Pars Plana Vitrectomy for Retained Lens Fragments After Cataract Surgery: Outcomes Based on Timing of Surgery. Clin Ophthalmol 2023; 17:479-485. [PMID: 36755889 PMCID: PMC9899933 DOI: 10.2147/opth.s391795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Accepted: 11/16/2022] [Indexed: 02/04/2023] Open
Abstract
Purpose To evaluate the outcomes and complications in patients with retained lens fragments (RLF) after cataract surgery, comparing those who received pars plana vitrectomy (PPV) on the same day, within 1 week, or later than 1 week after cataract surgery. Patients and Methods Retrospective case series of all patients who underwent PPV for RLF at Bascom Palmer Eye Institute between January 1, 2012 and September 30, 2020. Individuals with less than 3 months of follow-up, chronic uveitis, congenital cataract, previtrectomy retinal detachment (RD), and severe trauma were excluded. All analyses for categorical and binary variables used chi-squared tests. Analyses for continuous variables were performed using multivariate analyses of covariance, adjusting for differences in baseline visual acuity before cataract surgery. Results The study included 246 eyes of 246 patients. The timing distribution included the following: 140 (57%) eyes underwent same-day PPV, 33 (13%) eyes underwent same-week PPV, and 73 (30%) eyes underwent PPV after 1 week (up to 90 days). When all eyes were included in analysis, there were no statistically significant differences in mean best-corrected visual acuity (BCVA) between groups at last follow-up examination (P = 0.07). When only eyes without known pre-existing ocular disease (N = 157) were included in analysis, there were no differences in mean BCVA between groups at all postoperative timepoints (P > 0.05). The rate of RD did not differ between groups when eyes with and without pre-existing ocular disease were analyzed (P > 0.05). Conclusion In the current study, there were no statistically significant differences in postoperative BCVA or rates of RD at last follow-up examination in eyes undergoing PPV for RLF on the same day, within 1 week, or later than 1 week after cataract surgery.

Abstract
PURPOSE OF REVIEW Retained lens fragments are a relatively rare occurrence after cataract surgery. While no definite guidelines for the surgical management or timing of surgery of this complication exist, surgery is indicated for patients with large lens fragments, persistent inflammation, secondary glaucoma, corneal edema, retinal tears or detachments, and associated endophthalmitis. The aim of this review is to summarize the current surgical management of retained lens material. RECENT FINDINGS The Intelligent Research in Sight registry database of 2.26 million patients who underwent cataract surgery in the US indicated that 0.18% (1 in 563) had secondary removal of retained lens fragments in the anterior chamber in the operating room within 1 year of the original cataract surgery. The risk of returning to the operating room for retained lens material removal was greater among men, smokers, patients with Medicaid or military insurance, and those who had complex cataract surgery. Medical management with topical corticosteroids or observation may be considered for small lens fragments, but surgical removal remains the mainstay of the treatment for large lens fragments. SUMMARY Retained lens fragments following cataract surgery may result in various vision-threatening complications. Understanding the risk factors, diagnosis, and surgical management of retained lens fragments are critical to preserving good visual outcomes. Vitrectomy is effective in patients with posterior nuclear fragments, retinal detachment, endophthalmitis, or uncontrolled glaucoma not responding to medical management. The best timing for surgery for retained lens fragments should be further investigated in a prospective study.

Abstract
PURPOSE To evaluate and to compare functional outcomes and complication rates of the same-day versus delayed pars plana vitrectomy (PPV) for intravitreal retained lens fragments after cataract surgery. METHODS Retrospective comparative series of 135 eyes with retained lens fragments that underwent PPV between August 2014 and July 2016. Sixty-two eyes received same-day PPV (group 1) and seventy-three eyes underwent delayed PPV (group 2). Outcome measures included best-corrected visual acuity (BCVA) at 6 months and postoperative complications. RESULTS The mean time to PPV in group 2 was 4.3±5.3 days. Mean axial length, lens fragment size and surgical technique were comparable in both groups. At 6 months, BCVA was 0.27±0.40 logMAR in group 1, and 0.35±0.30 logMAR in group 2, with no significant difference (P=0.205). Fifty-one (82.2%) eyes in group 1 and 53 (72.6%) eyes in group 2 achieved BCVA of+0.30 logMAR (20/40) or better (P=0.183). The most common complications were macular edema, elevated intraocular pressure>25mmHg, and retinal detachment occurring respectively in 10 (16.1%) eyes, 4 (6.4%) eyes and one eye (1.6%) in group 1 and 11 (15.0%) eyes, 5 (6.8%) eyes and 2 (2.7%) eyes in group 2. Overall, the complication rate was similar in both groups (P=1). CONCLUSION Our study shows that visual acuity outcomes and complication rates were similar regardless of timing of the PPV. The optimal timing of surgery remains a multifactorial decision involving patient preferences, transportation, surgeon availability and severity of the initial presentation.

Abstract
TOPIC It is unclear whether differences exist in efficacy and safety between combined versus sequentially performed phacoemulsification and pars plana vitrectomy (phaco-PPV). CLINICAL RELEVANCE This meta-analysis aimed to compare the efficacy and incidence of complications between these surgical methods. METHODS Ovid MEDLINE, EMBASE, and Cochrane CENTRAL were searched for articles reporting the efficacy and safety of combined versus sequential phaco-PPV for any indication. The primary outcomes were postoperative best-corrected visual acuity (BCVA) and mean absolute refractive error from target (RET). Secondary outcomes included efficacy outcomes and postoperative complications. Meta-analysis was conducted using a random effects model in all cases. Risk of bias assessment was performed using the Cochrane risk of bias assessment tool for randomized trials and ROBINS-I tool for observational studies. RESULTS Of the 5410 articles identified, 1 randomized controlled trial and 14 comparative studies were included, with 1407 and 951 eyes in the combined and sequential surgery groups, respectively. Mean age was 62.71 ± 6.16 years and 44% (range, 32.1%-70%) of eyes were from men. The mean baseline BCVA was 0.88 ± 0.59 logarithm of the minimum angle of resolution units (Snellen equivalent, 20/152). The meta-analysis showed no significance between groups in postoperative mean BCVA (P = 0.76) and mean absolute RET (P = 0.46). The risks of synechiae formation (risk ratio [RR], 2.74; 95% confidence interval [CI], 1.83-4.11; P < 0.001), fibrin formation (RR, 2.81; 95% CI, 1.84-4.30; P < 0.001), and intraoperative or postoperative retinal detachment (RR, 2.65; 95% CI, 1.08-6.47; P = 0.03) were significantly higher after combined surgery. However, the risks of posterior capsular tear (RR, 0.43; 95% CI, 0.25-0.73; P = 0.002) and macular hole nonclosure or reopening (RR, 0.18; 95% CI, 0.03-0.93; P = 0.04) were significantly lower in the combined group. DISCUSSION No significant differences were found in visual and refractive outcomes between combined and sequential phaco-PPV, whereas differences existed in certain safety outcomes. These conclusions remain preliminary, as most evidence is derived from low- to moderate-quality retrospective studies. Given the variability in outcome reporting and associated heterogeneity, future randomized controlled trials are needed.

Abstract
AIM To evaluate the outcomes of "concurrent vitrectomy" to retrieve dislocated lens fragment during phacoemulsification. METHODS In a retrospective, observational case series, data of patients who underwent "concurrent" pars plana vitrectomy (PPV) for dislocated lens fragments between the period 2000 and 2008 were reviewed. Data collected included patient demographics, pre-operative visual acuity, intra-operative occurrence of retinal breaks, duration of follow up, post-operative intraocular pressure, final best-corrected visual acuity (BCVA), presence of cystoid macular edema (CME) and occurrence of rhegmatogenous retinal detachment (RRD). RESULTS A total of 58 eyes of 58 patients were included in the study. At 12mo the mean postoperative BCVA was logMAR 0.17 (20/30) with a range of logMAR 0 to 0.69 (20/20 to 20/100), with 96.6% (56/58) of patients showing post-operative improvement in visual acuity (P=0.005). None of the patients developed postoperative retinal detachment, endophthalmitis or non-resolving uveitis at 12mo. CONCLUSION Our study results suggest concurrent PPV for retained lens fragments after cataract surgery is beneficial and may decrease the risk of glaucoma and prevent development of RRD.

Abstract
Purpose/design We aimed to perform a systematic review and meta-analysis comparing the risk difference of clinical outcomes for same-day (SD) vs delayed (DEL) pars plana vitrectomy (PPV). Methods We searched MEDLINE (English; January 1, 1985 to July 16, 2013) and article reference lists, for patients with crystalline retained lens fragments and discussion of SD-PPV vs DEL-PPV. For the meta-analysis, articles needed the number of patients receiving SD-PPV and DEL-PPV, and the number, in each group, who experienced one or more of the outcomes: not good visual acuity (VA) (<20/40), bad VA (≤20/200), retinal detachment, increased intraocular pressure/glaucoma, intraocular infection/inflammation, cystoid macular edema, and corneal edema. Results Of 304 articles identified, 23 provided data for the meta-analysis. Results were mixed, indicating 1) neither vitrectomy time produced better outcomes in all studies (not good VA risk difference =10.3% [positive numbers favored SD-PPV; negative numbers favored DEL-PPV], 95% confidence interval [CI] = [−0.4% to 21.0%], P=0.059; and bad VA risk difference =−0.3%, 95% CI = [−10.7% to 10.1%], P=0.953); 2) better outcomes with immediate SD-PPV compared with all DEL-PPV (not good VA risk difference =16.2%, 95% CI = [0.8% to 31.5%], P=0.039; and bad VA risk difference =8.5%; 95% CI = [0.8% to 16.2%], P=0.030); and 3) immediate SD-PPV and prompt DEL-PPV (3 to 14 days after cataract surgery) had no significant differences and so may produce similar outcomes (not good VA risk differences range = [−19.9% to 6.5%], 95% CI = [−59.9% to 36.4%]; and bad VA risk differences range = [−6.9% to 7.4%], 95% CI = [−33.1% to 31.8%]). Conclusion Perhaps SD-PPV should be limited to facilities at which a vitreoretinal surgeon is immediately available. Otherwise, these results support referring a patient with retained lens fragments promptly to a vitreoretinal surgeon but do not support interfacility transport for SD-PPV.

Abstract
BACKGROUND AND OBJECTIVE To describe a technique of 25-gauge pars plana lensectomy with primary posterior capsulotomy and sparing of the anterior lens capsule that is suitable for all lens densities. PATIENTS AND METHODS The authors describe a technique they routinely employ for pars plana vitrectomy using primarily a 25-gauge, three-port approach with intraoperative lens density assessment and possible fragmatome use for dense lenses. An analysis of the ability to achieve surgical goals is provided. RESULTS Surgical goals were achieved in all 68 cases performed during an 18-month period. Anterior lens capsule was consistently spared, and 25-gauge fluidics functioned well even in the presence of a fragmatome and single 20-gauge sclerotomy. CONCLUSION 25-gauge pars plana lensectomy with vitrectomy with and without fragmatome incision is an efficacious technique for lensectomy.

Abstract
PURPOSE Intravitreal retained lens fragments are a rare but potentially serious complication of phacoemulsification. The purpose of this study was to compare same setting ("no wait") vitrectomy with delayed surgery in the management of retained lens fragments in a single academic setting. METHODS This study is a retrospective nonrandomized study of all patients undergoing pars plana vitrectomy for retained lens fragments after cataract surgery from 2007 to 2012. Outcomes included visual acuity and the development of various complications such as retinal detachment, elevated intraocular pressure >30 mmHg, and cystoid macular edema. Multivariate analysis was performed to adjust for potentially confounding variables such as age and preoperative visual acuity. RESULTS Twenty-eight consecutive eyes (13 same setting, 15 delayed setting) were included in the analysis. Patients in the same setting group were older than in the delayed group (81.00 vs. 72.87 years, P = 0.053). No other preoperative differences existed between the groups (axial length, preoperative vision, and intraocular pressure). The mean time to pars plana vitrectomy in the delayed group was 26.6 days (range, 1-91 days). The mean follow-up time was 363 days (same setting) and 643 days (delayed). At the most recent follow-up, no significant difference existed in mean vision between the same setting (logMAR, 0.42) and the delayed group (logMAR, 0.57) (P = 0.132). Multivariate analysis showed no difference in final vision when adjusting for age and preoperative vision. Although there was a trend for eyes in the same setting group to obtain good vision (≥ 20/40) faster, a higher percentage of eyes in the delayed group obtained good vision at the most recent follow-up (66.7 vs. 23.1%, P = 0.02). More eyes in the delayed group had an intraocular pressure >30 at any point (P = 0.055). There was no significant difference between the groups in any other complications such as retinal detachment, choroidal detachment, and cystoid macular edema during the follow-up. CONCLUSION In this cohort, same setting pars plana vitrectomy offers no significant visual acuity advantage over delayed pars plana vitrectomy in patients with retained lens fragments. Fewer eyes in the same setting group "ever" had an intraocular pressure ≥ 30 during follow-up, whereas no other complication differences were seen between the groups.

Abstract
PURPOSE OF REVIEW Posterior capsular rupture (PCR) is an infrequent complication of cataract surgery that can lead to significant ocular morbidity and permanent vision loss. In the setting of PCR, the primary objective is the safe and thorough evacuation of vitreous and lens fragments from the anterior segment. The secondary objective is the stable placement of an intraocular lens (IOL) selected for best refractive outcomes. Expedited referral to vitreoretinal specialists is recommended for management of posteriorly dislocated lens material and surveillance for retinal injury. It is the intention of this review to present current guidelines for the management of PCR. RECENT FINDINGS There are new techniques available to anterior and posterior segment surgeons in the setting of PCR. Endoillumination may facilitate visualization during anterior vitrectomy and the IOL may be used as a pupillary barrier to prevent loss of lens fragments. When secondary procedures are needed, early return to the operating room and small-gauge pars plana techniques may reduce patient morbidity. SUMMARY When approached carefully and systematically, patients may have good outcomes in the setting of PCR. Recent advancements in instrumentation and technique encourage further study and may lead to new standards of care.

Abstract
PURPOSE To compare visual acuity outcomes and adverse events in patients with retained lens fragments who underwent same-day versus later pars plana vitrectomy (PPV). DESIGN Retrospective, interventional case series. METHODS Single-center study evaluating all patients with retained lens fragments that underwent PPV over a 22-year period (1990 through 2011). RESULTS The study included 569 eyes of 568 patients with a mean age of 74.6 years and a median follow-up of 8 months (range, 1 week to 100 months). One hundred seventeen patients (22%) underwent same-day vitrectomy, 131 patients (23%) underwent PPV within 1 week, and 321 patients (57%) underwent PPV more than 1 week later. Median time to vitrectomy in the same week group was 5 days, compared with 22 days in the delayed group. At the last examination, 61%, 63%, and 56% of patients undergoing PPV on the same day, within 1 week, and more than 1 week later, respectively, achieved best-corrected visual acuity (BCVA) of 20/40 or better (P = .35), and 16%, 15%, and 21%, respectively, had BCVA of 20/200 or worse (P = .29). There were no differences between groups when assessing cystoid macular edema (P = .96), retinal detachment (P = .096), elevated intraocular pressure (P = .88), or suprachoroidal hemorrhage (P = .26). CONCLUSIONS Patients undergoing same-day versus a later PPV (within 1 week or more than 1 week later) for retained lens fragments had similar visual acuity outcomes and complication rates. Although same-day surgery may be attractive logistically in many cases, our retrospective data suggest equivalent outcomes for surgical timing.

Abstract
PURPOSE To evaluate the outcome and surgery-associated risks in patients undergoing 23-gauge pars plana vitrectomy (PPV) for retained lens fragments. METHODS Retrospective analysis of 42 eyes of 42 consecutive patients at a tertiary teaching hospital in Sydney (Australia) during a period of 4 years. Evaluation of final visual acuity, complications, differences in patients receiving an intraocular lens at the primary cataract surgery, and differences in final visual acuity regarding the usage of a phacofragmatome and analysis of pars plana vitrectomy-related complications. RESULTS The majority (83.3%) achieved a visual acuity of 0.3 (logarithm of the minimum angle of resolution) or better, and 19 eyes (45.2%) achieved a final visual acuity of 0 (logarithm of the minimum angle of resolution). Overall, 95.2% of the eyes had a better postoperative visual acuity compared with the preoperative visual acuity. There were no differences in proportions regarding the final visual acuity in patients who had an intraocular lens at the time of the pars plana vitrectomy and those who had a secondary lens implant. A retinal detachment after the lens fragment removal was observed in 2 eyes. CONCLUSION Dropped lens fragments because of complicated cataract surgery can be managed well with 23-gauge pars plana vitrectomy: The majority of patients achieve a good visual acuity despite 2 surgeries at a rather low rate of retinal complications.
