“…The present study shows that refractive stability is independent of the demographic parameters such as age and sex similar to the study by Mrugacz et al [ 11 ] where the findings were not statistically significant[ 11 ]. Comparing the AL as a variable, it was found that the stabilization of refraction in the 3 rd wk was achieved in 91% of the emmetropic, 77% of the myopic, and 46% of the hypermetropic patients, respectively.…”

BACKGROUND Knowledge about refractive stabilization and the accuracy of postoperative refractive error measurements are crucial for improved patient outcomes after phacoemulsification. Existing guidelines typically recommend waiting 4-6 wk before prescribing corrective lenses. Our research focused on identifying factors that influence refractive errors in the early stages of post-cataract surgery, thus contributing to the existing literature on this topic. AIM To investigate the time required for refraction stability after uneventful phacoemulsification surgery. METHODS We compared the variation and statistical significance of the difference in spherical, cylindrical components, and the spherical equivalent between the 1- and 6-wk follow-up period in a group of 257 eyes that underwent uneventful phacoemulsification with foldable intraocular lens implantation, all performed by a single experienced surgeon. The Wilcoxon-Signed Rank Test was utilized to assess the magnitude of the change and determine its statistical significance. The refractive stability was defined as the point at which the change in spherical equivalent was within ± 0.5 dioptres for two consecutive visits. RESULTS The average age of the patients was 64.9 ± 8.9 yr. The differences observed in both the visits in spherical power (0.1 ± 0.2), cylinder power (0.3 ± 0.4), and spherical equivalent (0.2 ± 0.2) were minimal and not statistically significant. The majority of eyes (93.4%) achieved refractive stability within 6 wk after the surgery. The cylindrical power differed between age groups at the 6th wk post-operative and the difference was statistically significant (P value 0.013). There were no significant differences in refractive stability when considering sex and axial length. CONCLUSION Phacoemulsification with foldable intraocular lens implantation results in no significant changes in refraction for the majority of cases during the 6-wk follow-up period. Therefore, a spectacle prescription can be given at the completion of 1 wk.

“…We found that there were no statistically significant differences among groups in terms of PE, suggesting that measurement errors caused by the optical evaluation devices could be considered negligible. Another reason for the accuracy of this measurement data is the absence of posterior staphyloma or myopic maculopathy in elongated eyeballs [ 24 ]. The optimized “A” constant and the Barrett Universal II formula were used to calculate the magnitude of the intended implantation IOLs [ 25 ].…”

Aim To evaluate the objective visual outcomes following implantation of extended depth of focus intraocular lens (EDOF IOL) in individuals with varying axial lengths (AL) and targeted refraction. Methods This retrospective study comprised age-matched eyes that underwent implantation of the EDOF IOL. Eyes were categorized based on AL into groups: control group with AL < 26 mm; high myopia group with AL ≥ 26 mm. Each group was then subdivided based on postoperative spherical equivalent (SE). Follow-up at three months included assessment of uncorrected visual acuity at different distances, contrast sensitivity (CS), refractive outcomes, and spectacle independence. Results Overall, this study included 100 eyes from 100 patients, comprising 50 males (50.00%) and 50 females (50.00%), with 20 eyes in each group. In the control group, the uncorrected distance visual acuity (UDVA) at 5 and 3 m (m) in the − 1.50 to -0.75 group was inferior to that of the − 0.75 to 0.00 group (P = 0.004). Conversely, the uncorrected near visual acuity (UNVA) at 33 cm in the − 1.50 to -0.75 group was superior to that of the − 0.75 to 0.00 group (P = 0.005). Within the high myopia group, the UDVA at 5 and 3 m in the − 2.25 to -1.50 group was worse than in the − 0.75 to 0.00 group (P = 0.009 and 0.008, respectively). However, the UNVA at 33 cm in the − 2.25 to -1.50 group was better than in the − 0.75 to 0.00 group (P = 0.020). No significant differences were observed among the groups for corrected distance visual acuity (CDVA) (P > 0.05). Additionally, in the high myopia group, the CS of the − 2.25 to -1.50 group was lower compared to that of the − 0.75 to 0.00 group (P = 0.017). Among high myopia patients, 90.00% with refraction ranging from − 1.50 to -0.75 reported achieving overall spectacle independence. Conclusions Implantation of extended depth of focus intraocular lenses (IOLs) yields satisfactory visual and refractive outcomes in eyes with axial myopia. Among high myopia patients, a refraction ranging from − 1.50 to -0.75 diopters achieves superior visual quality compared to other postoperative myopic diopters.

“…Epidemiological investigations have highlighted a significantly elevated risk of cataracts among patients with Diabetes, compared to the general populace [4,5]. Most research on diabetes-induced cataracts has focused on metabolic mechanisms [6,7], but often falls short in ruling out potential confounding factors, such as lifestyle elements and genetic predispositions [6]. The extent of genetic linkage between T1D and cataracts, and whether this linkage reflects a causal relationship, remains unclear.…”

BackgroundThe well-documented epidemiological link between type 1 diabetes and cataract is recognized. Yet, the question of a shared genetic foundation for these conditions, and the potential implication of a causal connection, is still an area of uncertainty.MethodsWe utilized a two-sample Mendelian randomization approach to extract and analyze four GWAS datasets from public databases, aiming to elucidate the causal relationship between Type 1 Diabetes and cataracts. Our study design incorporated multiple Mendelian randomization methods to assess the influence of Type 1 Diabetes genetic risk on the susceptibility to cataracts, and employed the MR-PRESSO global test for the evaluation of horizontal heterogeneity among the results.ResultsMendelian Randomization analysis has indicated a statistically significant association between Type 1 Diabetes and an increased risk of cataract development. All applied Mendelian Randomization methods pointed to a positive causal estimate, suggesting that Type 1 Diabetes contributes to an elevated risk of cataracts.ConclusionThis study supports the hypothesis of a causal relationship between Type 1 Diabetes and cataracts. Despite some heterogeneity, all outcomes are positively aligned, and leave-one-out analysis confirms the robustness of these findings. This research is significant for understanding the process of cataract prevention and treatment in patients with Type 1 Diabetes.
