneal biomechanics (Sedaghat et al. in Sci Rep 11(1):11971, 2021).This review discusses the aberrations associated with keratoconus, how to measure them, and treatment methods to minimize their negative influence. CONCLUSIONS: Early diagnosis can lead to early treatment and may allow for arresting progression, thereby improving the long-term prognosis. With the acceleration of refractive surgery, it is important to identify patients with keratoconus, as they are usually contraindicated for refractive surgery.

Applications of topical immunomodulators enhance clinical signs of vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC): a meta-analysis.

PURPOSE: This meta-analysis aimed to review the safety and efficacy of topical cyclosporine A (CsA) and topical tacrolimus in allergic eye disease. METHODS: A systematic search identified thirteen studies and a total of 445 patients for inclusion, making this the largest meta-analysis published on the subject. The current review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS: Thirteen randomized control trials were included in the meta-analysis. Eleven studies used CsA as the treatment, and two used Tacrolimus. In total, 445 participants were included, of whom 76.6% were male. The mean age of participants across the included studies was 14 years. All studies reported clinical signs as evaluated by an examining clinician. Signs were usually assessed by anatomical region, with the most common regions being the conjunctiva and the cornea, and the most common signs assessed were hyperemia and papillae. Three studies accounted for more than 50% of the meta-analysis's weight. Effect size (d) ranged from - 2.37 to - 0.03, negative values favoring immunomodulators. Fixed Effect Meta-Analysis returned an SMD of - 0.81 (95% CI [- 0.98, - 0.65]). However, there was significant heterogeneity (I2 = 61%, Qw = 30.76) in the outcome measure (P = 0.0021); therefore, a random-effect meta-analysis was also completed in which the pooled SMD was - 0.98 (95% CI [- 1.26, - 0.69], τ2 = 0.16). CONCLUSIONS: This study affirms the current scientific community's stance that immunomodulators effectively treat clinical signs, including blepharitis, conjunctival hyperemia, edema, papillae, and corneal damage in severe ocular allergic disease.

[ADDITION OF LOW-CONCENTRATION ATROPINE IN COMBINATION OF DUAL-FOCUS CONTACT LENSES FOR MYOPIA CONTROL TREATMENT].

INTRODUCTION: The importance of myopia management lies in the desire to minimize the potential ocular risks that increase with high myopia. AIMS: To assess the decrease in myopia progression using topical low dose atropine combined with peripheral blur contact lenses (CL). METHODS: This retrospective review study included 25 children between the ages of 8.5 years to 14 years. The children all had a minimal increase in myopia of 0.75D during the year prior to treatment. The children were divided into two groups. The control group included 14 children who wore single-vision spectacles )SV) averaging 3.20±0.9D ranging from 1.5-5.3D. The study group included 11 children who wore dual-focus CL, with an average prescription of 3.4±0.7D ranging from 2.5 to 4.3D, for one year. At that point, when an additional myopia increase was observed, the children were additionally treated with topical 0.01% atropine for two years (CL+A0.01). RESULTS: There was an increase in myopia in the SV group of 1.12±0.52D, 1.08±0.56D and 0.96±0.53D in the first, second, and third years, respectively. The myopia increase in the CL+A0.01 group was 0.57±0.48D, 0.14±0.34D, and 0.17±0.29D in the first, second, and third years, respectively. CONCLUSIONS: Low-dose atropine combined with peripheral blur contact lenses was effective in decreasing myopia progression in this study. Additional, larger-scale studies are required in the future. DISCUSSION: This study found a significant decrease in myopia progression in the second and third years of treatment. The CL group showed less effectivity than the CL+A0.01 group.

[ARTIFICIAL INTELLIGENCE IN OPHTHALMOLOGY].

INTRODUCTION: Artificial intelligence (AI) was first introduced in 1956, and effectively represents the fourth industrial revolution in human history. Over time, this medium has evolved to be the preferred method of medical imagery interpretation. Today, the implementation of AI in the medical field as a whole, and the ophthalmological field in particular, is diverse and includes diagnose, follow-up and monitoring of the progression of ocular diseases. For example, AI algorithms can identify ectasia, and pre-clinical signs of keratoconus, using images and information computed from various corneal maps. Machine learning (ML) is a specific technique for implementing AI. It is defined as a series of automated methods that identify patterns and templates in data and leverage these to perform predictions on new data. This technology was first applied in the 1980s. Deep learning is an advanced form of ML inspired by and designed to imitate the human brain process, constructed of layers, each responsible for identifying patterns, thereby successfully modeling complex scenarios. The significant advantage of ML in medicine is in its' ability to monitor and follow patients with efficiency at a low cost. Deep learning is utilized to monitor ocular diseases such as diabetic retinopathy, age-related macular degeneration, glaucoma, cataract, and retinopathy of prematurity. These conditions, as well as others, require frequent follow-up in order to track changes over time. Though computer technology is important for identifying and grading various ocular diseases, it still necessitates additional clinical validation and does not entirely replace human diagnostic skill.

Wang-Landau sampling of lattice multiblock copolymers.

Synthetic multiblock copolymers are an interesting class of polymeric chains and have emerged as promising materials to mimic the function of complex biomolecules. In this work, we use Wang-Landau sampling to study sequences of multiblock (AnBn)m copolymers on the simple cubic lattice, where n represents the block length and m represents the number of blocks. We first compare to the thermodynamic and structural properties of four sequences previously studied in the continuum [W. Wang et al., J. Chem. Phys. 141, 244907 (2014)] to observe the differences that arise during the collapse process. We then focus on the structural transitions that occur at temperatures below the coil-to-globule transition in the lattice. Moreover, by studying additional sequences, we detail the relationship between the block length, number of blocks, and, thus, overall polymer length with respect to said structural transitions. Finally, we observe how the formation and shape of a ground state core of the more strongly interacting monomer type affect the procession of structural changes that occurs as temperature increases.

Carrier localization in perovskite nickelates from oxygen vacancies.

Point defects, such as oxygen vacancies, control the physical properties of complex oxides, relevant in active areas of research from superconductivity to resistive memory to catalysis. In most oxide semiconductors, electrons that are associated with oxygen vacancies occupy the conduction band, leading to an increase in the electrical conductivity. Here we demonstrate, in contrast, that in the correlated-electron perovskite rare-earth nickelates, RNiO3 (R is a rare-earth element such as Sm or Nd), electrons associated with oxygen vacancies strongly localize, leading to a dramatic decrease in the electrical conductivity by several orders of magnitude. This unusual behavior is found to stem from the combination of crystal field splitting and filling-controlled Mott-Hubbard electron-electron correlations in the Ni 3d orbitals. Furthermore, we show the distribution of oxygen vacancies in NdNiO3 can be controlled via an electric field, leading to analog resistance switching behavior. This study demonstrates the potential of nickelates as testbeds to better understand emergent physics in oxide heterostructures as well as candidate systems in the emerging fields of artificial intelligence.

[CONTACT LENS COMPLICATIONS].

INTRODUCTION: This article will review the complications of contact lenses (CL) according to the literature over the past few years including mechanical, inflammatory, allergic, toxic, metabolic, and infectious complications. There are CL complications that are not sight-threatening and there are severe complications that do threaten the sight. In general, any complication from CL that involves the cornea may endorse irreversible damage to sight. Most of the complications that involve the cornea are complications due to infectious backgrounds and are the most severe amongst CL wearers. The more continuous the CL wear is, the greater the danger to develop a complication. In the past it was assumed that switching from hydrogel CL to silicone hydrogel CL would reduce the incidence of CL complications, but this was not the case. From the point of view of wearing habits, the use of reusable CL (weekly or monthly) produced from more advanced raw materials did not reduce the percentage of complications. The complication may be due to incorrect CL compliance, incorrect use of the disinfecting solutions, incorrect compliance and cleaning of the CL. CL wearers aged between 15 to 19 years are the largest risk group to develop complications. Amongst younger aged wearers there is more precision due to parent supervision. The purchase of CL on-line has increased the percentage of complications because the patient purchasing the CL on-line does not attribute importance to the periodic examination by the professional eye therapist.

A systematic review on endovascular repair of isolated common iliac artery aneurysms and suggestions regarding diameter thresholds for intervention.

OBJECTIVE: Our aim was to systematically review results of endovascular aneurysm repair for isolated common iliac artery aneurysms (CIAA) regarding outcomes and to determine if changes should be made to current diameter threshold recommendations for intervention. METHODS: A comprehensive systematic review was performed according to the PRISMA guidelines. PubMed, Scopus, and the Cochrane Central databases were searched. RESULTS: Twenty-one studies were deemed eligible and provided data for 879 patients and 981 isolated CIAA treated with endovascular repair. The majority of the patients (90.8%) were males. The weighted mean age of the patients was 71.7 years (range, 37-91 years). The weighted mean diameter for the CIAA was 41. mm 1 (range, 15-110 mm) and for ruptured aneurysms 58.4 mm. The overall technical success rate was 97.6%. The perioperative mortality rate was 0.7%. Secondary patency rates were reported in only four studies and varied between 96.7% and 100%. The overall morbidity rate was 14%, ranging from 0% to 25%. Most of the studies did not report long-term or adequate follow-up data. Rupture of an isolated CIAA at <4 cm diameter was extremely low. CONCLUSIONS: Endovascular treatment of isolated CIAA is feasible and safe with a low mortality and excellent technical success rates. Consideration of increasing the diameter threshold for intervention of CIAA to 4 cm should be considered. Studies with longer follow-up and reliable long-term results are needed.

Effects of lattice constraints in coarse-grained protein models.

We compare and contrast folding behavior in several coarse-grained protein models, both on- and off-lattice, in an attempt to uncover the effect of lattice constraints in these kinds of models. Using modern, extended ensemble Monte Carlo methods-Wang-Landau sampling, multicanonical sampling, replica-exchange Wang-Landau sampling, and replica-exchange multicanonical sampling, we investigate the thermodynamic and structural behavior of the protein Crambin within the context of the hydrophobic-polar, hydrophobic-"neutral"-polar (H0P), and semi-flexible H0P model frameworks. We uncover the folding process in all cases; all models undergo, at least, the two major structural transitions observed in nature-the coil-globule collapse and the folding transition. As the complexity of the model increases, these two major transitions begin to split into multi-step processes, wherein the lattice coarse-graining has a significant impact on the details of these processes. The results show that the level of structural coarse-graining is coupled to the level of interaction coarse-graining.

Discovery of pre-therapy 2-deoxy-2-18F-fluoro-D-glucose positron emission tomography-based radiomics classifiers of survival outcome in non-small-cell lung cancer patients.

PURPOSE: The aim of this multi-center study was to discover and validate radiomics classifiers as image-derived biomarkers for risk stratification of non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Pre-therapy PET scans from a total of 358 Stage I-III NSCLC patients scheduled for radiotherapy/chemo-radiotherapy acquired between October 2008 and December 2013 were included in this seven-institution study. A semi-automatic threshold method was used to segment the primary tumors. Radiomics predictive classifiers were derived from a training set of 133 scans using TexLAB v2. Least absolute shrinkage and selection operator (LASSO) regression analysis was used for data dimension reduction and radiomics feature vector (FV) discovery. Multivariable analysis was performed to establish the relationship between FV, stage and overall survival (OS). Performance of the optimal FV was tested in an independent validation set of 204 patients, and a further independent set of 21 (TESTI) patients. RESULTS: Of 358 patients, 249 died within the follow-up period [median 22 (range 0-85) months]. From each primary tumor, 665 three-dimensional radiomics features from each of seven gray levels were extracted. The most predictive feature vector discovered (FVX) was independent of known prognostic factors, such as stage and tumor volume, and of interest to multi-center studies, invariant to the type of PET/CT manufacturer. Using the median cut-off, FVX predicted a 14-month survival difference in the validation cohort (N = 204, p = 0.00465; HR = 1.61, 95% CI 1.16-2.24). In the TESTI cohort, a smaller cohort that presented with unusually poor survival of stage I cancers, FVX correctly indicated a lack of survival difference (N = 21, p = 0.501). In contrast to the radiomics classifier, clinically routine PET variables including SUVmax, SUVmean and SUVpeak lacked any prognostic information. CONCLUSION: PET-based radiomics classifiers derived from routine pre-treatment imaging possess intrinsic prognostic information for risk stratification of NSCLC patients to radiotherapy/chemo-radiotherapy.

Elucidating thermal behavior, native contacts, and folding funnels of simple lattice proteins using replica exchange Wang-Landau sampling.

We studied the folding behavior of two coarse-grained, lattice models, the HP (hydrophobic-polar) model and the semi-flexible H0P model, whose 124 monomer long sequences were derived from the protein Ribonuclease A. Taking advantage of advanced parallel computing techniques, we applied replica exchange Wang-Landau sampling and calculated the density of states over the models entire energy ranges to high accuracy. We then determined both energetic and structural quantities in order to elucidate the folding behavior of each model completely. As a result of sufficiently long sequences and model complexity, yet computational accessibility, we were able to depict distinct free energy folding funnels for both models. In particular, we found that the HP model folds in a single-step process with a very highly degenerate native state and relatively flat low temperature folding funnel minimum. By contrast, the semi-flexible H0P model folds via a multi-step process and the native state is almost four orders of magnitude less degenerate than that for the HP model. In addition, for the H0P model, the bottom of the free energy folding funnel remains rough, even at low temperatures.

The role of chain-stiffness in lattice protein models: A replica-exchange Wang-Landau study.

Using Monte Carlo simulations, we investigate simple, physically motivated extensions to the hydrophobic-polar lattice protein model for the small (46 amino acid) protein Crambin. We use two-dimensional replica-exchange Wang-Landau sampling to study the effects of a bond angle stiffness parameter on the folding and uncover a new step in the collapse process for particular values of this stiffness parameter. A physical interpretation of the folding is developed by analysis of changes in structural quantities, and the free energy landscape is explored. For these special values of stiffness, we find non-degenerate ground states, a property that is consistent with behavior of real proteins, and we use these unique ground states to elucidate the formation of native contacts during the folding process. Through this analysis, we conclude that chain-stiffness is particularly influential in the low energy, low temperature regime of the folding process once the lattice protein has partially collapsed.

Tibioperoneal Trunk Aneurysm Resulting in Compartment Syndrome with Associated Aneurysms of the Popliteal and Dorsalis Pedis Arteries.

True aneurysms of the tibioperoneal trunk are rare. Given the scarcity of reports, the clinical presentation and treatment is not well defined. This is a case report of a 50-year-old male patient presenting with severe lower extremity swelling and compartment syndrome with neurological compromise secondary to a tibioperoneal trunk aneurysm. He was also noted to have discrete ipsilateral popliteal and dorsalis pedis artery aneurysms. Given the location and size of the aneurysm, the severe leg swelling, and venous hypertension, aneurysmorrhaphy or aneurysm sac excision with arterial reconstruction was prohibitively dangerous. Thus, following fasciotomies, a hybrid repair utilizing a saphenous vein superficial femoral to anterior tibial artery bypass along with coil embolization of the aneurysm sac was performed. The patient recovered full function of his leg and follow-up computed tomography angiogram demonstrated thrombosis and regression of the aneurysm sac with a patent bypass.

Molecular imaging of hypoxia in non-small-cell lung cancer.

Non-small-cell lung cancer (NSCLC) is the commonest cancer worldwide but survival remains poor with a high risk of relapse, particularly after nonsurgical treatment. Hypoxia is present in a variety of solid tumours, including NSCLC. It is associated with treatment resistance and a poor prognosis, although when recognised may be amenable to different treatment strategies. Thus, noninvasive assessment of intratumoral hypoxia could be used to stratify patients for modification of subsequent treatment to improve tumour control. Molecular imaging approaches targeting hypoxic cells have shown some early success in the clinical setting. This review evaluates the evidence for hypoxia imaging using PET in NSCLC and explores its potential clinical utility.

Primary esophageal cancer: heterogeneity as potential prognostic biomarker in patients treated with definitive chemotherapy and radiation therapy.

PURPOSE: To determine the association between tumor heterogeneity, morphologic tumor response, and overall survival in primary esophageal cancer treated with chemotherapy and radiation therapy (CRT). MATERIALS AND METHODS: After an institutional review board waiver was obtained, contrast material-enhanced computed tomographic (CT) studies in 36 patients with stage T2 or greater esophageal tumors who underwent contrast-enhanced CT before and after CRT between 2005 and 2008 were analyzed in terms of whole-tumor texture, with quantification of entropy, uniformity, mean gray-level intensity, kurtosis, standard deviation of the histogram, and skewness for fine to coarse textures (filters 1.0-2.5, respectively). The association between texture parameters and survival time was assessed by using Kaplan-Meier analysis and a Cox proportional hazards model. Survival models involving texture parameters and combinations of texture and morphologic response assessment were compared with morphologic assessment alone by means of receiver operating characteristic (ROC) analysis. RESULTS: Posttreatment medium entropy of less than 7.356 (median overall survival, 33.2 vs 11.7 months; P = .0002), coarse entropy of less than 7.116 (median overall survival, 33.2 vs 11.7 months; P = .0002), and medium uniformity of 0.007 or greater (median overall survival, 33.2 vs 11.7 months; P = .0002) were associated with improved survival time. These remained significant prognostic factors after adjustment for stage and age: entropy (filter 2.0: hazard ratio [HR] = 5.038, P = .0004; filter 2.5: HR = 5.038, P = .0004) and uniformity (HR = 0.199, P = .0004). Survival models that included a combination of pretreatment entropy and uniformity with maximal wall thickness assessment, respectively, performed better than morphologic assessment alone (area under the ROC curve, 0.767 vs 0.487 [P = .00005] and 0.802 vs 0.487 [P = .0003]). CONCLUSION: Posttreatment texture parameters are associated with survival time, and the combination of pretreatment texture parameters and maximal wall thickness performed better in survival models than morphologic tumor response alone.

Assessment of sarcopenia and changes in body composition after neoadjuvant chemotherapy and associations with clinical outcomes in oesophageal cancer.

OBJECTIVES: Sarcopenia and changes in body composition following neoadjuvant chemotherapy (NAC) may affect clinical outcome. We assessed the associations between CT body composition changes following NAC and outcomes in oesophageal cancer. METHODS: A total of 35 patients who received NAC followed by oesophagectomy, and underwent CT assessment pre- and post-NAC were included. Fat mass (FM), fat-free mass (FFM), subcutaneous fat to muscle ratio (FMR) and visceral to subcutaneous adipose tissue ratio (VA/SA) were derived from CT. Changes in FM, FFM, FMR, VA/SA and sarcopenia were correlated to chemotherapy dose reductions, postoperative complications, length of hospital stay (LOS), circumferential resection margin (CRM), pathological chemotherapy response, disease-free survival (DFS) and overall survival (OS). RESULTS: Nine (26 %) patients were sarcopenic before NAC and this increased to 15 (43 %) after NAC. Average weight loss was 3.7 % ± 6.4 (SD) in comparison to FM index (-1.2 ± 4.2), FFM index (-4.6 ± 6.8), FMR (-1.2 ± 24.3) and VA/SA (-62.3 ± 12.7). Changes in FM index (p = 0.022), FMR (p = 0.028), VA/SA (p = 0.024) and weight (p = 0.007) were significant univariable factors for CRM status. There was no significant association between changes in body composition and survival. CONCLUSIONS: Loss of FM, differential loss of VA/SA and skeletal muscle were associated with risk of CRM positivity. KEY POINTS: • Changes in CT body composition occur after neoadjuvant chemotherapy in oesophageal cancer. • Sarcopenia was more prevalent after neoadjuvant chemotherapy. • Fat mass, fat-free mass and weight decreased after neoadjuvant chemotherapy. • Changes in body composition were associated with CRM positivity. • Changes in body composition did not affect perioperative complications and survival.

First-in-man experience with the ReVive PV peripheral thrombectomy device for the revascularization of below-the-knee embolic occlusions.

PURPOSE: To report the initial use of a novel thrombectomy device for revascularization of below-the-knee thromboembolic occlusions encountered during proximal revascularization procedures. CASE REPORTS: The ReVive PV Peripheral Thrombectomy Device is a non-detachable, self-expanding stent-like device recently approved for peripheral thrombectomy. Four patients (3 women; mean age 68.8 years) undergoing proximal revascularization procedures experienced embolic occlusions of all 3 trifurcation vessels in 1 patient, the tibioperoneal trunk alone in 2 cases, and the peroneal artery alone in the last patient. In all cases, the involved arteries represented the primary or sole vessel(s) providing outflow to the lower extremity. In each case, the ReVive PV device was used to successfully extract the thrombus and restore flow to the distal extremity. No complications were encountered during any of the procedures. CONCLUSION: The ReVive PV peripheral thrombectomy device may facilitate the safe and efficient revascularization of distal arterial embolic occlusions.

Chronic mesenteric ischemia, renovascular hypertension and critical limb threatening ischemia treated with thoraco-visceral and lower extremity bypass: Major open surgical techniques will remain essential.

A 68-year-old female with extensive medical and surgical history, including open and endovascular procedures, presented with chronic limb-threatening ischemia, hypertension, and chronic mesenteric ischemia. A computed tomographic angiogram showed significant paravisceral aortic atherosclerosis involving the celiac, superior mesenteric, and renal arteries. She underwent an open descending aorta to superior mesenteric artery, left renal artery, and left common femoral artery bypass with a "trifurcated" ringed polytetrafluoroethylene graft. Nine months after surgery, she was progressing with significant improvement of her symptoms. Open surgical approaches in aortoiliac disease are reserved for patients with unfavorable anatomy or previous failed endovascular attempts. Detailed preoperative planning and careful patient selection are imperative for optimal outcomes.

Effective Decrease in Myopia Progression With Two Mechanisms of Management.

PURPOSE: To ascertain the effectiveness of 0.01% atropine treatment to inhibit myopia progression and the possible additive potency with peripheral defocus contact lenses over 3 years and the rebound effect 1 year after cessation of treatment. METHODS: This prospective study included 127 children aged 8 to 5 years, divided into three treatment groups: 0.01% atropine and single-vision spectacles (At+SV, n = 36), 0.01% atropine and peripheral defocus contact lens (At+PDCL, n = 30), and 0.01% atropine and dual-focus contact lens (At+DF, n = 25). A control group was prescribed single-vision spectacles (n = 36). Cycloplegic spherical equivalence refraction was measured every 6 months during 3 years of treatment and 1 year after cessation. RESULTS: Myopia progression decreased over 3 years of treatment, more during the second and third years than the first year, to a statistically significant degree in the atropine groups (P < .01): in the first, second, and third years, respectively, -0.42 ± 0.34, -0.19 ± 0.18, -0.22 ± 0.19 diopters (D) in the At+SV group, -0.26 ± 0.21, -0.14 ± 0.37, and -0.15 ± 0.31 D in the At+PDCL group, and -0.22 ± 0.15, -0.15 ± 0.22, and -0.11 ± 0.14 D in the At+DF group. Myopia progressed 1 year after cessation of treatment: -0.29 ± 0.28 D in the At+SV group, -0.13 ± 0.28 D in the At+PDCL group, and -0.09 ± 0.18 D in the At+DF group. After 3 years, there was no statistically significant difference in myopia progression between the At+SV and At+PDCL or At+DF groups (P < .05). CONCLUSIONS: Low-dose atropine has been substantiated in this cohort as an effective treatment to decelerate myopia progression over 3 years, more effective in the second and third years of treatment. The combination treatment did not exhibit a statistically significant advantage over monotherapy in this cohort. The At+DF group exhibited a statistically lower rebound effect than the At+SV group.

Treatment of Rapid Progression of Myopia: Topical Atropine 0.05% and MF60 Contact Lenses.

This retrospective study evaluates the effectiveness of combining 0.05% atropine with MF60 contact lenses in managing rapid myopia progression in children over one year. The study involved three groups: the treatment group (TG) with 15 children (53% male, average age 12.9 ± 1.04), the MF group (MF) with 12 children (50% male, average age 12.8 ± 0.8) using only MF60 lenses, and the control group (CG) with 14 children (43% male, average age 12.1 ± 0.76). Baseline myopia and axial length (AL) were similar across groups, with the TG, MF, and CG showing -4.02 ± 0.70 D, -4.18 ± 0.89 D, -3.86 ± 0.99 D, and 24.72 ± 0.73 mm, 24.98 ± 0.70 mm, 24.59 ± 1.02 mm, respectively. Prior to the study, all groups exhibited significant myopia and AL progression, with no previous myopia control management. The treatment involved daily 0.05% atropine instillation, the use of MF60 lenses and increased outdoor activity. Biannual cycloplegic refraction and slit lamp evaluations confirmed no adverse reactions. After one year, the TG showed a significant reduction in myopia and AL progression (-0.43 ± 0.46 D, p < 0.01; 0.22 ± 0.23 mm, p < 0.01), whereas the CG showed minimal change (-1.30 ± 0.43 D, p = 0.36; 0.65 ± 0.35 mm, p = 0.533). The MF group also exhibited a notable decrease (-0.74 ± 0.45 D, p < 0.01; 0.36 ± 0.23 mm). Increased outdoor activity during the treatment year did not significantly impact myopia control, suggesting its limited additional effect in this cohort. The study concludes that the combination of 0.05% atropine and peripheral defocus soft contact lenses effectively controls myopia progression in children.
