Clinical macular edema following uneventful cataract surgery in eyes without pre-existing fundus diseases: risk factors and treatment prognosis.

BACKGROUND: To investigate the risk factors and prognosis of clinical pseudophakic cystoid macular edema (PCME) after uneventful phacoemulsification surgery in patients without pre-existing fundus diseases. METHODS: This was a retrospective case-control study. Medical records between August 2020 and August 2023 were reviewed for patients who had no previous fundus diseases and developed clinical PCME. A control group was randomly chosen and the risk factors for PCME was analyzed by binary logistic regression. Structure and visual prognosis of the PCME cohort were observed and compared among subgroups undergoing different treatment measures. RESULTS: Forty-seven eyes of 47 patients with PCME were included. The development of PCME was associated with higher systolic blood pressure (OR, 1.048; 95%CI 1.002, 1.097; P = .042), no posterior vitreous detachment (OR, 0.215; 95%CI: 0.553, 0.887; P = .032) and shorter axial lengths (OR, 0.401; 95%CI 0.161, 0.997; P = .049) compared to controls. During a mean follow-up of 8.26 months, 36 eyes (76.6%) showed visual improvement with decreased macular thickness. Different treatment modalities, including observation, topical NSAIDs, and intervention therapy, have no significant differences on the visual prognosis (P = 1.000). However, the intervention group had a shorter recovery time compared to the observation group (28.6 vs. 45.9 days, P = .037). CONCLUSION: PCME remains an encountered morbidity in patients without pre-existing fundus diseases. Shorter axial lengths, absence of posterior vitreous detachment, and higher systolic blood pressure are risk factors of PCME. Active intervention failed to improve the prognosis of PCME but could shorten the recovery time.

Characteristics of pseudophakic retinal detachment and risk factors of recurrence.

BACKGROUND: The present study was designed to gain knowledge about the prognostic factors and evolution of pseudophakic retinal detachment (PRD) and to analyse the main characteristics of PRD, such as the mean time to retinal detachment following cataract surgery, as well as the clinical factors associated with the risk of recurrence and worse anatomical and functional outcomes. METHODS: This was a retrospective monocentric study of 330 patients with PRD who underwent surgery between 2012 and 2020. All patients were pseudophakic and were referred for retinal detachment surgery at Donostia University Hospital (Terciary Hospital, Spain). RESULTS: The mean age of the patients at the time of phacoemulsification was 63.06 ±â€¯10.8 years, and 49.09% of them had moderate myopia [axial length (AL) (23.5-26.5 mm)]. In our series, macular detachment was evident in 69.09% (n = 228) of the patients. The mean time that elapsed between phacoemulsification and PRD surgery was 4.04 ±â€¯4.17 years, which was reduced by half in the event of surgical complications (2.24 ±â€¯2.65). The rate of PRD was 28.79%. The anatomical results in terms of retinal reapplication were better with the combination of vitrectomy and scleral buckling (83.1% vs. 70.5%) (p = 0,127) compared with vitrectomy. The variables associated with a higher risk of recurrence were male sex (hazard ratio (HR) = 1.75), macular detachment (HR = 2.00) and the presence of proliferative vitreoretinopathy (PVR) (HR = 3.21). CONCLUSIONS: PRD usually occurs within 4 years of phacoemulsification, although it may occur significantly earlier in the event of surgical complications. Macular involvement, PVR, and male sex are all associated with a higher risk of PRD recurrence.

Aflibercept vs. dexamethasone implant for recalcitrant diabetic macular edema in pseudophakic eyes - 1-year outcomes from a quazi-randomized study in India.

PURPOSE: To assess the safety and efficacy of intravitreal Aflibercept (IVA) versus dexamethasone (DEX) implant for treating recalcitrant diabetic macular edema (DME) in pseudophakic eyes at 1-year follow-up. DESIGN: Retrospective comparative case series. PARTICIPANTS: Data of all patients diagnosed with DME between January 2019 and December 2021, who underwent 4-monthly doses of intravitreal ranibizumab but had persistent DME [central macular thickness (CMT) within 10% of baseline value] were extracted from a computerized database. Of these, only pseudophakic eyes that underwent either IVA or DEX implant and had at least 1-year follow-up were included for analysis. METHODS: DEX implant was preferred before December 2020 and IVA after this time point. In the IVA group, patients were followed up every month while DEX were followed at least every 3 months. Reinjections were considered when vision dropped by at least 1 Snellen's line or CMT increased by at least 10% from the previous visit in both groups. MAIN OUTCOME MEASURES: Comparison of change in vision and CMT at 1-year follow-up in DEX versus IVA groups. RESULTS: Eighty-four eyes of 84 patients aged 54.4 + 4.4 years were included, 39 (46%) received DEX and 45 (54%) received IVA. Groups were comparable for baseline vision and CMT. Vision improved equally in both groups from 0.83 + 0.15 logMAR to 0.52 + 0.10 logMAR at 3 months ( P < 0.01) and then stabilized till 1 year. However, eyes in the IVA group were 6.5 times more likely (Odds ratio = 6.45, 95% CI = 1.3 - 31.9) to achieve >3-line improvement in vision. The CMT reduction was also comparable between groups (-169 + 51 in DEX vs. -174 + 49 in IVA, P = 0.67). More eyes in the IVA group required >3 injections (91% vs. 69% in DEX, P = 0.01). The IOP was significantly higher at 6 and 9 months in the DEX group and 5 eyes (13%) required IOP lowering medications. CONCLUSION: In pseudophakic eyes with recalcitrant DME not responding to ranibizumab, switching to IVA or DEX implant results in equal visual improvement and CMT reduction. Though >3-line improvement occurs more frequently with IVA, this comes at the expense of a greater number of injections and follow-up visits.

Phacoemulsification with implantation of a trifocal intraocular lens in eyes with asteroid hyalosis and synchysis scintillans.

PURPOSE: To compare the visual outcomes in both eyes of patients who undergo phacoemulsification and trifocal intraocular lens (IOL) implantation and have asteroid hyalosis (AH) or synchysis scintillans (SS) in only one eye. METHODS: A retrospective comparative case series was performed. We evaluated uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), predictability, safety, efficacy, and satisfaction after implantation of the same model of trifocal IOL in both eyes (PhysIOL FineVision Pod-F and Micro-F and Rayner RayOne Trifocal). RESULTS: A total of 164 eyes of 82 patients (41 females, 50%) met the inclusion criteria. There were no statistically significant differences in sphere, cylinder, spherical equivalent, UDVA, UIVA, or UNVA between the groups. Postoperative CDVA was slightly better in the control group (logMAR 0.03) than in the AH/SS group (logMAR 0.04) (P: 0.014). There were no statistically significant differences in predictability, safety index, or efficacy index between the groups. Overall subjective satisfaction was good (98.2%). CONCLUSIONS: Visual outcomes and satisfaction are good after implantation of trifocal IOLs in eyes with AH or SS. Therefore, trifocal IOLs should not be ruled out in these patients when no other vitreoretinal disorder is present.

SF 6 COMPARED WITH C 2 F 6 FOR INFERIOR RHEGMATOGENOUS RETINAL REPAIR : The Manchester Pseudophakic Retinal Detachment Study.

PURPOSE: To compare SF 6 relative with C 2 F 6 in the anatomical and functional outcomes following pars plana vitrectomy for uncomplicated primary pseudophakic rhegmatogenous retinal detachment with inferior causative breaks. METHODS: This is a retrospective, comparative study on eyes with pseudophakic rhegmatogenous retinal detachment with inferior causative breaks that had small-gauge pars plana vitrectomy repair using SF 6 and C 2 F 6 tamponade between 2011 and 2020 at a tertiary centre in the United Kingdom. Primary outcome was single surgery anatomical success, and the secondary outcome was best-corrected visual acuity. Propensity score matching, using preoperative findings as covariates to account for relevant confounders, was performed. RESULTS: From 162 pseudophakic rhegmatogenous retinal detachment eyes with inferior causative breaks, the median (interquartile range) follow-up was 82 (52-182) days. The single surgery anatomical success was 156 (96.3%) overall: 47 of 47 (100.0%) and 109 of 115 (94.8%) in the SF 6 and C 2 F 6 groups, respectively ( P = 0.182). Relative to the SF 6 group, the C 2 F 6 group had a higher mean number of tears (SF 6 : 3.1[2.0], C 2 F 6 : 4.5[2.7], P = 0.002) and greater retinal detachment extent (SF 6 : 5.3[2.9], C 2 F 6 : 6.2[2.6] clock hours, P = 0.025). Following propensity score matching analysis, 80 eyes were matched with 40 in each group to homogenize preoperative factors. No significant difference was found in single surgery anatomical success and best-corrected visual acuity between the groups following propensity score matching. CONCLUSION: Primary pars plana vitrectomy with gas tamponade leads to a high single surgery anatomical success rate in uncomplicated pseudophakic rhegmatogenous retinal detachment with inferior causative breaks with no additional benefit associated with long-acting tamponade when comparing C 2 F 6 with SF 6 .

Pseudophakia as a surprising protective factor in neovascular age-related macular degeneration.

PURPOSE: To assess the impact of lens status on macular function among patients treated for neovascular age-related macular degeneration (nvAMD) in whom scheduled intravitreal injections were delayed. METHODS: We reviewed demographic and clinical data as well as macular optical coherence tomographic images of 34 patients (48 eyes) who did not follow their injection schedule during the first wave of COVID-19 in Israel. Functional worsening was defined as a loss of at least 0.1 in decimal best-corrected visual acuity (BCVA). Morphological worsening was defined as new or increased subretinal/intraretinal fluid or a new hemorrhage. OCT indices of quality were used as a measure for cataract density and progression. RESULTS: Pseudophakia was associated with a better functional outcome than phakic status: there was a loss of 0.06±0.12 vs. 0.15±0.10 decimal BCVA in the pseudophakic and phakic eyes, respectively (P=.001). A similar trend was observed for morphological changes over the same period: there was an increase in macular thickness of 9±26% vs.12±40%, respectively (P=0.79). During the first wave of COVID-19, the index of OCT quality remained stable for phakic eyes (26±3.6 before the first wave of COVID-19, 26±2.9 afterward; P=1) and pseudophakic eyes (30±2.4 before the first wave of COVID-19, 30±2.6 afterward; P=1). CONCLUSION: Pseudophakic eyes with nvAMD that missed their scheduled intravitreal injections experienced fewer morphological and functional complications than phakic eyes with nvAMD.

Risk factors for secondary ocular hypertension in silicone oil-filled eyes following transconjunctival sutureless vitrectomy - A prospective cohort study.

Purpose: Our aim was to determine the various risk factors for secondary ocular hypertension (OHT) following pars plana vitrectomy (PPV) with silicone oil (SO) injection. Methods: A prospective cohort study was performed on 46 eyes of 42 patients who underwent PPV with SO injection under a single surgeon between January 2020 and July 2021. Complete ophthalmological examination including gonioscopy and Goldmann applanation tonometry was performed preoperatively and on three postoperative visits, that is, day 7, day 30, and day 90. Axial length and lens thickness were measured at baseline using immersion A-scan. Anterior segment optical coherence tomography (OCT) was used for measuring anterior chamber depth (ACD) at baseline and at 3 months. Results: There was a statistically significant increase in intraocular pressure (IOP) (>21 mmHg) on day 7 (4.70 ± 7.754 mmHg), day 30 (5.24 ± 7.481 mmHg), and day 90 (2.39 ± 5.659 mmHg) (P<0.01 for all). Age <50 years, rhegmatogenous retinal detachment (RRD), and pseudophakia had a strong association with short-term OHT on day 7. Preexisting glaucoma was the only independent risk factor for long-term OHT (day 90). Higher baseline IOP and SO emulsification also contributed to long-term OHT. Conclusion: There was a statistically significant elevation in IOP at all postoperative visits. Short-term OHT was associated with younger age (<50 years), RRD, and pseudophakia. Patients with emulsified SO in the anterior chamber, higher baseline IOP, and preexisting glaucoma were at higher risk for long-term OHT.

Associated factors with pseudophakic retinal detachment: Long-term follow-up in a Colombian population.

OBJECTIVE: To identify associated factors with the appearance of pseudophakic retinal detachment in patients with history of cataract surgery. METHODS: Retrospective case-control study of 802 eyes of 783 patients with history of cataract surgery. Cases were patients with pseudophakic retinal detachment (n = 258 eyes), while controls were patients with cataract surgery who did not developed retinal detachment during a 10-year follow-up period (n = 544 eyes). RESULTS: Age at cataract surgery among cases was lower than in the control group (57 ± 13 vs. 67 ± 14 years old, respectively; p < 0.0001). Age at retinal detachment was 59 ± 13 years old (range 6-88) and the time between the cataract surgery and the retinal detachment had a median of 2 years (interquartile range 1-4) with a range of 1 month to 14 years. Associated factors for pseudophakic retinal detachment were younger age (<50 years: adjusted odds ratio [aOR] = 18.03, 95% confidence interval [95%CI] = 5.92-54.87; 50-59 years: aOR = 10.09, 95%CI = 3.37-30.23; and 60-69 years: aOR = 5.48, 95%CI = 1.88-15.93), male sex (aOR = 3.71, 95%CI = 2.54-5.44), anterior vitrectomy (aOR = 3.26, 95%CI = 1.16-9.16), history of retinal detachment in the fellow eye (aOR = 6.95, 95%CI = 3.15-15.31), and intraoperative complications during cataract extraction (aOR = 7.45, 95%CI = 3.54-15.69). CONCLUSIONS: This is the first report of associated factors with pseudophakic retinal detachment in a Colombian population. Surgical complications, sex, and age were found to be associated with retinal detachment. Patients should be aware of these potential risks to make informed decisions about their eye health.

Randomized Controlled Trial of Intraocular Lens Orientation for Dysphotopsia.

PURPOSE: To evaluate whether orientation of the optic-haptic junction of an intraocular lens (IOL) during cataract surgery could decrease the incidence and/or severity of positive and negative dysphotopsia. DESIGN: Prospective, randomized controlled trial. METHODS: A total of 163 patients (326 eyes) in a private practice scheduled to have bilateral implantation of a Tecnis monofocal IOL (ZCB00) (Johnson & Johnson Vision) were randomly assigned to have the optic-haptic junction positioned vertically, horizontally, superonasally, or inferonasally. Patients with known visual field defects or best-corrected vision less than 20/80 were excluded. Patients were surveyed for positive and negative dysphotopsia symptoms at 1 week and 4-6 weeks after surgery. Patients were blinded to the orientation whereas researchers were not. Data were analyzed to compare the differences in positive and negative dysphotopsia incidence and severity. RESULTS: IOL oriented vertically in 82 eyes (25.2%), horizontally in 72 eyes (22.1%), superonasally in 94 eyes (28.8%), and inferonasally in 78 eyes (23.9%). Significant differences were noted between orientations in incidence of negative dysphotopsia at 1 week postoperatively (P = .019) and 4-6 weeks postoperatively (P = .002). Patients in the superonasal group had the worst outcome at both time periods, and the horizontal group had the best outcome at 4-6 weeks. No differences were noted for positive dysphotopsia incidence or severity. CONCLUSIONS: The orientation of the optic-haptic junction of a monofocal IOL was significantly associated with incidence of negative dysphotopsia after surgery, with the horizontal orientation performing best at 4-6 weeks.

Rhegmatogenous retinal detachment repair-does age, sex, and lens status make a difference?

PURPOSE: To analyze the correlation between lens status, age, and sex in the epidemiology and success rates of rhegmatogenous retinal detachment (RRD) surgery. METHODS: The files of all consecutive patients undergoing vitreoretinal surgery for uncomplicated RRD between Jan 2005 und Dec 2020 were retrospectively reviewed. Successful outcome was defined as no retinal redetachment occurring within 3 months after surgery. RESULTS: 5502 eyes with uncomplicated primary RRD were included. Mean age of the patients was 61.1 years (± 13.6 SD). In the age group over 40 years, a male predominance was found. The percentage of pseudophakic RRD increased from 25 to 40% during the 15 years observation period. In the age group 50 to 69 years, patients with pseudophakic detachments were male in 786 out of 1079 cases (72.9%). In the same age group, 1285 of 2110 (60.9%) patients with phakic RRD were male. Overall, primary success rate after one procedure was 91.2% (5018 of 5502). In the phakic eyes, the primary success rate was higher in those eyes that underwent combined phacovitrectomy (93.0%), compared to those without simultaneous cataract surgery (88.7%; p = 0.002). CONCLUSION: The ratio of male and female patients with RRD varies between age groups. The proportion of pseudophakic RRD has increased within 15 years. The male predominance in RRD is stronger in pseudophakic than in phakic eyes. In phakic eyes with RRD, a combined phacovitrectomy yielded better anatomical results.

A Rare Cause Of High Astigmatism In Pseudophakia.

We present a case of a 65-year-old Pakistani woman who underwent an uneventful standard left phacoemulsification with posterior chamber intra-ocular lens placement for a mature senile cataract. She was observed to develop post-operative astigmatism secondary to a tilted intra-ocular lens and required repeat surgical intervention to correct the malposition. Per-operatively, the lens was found to be defective with a fixed bend at the haptic-optic junction which necessitated the need for an intra-ocular lens exchange procedure that restored adequate vision. The study highlighted defects in the structural integrity of intra-ocular lenses as an important differential to consider in such cases, and established lens replacement as a successful intervention to improve visual outcome.

Outcomes of the infantile cataract surgery: case series with a 5-year follow-up.

PURPOSE: To present the 5-year outcomes obtained from the infantile cataract surgery in pediatric population. METHODS: Medical records of all patients with unilateral or bilateral infantile cataract who had undergone lensectomy and anterior vitrectomy with or without intraocular lens implantation before 10 years of age were evaluated. Patients with any history of ocular trauma, retinal or corneal dystrophy, ocular or orbital surgery, retinopathy of prematurity, raised intraocular pressure at the time of diagnosis, or incomplete follow-up sessions were excluded from the research. RESULTS: A total of 85 eyes belonged to 52 patients were analyzed. Bilateral and unilateral diseases were present in 33 (63.5%) and 19 (36.5%) patients, respectively. After performing the first operation, 43 (50.6%) eyes still remained aphakic. The mean corrected distance visual acuity (CDVA) of the aphakic and pseudophakic eyes was estimated as 0.77 ± 0.52 and 0.43 ± 0.39 logMAR with no statistical difference. The age at the time of performing the cataract surgery was not associated with the final CDVA in either group. Complications in the anterior segment structures were noted in 39 (45%) eyes. Strabismus and amblyopia were noted in 52 (61%) and 75 (88.2%) eyes, respectively. Glaucoma was found in 17 (20%) eyes with no correlation with the final CDVA, age at the time of cataract surgery, or the status of the lens. CONCLUSION: Due to high prevalence rates of amblyopia, strabismus, and glaucoma after the infantile cataract surgery, specific attention should be paid to these complications in each follow-up examination.

Long-Term Outcome of Descemet Membrane Endothelial Keratoplasty in Eyes With Fuchs Endothelial Corneal Dystrophy Versus Pseudophakic Bullous Keratopathy.

PURPOSE: The aim of this study was to compare the long-term outcome of Descemet membrane endothelial keratoplasty (DMEK) in patients with Fuchs endothelial corneal dystrophy (FECD) and pseudophakic bullous keratopathy (PBK). METHODS: Records of consecutive DMEK surgeries performed between 2015 and 2016 at the Department of Ophthalmology, Cologne, Germany, were retrospectively reviewed from the prospective Cologne DMEK Database. Eyes with either PBK or FECD with a complete 3-year follow-up were enrolled. Main outcome parameters included central corneal thickness (CCT), peripheral corneal thickness (PCT), best spectacle-corrected visual acuity (BSCVA, logarithm of the Minimum Angle of Resolution), and endothelial cell count (ECC) before and after DMEK. RESULTS: Four hundred two eyes from 402 patients were included (FECD n = 371, PBK n = 31). Preoperatively, CCT (FECD: 681.91 ± 146.78 µm; PBK: 932.25 ± 319.84 µm) and PCT (FECD: 732.26 ± 98.22 µm; PBK: 867.54 ± 88.72 µm) were significantly higher in the PBK group (P < 0.01). Three years after DMEK, CCT (FECD: 526.56 ± 27.94 µm; PBK 663.71 ± 132.36 µm) was significantly lower in both groups compared with the preoperative values (P < 0.01), whereas PCT showed no significant difference. PCT increased during the course in the PBK group from month 12 after DMEK (12 mo: 783.73 ± 127.73 µm; 24 mo: 837.50 ± 110.19 µm; 36 mo: 857.79 ± 140.76 µm). The increase in PCT correlated with an accelerated ECC loss starting 12 months after DMEK (P = 0.036). Before DMEK, BSCVA in FECD was significantly higher (P < 0.001) compared with that in PBK. After 3 years, BSCVA improved in FECD and PBK eyes without significant difference (P = 0.239). CONCLUSIONS: Visual acuity after DMEK in PBK and FECD seems to be comparable during the long-term follow-up. Peripheral and central corneal edema seems to recur faster in eyes with PBK than in those with FECD. Therefore, using a donor graft with higher ECC or possibly a larger graft could be a promising approach for PBK patients.

In-depth analysis of risk factors for pseudophakic retinal detachments and retinal breaks.

PURPOSE: To provide a detailed analysis of risk factors for pseudophakic retinal detachments (PRD) and pseudophakic retinal breaks (PRB). MATERIALS AND METHODS: We reviewed the medical records of cataract surgeries between 1996 and 2017 at a tertiary care hospital in Austria. A Cox proportional-hazard regression model was used to analyse risk factors for PRD and PRB. RESULTS: Sixty-five thousand six hundred and sixty-two eyes (45 043 patients) underwent phacoemulsification, and 393 eyes (cumulative incidence 0.6%) were diagnosed with PRD (327 eyes) or PRB (66 eyes) during the follow-up (median 7.1 years, range 0-21). Calculation of adjusted hazard ratios (HR) revealed a hierarchy of risk factors for either event including (from the highest to the lowest risk) posterior capsular rupture (PCR), patient age <65 years (compared with the age group >75 years), male gender and high myopia. Diabetes mellitus was associated with a lower risk. PCR was the strongest risk factor for PRD both in patients with and without perioperative vitrectomy (i.e. vitreous loss), but time to PRD was significantly reduced only following PCR with vitrectomy. CONCLUSIONS: Posterior capsular rupture, young patient age, male gender and high myopia were risk factors for PRD, but diabetes mellitus was associated with a lower risk. PCR had the strongest association with PRD, regardless of the need for perioperative vitrectomy due to vitreous loss. Time to PRD was reduced in patients with PCR and vitrectomy compared with PCR without the need for vitrectomy or uneventful surgery.

Resolution of Pseudophakic Cystoid Macular Edema: 2 mg Intravitreal Triamcinolone Acetonide versus 40 mg Posterior Sub-Tenon Triamcinolone Acetonide.

PURPOSE: To compare 2 mg intravitreal triamcinolone (IVT) versus 40 mg posterior sub-Tenon triamcinolone acetonide (STT) for the treatment of eyes with pseudophakic cystoid macular edema. METHODS: A retrospective, single-center review of eyes receiving 2 mg IVT between 3/1/2012-3/1/2017 and 40 mg STT between 1/1/2015-3/1/2017. Visual acuity (VA) and central macular thickness (CMT) were recorded at baseline, 1-, 3-, and 6-month follow-up visits. RESULTS: Forty-five eyes were included in the IVT group and 50 eyes in the STT group. Change in VA from baseline to 1, 3, and 6 months was not significantly different between IVT and STT (6 months: 2.3 lines vs. 2.4 lines, p = .10). The IVT group achieved significantly better CMT improvement from baseline compared to STT at 1 month (255 µm vs. 187 µm; p = .03), but this difference was not present at month 3 (214 µm vs. 212 µm; p = .79) or month 6 (176 µm vs. 207 µm; p = .29). During the 6-month follow-up period, approximately 7% of eyes in the IVT group and 12% of eyes in the STT group developed ocular hypertension (p = .43), and all cases were successfully managed with topical anti-ocular hypertensive therapy or observation. CONCLUSIONS: 2 mg IVT and 40 mg STT both achieved significant improvement in vision and CMT with no significant difference between interventions at 3- and 6-month follow-up.

Techniques, Outcomes, and Complications of Preloaded, Trifolded Descemet Membrane Endothelial Keratoplasty Using the DMEK EndoGlide.

PURPOSE: To describe 2 insertion techniques, outcomes, and complications of preloaded, trifolded Descemet membrane endothelial keratoplasty (DMEK) cases using the DMEK EndoGlide inserter. METHODS: This retrospective, consecutive case series analyzed the first 35 cases using the DMEK EndoGlide performed between October 2018 and October 2019 at a single center. Preloaded, trifolded DMEK tissues were delivered through a fluid-injected or pull-through technique. To inject the tissue, a burst of fluid was delivered into the lumen of the injector with a second instrument. Postoperatively, best-spectacle corrected visual acuity (BSCVA), pachymetry, graft survival, and complications were assessed. RESULTS: Thirty-five eyes of 29 patients underwent DMEK alone (n = 11), with cataract surgery (n = 21), or with additional surgeries (n = 3). Of these, 19 (54.3%) grafts were injected. Video analysis revealed a median time of 3.5 minutes from graft insertion to opening for gas insertion. Median preoperative BSCVA of 0.398 logMAR improved to 0.097 logMAR (P = 0.02) at 9 months. Median pachymetry decreased from 619 µm to 551 µm (P = 0.03) at 9 months. Median donor endothelial cell count of 2890.5 cells/mm2 reduced to 2123 cells/mm2 (26.6% endothelial cell loss; P = 0.008) 6 months postoperatively. One (2.9%) graft failed due to inverted marking at the eye bank and subsequent reverse implantation. CONCLUSIONS: Pre-loaded, tri-folded tissues can be implanted with acceptable levels of endothelial cell loss. We describe a no-touch method of injecting pre-loaded, tri-folded tissue and highlight incorrect marking as a potential complication. This may not be identifiable intraoperatively due to lack of scroll formation.

Nd:YAG Laser Posterior Capsulotomy in Adult Patients with Uveitis.

Purpose: To study the complication rate of Nd:YAG laser posterior capsulotomy in patients with uveitis.Method: Retrospective case note analysis of pseudophakic uveitis patients having undergone Nd:YAG laser posterior capsulotomy between January 2016 and December 2018. Complications documented included uveitis flare, raised intraocular pressure, intraocular lens damage/displacement, cystoid macular edema, and retinal detachment.Results: There were 39 eyes of 38 patients (20M, 18F; age 27-89 years). Mean interval between cataract surgery and laser was 55 months (range 8-286 months). Mean laser energy was 79 mJ (range 33-207 mJ). At 3 months 62% of eyes achieved a 2-5 Snellen line improvement that was maintained at 12 months. Vision was unchanged in 21% of eyes due to preexisting pathology, with no eyes having worse vision. No post-laser complications were documented.Conclusions: Nd:YAG laser posterior capsulotomy is a safe procedure in uveitis patients, resulting in a good improvement in vision.
