7-Year Efficacy and Safety of iStent inject Trabecular Micro-Bypass in Combined and Standalone Usage.

INTRODUCTION: This study evaluated 7-year effectiveness and safety of second-generation trabecular micro-bypass implantation (iStent inject) either in combination with cataract surgery or as a standalone procedure (Combined or Standalone subgroups, respectively) in eyes with open-angle glaucoma. METHODS: This prospective, non-randomized, unmasked, longitudinal study included 125 consecutive iStent inject cases of a single surgeon at a large German academic hospital. Patients had considerable preoperative disease burden, with mean intraocular pressure (IOP) of 23.5 mmHg, 84.8% of eyes on ≥ 2 medications, and 38.4% of eyes with prior glaucoma surgery. IOP, medications, adverse events, and secondary surgeries were assessed through 7 years in the Overall cohort and in Combined (n = 81) and Standalone (n = 44) subgroups. RESULTS: Over 7-year follow-up, mean IOP decreased by 36.2-40.0% in Overall eyes, 34.1-38.9% in Combined eyes, and 39.5-43.5% in Standalone eyes (p < 0.001 at all timepoints for all groups). Meanwhile, mean medications decreased by 59.3-71.3% in Overall eyes, 57.9-69.0% in Combined eyes, and 62.1-76.2% in Standalone eyes (p < 0.001 at all timepoints in all groups). At last follow-up (mean 77.4 months; 92.8% of patients with last visit at 6 or 7 years), 83.7% of Overall eyes, 82.3% of Combined eyes, and 86.4% of Standalone eyes had achieved ≥ 20% IOP reduction vs preoperative. At last follow-up vs preoperative, 100% of eyes in all groups had the same or lower IOP and 100% had the same or lower medication regimen. Safety outcomes were favorable, with no filtration surgeries and only 4.84% of eyes experiencing clinically significant visual field loss over 7 years of follow-up. CONCLUSION: iStent inject implantation with or without phacoemulsification produced significant and durable 7-year reductions in IOP (~ 34-44% reduction) and medications (~ 58-76% reduction) while preventing filtering surgery in this cohort of patients with relatively high preoperative disease burden. Combined and Standalone cases had similarly favorable effectiveness and safety.

Relationship Between Baseline Prostate-specific Antigen on Cancer Detection and Prostate Cancer Death: Long-term Follow-up from the European Randomized Study of Screening for Prostate Cancer.

BACKGROUND: The European Association of Urology guidelines recommend a risk-based strategy for prostate cancer screening based on the first prostate-specific antigen (PSA) level and age. OBJECTIVE: To analyze the impact of the first PSA level on prostate cancer (PCa) detection and PCa-specific mortality (PCSM) in a population-based screening trial (repeat screening every 2-4 yr). DESIGN, SETTING, AND PARTICIPANTS: We evaluated 25589 men aged 55-59 yr, 16898 men aged 60-64 yr, and 12936 men aged 65-69 yr who attended at least one screening visit in the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial (screening arm: repeat PSA testing every 2-4 yr and biopsy in cases with elevated PSA; control arm: no active screening offered) during 16-yr follow-up (FU). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We assessed the actuarial probability for any PCa and for clinically significant (cs)PCa (Gleason ≥7). Cox proportional-hazards regression was performed to assess whether the association between baseline PSA and PCSM was comparable for all age groups. A Lorenz curve was computed to assess the association between baseline PSA and PCSM for men aged 60-61 yr. RESULTS AND LIMITATIONS: The overall actuarial probability at 16 yr ranged from 12% to 16% for any PCa and from 3.7% to 5.7% for csPCa across the age groups. The actuarial probability of csPCa at 16 yr ranged from 1.2-1.5% for men with PSA <1.0 ng/ml to 13.3-13.8% for men with PSA ≥3.0 ng/ml. The association between baseline PSA and PCSM differed marginally among the three age groups. A Lorenz curve for men aged 60-61 yr showed that 92% of lethal PCa cases occurred among those with PSA above the median (1.21 ng/ml). In addition, for men initially screened at age 60-61 yr with baseline PSA <2 ng/ml, further continuation of screening is unlikely to be beneficial after the age of 68-70 yr if PSA is still <2 ng/ml. No case of PCSM emerged in the subsequent 8 yr (up to age 76-78 yr). A limitation is that these results may not be generalizable to an opportunistic screening setting or to contemporary clinical practice. CONCLUSIONS: In all age groups, baseline PSA can guide decisions on the repeat screening interval. Baseline PSA of <1.0 ng/ml for men aged 55-69 yr is a strong indicator to delay or stop further screening. PATIENT SUMMARY: In prostate cancer screening, the patient's baseline PSA (prostate-specific antigen) level can be used to guide decisions on when to repeat screening. The PSA test when used according to current knowledge is valuable in helping to reduce the burden of prostate cancer.

iStent inject Trabecular Micro-Bypass with or Without Cataract Surgery Yields Sustained 5-Year Glaucoma Control.

INTRODUCTION: This study evaluated the 5-year effectiveness and safety of iStent inject® trabecular micro-bypass with or without cataract surgery (Combined or Standalone, respectively) in patients with open-angle glaucoma (OAG). METHODS: This prospective longitudinal case series included consecutive iStent inject cases from a single surgeon at a large German academic hospital. Intraocular pressure (IOP), medications, safety, and indicators of disease stability through 5 years were assessed in the Overall cohort and in subgroup analyses stratified by usage (Combined or Standalone). RESULTS: Preoperative mean IOP in the Overall cohort (n = 125) was 23.5 ± 6.2 mmHg on 2.68 ± 1.02 mean medications, reducing to 14.1 ± 1.8 mmHg on 0.77 ± 0.82 medications at 5 years (40% and 71% reductions, respectively; both p < 0.001). All but 1 eye (> 99%) were on medication(s) preoperatively, but 46% were medication-free at 5 years (p < 0.001). In Combined eyes (n = 81), mean IOP decreased by 39% (22.6 mmHg to 13.8 mmHg, p < 0.001) and medications by 69% (2.52 to 0.78, p < 0.001). In Standalone eyes, mean IOP reduced by 42% (25.3 mmHg to 14.6 mmHg, p < 0.001) and medications by 75% (2.98 to 0.74, p < 0.001). At final follow-up, 83% of eyes had achieved ≥ 20% IOP reduction, and all but 1 eye (> 99%) had the same or lower IOP versus preoperative; all eyes (100%) maintained or reduced their medication burden versus preoperative. Favorable safety included 0 intraoperative complications and 0 filtration surgeries through 5 years. Long-term indicators of disease stability (visual fields, retinal nerve-fiber layer thickness, and cup:disc ratio) were unchanged over the course of 5-year follow-up. CONCLUSIONS: iStent inject produced significant and durable 5-year reductions in IOP (nearly 10-mmHg reduction) and medications (nearly 2-medication reduction), with stable disease parameters over time. Combined and Standalone subgroups had similar outcomes.

Long-term follow-up and clinical evaluation of the light-adjustable intraocular lens implanted after cataract removal: 7-year results.

PURPOSE: To determine the long-term safety and effectiveness of a light-adjustable intraocular lens (LAL) over a period that is longer than reported in the literature at the time of the study. SETTING: University Eye Hospital, Bochum, Germany. DESIGN: Noninterventional observation. METHODS: In 445 patients, cataract surgery with LAL implantation was performed between April 2008 and December 2012. It was possible to contact 171 of these patients or their relatives through letter or telephone; 61 patients (103 eyes) agreed to participate in the long-term study and were examined. RESULTS: The mean time between the lock-in (final light treatment) and long-term visit was 7.2 years; 61 patients were included and examined. Corrected and uncorrected distance visual acuity was and remained good (n = 93). The refractive outcome was stable with minimal deviation. There were no significant changes in corneal thickness. In 2 patients, there were slight opacities of the IOL material without impact on visual acuity. Other eye diseases were within the normal range of the patients' age. CONCLUSION: Seven years after implantation and refractive adjustment, eyes with an LAL had stable refraction, good visual acuity, and no IOL-associated pathologies. The findings suggest that LAL technology is a safe and efficient method to achieve good visual results without long-term complications.

[Inguinal hernia - review].

Inguinal hernia is the most frequently diagnosed hernia and during their lifetime one third of males are diagnosed with an inguinal hernia. The age distribution is bimodal with the highest incidence in childhood and after 50 years of age. Diagnosis is usually reached through clinical examination of a lump in the inguinal region although some patients can present with intestinal obstruction. Inguinal hernia repair is the only definitive treatment and is one of the most common surgical procedures performed. It is usually performed as an elective procedure in local, spinal or general anasthesia. The repair constitutes of reinforcing the posterior wall of the inguinal canal, often using a polypropylene mesh; either via an open anterior approach or posteriorly from within the abdomen with laparoscopy. The most common complications following a hernia repair are recurrent hernia and chronic -discomfort but recurrence rates have improved with the use of mesh and laparoscopic techniques. This evidence based review describes the -epidemiology and etiology of inguinal hernia together with the most common surgical procedures; focusing on recent innovations.

Comparison of Minimally Invasive XEN45 Gel Stent Implantation in Glaucoma Patients Without and With Prior Interventional Therapies.

INTRODUCTION: The aim of our analysis was to compare the effectiveness of the XEN45 gel stent implantation in patients without and with prior glaucoma intervention. METHODS: Retrospective analysis including 148 medical records of consecutive glaucoma eyes without prior glaucoma intervention (group A, n = 45) or with prior glaucoma intervention (group B, n = 103). Follow-up data up to 12 months after XEN45 gel implantation were available for all eyes. RESULTS: At 12 months, qualified success (IOP reduction of ≥ 20% and IOP < 18 mmHg without and with medication) was achieved in 76% of eyes in group A and in 72% of eyes in group B; corresponding values for complete success (IOP reduction of ≥ 20% and IOP < 18 mmHg without medication) were 56% and 55%. Mean IOP was significantly reduced by 58% from 36.0 ± 10.7 mmHg preoperatively to 14.2 ± 3.4 mmHg at 12 months in group A (p = 0.000) and by 53% from 31.6 ± 8.9 mmHg to 14.3 ± 4.2 mmHg and in group B (p = 0.000). The mean number of hypotensive medications had significantly decreased from 3.6 ± 0.8 at baseline to 0.3 ± 0.7 medications in group A (p = 0.000) and from 3.0 ± 1.0 to 0.3 ± 0.7 medications in group B (p = 0.000). Needling was required in 29% of eyes in group A and in 35% of group B within 12 months. No statistically significant differences were observed between eyes without and with prior glaucoma intervention. CONCLUSION: The 1-year results of our retrospective analysis indicate that patients without and with previous glaucoma intervention can benefit from XEN45 gel stent implantation. Both groups achieved significant and similar reductions in IOP and hypotensive medication, with a slight trend towards greater reductions in eyes without prior glaucoma intervention. Further controlled prospective studies with longer follow-ups are required. FUNDING: Editorial support and article processing charges were funded by Allergan.

Second-Generation Trabecular Micro-Bypass Stents as Standalone Treatment for Glaucoma: A 36-Month Prospective Study.

INTRODUCTION: To evaluate long-term outcomes following stand-alone implantation of two second-generation trabecular micro-bypass stents (iStent inject®, Glaukos Corp., San Clemente, CA, USA) in eyes with predominantly primary open-angle glaucoma (POAG) and considerable preoperative disease burden. METHODS: Eyes with POAG, pseudoexfoliative glaucoma (PXG), appositional narrow-angle glaucoma (NAG, with open-angle configuration in the area of implantation), or secondary glaucoma were included in this prospective, non-randomized, consecutive case series. All eyes underwent ab interno iStent inject implantation as a sole procedure. Assessments through 36 months included IOP, medications, corrected distance visual acuity (CDVA), secondary glaucoma surgeries, and complications and adverse events. RESULTS: Two iStent inject stents were implanted in 44 consecutive eyes (POAG = 38, PXG = 4, appositional NAG = 1, secondary neovascular glaucoma = 1) of 31 patients, and 33 eyes had 36-month follow-up data. Preoperative mean IOP was 25.3 ± 6.0 mmHg on a mean of 2.98 ± 0.88 medications, with 75% of eyes on 3-5 medications, no eyes medication-free, and 50% of eyes with history of prior glaucoma surgery. At 36 months postoperatively, mean IOP reduced by 42% to 14.6 ± 2.0 mmHg (p < 0.0001) and 87.9% of eyes achieved an IOP reduction of ≥ 20% versus preoperatively. In addition, 97% of eyes reached IOP ≤ 18 mmHg (vs. 9.1% preoperatively; p < 0.0001) and 70.0% of eyes reached IOP ≤ 15 mmHg (vs. 2.3% preoperatively; p < 0.0001). Mean medication burden decreased by 82% to 0.55 ± 0.79 (p < 0.0001), and 61% of eyes became medication-free. All eyes maintained or decreased their 36-month medication burden versus preoperatively. Safety was favorable, including minimal adverse events and stable CDVA through 36 months postoperatively. CONCLUSION: This real-world cohort of glaucomatous eyes with substantial preoperative disease burden experienced significant, sustained, safe IOP and medication reductions through 36 months following stand-alone iStent inject implantation.

A 16-yr Follow-up of the European Randomized study of Screening for Prostate Cancer.

BACKGROUND: The European Randomized study of Screening for Prostate Cancer (ERSPC) has previously demonstrated that prostate-specific antigen (PSA) screening decreases prostate cancer (PCa) mortality. OBJECTIVE: To determine whether PSA screening decreases PCa mortality for up to 16yr and to assess results following adjustment for nonparticipation and the number of screening rounds attended. DESIGN, SETTING, AND PARTICIPANTS: This multicentre population-based randomised screening trial was conducted in eight European countries. Report includes 182160 men, followed up until 2014 (maximum of 16yr), with a predefined core age group of 162389 men (55-69yr), selected from population registry. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The outcome was PCa mortality, also assessed with adjustment for nonparticipation and the number of screening rounds attended. RESULTS AND LIMITATIONS: The rate ratio of PCa mortality was 0.80 (95% confidence interval [CI] 0.72-0.89, p<0.001) at 16yr. The difference in absolute PCa mortality increased from 0.14% at 13yr to 0.18% at 16yr. The number of men needed to be invited for screening to prevent one PCa death was 570 at 16yr compared with 742 at 13yr. The number needed to diagnose was reduced to 18 from 26 at 13yr. Men with PCa detected during the first round had a higher prevalence of PSA >20ng/ml (9.9% compared with 4.1% in the second round, p<0.001) and higher PCa mortality (hazard ratio=1.86, p<0.001) than those detected subsequently. CONCLUSIONS: Findings corroborate earlier results that PSA screening significantly reduces PCa mortality, showing larger absolute benefit with longer follow-up and a reduction in excess incidence. Repeated screening may be important to reduce PCa mortality on a population level. PATIENT SUMMARY: In this report, we looked at the outcomes from prostate cancer in a large European population. We found that repeated screening reduces the risk of dying from prostate cancer.

Results of Prostate Cancer Screening in a Unique Cohort at 19yr of Follow-up.

We assessed the effect of screening in the European Randomized study of Screening for Prostate Cancer (ERSPC) Rotterdam pilot 1 study cohort with men randomized in 1991-1992. A total of 1134 men were randomized on a 1:1 basis to a screening (S) and control (C) arm after prostate-specific antigen (PSA) testing (PSA ≥10.0ng/ml was excluded from randomization). Further PSA testing was offered to all men in the S-arm with 4-yr intervals starting at age 55yr and screened up to the age of 74yr. Overall, a PSA level of ≥3.0ng/ml triggered biopsy. At time of analysis, 63% of men had died. Overall relative risk of metastatic (M+) disease and prostate cancer (PCa) death was 0.46 (95% confidence interval [CI]: 0.19-1.11) and 0.48 (95% CI: 0.17-1.36), respectively, in favor of screening. This ERSPC Rotterdam pilot 1 study cohort, screened in a period without noteworthy contamination, shows that PSA-based screening could result in considerable reductions of M+ disease and mortality which if confirmed in larger datasets should trigger further discussion on pros/cons of PCa screening. PATIENT SUMMARY: In a cohort with 19yr of follow-up, we found indications for a more substantial reduction in metastatic disease and cancer-specific mortality in favor of prostate cancer screening than previously reported. If confirmed in larger cohorts, these findings should be considered in the ongoing discussion on harms and benefits of prostate cancer screening.

Ab interno gel implant in patients with primary open angle glaucoma and pseudoexfoliation glaucoma.

PURPOSE: To compare efficacy and safety results of an ab interno gel implant in patients with pseudoexfoliation glaucoma (PXG) and primary open angle glaucoma (POAG). METHODS: Retrospective analysis of the medical records of 110 consecutive eyes with open angle glaucoma who had received a XEN45 gel implant between March 2014 and June 2015. Intraocular pressure course, number of glaucoma medications, the need for additional intervention (including needling) and complications were evaluated until 12 months postoperatively. RESULTS: Data of 67 eyes with POAG and 43 eyes with PXG were analyzed. At 12 months postoperatively, the mean IOP had significantly decreased by 54.0% from preoperatively 31.85 ± 8.5 mmHg to 13.99 ± 2.6 mmHg in the POAG group, (p = 0.000; Wilcoxon test), and by 55.2% from 31.63 ± 9.0 mmHg to 13.28 ± 3.1 mmHg in the PXG group (p = 0.000; Wilcoxon test). The mean number of anti-glaucoma medications had significantly decreased from 3.25 ± 0.8 at baseline to 0.3 ± 0.7 medications at 12 months postoperatively in POAG eyes (p = 0.000; Wilcoxon test), and from 3.05 ± 1.0 to 0.3 ± 0.6 medications in PXG eyes (p = 0.000; Wilcoxon test). Hypotony (IOP ≤ 6 mmHg) was observed in 2 POAG eyes (3.0%) and in 5 PXG eyes (11.7%) at 1 month but normalized in all eyes at 12 months postoperatively. Severe complications were not observed. No statistically significant differences were found between PXG eyes and POAG eyes. CONCLUSION: Our data indicate that the XEN45 gel implant provides significant and comparable reduction in IOP and anti-glaucoma medication during the one-year follow-up period in POAG as well as PXG eyes. This suggests that it may be a noteworthy alternative to traditional filtering procedures in patients with POAG and PXG respectively.

Prospective, Non-randomized, 36-Month Study of Second-Generation Trabecular Micro-Bypass Stents with Phacoemulsification in Eyes with Various Types of Glaucoma.

INTRODUCTION: The aim of this study was to assess 36-month outcomes after cataract surgery and implantation of two second-generation trabecular micro-bypass stents (iStent inject, Glaukos Corporation, San Clemente, CA, USA) into eyes with predominantly primary open-angle glaucoma (POAG) or pseudoexfoliative glaucoma (PEX). METHODS: This prospective, non-randomized, consecutive cohort study included eyes with POAG (n = 60), PEX (n = 15), appositional narrow-angle (n = 4), pigmentary (n = 1), or neovascular (secondary) (n = 1) glaucoma and cataract requiring surgery. All eyes (n = 81) underwent ab interno iStent inject implantation following cataract surgery. Effectiveness endpoints through 36 months included intraocular pressure (IOP), number of medications, and proportion of eyes with ≥ 20% IOP reduction, IOP ≤ 18 mmHg, and IOP ≤ 15 mmHg. Safety measures included corrected distance visual acuity (CDVA), adverse events, and secondary surgeries. Outcomes were evaluated for the overall cohort, and for the POAG and PEX subgroups. RESULTS: Preoperatively, 32.1% of eyes had undergone prior glaucoma surgery, 56% were on 3-4 medications, and 1 eye (1%) was medication-free. At 36 months postoperatively, mean IOP reduced by 37% (14.3 ± 1.7 mmHg versus 22.6 ± 6.2 mmHg preoperatively), and mean medication burden decreased by 68% (0.8 ± 0.9 versus 2.5 ± 1.1 medications preoperatively). IOP reduced by ≥ 20% in 78% of eyes; 100% of eyes reached IOP ≤ 18 mmHg and 71% reached ≤ 15 mmHg. Medication burden reduced considerably: 22 eyes (54%) were medication-free compared to 1 eye (1%) preoperatively; 1 eye (2%) required ≥ 3 medications compared to 45 eyes (56%) preoperatively; and 92.7% of eyes required reduced medications postoperatively. From 3 through 36 months, mean IOP remained ≤ 15.0 mmHg, and mean number of medications remained ≤ 0.9. Outcomes in the POAG and PEX subgroups included 33% and 32% lower IOP, and 68% and 64% fewer medications, respectively. iStent inject showed a favorable safety profile, including no intraoperative complications, minimal adverse events, and a stable CDVA. CONCLUSION: This real-world cohort of eyes with various types of glaucoma and considerable disease burden exhibited durable and safe IOP and medication reductions through 36 months following iStent inject implantation with cataract surgery. Outcomes were similarly beneficial in eyes with POAG and PEX. FUNDING: Article processing charges were funded by Glaukos Corporation (San Clemente, CA, USA).

Standalone Ab Interno Gelatin Stent versus Trabeculectomy: Postoperative Interventions, Visual Outcomes, and Visits.

PURPOSE: To evaluate postoperative interventions, visual outcomes, and number of postoperative office visits after standalone ab interno gelatin microstent implantation with mitomycin C (MMC) vs. trabeculectomy with MMC. DESIGN: International, multicenter, retrospective cohort study. PARTICIPANTS: A total of 354 eyes of 293 patients, including 185 microstent eyes and 169 trabeculectomy eyes. METHODS: Consecutive eyes with uncontrolled glaucoma underwent microstent or trabeculectomy surgery from January 1, 2011, through July 31, 2015, at 4 academic ophthalmology centers: Toronto, Canada; Frankfurt, Germany; Salzburg, Austria; and Leuven, Belgium. MAIN OUTCOME MEASURES: Assessed outcomes included (1) in-clinic interventions, (2) transconjunctival needle revision (TCNR), (3) postoperative visits at 1 and 3 months, (4) >2 lines vision loss at last follow-up, (5) complete visual recovery, and (6) >0.5 or >1 diopter (D) of surgically induced astigmatism. RESULTS: Ninety-five (51.4%) of the microstent eyes and 105 (62.1%) of the trabeculectomy eyes underwent an intervention by last follow-up (log-rank P = 0.0004). The most common intervention was TCNR, followed by laser suture lysis. Seventy-eight (42.2%) microstent eyes and 55 (32.5%) trabeculectomy eyes received TCNR (adjusted hazard ratio [HR], 1.73 [95% confidence interval (CI), 1.10-2.71]): 128 total TCNRs in the microstent group and 95 in the trabeculectomy group. Predictors for TCNR included prior laser peripheral iridotomy and diabetes. Microstent eyes had on average 1.00 (standard deviation 2.32) fewer visits compared with trabeculectomy eyes in the first month (P < 0.001), adjusted for baseline characteristics. The percentage of eyes that had lost >2 lines of vision at last follow-up or reoperation was 12.4% (95% CI, 8.0%-18.7%) and was 21.9% (95% CI, 15.3%-30.1%) adjusted (P = 0.0383). A higher proportion of microstent eyes regained their baseline preoperative visual acuity compared with trabeculectomy eyes (log-rank P = 0.0250; adjusted HR, 1.46 [95% CI, 1.10-2.00]). Altogether, 25.3% (95% CI, 15.3%-38.9%) of microstent eyes and 40.7% (95% CI, 27.7%-55.3%) of trabeculectomy eyes had > 0.5 D surgically induced astigmatism on an adjusted basis; 8.0% (95% CI, 3.2%-18.6%) vs. 17.3% (95% CI, 8.9%-9.8%) had >1 D. CONCLUSIONS: Microstent eyes had more TCNRs (though fewer in-clinic interventions), fewer postoperative visits, and less vision loss, and experienced less surgically induced astigmatism, than trabeculectomy eyes. Overall, the postoperative course was less intensive for the microstent, except for more TCNRs.

Consecutive case series of 244 age-related macular degeneration patients undergoing implantation with an extended macular vision IOL.

PURPOSE: To determine safety and visual outcomes in eyes with age-related macular degeneration (AMD) implanted with a novel intraocular lens (IOL) that delivers an optimized retinal image to all macular areas within 10 degrees of retinal eccentricity. METHODS: This was a consecutive case series of 244 eyes with dry/stable wet AMD and logMAR visual acuity ≥0.3 implanted with iolAMD Eyemax monoTM (London Eye Hospital Pharma), a single-piece, injectable, hydrophobic acrylic IOL sited in the capsular bag. Primary outcome was safety. Secondary outcomes were changes in corrected distance visual acuity (CDVA) and corrected near visual acuity (CNVA) (logMAR). RESULTS: Mean age at surgery was 80 years. Mean duration of follow-up was 3 months (range 1-16 months). No eyes had worsening of CDVA. Frequency of perioperative complications was equivalent to standard IOL implantation. Postoperative refractive outcomes were within ±1 D of the target refraction in 88% of cases. Mean preoperative CDVA improved from 1.06 to 0.71 postoperatively (mean of differences -0.35; 95% confidence interval [CI] -0.3886 to -0.3223; p<0.0001), equating to an approximate Early Treatment Diabetic Retinopathy Study gain of 18 letters. Mean preoperative CNVA (N-point; logMAR conversion) improved from 1.36 to 0.88 postoperatively (mean of differences -0.48; 95% CI -0.53 to -0.44; p<0.0001). CONCLUSIONS: This novel IOL appears safe in the short to medium term. Improvements in postoperative CDVA and CNVA exceed those observed with standard implants.

Characteristics of Prostate Cancer Found at Fifth Screening in the European Randomized Study of Screening for Prostate Cancer Rotterdam: Can We Selectively Detect High-grade Prostate Cancer with Upfront Multivariable Risk Stratification and Magnetic Resonance Imaging?

BACKGROUND: The harm of screening (unnecessary biopsies and overdiagnosis) generally outweighs the benefit of reducing prostate cancer (PCa) mortality in men aged ≥70 yr. Patient selection for biopsy using risk stratification and magnetic resonance imaging (MRI) may improve this benefit-to-harm ratio. OBJECTIVE: To assess the potential of a risk-based strategy including MRI to selectively identify men aged ≥70 yr with high-grade PCa. DESIGN, SETTING, AND PARTICIPANTS: Three hundred and thirty-seven men with prostate-specific antigen ≥3.0 ng/ml at a fifth screening (71-75 yr) in the European Randomized study of Screening for Prostate Cancer Rotterdam were biopsied. One hundred and seventy-nine men received six-core transrectal ultrasound biopsy (TRUS-Bx), while 158 men received MRI, 12-core TRUS-Bx, and fusion TBx in case of Prostate Imaging Reporting and Data System ≥3 lesions. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was the overall, low-grade (Gleason Score 3+3) and high-grade (Gleason Score ≥ 3+4) PCa rate. Secondary outcome was the low- and high-grade PCa rate detected by six-core TRUS-Bx, 12-core TRUS-Bx, and MRI ± TBx. Tertiary outcome was the reduction of biopsies and low-grade PCa detection by upfront risk stratification with the Rotterdam Prostate Cancer Risk Calculator 4. RESULTS AND LIMITATIONS: Fifty-five percent of men were previously biopsied. The overall, low-grade, and high-grade PCa rates in biopsy naïve men were 48%, 27%, and 22%, respectively. In previously biopsied men these PCa rates were 25%, 20%, and 5%. Sextant TRUS-Bx, 12-core TRUS-Bx, and MRI ± TBx had a similar high-grade PCa rate (11%, 12%, and 11%) but a significantly different low-grade PCa rate (17%, 28%, and 7%). Rotterdam Prostate Cancer Risk Calculator 4-based stratification combined with 12-core TRUS-Bx ± MRI-TBx would have avoided 65% of biopsies and 68% of low-grade PCa while detecting an equal percentage of high-grade PCa (83%) compared with a TRUS-Bx all men approach (79%). CONCLUSIONS: After four repeated screens and ≥1 previous biopsies in half of men, a significant proportion of men aged ≥70 yr still harbor high-grade PCa. Upfront risk stratification and the combination of MRI and TRUS-Bx would have avoided two-thirds of biopsies and low-grade PCa diagnoses in our cohort, while maintaining the high-grade PCa detection of a TRUS-Bx all men approach. Further studies are needed to verify these results. PATIENT SUMMARY: Prostate cancer screening reduces mortality but is accompanied by unnecessary biopsies and overdiagnosis of nonaggressive tumors, especially in repeatedly screened elderly men. To tackle these drawbacks screening should consist of an upfront risk-assessment followed by magnetic resonance imaging and transrectal ultrasound-guided biopsy.

First Results of a New Hyperaspheric Add-on Intraocular Lens Approach Implanted in Pseudophakic Patients with Age-Related Macular Degeneration.

PURPOSE: To determine the visual outcomes of the EyeMax Mono intraocular lens (IOL) technology (London Eye Hospital Pharma, London, UK), which is a foldable and injectable hydrophobic acrylic IOL implanted as an add-on solution in pseudophakic eyes with age-related macular degeneration, in a pilot study. DESIGN: A prospective, interventional case series. PARTICIPANTS: A total of 22 pseudophakic eyes (11 patients) with bilateral severe or intermediate dry age-related macular degeneration (AMD) (13 eyes) or stable wet AMD or disciform scarring (9 eyes) meeting the criteria for sulcal IOL implantation. METHODS: Both eyes of participating subjects underwent small-incision ciliary sulcal implantation of a hyperaspheric, soft hydrophobic acrylic intraocular lens designed to improve the quality of the retinal image in all areas of the macula ≤10° from fixation and to generate a moderate hypermetropic correction for magnification. MAIN OUTCOME MEASURES: The primary outcome was safety as determined by intra- and postoperative complications, raised intraocular pressure requiring medical or surgical intervention, postoperative diplopia, reduction in visual field, and loss of ≥2 lines of visual acuity. Secondary outcomes were improvements in subjective and objective visual acuity (logarithm of the minimum angle of resolution). RESULTS: No intraoperative complication occurred. Elevated intraocular pressure values were measured directly after the operative procedure in 2 eyes (25 mmHg and 27 mmHg) and at the 1-week postoperative visit in 1 eye (22 mmHg) but not later. The mean postoperative spherical equivalent of refraction changed to +2.5 diopters, and all eyes had gained ≥2 lines of visual improvement (corrected distance visual acuity) by 6 months after surgery. Corrected near visual acuity as well as corrected distance visual acuity improved over time, suggesting a neuroadaptive component to improved visual function with the device. Devices were implanted bilaterally in all patients, and there were no reported symptoms of dysphotopsia or diplopia. CONCLUSIONS: Safety concerns were not identified in the short-term or medium term. These results indicate the potential of the EyeMax Mono IOL to improve near and distance visual acuity in pseudophakic eyes with intermediate to severe AMD.

[Pseudophacic additive lenses]. / Pseudophake additive Intraokularlinsen.

Implantation of artificial intraocular lenses (IOL) after cataract removal today represents the standard of care in the field of anterior segment surgery. In refractive lens exchange cases the natural lens is replaced by an IOL to correct different types of refractive situations. In the majority of the operations the refractive result is satisfying with only few deviations from target refraction.But daily practice reveals some outliers from the intended corrections with the need for further refractive enhancements, respectively. Especially odd eyes with short or long axial length, corneal astigmatism, ceratoconus or after corneal laser vision correction are more or less candidates for refractive surprises. Laser corneal surgery and additional intraocular implants are both established surgical approaches to achieve this goal in pseudophacic eyes. In paediatric cataract surgery for congenital cataracts implantation of add-on lenses can be helpful to adjust refraction according to eyeball development and prevent amblyopia.This article presents an overview about currently available implants and techniques using additional lenses to correct residual refractive errors. Furthermore, new implants for special indications like macular degeneration are addressed. A thorough evaluation of risk and benefit for each patient group and materials used are provided.

Femtosecond Laser-Assisted Capsulotomy: Histological Comparison of Four Different Laser Platforms.

PURPOSE: To compare histological analyses of capsulotomies from different laser systems with regard to tissue alteration, laser spot formation, and energy settings. METHODS: Four femtosecond laser platforms approved for cataract surgery were evaluated: LenSx (Alcon Laboratories, Inc., Fort Worth, TX), Catalys (Abbott Medical Optics, Santa Ana, CA), Victus (Tecnolas/Bausch & Lomb, Munich, Germany), and LensAR (Topcon, Gamagori, Japan). Ten human anterior lens capsulotomy disks from each laser system were analyzed: five by means of light microscopy and five by transmission electron microscopy (TEM). TEM was used especially to examine the cellular and stromal changes at the cutting edges. The cellular demarcation line was measured at 15 points along the rim and statistically compared with the findings from all laser platforms. Three capsules of each laser platform were prepared for TEM to evaluate the cellular and tissue edges of the laser cuttings. RESULTS: All capsulotomies revealed a circular demarcation zone of different sizes along the cutting edges. Light microscopy showed a radial tissue damage of 36.0 ± 12.3 µm after Victus laser capsulotomy, 8.9 ± 2.9 µm after Catalys laser capsulotomy, 25.2 ± 5.6 µm after LensAR laser capsulotomy, and 39.8 ± 5.1 µm after LenSx laser capsulotomy. Differences between the damaged tissue zones correlated with the laser systems and their energy settings. CONCLUSIONS: The use of less energy and larger spot separation led to smaller collateral damaged tissue areas along the cutting edges. The aberrant laser spots along the cutting edge may result in weakening of the remaining tissue, thereby enhancing the risk for capsular ruptures during surgery.

Ab Interno Gel Implant for the Treatment of Glaucoma Patients With or Without Prior Glaucoma Surgery: 1-Year Results.

PURPOSE: The purpose of this study is to evaluate IOP lowering effects and complication management of an ab interno gel implant for the treatment of patients refractory to antiglaucoma medication or glaucoma surgery. METHODS: Retrospective analysis of the medical records of 242 consecutive eyes of 146 patients with uncontrolled intraocular pressure (IOP) despite maximum tolerated medical therapy or prior surgical intervention that underwent XEN45 implantation (as sole procedure or in combination with cataract surgery) between March 2014 and June 2015. Data included IOP, number of glaucoma medications, the need for additional surgery, needling, and complications. RESULTS: During the study period, mean IOP had decreased by 54.1% from 32.19 (±9.1) mm Hg to 14.24 (±4.0) mm Hg (P=0.00; Wilcoxon test). The number of antiglaucoma medications had decreased from a mean of 3.13±1.0 to 0.3±0.7 (P=0.00; Wilcoxon test). Needling was required between week 1 and months 3 in 27.7% of all eyes to enhance the outflow. Hypotony (IOP<6 mm Hg) was observed in 9 eyes (4.0%) at 1 month but normalized in all eyes at 12 months postoperatively. Two eyes experienced hypotony requiring the refill of the anterior chamber. CONCLUSIONS: Our data indicate that the XEN45 gel implant has a favorable safety profile and is an effective treatment option for controlling IOP in glaucoma patients with unregulated IOP despite IOP lowering medical therapy or prior surgical intervention. It offers an effective approach, both as sole procedure and in combination with cataract surgery.
