Background: Cataract-related vision impairment is clearly associated with depressive symptoms in old age. This study aimed to evaluate the effect of cataract surgery on depression among elderly Iranian patients. Methods: In this case–control study, a total of 113 elderly patients with and without cataract who were admitted to Buali-Sina Hospital in Sari, Mazandaran, Iran were evaluated. Ophthalmological examinations were first performed at the beginning of the study and then four months later; demographic and clinical characteristics were obtained for all patients. Additionally, depression was assessed using the Hospital Anxiety and Depression Scale (HADS) for all patients during the study period. Results: A statistically significant difference was found between the mean depression score in patients without cataract (3.28), patients with cataract surgery (3.74), and patients without cataract surgery (5.60) (P = 0.024). On the other hand, there was no statistically significant differences between the mean depression score in patients with cataract surgery and patients without cataract (P = 0.582). However, a statistically significant difference was observed between the mean depression score after cataract surgery in men (1.70) and women (4.94) (P < 0.001). Visual function improved in all bilateral cataract patients who had surgery in one eye. Also, the results of this study showed that in all unilateral cataract patients who had eye surgery, visual function in the left and right eyes improved. Conclusion: We conclude that depression is more prevalent in patients with cataract compared to those without cataract. In addition, cataract surgery seems to be associated with reduced depression and better visual acuity in elderly patients with cataract.

Objective. This study aimed to analyze the distribution of lens thickness (LT) and its associations in age-related cataract patients based on swept-source optical coherence tomography (SS-OCT). Methods. This cross-sectional study included 59,726 Chinese age-related cataract patients. Only right-eye data were included in the study. Repeated measures of ocular parameters were performed using an IOL Master 700 device. The distributions of ocular biometric data including anterior chamber depth (ACD), LT, axial length (AL), central corneal thickness (CCT), white-to-white (WTW), and mean keratometry (MK) and their associations with age were assessed. The anterior segment (AS) was measured as the sum of CCT, ACD, and LT, while the vitreous chamber depth (VCD) was calculated as the difference between AL and AS. The values of LT : AL, AS : AL, and VCD : AL in different AL groups and their changes are the main outcome measures used to observe the proportion of the anterior and posterior segments of the eye. Results. Biometric data were available for 59,726 individuals. The mean age was 68.81 years (range = 40–100); 40.62% were male and 59.38% were female. Mean anterior chamber depth (ACD) was 3.02 ± 0.44 mm, mean LT was 4.51 ± 0.44 mm, mean axial length (AL) was 23.89 ± 1.92 mm, mean central corneal thickness (CCT) was 0.53 ± 0.03 mm, mean white-to-white (WTW) was 11.64 ± 0.44 mm, and mean keratometry (MK) was 44.27 ± 1.65 diopter. Female patients had shorter AL, shallower ACD, smaller CCT and WTW, decreased LT, and steeper corneas ( p  < 0.005). ACD revealed the strongest negative correlation ( p  ≤ 0.001, r = –0.682) with LT. Age ( p  ≤ 0.001, r = 0.348) showed a moderate positive correlation, whereas MK ( p  < 0.05, r = 0.011), CCT ( p  ≤ 0.001, r = 0.041) had a weak positive correlation and WTW ( p  ≤ 0.001, r = –0.034) had a weak negative correlation with LT. A nonlinear correlation was found between LT and AL. LT increased with age in both males and females. LT changed variably in eyes with AL less than 27 mm, LT decreased as AL increased, then LT gradually increased as AL increased in extremely long and extra-long eyes ( p  ≤ 0.001). LT : AL and AS : AL decreased as AL increased, VCD : AL gradually increased as AL increased in highly myopic eyes, and VCD : AL increased by about 0.01 for every 1 mm increase in AL. Conclusions. Among Chinese age-related cataract patients, we found LT to have the strongest relation with ACD. The lens was thicker in elderly patients and women. The correlation between LT and AL is not a simple negative correlation; with the increase of age, LT decreases first and then increases. The proportion of VCD is constantly rising with the elongation of AL.

Background. The purpose was the choice of the type of tunnel incision on the basis of mathematical calculations in cataract patients with a previous anterior radial keratotomy. Materials and methods. During the calculations, the formula for the chord length of a circle was used: L = 2R · sin(α/2), where R is the radius of the cornea, α is the angle (in degrees) between the two corneal incisions. The chord length was measured on the limbus (upper edge of the tunnel incision) and 2 mm from the limbus (lower edge of the tunnel incision). The chord 2 mm from the limbus is more important because the distance between kerato­tomy incisions at this site is smaller. From 0.4 to 1.0 mm must be added to the width of the knife blade, depending on the type of postoperative corneal healing, which will be the key to crossing the incisions. Results. The most common knives are those 2.2 mm long with a tunnel length of 2 mm. Therefore, we perform calculations based on this knife in patients with 8 and 12 keratotomy incisions and a corneal diameter of 12 mm vertically and 11 mm horizontally. In patients with 8 keratotomy incisions, a 2.2 mm knife can be used for a corneal tunnel incision, and in patients with 16 incisions, it is impossible to use a corneal tunnel. Conclusions. In cataract patients who have previously undergone anterior radial keratotomy, a special approach is needed to the choice of tunnel incision. The choice of access depends on the diameter of the cornea, the number of keratotomy incisions and the width of the knife and is calculated using the formula for the chord length of a circle.

The purpose of this work is to examine the structure of the anterior lens epithelial cells (aLECs) of presenile idiopathic cortical cataract to investigate the possible structural reasons for its development. The anterior lens capsules (aLCs: basement membrane and associated lens epithelial cells) were obtained from routine uneventful cataract surgery of 5 presenile cataract patients (16 and 41 years old women and 29, 39, and 45 years old men). None of the patients had family history of cataract, medication, or trauma and they were otherwise healthy. In addition, the patients did not have any other abnormal features in the ocular status except cataract. The aLCs were prepared for scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The most prominent abnormal features observed by SEM for all 5 studied presenile cataract patients were the changes of the aLECs structure with the dents, the selective concavity of some LECs, at their apical side centrally toward the nucleus. In addition, TEM showed the thinning of the lens epithelium with the segmentally concave cells and the compressed and elongated nuclei. Abnormal and distinguishable structural features were observed in the anterior lens epithelium aLECs in all 5 patients with presenile cataract. Disturbed structure of aLECs, regularly present in presenile cataract type is shown that might be associated with water accumulation in the presenile idiopathic cortical cataract lens.

Purpose To compare visual acuity, defocus curve and visual quality of life performances of a new hybrid refractive-diffractive intraocular lens (IOL) and a trifocal diffractive IOL. Methods Patients who underwent cataract surgery with bilateral implantation of ZFR00V or TFNT00 IOLs were enrolled in this study. The main outcomes were defined as uncorrected distant, intermediate and near visual acuities (UDVA, UIVA and UNVA, respectively), defocus curve and VF-14 questionnaire aimed for visual performance. Results Fifty patients, of whom 30 had bilateral ZFR00V implantation, were enrolled in the study. Patients with ZFR00V had significantly better UIVA than patients with TFNT00 (0.05 ± 0.03 vs. 0.07 ± 0.04 logMAR, P = 0.02). Defocus curve showed significantly higher visual acuity in intermediate range for ZFR00V IOL between −1.00 and −1.50 dioptres (all P < 0.05). All patients had good visual performance with mean VF-14 scores above 3 points with no significant difference between two IOL models. Spectacle independence was 100% for both distant and near vision in both group of patients. Conclusion Bilateral implantation of ZFR00V in cataract patients shows better intermediate visual acuity scores and similar daily visual performance when compared with trifocal TFNT00 IOL.

Cataracts are the second most common cause of blindness in the world at 33%. The incidence of cataracts is 0.1% of the total population, so the number of new cataract cases in Indonesia is estimated at 250,000 per year. This study aims to compare the visual acuity of post cataract surgery patients with Small Incision Cataract Surgery and Phacoemulsification techniques at Sanjiwani Hospital, Gianyar. This study was a retrospective cohort at Ophthalmologist’s Outpatient Departement of Sanjiwani Hospital, Gianyar, Bali. The sample of this study was 60 patients with 84 eyes with senile cataract. The surgical techniques performed were Small Incision Cataract Surgery (53.6%) and Phacoemulsification (46.4%). After that, an Uncorrected Visual Acuity (UCVA) examination was carried out on day 1 and day 42. The result were cataract patients at Sanjiwani Hospital, Gianyar aged 60-65 years who were male. Comparison of visual acuity after Small Incision Cataract Surgery and Phacoemulsification had the same results. On day 1 and day 42, there was no different uncorrected visual acuity result between Small Incision Cataract Surgery and Phacoemulsification statistically.

To gain insight into the aetiology of posterior subcapsular congenital cataract from the perspective of transcriptional changes, we conducted an mRNA sequencing analysis of the lenses in posterior subcapsular congenital cataract patients and in normal children. There were 1,533 differentially expressed genes from 19,072 genes in the lens epithelial cells of the posterior subcapsular congenital cataract patients compared to in the normal controls at a cut-off criteria of |log2 fold change| of >1 and a p-value of <0.05, including 847 downregulated genes and 686 upregulated genes. To further narrow down the DEGs, we utilised the stricter criteria of |log2 fold change| of >1 and an FDR value of <0.05, and we identified 551 DEGs, including 97 upregulated genes and 454 downregulated genes. This study also identified 1,263 differentially expressed genes of the 18,755 genes in lens cortex and nuclear fibres, including 646 downregulated genes and 617 upregulated genes. The downregulated genes in epithelial cells were significantly enriched in the structural constituent of lenses, lens development and lens fibre cell differentiation. After filtering the DEGs using the databases iSyTE and Cat-Map, several high-priority candidate genes related to posterior subcapsular congenital cataract such as GRIFIN, HTRA1 and DAPL1 were identified. The findings of our study may provide a deeper understanding of the mechanisms of posterior subcapsular congenital cataract and help in the prevention and treatment of this disease.
