Increased risk of cataract surgery in patients with allergic disease: a population based cohort study

Using 2,631,015 participants from the 2009 National Health Insurance Service-Health Screening Cohort in Korea, we investigated the relationship between cataract and allergic disorders, including atopic dermatitis, allergic rhinitis, and asthma. In total, 447,883 individuals had at least one allergic disease. After adjusting for demographic factors, systemic and ocular disorders, socioeconomic status, and lifestyle causes, the allergic group had a higher risk of cataract formation than the non-allergic group. In the subgroup review of subjects with AD, men aged 50 years had a higher heart rate than women of the same age group. In conclusion, patients with allergic disorders had a greater risk of cataract surgery than their peers, and the combination of AD and AR placed them in the highest risk. The association was more prominent in male than female patients with AD age 50 years, particularly in male than female patients with AD aged 50 years.

Self-assessed visual function outcome in cataract surgery: minimum important difference of the Catquest-9SF questionnaire

Randomized patients who had completed the Catquest-9SF before surgery and three months after surgery were sent an anchor question on self-assessed change in visual function after cataract surgery, 14 days after the postoperative Catquest-9SF. The patients were divided by their preoperative Rasch scores on the preoperative and postoperative Catquest-9SF questionnaires, and the results were compared to their preoperative Rasch scores. Based on the anchor question, the two groups' MID range was estimated, and the anchor question based MID was then estimated in a scatter plot. Based on a MID of u2212 1. 07, a Cohen's effect size based on MID of u2212 1. 07 and a Cohen's effect size based on MID of u2212 1. 07 was determined by the group with a better preoperative visual function. Based on a MID of u2212 1. 46, the group with worse preoperative visual function had an anchor question based on a MID of u2212 1. 80 and a Cohen's effect size based on a MID of u2212 1. 46.

Meridional ocular magnification after cataract surgery with toric and non-toric intraocular lenses

Background In modern cataract surgery, ocular magnification and meridional ocular magnification have both been largely ignored. OOM and MOM were extracted from the pseudophakic eye model using 4 u00d7 4 matrix algebra for the corrected eye. Results P_IOLeq/P_IOLcyl b1b1 1. 79 dpt/1. 38 dpt/1. 03 dpt/1. 39 dpt/1. 39 dpt/1. 49 for Haigis, and 20. 73 dpt/1. 29 dpt/1. 59 dpt/1. 29 dpt/1. 39 dpt/1. 39 dpt/1. 37 b1 1. 09 t/1. 83 dpt/1. According to the table, scenario 2 was 0. 91 dpt, 0. 9 dpt, 0. 89 dpt, 0. 69 dpt, and 0. 89 dpt. respectively. For scenarios 1 and 3, 2. 39/2. 6 percent, 0. 40/0. 9 percent, and 1. 06/2. 6 percent for scenario 2 with HofferQ, Haigis, and Castrop formulae, with 0. 49/1. 23%, 0. 41/1. 25%, and 0. 40/0. 9 percent, respectively. Conclusion Matrix's pseudophakic eye's appearance allows for a quick and easy estimation of OOM and MOM of the pseudophakic eye after cataract surgery.

Cost-Effectiveness of Presbyopia Correction Among Seven Strategies of Bilateral Cataract Surgery Based on a Prospective Single-Blind Two-Center Trial in China

Introduction The aim of this research was to determine a way to determine the cost-effectiveness of presbyopia correction in various aspects of bilateral cataract surgery to provide healthcare policymakers with information about patient selection and surgical consultation. Methods The cost-effectiveness analysis, based on a prospective single-blind two-center clinical trial, included seven steps in bilateral cataract surgery: monofocal, monovision, diffractive bifocal, blended, refractive bifocal, trifocal, and extended focus strategies. According to the wiliness-to-pay threshold of one and two percent annual disposable income per capita in 2021 percent annual disposable income per capita in 2021, per 10% rising rates, the likelihood that the trifocal policy is cost-effective and cost-effective were 81. 7% and 93. 2%, respectively. Conclusions The cost-effectiveness analysis carried out by ACER and ICER according to an objective spectacle independence rate is a key device in determining highly cost-effective presbyopia-correcting strategies in cataract surgery for clinical and policy decisions.

Intravitreal dexamethasone implant versus anti-vascular endothelial growth factor therapy combined with cataract surgery in patients with diabetic macular oedema: a systematic review with meta-analysis

In patients with diabetic macular oedema, the aim is to compare the results of cataract surgery with either anti-Vascular Growth Factor therapy or dexamethasone injection. A secondary result was considered as a secondary result, with a mean change in best corrected visual acuity. In the anti-VEGF group, a significant reduction in macular thickness was demonstrated in the DEX group at 3 months, but mean CMT changes in the anti-VEGF group was non-significant. Conclusions In DMO patients, cataract surgery, and DEX may have improved anatomical outcomes compared to cataract surgery combined with anti-VEGF therapy.

Effects and Prognosis of Cataract Surgery in Patients with Retinitis Pigmentosa

Introduction Cataract extraction can help patients with retinitis pigmentosa's visual acuity, while laser removal can raise photoreceptor degeneration by light damage. In this research, we conducted a systematic review and meta-analysis to investigate the benefits and predictions of VA after cataract surgery in patients with RP. Patients with RP were compared to those with cataract surgery before and after cataract surgery of different durations of follow-up and different organizational characteristics of the preoperative macular ellipsoid zone. Conclusions Cataract surgery may have increased VA for patients with RP during long-term follow-up, but it is not indicated for patients with invisible preoperative macular EZ. However, further research is required to address the issue of increased light exposure to the degenerated retina in patients with RP with cataract surgery.

Global–local multi-stage temporal convolutional network for cataract surgery phase recognition

Background & Indexing Surgical video phase recognition is a key component of computer-based surgical methods for assessing surgical outcomes, aiding surgeons in standardizing procedures and increasing postsurgical assessment and indexing. However, the high similarity between the phases and temporal variations of cataract videos poses the biggest challenge for video phase recognition. Methods We introduce a global multi-stage temporal network in this paper to investigate the subtle differences between high similarity surgical phases and surgical videos' temporal variations. The first recognizes the pupil and surgical instruments regions in the frame separately, which then determines the video frames' fine-grained semantic attributes. The proposed multi-stage temporal convolutional network increases the surgical phase recognition success by recording longer time series features in dilated convolutional layers with different receptive fields.

Cataract surgery and IOP: a systematic review of randomised controlled trials

Cataract surgery has been shown to influence intra-ocular pressure in patients with glaucoma; however, the full extent of this effect is disputed, particularly in patients with open-angle glaucoma. This report is designed to determine the true effect of cataract surgery on IOP change in patients with OAG, focusing on results obtained from randomised controlled trials. Methods An systematic review was conducted, including six different RCTs that investigated the net effect of cataract surgery on IOP. The evaluation of adverse results of cataract surgery revealed a highly positive safety record. Conclusion Although the role of cataract surgery in the glaucoma treatment algorithm remains to be established, this report finds a consistent reduction in IOP following surgery and reduced dependence on glaucoma drugs. After phacoemulsification, a potential downgrade in drugs can also be considered in well-controlled glaucoma patients.

Alcohol use patterns and risk of incident cataract surgery: a large scale case–control study in Japan

To assess the possibility of incident cataract surgery in Japan adults who have changed alcohol use habits. This was a case-control study that looked at 14,861 patients with incident cataract surgery and 14,861 matched controls. Both men and women were at an elevated risk of incident cataract surgery with increased total lifetime drinking, with a dramatic rise in risk occurring at >90 drink-years for men and > 40 drink-years for women. Between alcohol intake and cataract, a positive dose-u2013response relationship was observed. Restricted drinking may help to minimize cataract formation.
