“…A sample-size weighted mean difference (MD) meta-analysis was performed for comparing final BCVAs, POM1 BCVA, post-operative ECC, and absolute SE error, as well as mean surgical durations between the Yamane and SSF treatment groups using the RevMan 5.4.1 software (Cochrane Collaboration, Copenhagen, Denmark) as previously described [ 7 , 43 ]. The RevMan 5.4.1 software was also used for meta-analysis of risk ratios (RRs) to compare complication rates, including CME and secondary surgery rates between Yamane and SSF techniques as previously described [ 11 , 43 , 44 ]. Due to the anticipated heterogeneity secondary to the variation in the protocols, follow-up durations, IOL types, and surgical technique, the random-effects model (DerSimonian and Laird method) was utilized.…”

Background: The purpose of the study is to compare the visual outcomes and complications of sutured scleral fixation (SSF), a traditional and conservative surgical approach, and the newer and faster Yamane technique for secondary intraocular lens placement. Methods: A literature search was performed on PubMed, Embase, and Scopus on studies published between 1 July 2017 to 29 September 2023. Outcomes analyzed included the final best corrected visual acuity (BCVA) between 3 and 12 months to assess the effectiveness of the procedure, post-operative month (POM) 1 BCVA to assess the speed of visual recovery, endothelial cell count (ECC), absolute refractive error, surgical duration, and complication rates. Additional subgroup analyses were performed based on surgeon experience with the technique. Single-surgeon studies had an average of 26 procedures performed, whereas multiple-surgeon studies averaged only 9 procedures performed; these were then used to delineate surgeon experience. A sample-size weighted mean difference (MD) meta-analysis was performed across all variables using RevMan 5.4.1; p < 0.05 was considered statistically significant. Results: Thirteen studies with 737 eyes were included: 406 eyes were included in the SSF group, and 331 eyes were included in the Yamane group. There was no significant difference in the final BCVA between groups in both the single-surgeon versus multiple-surgeon studies (MD = −0.01, 95% CI: [−0.06, 0.04], p = 0.73). In the single-surgeon studies, the BCVA at POM1 was significantly improved in the Yamane group compared to SSF (MD = −0.10, 95% CI: [−0.16, −0.04], p = 0.002). In the multiple-surgeon studies, there was no significant difference in BCVA at POM1 (MD = −0.06, 95% CI: [−0.16, 0.04], p = 0.23). The Yamane group had a shorter surgical duration than SSF in both single-surgeon and multiple-surgeon studies (MD = −24.68, 95% CI: [−35.90, −13.46], p < 0.0001). The ECC, refractive error, and complication rates did not significantly differ amongst all groups. Conclusions: The Yamane technique demonstrated similar long-term visual outcomes and complication rates to the traditional SSF. Visual recovery was significantly faster in the Yamane group in the single-surgeon studies. The operative times were shorter across all Yamane groups. Based on these findings, it is advisable to consider the Yamane technique as a viable, and perhaps preferable, option for patients requiring secondary IOL placement, alongside traditional SSF methods.

Intraocular Lenses for Cataract Surgery

What Is the Issue? A cataract is an opacity of the lens and is the leading cause of reversible visual impairment worldwide. There are no medical treatments for cataracts but surgical procedures that replace the lens with a synthetic lens (called an intraocular lens [IOL]) have shown to be effective for restoring vision. Premium lenses, including lenses to correct astigmatism (called toric lenses), are available but may not be covered by public or private health plans. Given that there is an increased cost associated with toric lenses, there is a need to evaluate their effectiveness compared to other available corrective options, including glasses. What Did We Do? To inform decisions about the appropriate use of astigmatism-correcting IOLs, CADTH sought to identify and summarize literature that evaluates the clinical effectiveness of toric lenses against other corrective options. An information specialist conducted a search of peer-reviewed and grey literature sources. One reviewer screened citations, and selected and critically appraised the included studies. What Did We Find? One systematic review (SR), 3 randomized controlled trials (RCTs), 1 prospective nonrandomized study, and 6 retrospective nonrandomized studies were identified that evaluated the clinical effectiveness of toric versus nontoric IOLs implanted during cataract surgery, including 1 with a pediatric focus. Toric IOLs may be better than nontoric IOLs for postoperative astigmatism, but this may be dependent on the measurement of astigmatism evaluated (e.g., corneal astigmatism, residual refractive astigmatism, subjective refraction astigmatism, autorefraction astigmatism, spherical equivalent astigmatism, cylinder astigmatism, surgically induced astigmatism). Toric IOLs may be better than nontoric IOLs for postoperative uncorrected visual acuity (VA), but it is unclear if this results in a clinically meaningful difference to the patient. None of the studies reported on spectacle independence. Patient-centred outcomes were seldomly reported across the studies, and rarely used validated tools, making it difficult to conclude if there were patient-centred outcome differences between toric and nontoric IOLs. Harms were reported across the studies through intraoperative complications, postoperative complications, and adverse events. Postoperative complications were statistically higher in the toric group in the SR, but there were not statistically significant differences in harms reported in the primary studies. What Does it Mean? It is difficult to draw conclusions across the studies and outcomes due to the variation in how outcomes were reported or because few studies report on these outcomes. A proposed minimum set of core outcomes for cataract surgery was published in 2015. The studies included in this report did not align with this minimum set of outcomes. For example, as VA is not synonymous with improved visual functioning for patients, evaluating patient-reported visual functioning with a patient-reported outcome measure (PROM) tool is part of the minimum set of core outcomes. Future research should incorporate core outcomes, including PROMs. Although toric IOLs statistically improved uncorrected VA, when compared to nontoric lenses, statistical significance does not imply a difference that is clinically meaningful to a patient.

“…The ICMR Survey 2017 indicates that the prevalence of cataracts has increased due to the growing older population brought on by improved healthcare and other factors [ 7 ]. The removal of the cataract and implantation of an intraocular lens (IOL) during cataract surgery allows for immediate vision recovery [ 8 ]. Despite the ease with which cataracts can be treated and the fact that cataract surgery is among the most cost-effective procedures, many isolated and underdeveloped regions of the developing world continue to see a high rate of cataract-related blindness, largely because of limited access to eye care [ 9 ].…”

The leading cause of blindness in the world is cataracts, which are dangerous and curable with proper eye care. Eye care service is thought to play significant role in prevention. Nonetheless, not much research has been done to gauge older persons' in rural India's level of cataract awareness and how it relates to their use of eye care services. Therefore, in order to prevent cataracts in the elderly, we described a self-instruction model for cataract knowledge and looked into the variations between pre- and post-test self-instruction models. Their demographic characteristics showed that the higher age group female had highest prevalence of cataracts. The study population's understanding of cataracts is incredibly low: only 2% of participants have adequate knowledge, 52% have somewhat adequate information, and 46% have inadequate knowledge. However, after completing the self-instructional module, 54% of participants felt they knew enough to prevent cataracts. The results of the study showed that the self-instructional module was very helpful in helping the senior population learn about cataract prevention. More interventional research with a larger sample size should be carried out to gain a better understanding of cataract prevention in older adults,.
