Distribution of preoperative angle alpha and angle kappa values in patients undergoing multifocal refractive lens surgery based on a positive contact lens test

Abstract Purpose To assess the preoperative objective angle alpha and angle kappa measurements of patients deciding to undergo multifocal refractive lens surgery based on a subjective positive multifocal contact lens test (MCLT). Methods Retrospective, consecutive case series. Alpha and kappa angles were measured using the iTrace aberrometer. All patients also performed a 1-week MCLT. Only patients with a positive MCLT underwent surgery. Visual outcome (UCVA) was obtained in the 1-year follow-up. We assessed the preoperative distribution of angle values within MCLT positive and negative patient groups. Results Two hundred seventeen eyes (111 patients) were included. Mean age was 56.4 years (SD 5.6) and 46.9% were female. In 71 eyes (38 patients), MCLT was positive. Of them, 12 eyes (17%) had an angle alpha and angle kappa ≥ 0.5mm. Of 146 eyes (73 patients) who refrained from surgery due to a negative MCLT, 71 eyes (48.6%) had both angles small (<0.5mm). In the 1-year follow-up, UCVA improved by 0.68 logMAR (SD 0.51; p<0.001) from baseline. Eyes with both small angle alpha and kappa sizes improved by 0.78 logMAR (SD 0.56), as did eyes with high (≥0.5mm) angle sizes (0.82 logMAR (SD 0.53). UCVA of eyes (n=24) with high alpha but low kappa sizes improved less (−0.31 logMAR (SD 0.13; p=0.019)). Conclusion Four out of five patients with a positive MCLT also had correspondingly small angle values. One-half of patients with low preoperative angle values refrained from surgery due to a negative MCLT result. One-year visual acuity improvement was substantial and independent from angle sizes.

Abstract In this single center case series with nine percent primary diversion, 86 of 94 patients alive and with complete follow-up at one year had a functioning anastomosis. Seventy-five of the initial 99 patients never had a stoma. Meaning: Highly selective fecal diversion in combination with proactive leakage management, low anastomoses can be preserved safely, and the majority of patients will be spared all disadvantages of a diverting stoma. In this single-centre case series, with a primary diversion rate of 9 per cent, 86 of 94 patients who were alive and had complete follow-up at 1 year had a functioning anastomosis. Seventy-five of the initial 99 patients never had a stoma. The results indicate that, with highly selective faecal diversion in combination with proactive leakage management, low anastomoses can be preserved safely, and the majority of patients will be spared the disadvantages of a diverting stoma.

Purpose: We evaluated the refractive visual outcomes and efficacy of Transepithelial Photorefractive Keratectomy (TransPRK) using Smart Pulse Technology with static and dynamic cyclotorsion and the AMARIS 1050 Hz RS laser platform from Schwind in the eyes after a refractive lens exchange. Setting/Venue: Aurelios Augenlaserzentrum, Recklinghausen. Methods: We retrospectively evaluated the data of 552 consecutive eyes treated with refractive lens exchange between 2016 and 2019. A total of 47 eyes (8.5%) required a touch up after the clear lens exchange. From 43 eyes of 43 patients, we obtained a minimum follow up of 3 months. In all cases, we performed a TransPRK with a minimum optical zone of 7.2 mm, centering the ablation on the vertex of the cornea. Results: The average age of the treated eyes was 57 years old, with a range between 48 and 68 years. The mean treated sphere was 0.42 diopters (D), with a range between −1.0 and +1.75 D. The mean astigmatism was 1.06 D. Postoperatively, after laser vision correction, we reduced the sphere to a mean of 0.11 D (range −0.5 to +0.75 D), and, postoperatively, the mean astigmatism was 0.25 D (range −0.75 to 0 D). The predictability for a spheric equivalent (SEQ) of 0.5 D was 91%, and for 1 D it was 100% of the cases. No eye lost more than one Snellen line. Conclusions: TransPRK with smart pulse was predictable for correcting ametropia after Clear Lens Surgery.

Purpose: To describe the treatment outcomes and prognostic factors of retinotomy/retinectomy for rhegmatogenous retinal detachment (RD) complicated anterior inferior proliferative vitreoretinopathy (PVR). Methods: Retrospective, nonrandomized, single-center case series. The outcomes of 126 cases of retinotomy/retinectomy for RD complicated by advanced (Grade C) anterior inferior PVR managed consistently by one surgeon during a 15-year period were evaluated. Results: Forty-two eyes (33%) had primary RDs and 84 (67%) had recurrent RDs. The extent of retinotomy/retinectomy varied: 90° in 21 eyes (17%), >90° to <180° in 49 eyes (39%), and ⩾180° to ⩽240° in 56 eyes (44%). The retinotomy/retinectomy location was peripheral in 58 eyes (46%) and equatorial in 68 eyes (54%). The mean follow-up period was 43 ± 42 months. The silicone oil (SO) was removed from 98% of the eyes. The single-operation success rate after the primary retinectomy was 87%, and the final attachment rate was 94%. Visual acuity improved from 20/630 to 20/160 ( p < 0.001). Vision ⩾20/200 was achieved in 101 eyes (80%). Good visual outcome was correlated positively with preoperative VA ( p = 0.02), previous vitrectomy with gas tamponade ( p = 0.007), and was negatively correlated with number of previous RD operations ( p = 0.01), larger extent of RD ( p = 0.02) and more extensive retinotomy/retinectomy ( p = 0.04). Conclusions: An appropriate and timely intervention, including vitrectomy alone, inferior relaxing retinotomy/retinectomy and standard SO tamponade provide satisfactory outcomes for RDs complicated by PVR. Lesser extension of grade C PVR at baseline, such as PVR limited to one quadrant should encourage vitreoretinal specialists to consider retinotomy/retinectomy at a milder clinical stage of PVR development.

Abstract Background The Cartiva implant (CI) is being increasingly used in the surgical therapy of hallux rigidus. Despite a growing number of studies, numerous questions regarding patient selection remain unanswered. Patients and Methods As part of a retrospective case series with prospective follow-up (average follow-up period: 12 months), a total of 44 patients (male/female = 16/28; mean age at the time of surgery: 55.4 years) with 44 CI were analysed (VAS, EFAS-, AOFAS-score). Using a correlation analysis and a machine learning algorithm, risk factors for therapy failure were investigated. Results The overall survival rate of the CI was 93% at 12 months. The VAS, EFAS and AOFAS scores showed a significant improvement in comparison to the preoperative condition. The mobility of the metatarsophalangeal joint showed no increase. Patients with a medium osteoarthritis grade and a medium level of clinical restraint showed the greatest improvement in relation to their preoperative condition. Conclusion The CI can be seen as an effective therapy for hallux rigidus. Nonetheless, realistic patient expectations must be communicated.

Abstract Background: The aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using 3D replicas. Methods: Ten patients underwent teeth autotransplantation with or without GBR. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during two years following up, which were transplanted into fresh molar sockets by using 3D replicas, and GBR when it is necessary. Results: The average extra-oral time of donor tooth had been shortened to 1.65 min when used the 3D replica. Some probing depth of the transplanted tooth were deeper than 3 mm at 4 or 5 weeks temporarily. And one patient felt slight sensitive when chewing with soft food at 4 weeks, then disappeared. The clinical examination of the autotransplantation teeth during one year follow-up showed no sign of failure. Conclusions: The tooth autotransplantation using 3D replica with or without GBR is an effective method which can reduce the extra-oral time of the donor teeth and may result in less failure.

Purpose: To investigate characteristics of Open Globe Injuries (OGI) that presented with Intra-Ocular Foreign Body (IOFB), along with their long-term visual outcomes and complications. Methods: Retrospective interventional consecutive case series of OGIs with IOFBs that presented at Massachusetts Eye and Ear from 2010 to 2015. Data collected included time from injury to OGI repair, location of IOFB, retinal detachment (RD) rate, presenting and final visual acuity and subsequent surgeries. Results: Fifty-seven consecutive cases of OGIs with IOFBs were included. Mean follow-up was 28 months and median time from injury to OGI repair was 0 days. Overall, 38/57 (66.7%) eyes achieved final vision of 20/40 or better and 43/57 (75.4%) 20/150 or better. Thirty-three cases had IOFBs in the anterior segment only, 24 cases had posterior segment involvement. Thirty percent of cases (17/57) were complicated by an RD, 58.3% (14/24) in the posterior versus 9.1% (3/33) in the anterior IOFB group ( P = .01). There were no cases of endophthalmitis. Posterior IOFB and higher zone of injury were risk factors for RD both at presentation (both P < .001) and post-primary repair (both P < .001). Posterior IOFB was associated with higher vitrectomy rates both at presentation ( P < .001) and post-primary repair ( P = .002) and worse long-term visual outcome ( P = .01). Conclusions: OGIs with IOFB involving the posterior segment are associated with higher complication and re-operation rates and worse visual prognosis compared to those involving the anterior segment only.

Introduction. To evaluate outcomes of wide-diameter (6 mm) implants immediately provisionalized with cement-retained single crowns in posterior molar sites.Materials and Methods. Forty-eight consecutive patients received a total of 53 moderately rough-surface, 6 mm diameter implants in healed sites. All implants were immediately provisionalized with a cement-retained provisional crown. Final prosthesis with cement-retained porcelain fused to metal crowns was delivered 3–6 months later. Patients were followed up for 1 year. Outcome measures were implant failures and success rate, complications, marginal bone levels, bone level changes, papilla index, bleeding on probing, and inflammation.Results. One patient was lost to follow-up. At one year, the implant survival and success rate were 98.1%. The mean marginal bone loss after 1 year was −0.17±1.84 mm. Ideal papilla score was recorded at 83.8% of the sites. More than 95.6% of the sites showed no bleeding or inflammation. No procedure-related or device-related adverse events were reported.Conclusion. Wide-diameter (6 mm) implants can safely and successfully replace single posterior molars. Longer follow-up studies are necessary to evaluate the long-term success of these implants.

Purpose: This article reports the clinical features, associations, and outcomes of patients with full-thickness macular hole (MH) formation after pars plana vitrectomy for retinal detachment (RD). Methods: A retrospective, interventional case series is presented of consecutive patients undergoing surgical repair of MH following prior tractional or rhegmatogenous retinal detachment repair from September 2014 to October 2018 at a single vitreoretinal surgery practice. The size of the MH, presence of epiretinal membrane (ERM), rate of MH closure, and visual outcome following repair were evaluated. Results: A total of 996 cases of rhegmatogenous and tractional retinal detachment repair were identified. The average time from the RD surgery to MH diagnosis was 72 days. The incidence of subsequent MH formation in patients who underwent surgery was 0.8% (8/996). The presence of ERM prior to MH repair was noted in 50% of these cases (4/8). In cases with at least 3 months of postoperative follow-up, MH closure was achieved in 100% of eyes after a single surgery. The mean preoperative visual acuity (VA) was 2.06 logMAR (logarithm of the minimum angle of resolution) units (Snellen equivalent, 20/2296) and significantly improved to 0.72 logMAR units (Snellen, 20/104; P = .017) at the last follow-up after MH repair. All patients had improvement in VA at the final postoperative visit, with a VA of 20/200 or better achieved in 87.5% of cases. Conclusions: Although MH formation after successful RD repair is uncommon, favorable visual and anatomic results can be obtained.

Background: Pediatric aortic root dilatation is a life-threatening condition that lacks guidelines for surgical management. We aimed to analyze the data on aortic valve interventions during root surgery to guide decision-making. Methods: A search was performed of MEDLINE, Embase, CENTRAL, ClinicalTrials.gov , and WHO ICTRP. Citations were screened in duplicate and independently to identify randomized controlled trials, cohorts, and case series involving populations aged 0 to 18 years, who received valve-sparing and valve-replacing aortic root surgeries between 1999 and 2019. Outcomes considered included mortality (perioperative, one year, five year), reintervention rates. Results: After duplicate removal, 689 citations were screened through abstract and full text review, identifying five eligible studies. All five were observational studies evaluating valve-sparing procedures. There were 81 patients with a mean study age range of 9.9 to 13.9 years. Both reimplantation (74%) and remodeling (26%) subtypes were done. Range of mean duration of follow-up was 1.2 to 4.4 years. There was no mortality reported until the one-year follow-up period. The long-term mortality rate was calculated as 0.02 per patient-year (95% CI: 0.01-0.05). The long-term reintervention rate was 0.08 per patient-year (95% CI: 0.05-0.13). Conclusions: There is limited experience on aortic valve intervention during aortic root surgery in children. Single-arm studies on valve-sparing surgeries show excellent survival up to one year. Mortality and reintervention rates increase in the longer term. The small sample size and lack of controlled studies do not allow for direct comparisons between procedure types.
