Project description:Purpose. To compare pain scores between first-eye and second-eye cataract surgery and to determine the affecting factors. Methods. 106 first-eye and 53 second-eye cataract surgery patients (mean age: 67 ± 13 and 69 ± 10 years, resp.) were enrolled. The patients completed simplified State-Trait Anxiety Inventory and visual analog scale (VAS) for anxiety questionnaires before surgery, and VAS for pain and Wong-Baker Faces Pain Rating Scale questionnaires after surgery. Blood pressure (BP) and heart rate (HR) were recorded perioperatively. Results. A greater proportion of patients who underwent second-eye surgery reported intraoperative pain compared with first-eye surgery patients (85% versus 35%, P < 0.001). The pain scores were higher in second-eye surgery, while the VAS anxiety score was lower in second-eye surgery. Moreover, 31 patients reported greater pain during second-eye surgery than their first one, with higher pain scores than other 22 patients (P = 0.032 and 0.003, resp.). The VAS pain score of these 31 patients was positively correlated with the differences between the intraoperative and postoperative diastolic BP, mean arterial pressure, and HR. Conclusions. Cataract patients were likely to have more pain during second-eye surgery, which may be related to lower preoperative anxiety. Monitoring perioperative BP and HR may help to identify patients with intraoperative pain.

Project description:Purpose: To evaluate whether dry eye deteriorates after phacoemulsification cataract surgery, and to explore the influential factors. Methods: Studies published before February 2020 indexed on PubMed and the Cochrane Central Register of Controlled Trials were retrieved. A meta-analysis, including meta-regression, a sensitivity analysis, and a subgroup analysis, were performed. Results: Twenty studies with 2,247 eyes were included in the meta-analysis, dry eye-related parameters were investigated preoperatively and 1 month postoperatively. Patients with pre-existing meibomian gland dysfunction (MGD) had worsened subjective symptoms of dry eye (1.31, 95% confidence interval (CI) [0.66, 1.95], P < 0.0001), a reduced tear break-up time (BUT) (-2.27, 95% CI [-2.66, -1.88], P < 0.0001), and a worse corneal fluorescein staining (CFS) score (0.75, 95% CI [0.5, 1.0], P < 0.0001) after phacoemulsification cataract surgery, whereas in the general population, the subjective symptoms score and CFS remained unchanged and BUT decreased slightly after surgery. Patients without diabetes showed significantly reduced total tear secretion after phacoemulsification cataract surgery (-1.25, 95% CI [-1.62, -0.88], P < 0.0001). Conclusion: Dry eye generally remained unchanged 1 month after phacoemulsification cataract surgery. Notably, worsened symptoms and signs of dry eye were observed more frequently in patients with pre-existing MGD. Patients without diabetes were more susceptible to reduced tearing postoperatively.

Project description:ObjectivesTo investigate the impact of first eye and second eye cataract surgery on the level of physical activity undertaken by older adults with bilateral cataract.DesignProspective cohort study.SettingThree public ophthalmology clinics in Western Australia.ParticipantsFifty-five older adults with bilateral cataract aged 55+ years, awaiting first eye cataract surgery.Outcome measuresThe primary outcome measure was participation in moderate leisure-time physical activity. The secondary outcomes were participation in walking, gardening and vigorous leisure-time physical activity. Participants completed a researcher-administered questionnaire, containing the Active Australia Survey and visual tests before first eye cataract surgery, after first eye surgery and after second eye surgery. A Generalised Estimating Equation linear regression model was undertaken to analyse the change in moderate leisure-time physical activity participation before first eye surgery, after first eye surgery and after second eye surgery, after accounting for relevant confounders.ResultsParticipants spent significantly less time per week (20 min) on moderate leisure-time physical activity before first eye cataract surgery compared with after first eye surgery (p=0.04) after accounting for confounders. After second eye cataract surgery, participants spent significantly more time per week (32 min) on moderate physical activity compared with after first eye surgery (p=0.02). There were no significant changes in walking, gardening and vigorous physical activity throughout the cataract surgery process.ConclusionFirst and second eye cataract surgery each independently increased participation in moderate leisure-time physical activity. This provides a rationale for timely first and second eye cataract surgery for bilateral cataract patients, even when they have relatively good vision.

Project description:PurposeTo compare the subjective preoperative experiences of patients undergoing their first- or second-cataract surgeries.Patients and methodsConsecutive patients undergoing phacoemulsification were asked to complete postoperative questionnaires evaluating their subjective preoperative experiences, including their emotional state, decision-making process, and opinions on the admission and examination processes, medical interviews, and quality of service. The obtained data were compared between patients undergoing their first (group I)- or second (group II)-cataract surgeries.ResultsTwo hundred patients (group I, 124; group II, 76) were included in the evaluation. Presurgical anxiety was more prevalent in group I than in group II (55.7% vs 34.2%, P = 0.005). Fear was the major trigger for reconsidering the decision to undergo surgery, with 29% and 13.2% of patients in groups I and II, respectively, considering abandoning the operation (P = 0.016). The preoperative medical examination was reported to be sufficiently accurate by 66.1% and 80.3% of patients in groups I and II, respectively (P = 0.047), while 28.2% and 21% of patients in groups I and II, respectively, did not understand the information presented about possible complications of surgery (P = 0.039). Administration of eyedrops before surgery was uncomfortable for 71.4% and 68.4% of patients in groups I and II, respectively (P = 0.553), while 22.6% and 9.2% of patients in groups I and II, respectively, found repeated administration of drops to be highly uncomfortable (P = 0.026).ConclusionPatients experienced greater anxiety before their first-cataract surgery than before their second-cataract surgery. Moreover, many patients from both groups did not understand the medical information provided by doctors regarding the surgery and its possible complications. The most unpleasant stage of preparation for cataract surgery was repeated administration of eyedrops.Trial registrationThe study was registered on clinicaltrial.gov under the number NCT04327856.

Project description:ObjectiveTo compare fall incidence, and visual acuity and refractive status, before surgery and after first and second eye cataract surgery.Design, settingProspective observational study in eight tertiary referral ophthalmology clinics in public hospitals in Sydney, Melbourne, and Perth.ParticipantsPeople aged 65 years or more referred for bilateral age-related cataract surgery during 2013-16, followed for maximum of 24 months after study entry or until six months after second eye surgery, whichever was shorter.Main outcome measuresPrimary outcome: age- and sex-adjusted incidence of falls.Secondary outcomesvisual acuity and refractive error.ResultsThe mean age of the 409 included participants was 75.4 years (SD, 5.4 years); 220 were women (54%). Age- and sex-adjusted fall incidence prior to surgery was 1.17 (95% CI, 0.95-1.43) per year, 0.81 (95% CI, 0.63-1.04) per year after first eye surgery, and 0.41 (95% CI, 0.29-0.57) per year after second eye surgery. For the 118 participants who underwent second eye surgery and participated in all follow-up visits, age- and sex-adjusted incidence before (0.80 [95% CI, 0.55-1.15] falls per year) and after first eye surgery (0.81 [95% CI, 0.57-1.15] falls per year) was similar, but was lower after second eye surgery (0.32 [95% CI 0.21-0.50] falls per year). Mean habitual binocular visual acuity (logMAR) was 0.32 (SD, 0.21) before surgery, 0.15 (SD, 0.17) after first eye surgery, and 0.07 (SD, 0.15) after second eye surgery.ConclusionsFirst eye surgery substantially improves vision in older people with cataract, but second eye surgery is required to minimise fall incidence. Timely cataract surgery for both eyes not only optimises vision in older people with cataract, but also reduces their risk of injury from falls.

Project description:BackgroundOur purpose was to examine the value of the first postoperative day review after uneventful phacoemulsification cataract surgery.Methods291 patients who underwent uneventful phacoemulsification were randomized into two groups (ClinicalTrials.gov Identifier: NCT01247155): i) Next day review (NDR group, n = 146) and ii) No next day review (NNDR group, n = 145). The rate of complications, percentage of patients seeking non-scheduled medical consultation up to postoperative day 14, presence of any inflammation-related sign and best corrected visual acuity (BCVA) on postoperative day 28 were analyzed.ResultsIn the NDR group, 5.5% of patients developed a postoperative complication, whereas the respective rate was 6.2% in the NNDR group. The difference was not statistically significant (p = 0.791). The most frequent complications were: elevated intraocular pressure, allergy to postoperative treatment, corneal abrasion, punctuate epitheliopathy, iris prolapse and postoperative hyphema, whose rates did not differ between the two groups. The rate of patients seeking non-scheduled medical consultation up to postoperative day 14, presence of any inflammation-related sign, as well as BCVA on day 28 did not exhibit any significant differences between the study groups.ConclusionsFirst postoperative day review could be omitted in cases of uneventful cataract surgery.

Project description:BackgroundElective cataract surgery is the most commonly performed surgical procedure in developed countries. However, it is unclear whether cataract surgery on the second eye provides enough incremental benefit to be considered cost-effective. This study conducted a cost-effectiveness analysis of second-eye cataract surgery in the U.K.DesignA cost-effectiveness analysis.MethodsA decision-analytical model was developed to estimate the cost-effectiveness of second-eye cataract surgery, based on a comprehensive epidemiological and economic review to develop the parameters for the model. The model followed the clinical pathway of cohorts of patients receiving second-eye cataract surgery and included costs and health benefits associated with post-surgical complications.ResultsIn the model, second-eye surgery generated 0.68 additional quality-adjusted life years (QALY) with an incremental cost-effectiveness ratio of £1,964 per QALY gained. In sensitivity analyses, model results were most sensitive to changes in the health-related quality of life (HRQoL) gain associated with second-eye surgery, but otherwise robust to changes in parameter values. The probability that second-eye surgery is cost-effective at willingness to pay thresholds of £10,000 and £20,000 was 100%.ConclusionSecond-eye cataract surgery is generally cost-effective based on the best available data and under most assumptions. However, there are only a small number of clinical trials for second-eye cataract surgery, and these have not been conducted in recent years.

Project description:PurposeTo report the 3-month results of a randomized trial (Femtosecond Laser-Assisted Cataract Trial [FACT]) comparing femtosecond laser-assisted cataract surgery (FLACS) with standard phacoemulsification cataract surgery (PCS).DesignMulticenter, randomized controlled trial funded by the UK National Institute of Health Research (HTA 13/04/46/).ParticipantsSeven hundred eighty-five patients with age-related cataract.MethodsThis trial took place in 3 hospitals in the UK National Health Service (NHS). Randomization (1:1) was stratified by site, surgeon, and 1 or both eyes eligible using a secure web-based system. Postoperative assessments were masked to the allocated intervention. The primary outcome was unaided distance visual acuity (UDVA) in the study eye at 3 months. Secondary outcomes included corrected distance visual acuity, complications, and patient-reported outcomes measures. The noninferiority margin was 0.1 logarithm of the minimum angle of resolution (logMAR). ISRCTN.com registry, number ISRCTN77602616.Main outcome measuresWe enrolled 785 participants between May 2015 and September 2017 and randomly assigned 392 to FLACS and 393 to PCS. At 3 months postoperatively, mean UDVA difference between treatment arms was -0.01 logMAR (-0.05 to 0.03), and mean corrected distance visual acuity difference was -0.01 logMAR (95% confidence interval [CI], -0.05 to 0.02). Seventy-one percent of both FLACS and PCS cases were within ±0.5 diopters (D) of the refractive target, and 93% of FLACS and 92% of PCS cases were within ±1.0 D. There were 2 posterior capsule tears in the PCS arm and none in the FLACS arm. There were no significant differences between arms for any secondary outcome.ConclusionsFemtosecond laser-assisted cataract surgery is not inferior to conventional PCS surgery 3 months after surgery. Both methods are as good in terms of vision, patient-reported health, and safety outcomes at 3 months. Longer-term outcomes of the clinical effectiveness and cost-effectiveness are awaited.

Project description:ObjectiveTo introduce a novel technology currently under final development before regulatory approvals for the furtherment of cataract surgery, using the FemtoMatrix® laser system, and to demonstrate its safety and efficacy as compared to standard ultrasound phacoemulsification.MethodsThirty-three patients with bilateral cataracts were operated on with one eye undergoing PhotoEmulsification® treatment on the FemtoMatrix® device and the contralateral eye receiving the control procedure, i.e., standard ultrasound phacoemulsification treatment. The number of "zero-phaco" procedures (denoting that I/A alone was sufficient to aspirate the lens fragments and that no ultrasound energy was needed) was recorded and Effective Phaco Time (EPT) values were compared. The patient follow-up was 3 months.ResultsThirty-three eyes from a population with a mean cataract grade of 2.6 were treated on the FemtoMatrix®, of which 29 were "zero-phaco" (88%). All patients were operated on by a single surgeon who was a relative novice to the technology (63 patients treated prior to this study). Conversely, of the 33 fellow eyes who underwent standard ultrasound phacoemulsification, none were zero-phaco (0%) - all required varying degrees of ultrasound energy to make lens aspiration possible. The mean EPT was significantly lower in the PhotoEmulsification® laser group (0.2 ± 0.8 s) than in the phaco group (1.3 ± 1.2 s) (p < 0.0001). The safety profiles of the two procedures were comparable, with no device-related adverse events noted.ConclusionFemtoMatrix® is a promising femtosecond laser platform that, when compared to phacoemulsification, significantly decreases or eliminates EPT altogether. The system is used to perform PhotoEmulsification®, making zero-phaco cataract procedures feasible including in high-grade cataracts (>3). It enables personalized treatment by automatically measuring and adapting the laser energy required to obtain the most efficient cutting of the crystalline lens. This new technology appears to be safe and effective in cataract surgery.

Project description:PurposeThis study aimed to assess preoperative predictors of visual outcome after phacoemulsification cataract surgery in Jordan, a Middle Eastern country.MethodsThis was a retrospective longitudinal study of adult patients who underwent phacoemulsification cataract surgery from January 2019 to July 2021. For each patient, we included only the first operated eye. We obtained pre-operative ocular history, cataract surgery complication risk based on a predesigned score, visual acuity, best correction, and best corrected visual acuity. We recorded intraoperative complications. We also obtained postoperative best corrected visual acuity and refractive error for correction after 1-3 months.ResultsA total of 1,370 patients were included in this study, with a mean age of 66.39 (± 9.48). 48.4% of patients achieved visual acuity ≥ 0.8, and 72.7% achieved visual acuity ≥ 0.5. The mean visual acuity improvement after phacoemulsification cataract surgery was 0.33 (95% CI 0.31-0.35). In the regression model, significant predictors that affected visual acuity improvement included the presence of diabetic retinopathy, glaucoma, and complication risk factors (i.e., high-risk surgery).ConclusionPredictors of visual acuity improvement vary between studies. This study was conducted in a developing country; we defined predictors of visual acuity improvement. We also provided a new preoperative phacoemulsification cataract surgery complication risk score.
