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 survey was to identify a way to assess presbyopia correction in a variety of approaches of bilateral cataract surgery in order to provide healthcare policymakers with guidelines for rationalizing resource allocation and surgeons in customizing patient care. Methods Seven strategies in bilateral cataract surgery were included in the cost-effectiveness report, based on a prospective single-blind two-center clinical trial, including monofocal, monovision, diffractive bifocal, blended, refractive bifocal, trifocal, and extended focus strategies. The chances that the trifocal plan is cost-effective and cost-effective were 81. 7% and 93. 2%, respectively, in 2021 per cent annual disposable income per capita. Conclusions This cost-effectiveness analysis by ACER and ICER, according to a realistic spectacle independence rate, is a useful device to determine highly cost-effective presbyopia-correcting techniques in cataract surgery for medical and policy decisions.

Comparison of the efficacy and safety of non-steroidal anti-inflammatory drugs and corticosteroid drugs for prevention of cystoid macular edema after cataract surgery

In non-diabetics and mixed populations, the NSAID and a combination of both medications significantly reduced the risk of developing CME than CS alone. When comparing bromfenac and nepafenac, Diclofenac was the most likely to reduce the chances of developing CME. Compared to betamethasone and fluorometholone, Dexamethasone was the most likely to reduce the chances of developing CME. Conclusion The NSAID combination with CS has significantly reduced the chance of developing CME postoperatively than the single drug. In preventing CME, Diclofenac was superior to bromfenac and nepafenac. In preventing CME, Dexamethasone was superior to betamethasone and fluorometholone.

Effects and Prognosis of Cataract Surgery in Patients with Retinitis Pigmentosa

Introduction Cataract extraction may improve visual acuity for patients with retinitis pigmentosa, while photosensitive degeneration may occur as a result of light damage. In this report, we conducted a systematic review and meta-analysis to determine the success and prediction of VA after cataract surgery in patients with RP. Methods We extracted results from the literature of existing studies using quality control processing. Patients with RP were compared to others who underwent cataract surgery before and after cataract surgery of different durations of follow-up and different levels of structural stability of the preoperative macular ellipsoid zone in patients with RP. Conclusions: Cataract surgery may extend the life of patients with RP during long-term follow-up, but it is not recommended for patients with ineffective preoperative macular EZ. However, further studies are required to solve the issue of increased light exposure to the degenerated retina in patients with RP with the cataract removed.

Efficacy and safety of intraoperative use of tropicamide 0.02%/phenylephrine0.31%/lidocaine1% intracameral combination during pediatric cataract surgery

Background The aim of this paper is to show the safety and efficacy of the intracameral use of tropicamide 0. 02%/lidocaine 1% in pediatric cataract surgery, a drug commonly used in adult patients but in children, but it is also off-label. Children from 0 to 4 years of age, with or without intraocular IOL implantation, in the absence of clinically relevant systemic conditions, history of ocular surgery, concurrent ocular medication, hypersensitivity to any of the ingredients, and post-traumatic cataracts, are among the patients undergoing cataract surgery. After the primary access to the anterior chamber during the surgery, patients were given the combination drug during the procedure. Results This review included 53 surgical procedures of 36 patients: 41 eyes were left aphakic, 41 eyes were left aphakic, while 12 eyes underwent primary IOL implantation. Conclusions The use of intracameral tropicamide 0. 02%/lidocaine 1% in pediatric cataract surgery is safe for obtaining a sufficient mydriasis without any necessary parameters changes during the procedure.

Refractive outcomes of toric intraocular lens in combined trabecular micro bypass stent implantation and cataract surgery in glaucomatous eyes

Purpose With a toric intraocular lens in glaucomatous eyes, it was determined that the effect of trabecular micro bypass stents on refractive outcomes. According to the control and 0. 11D in the iStent group, the mean refractive cylinder was 0. 26D, with 63% and 85% of eyes using a cylinder of 0 and 85%, respectively, with a cylinder of 0 and 92 percent 0. 5D respectively. In the control and 0. 22D in the iStent group, there was a difference between target and result spherical equivalent of 0. 26D, with all eyes within 0. 75D of target. In the control group and 0. 03 in the iStent group, LogMar uncorrected postoperative vision in eyes aimed for emmetropia was 0. 04 in the control and 0. 03 in the iStent group. In both groups, there was a statistically significant decrease in IOP and number of hypotensive drugs, with a decrease in IOP of 8. 6% in the control and 15. 7% in the iStent group.

Evaluation of IOL power calculation with the Kane formula for pediatric cataract surgery

Purpose In the pediatric population, the Kane formula for intraocular lens power estimation was not 100% correct. Methods The charts of pediatric patients who underwent cataract surgery with in-the-bag IOL implantation in one of two IOL devices in Toronto, Ontario, CanFada, were retrospectively reviewed. The reliability of IOL power estimation using the Kane formula was tested in comparison to the Barrett Universal II, Haigis, Hoffer Q, Holladay 1, and Sanders-Retzlaff-Kraff Theoretical formulas were evaluated. A significant difference was observed between the Hoffer Q and Haigis formulas. Conclusions This is the first review to look into the Kane formula in pediatric cataract surgery. Our findings place the Kane among the most notable IOL power calculation tools in this age group, providing an additional method for increasing IOL calculation in pediatric cataract surgery.

Optimizing intraocular lens power calculation using adjusted conventional keratometry for cataract surgery combined with Descemet membrane endothelial keratoplasty

Purpose: The aim of this study was to determine the effectiveness of intraocular lens power estimation using adjusted conventional keratometry techniques for eyes with Fuchu2019s dystrophy following cataract surgery combined with Descemet membrane endothelial keratoplasty. Methods The PPPA ratio in 50 eyes undergoing triple DMEK was determined, based on the PPPA ratio. Adjusted corneal power was calculated in every eye using adjusted K values: In every eye using adjusted K values; the IOLMaster's K values were converted to adjusted anterior corneal radius using the mean PPPA ratio. Conclusion IOL power calculation based on adjusted corneal power can be used to reduce the chance of a hyperopic shift after triple DMEK and provides a more accurate refractive result than traditional IOL power calculation using conventional K.

Geographic variation in cumulative incidence of private cataract surgery in Australia and its influencing factors: Findings from the 45 and Up Study

Purpose in a large Australian population, the objective is to investigate the geographic distribution of private cataract surgery and its association with remoteness, socioeconomic, and private health insurance coverage indexes. Methods The 45 and Up Study was a prospective population-based survey of 266,896 Australian adults living in New South Wales aged 45 years old and over. The incidence of PCS among 89 SA3s was estimated and compared to the baseline population. From the baseline interview, private health insurance coverage rates were determined. No significant relationship was found between socioeconomic deprivation and cumulative incidence of PCs. Conclusions and Conclusions The geographical variation in the overall prevalence of PCS calls for measures aimed at people living in remote areas to minimize the burden of cataract-related vision impairment.

Cataract surgery outcomes in eyes with previous radial keratotomy

Objectives/objectives This report reports the optical and refractive effects of cataract surgery in patients with previous radial keratomy. Objects/methods This is a retrospective case series of 100 eyes with former RKs who had undergone routine cataract surgery with a monofocal intraocular lens implant at Moorfields Eye Hospital, London, United Kingdom, between January 2004 and December 2018. The best-corrected visual acuity in eyes without copathology increased from 0. 30 to 0. 6, and with copathology, from 0. 56 to 0. 20 in eyes. Although the best-corrected visual acuity results compare to the UK national benchmarks, only a few eyes with previous RK reached the same degree of unaided distance visual acuity that allows spectacle independence. Surgeons should be aware of the increasing risk of wound dehiscence and plan surgery appropriately.

Returning to cataract surgery after a hiatus: a UK survey report

Objectives Cataract surgeons may take time away from operating as a result of skill development. There is a paucity of studies examining the experiences of returning cataract surgeons and how different family circumstances influence their return. Following the national elective surgical hiatus due to the Covid-19 pandemic, our aim was to investigate the subjective experiences of UK ophthalmologists who are returning to surgery simultaneously. Covid-19 was the most common cause of a surgical hiatus. Childcare was five times more likely to appear as a barrier to resource availability for females than males than males. In more than half of all surgeons following a halt of less than eight weeks, technical skills faded as a result of transient anxiety, rather than transient fear. Future returning cataract surgeons' future, which may help with patient care, according to our analysts. We believe there is ample opportunity for more specialized and targeted assistance for future returning cataract surgeons, thus improving patient care.
