Factors contributing to long-term refractive error after cataract surgery

Objectives: Following cataract surgery, it's to determine factors that could influence the direction and extent of long-term refractive error. Patients who underwent cataract phacoemulsification surgery between January 1 and December 31, 2018, were included in the study population. Patients who underwent cataract surgery and another procedure were refused. Spherical equivalent refraction was measured at 2 months and three years after surgery and compared to target refraction, which was found at 2 months and 3 years after surgery. Conclusions This review included 221 eyes of 122 patients. In 217 eyes at 3 years post-operatively, a refractive error within 1. 00 D was made in 217 eyes. Regardless of whether eyes were more clear or more hypermetropic than predicted, prediction error dropped significantly between 2 months and three years after surgery. ACD and ACD-to-AL ratios can influence cataract surgery and refractive results, which can be influenced by the ACD and ACD-to-AL ratio. Individual patients may be able to determine the right IOL selection based on the pre-operative findings.

Early intervention for perioperative hypertension in cataract surgery

Purpose: Although perioperative blood pressure monitoring is vital, particularly for high-risk patients, no new study has looked at early monitoring of perioperative blood pressure changes before cataract surgery. Conclusion Early monitoring and monitoring of blood pressure in cataract surgery could help prevent perioperative hypertension without additional drug use, which may be especially useful in the clinical setting.

Systemic and ocular associations in pediatric patients undergoing cataract surgery

Purpose Evaluation for systemic disease is a vital component of pediatric cataract treatment. Although there are studies establishing links in large cohorts of children with infantile cataracts that require surgical and ocular involvement, there are no reports detailing their effects in large cohorts of children undergoing cataract surgery. Methods Retrospective chart review of consecutive patients undergoing cataract surgery at a pediatric tertiary referral center during a 30-year period was conducted. In 66% bilateral and 55% unilateral cataract patients, an identifiable cause for cataract was found. About 22% of bilateral cataracts, hereditary cataract made up 22%. In 60/408 bilateral and 15/319 unilateral cataract patients, cataracts were the result of chemotherapy for cancer or other systemic conditions requiring steroids. unilateral cataracts had higher ocular connections than bilateral cataracts, primarily due to ocular trauma and persistent fetal vasculature. Many with no family history of juvenile cataract should be investigated for systemic correlations, and genetic testing may be helpful in select situations.

Use of ellipsoid zone width for predicting visual prognosis after cataract surgery in patients with retinitis pigmentosa

Objective Objectives: Objective Objective: Using spectral-domain optical coherence tomography, we can determine the visual prognosis of cataract surgery in patients with retinitis pigmentosa. Methods This retrospective review included patients with retinitis pigmentosa who underwent uncomplicated cataract surgery between December 2017 and June 2020. During follow-up, the best postoperative BCVA were collected, according to the Preoperative best-corrected visual acuity and the highest postoperative BCVA were also collected. With best cut-off values of 513, 608, and 515 bcm, respectively, under the receiver operating characteristic curve for the ability of the horizontal, vertical, and average EZ widths to distinguish eyes with and without postoperative BCVA 0. 3 was 0. 971, 0. 960, and 0. 963, respectively. Conclusions The EZ width measurement can help predict cataract surgery prognosis in patients with retinitis pigmentosa. Patients with a EZ width of less than 600 bcm can be expected with a good visual acuity prognosis.

Comparisons of outcomes and complications of immediate sequential bilateral cataract surgery and unilateral cataract surgery in a tertiary hospital in South Korea

We investigated the prevalence of immediate sequential cataract surgery and unilateral cataract surgery in a tertiary hospital in South Korea during the coronavirus disease 2019 pandemic and compared visual results between the two groups. The preoperative corrective distance visual acuity of the unilateral cataract surgery group was lower than the ISBCS group, but there was no difference between the two groups in postoperative CDVA. There were no differences in symptoms between the two groups, however, two patients in the ISBCS group complained of postoperative strabismus, although two patients in the ISBCS group complained of postoperative strabismus.

Ten-year outcomes of cataract surgery for glaucoma management in patients with primary angle-closure disease

Purpose To investigate the long-term effects of cataract surgery for glaucoma treatment in patients with primary angle-closure disease. Methods We reviewed the medical records of 87 eyes of 87 patients with PACD who underwent uncomplicated cataract surgery alone at the Kobe City Medical Center General Hospital. The relationship to glaucoma treatment, number of glaucoma eye drops, the need for additional glaucoma therapy, photographic field improvement, and shift to glaucoma were all determined during the follow-up period. Almost half of the patients on PACG required additional glaucoma therapy; of those patients, six underwent glaucoma surgery. The condition deteriorated to PACG in 1 patient with PAC, but there was no such change in any of the patients with PACS. Conclusions With PACD, we found that cataract surgery had a long-term effect on IOP reduction in eyes. Patients with PACD may require early intervention with cataract surgery, which may be more appropriate for glaucoma treatment.

Quality assessment and comparison of two- and three-dimensional YouTube videos as additional educational tools for cataract surgery: “METAVERSE”

Background: With 2Ds, you will be able to compare the content and quality of 3D YouTube videos as additional educational aids in phacoemulsification surgery. Methods This cross-sectional research included 2D and side-by-side 3D phacoemulsification videos discovered on YouTube, with a search for u201c phacoemulsification, u201d and u201c cataract. According to video power index, interaction index, and viewing rate, video popularity and interaction were estimated by video power index, questionnaire index, and viewing rate. More views, likes, dislikes, days since debut, video quality index, and viewing rate were all higher than 3Ds compared to 3Ds. In 3D videos, the video length and interaction index were significantly higher than in 2Ds. In ORs, 3D videos outperformed 2Ds, according to all video scoring systems. Conclusions: By improving depth perception, 3D YouTube videos as additional educational aids may help not only SOs but also ORs fully comprehend the breadth and depth of ocular surgery, particularly phacoemulsification.

Comparison between intravitreal ranibizumab injection and posterior subtenon triamcinolone acetonide injection at time of cataract surgery for prevention of progression of diabetic macular edema

Results After 1 month of operation, there was a statistical significant difference in the median of CMT between ranibizumab & control group and the ranibizumab and subordinate TA group. The difference between the subordinate TA and control groups was significant after three months. Conclusions Combined phacoemulsification with intravitreal injections of ranibizumab or subtony triamcinolone acetonide can reduce CMT in people with DME following cataract surgery.

Roles of Toric intraocular Lens implantation on visual acuity and astigmatism in glaucomatous eyes treated with iStent and cataract surgery

During iStent triple procedures, we compared the effectiveness of toric intraocular lenses in combined cataract and minimally invasive glaucoma surgery. Results Preoperatively, the logarithm of the minimum angle of resolution UCVAs and refractive astigmatism were similar between the two groups. According to Vector results, the postoperative centroid magnitude and confidence eclipses of refractive astigmatism were smaller in the toric group than in the non-toric group. Compared to 11% in the non-toric group, 78% of eyes in the toric group had 1. 0 D or less refractive astigmatism. Conclusion When combined cataract and iStent surgery is performed in glaucomatous eyes with corneal astigmatism, using toric IOLs provides the most predictable results for improved visual outcomes.
