Acta Ophthalmol 2024; 102:e352-e357. [PMID: 37681397 DOI: 10.1111/aos.15760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 08/03/2023] [Accepted: 08/29/2023] [Indexed: 09/09/2023]
Abstract
PURPOSE To evaluate the influence of topical short-acting mydriatics on the formation of posterior synechia after phacovitrectomy surgery of pars plana vitrectomy and phacoemulsification with intraocular lens implantation. METHODS A prospective randomised controlled trial. Fifty-seven adult (>18 years old) patients (57 eyes) who underwent phacovitrectomy surgery at a single tertiary hospital, were randomly divided into two groups. The control group (29 eyes) received standard postoperative treatment (topical antibiotics and steroids). The study group (28 eyes) received short-acting mydriatics together with standard therapy. Patients were followed until 24 months after surgery. The primary outcome measure was the formation of posterior synechia during the follow-up period. RESULTS A total of 7 patients developed posterior synechia during the follow-up period (12%), 3 in the study group (11%) and 4 in the control group (14%). There was no statistical difference between the groups. Significant associations for the development of posterior synechia were surgery for retinal detachment, longer surgery duration (>93 min) and the use of tamponade, in particular silicone oil. CONCLUSIONS The use of topical short-acting mydriatic drops after phacovitrectomy surgery, in addition to standard post-operative treatment, did not reduce the formation of posterior synechia. However, we identified several factors that may influence or act as predictors for the development of posterior synechia: surgery for retinal detachment, using silicone oil tamponade and a longer surgery duration. Our findings may aid in the standardisation of post-phacovitrectomy surgery treatment and define potential at-risk patients who should be monitored more closely.

[PMID: 36879221 PMCID: PMC9987054 DOI: 10.1186/s12886-023-02818-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Accepted: 02/15/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND To quantitatively investigate corneal changes and the correlation between corneal densitometry (CD) and endothelial parameters after phacovitrectomy. METHODS Thirty-eight eyes with idiopathic full-thickness macular holes (iFTMHs) and cataracts underwent phacovitrectomy. Examinations were conducted at baseline and Day 1, Day 7, Month 1, and Month 3 postoperatively. CD and central corneal thickness (CCT) were measured using Pentacam. Corneal endothelial cell density (ECD), coefficient of variation (CV), and hexagonality (HEX) were measured using specular microscopy. RESULTS ECD and HEX significantly decreased after surgery and the change in HEX occurred prior to CV. CCT increased immediately after surgery and recovered 3 months postoperatively. CD values increased significantly 1 day after surgery and then gradually decreased. For CD in the 0-2 mm zone, it took 1 month to recover in the central and posterior layers and 3 months in the anterior and total layers. For CD in the 2-6 mm zone, the central layer recovered at Day 7, the anterior and total layers recovered at 1 month, and the posterior layer did not recover until 3 months postoperatively. The CD within all layers in the 0-2 mm zone was positively correlated with CCT. Posterior CD in the 0-2 mm zone was negatively correlated with ECD and HEX. CONCLUSIONS CD is not only correlated with CCT, ECD, and HEX but also reflects the state of the whole cornea and each layer. CD can be an objective, rapid, and noninvasive tool that reflects corneal health and undetectable edema and monitors the process of lesion repair. TRIAL REGISTRATION This study was registered with the Chinese Clinical Trial Registry (31/10/2021, ChiCTR2100052554).

Abstract
PURPOSE To investigate factors associated with refractive outcomes after phacovitrectomy for epiretinal membrane (ERM). METHODS Retrospective review of patients undergoing phacovitrectomy for ERM was done. The main outcome measure was predictive refraction error (PE), defined as observed refraction error - target refraction error, calculated by the SRK/T, Haigis, and SRK II formulae. PE was measured at postoperative 1, 3, and 6 months. Simple and multiple linear regression analysis were used to evaluate factors associated with PE. RESULTS A total of 53 eyes of 53 patients were included. The mean PEs at postoperative 1, 3, and 6 months were all negative, implying myopic shift in all patients regardless of the intraocular lens formula used. Haigis formula showed the least myopic shift among the three formulae (p = 0.001, Friedman test). There was no significant difference in PE depending on preoperative central macular thickness (CMT) in subgroup analysis. On stepwise multiple linear regression analysis, ERM etiology (β = 0.759, p = 0.004, SRK/T formula; β = 0.733, p = 0.008, Haigis formula; β = 0.933, p < 0.001, SRK II formula), preoperative anterior chamber depth (β = -0.662, p = 0.013, Haigis formula; β = -0.747, p = 0.003, SRK II formula), and decrease of CMT (β = -0.003, p = 0.025, SRK/T formula) were significantly associated with PE at postoperative 6 months. CONCLUSIONS Myopic shift in PE was observed after combined phacovitrectomy for epiretinal membrane. ERM etiology, preoperative anterior chamber depth, and decrease of CMT were significantly associated with PE at postoperative 6 months. There was no difference in PE after surgery between the two groups defined by CMT (≥500 and <500 μm).

Abstract
Purpose To evaluate the safety and clinical outcomes of combined phacoemulsification with intraocular lens (IOL) placement and microincision vitrectomy surgery (MIVS) in adult patients with concomitant cataract and vitreoretinal disease. Methods A consecutive series of patients with comorbid vitreoretinal disease and cataract who had combined phacoemulsification with IOL placement and MIVS was retrospectively analyzed. The main outcome measures were visual acuity (VA) and intraoperative and postoperative complications. Results The analysis comprised 648 eyes of 611 patients. The median follow-up was 26.9 months (range, 12-60 months). The most common vitreoretinal pathology was intraocular tumor (53%). The best-corrected Snellen VA improved from 20/192 at baseline to 20/46 at the 12-month follow-up. The most frequent intraoperative complication was capsule tear (3.9%). The most common postoperative adverse events after 3 months of follow-up (mean, 24 months) were vitreous hemorrhage (3.2%) and retinal detachment (1.8%). No patient developed endophthalmitis. Conclusions Combined phacoemulsification with IOL placement and MIVS is a safe, effective technique to manage a broad range of vitreoretinal diseases in patients with significant cataract.

Clinical Application of Foldable Capsular Vitreous Bodies in the Treatment of Severe Ocular Trauma and Silicone Oil Dependent Eyes. J Ophthalmol 2022; 2022:3608162. [PMID: 36339727 PMCID: PMC9635962 DOI: 10.1155/2022/3608162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 09/18/2022] [Accepted: 09/28/2022] [Indexed: 11/18/2022] Open
Abstract
Purpose This study aimed to assess the application of a foldable capsular vitreous body (FCVB) in the treatment of severe ocular trauma and silicone oil (SO) dependent eyes. Methods A retrospective analysis was performed on the clinical application of FCVB in the treatment of severe ocular trauma and SO dependent eyes. The results of best-corrected visual acuity and intraocular pressure (IOP) evaluation, B-scan ultrasonography or color Doppler ultrasonography, ultrasound biomicroscopy, and anterior segment photography were recorded during follow-up. A paired t-test was used to compare the difference in IOP before and after FCVB implantation. Results Seven eyes of seven patients were included in the 6-month follow-up. In all cases, B-scan ultrasonography and ultrasound biomicroscopy showed that FCVB adapted closely to the globe wall and ciliary body, thus supporting the retina. Visual acuity did not improve, except in one case from LP to HM. The mean ± SD IOP was 8.5 ± 1.90 mm·Hg prior to FCVB implantation and 10.43 ± 0.98 mm·Hg after implantation, with no significant difference between these measurements (P=0.095). Five of the seven patients developed differing degrees of corneal opacity and keratopathy. Conclusions FCVB implantation may be a safe and effective method for the treatment of severe ocular trauma and SO dependent eyes. However, FCVB cannot prevent the phthisis of the traumatic eyes. In addition, corneal opacity and keratopathy are potentially serious complications after surgery. Appropriate case selection and proper surgical timing are required for further investigation.

Abstract
PURPOSE To compare functional and anatomic outcomes of combined pars plana vitrectomy (PPV) and phacoemulsification (phaco) versus PPV and deferred phaco in patients with full-thickness macular hole (FTMH) and no significant cataract. METHODS Thirty-four patients were randomized to group 1 (combined PPV/phaco) and 34 to group 2 (PPV/deferred phaco). Group 2 patients could undergo phaco any time after FTMH surgery if significant cataract developed. RESULTS Sixty-five patients (33 group 1 and 32 group 2) completed the 12-month visit. Mean ± SEM logMAR best-corrected visual acuity (BCVA) was 0.92 ± 0.04 and 0.90 ± 0.04 at baseline and improved significantly to 0.60 ± 0.05 and 0.58 ± 0.05 at month 12 (p < 0.0001) in groups 1 and 2, respectively. There was no significant difference between the groups in mean BCVA at baseline or at month 12. Mean macular sensitivity (dB) was 18.22 ± 0.93 and 16.72 ± 0.93 at baseline and increased to 21.13 ± 0.86 and 21.07 ± 0.85 in groups 1 and 2, respectively (p < 0.05) with no significant difference between the groups (p = 0.449) at month 12. FTMH closure rate was 73% and 75% in groups 1 and 2, respectively (p = 0.834). CONCLUSION Among patients with FTMH and no significant cataract at baseline, combined PPV/phaco was associated with similar BCVA, microperimetry, and FTMH closure outcomes at 1-year compared with PPV/deferred phaco.

Abstract
BACKGROUND To investigate the accuracy of preoperative biometry in eyes undergoing combined phacovitrectomy and to compare it with eyes having cataract surgery at a later point in time following vitrectomy. METHODS Patients with epiretinal membrane or macular hole who underwent combined phacovitrectomy (group 1) or phacoemulsification following pars plana vitrectomy (PPV) (group 2) were included in this retrospective, comparative, interventional case series. The primary outcome measures were the intraocular lens power prediction error (PE) and the percentage of eyes with PE > ± 0.5D in the two groups. Secondary outcome measures included the correlation between epidemiological, clinical, or surgical factors and dioptric shift. In addition, the influence of optical coherence tomography characteristics to the PE was investigated. RESULTS Group 1 and 2 consisted of 55 and 54 eyes, respectively, for a total of 109 eyes included in the study. The mean absolute PE was 0.59 D (range + 1.4 to - 2.5D) in group 1 and 0.35 (range + 1.0 to - 1.45D) in group 2 (p = 0.01). PE greater than 0.5D was observed in 47% of eyes in group 1 as opposed to 16.6% of eyes in group 2 (p = 0.027). The PE was associated with shallower anterior chamber depth (ACD), increased central macular thickness (> 300 μ), and worse baseline best-corrected visual acuity. Photoreceptor ellipsoid zone or external limiting membrane disruption was not associated with significantly greater postoperative refractive deviations. CONCLUSION Combined phacovitrectomy may result in greater postoperative refractive prediction error compared to phacoemulsification alone following vitrectomy. Patients with worse vision, greater central macular thickness, and shallow anterior chambers require more caution since they are prone to inaccurate preoperative biometry.

Abstract
PURPOSE To evaluate light and electron microscopic changes of the anterior capsule and its epithelium after clear lens extraction of vitrectomized myopic eyes with silicone oil tamponade. METHODS This prospective, controlled, non-randomized, interventional study included 20 anterior lens capsular specimens that were excised during combined clear lens extraction and silicone oil removal from previously vitrectomized highly myopic patients with silicone oil tamponade for previous retinal detachment surgeries. The specimens were examined via light microscopy and electron microscopy and compared with 20 anterior capsule specimens removed during clear lens extraction of non-vitrectomized highly myopic eyes. RESULTS Light microscopic examination of clear lens anterior capsule specimens of vitrectomized myopic eyes filled with silicone oil showed relatively more flat cells with irregular outline of lens' epithelial cells with wide intercellular spaces, deeply stained nuclei, and multiple intracytoplasmic vacuoles. Scanning electron microscopy revealed collagenous surfaces filled with multiple pits, depressions, and abnormal deposits. Transmission electron microscopy revealed lens epithelial cells with apoptotic changes, many cytoplasmic vacuoles, and filopodia-like protrusions between lens epithelial cells and the capsule. Epithelial proliferation and multilayering were also observed. CONCLUSION silicone oil may play a role in the development of apoptotic and histopathological changes in clear lens epithelial cells. Clarity of the lens at the time of silicone oil removal does not indicate an absence of cataractous changes. We found justification of combined clear lens extraction and silicone oil removal or combined phacovitrectomy when silicone oil injection is planned, but further long-term studies with larger patient groups are required.

Abstract
PURPOSE To compare 1.8 mm micro-incision and 2.75 mm standard incision in coaxial cataract surgery combined with 23-Gauge (23G) vitrectomy with respect to intraoperative and postoperative complications and outcomes. METHODS In this prospective study 30 eyes of 30 patients planned for combined phacoemulsification and 23G vitrectomy were enrolled, and randomized to undergo either Standard 2.75 mm Incision Cataract Surgery (SICS, 15 eyes) or Coaxial 1.8 mm Micro-Incision Cataract Surgery (C-MICS, 15 eyes) followed by vitrectomy. Inclusion criteria were cataract and macular disorders including macular hole, epiretinal membrane and vitreomacular traction. Data were collected at preoperative evaluation and 1 and 12 months or more after surgery. RESULTS Incision leakage occurred in two eyes (7%: one per group), retinal break in nine (30%: four in C-MICS, five in SICS). Fibrin in anterior chamber (AC) occurred day 1 in three eyes (10%: two C- and one SICS). Posterior capsule opacification developed in 22 eyes (78%: 13 MICS, nine SICS, p = 0.1). A myopic shift of -0.63 ± 0.7 was noted (-0.59 ± 0.8 MICS, -0.68 ± 0.6 SICS, p = 0.74). Surgically induced astigmatism (SIA) was significantly smaller in C-MICS group (ΔKP, -0.019 ± 0.095 versus -0.141 ± 0.219, p = 0.0038) at 1 month but not at final follow-up (ΔKP, 0.0005 ± 0.16 in C-MICS versus -0.057 ± 0.12, p = 0.3 CONCLUSIONS: Both techniques were equally safe with respect to intraoperative and postoperative findings. Coaxial micro-incision cataract surgery (C-MICS) was associated with less surgically-induced astigmatism (SIA) 1 month after surgery but differences were not statistically significant at final follow-up indicating a faster refractive recovery with C-MICS than with SICS.

Abstract
PURPOSE This study was initiated to investigate whether the presence of macular oedema influenced intraocular lens (IOL) power calculation in eyes with epiretinal membrane. METHODS The files of patients undergoing combined phacoemulsification were retrospectively reviewed. Two groups were defined according to presence of macular oedema. The main outcome measure was the IOL power prediction error (PE). Secondary outcome measures were the correlation between preoperative macular thickness, absolute change of macular thickness and dioptric shift. The mean postoperative PE achieved with the Haigis formula was compared with the PE that would have been obtained had the SRKII and HofferQ formulas been used. RESULTS We investigated 47 eyes of 47 consecutive patients. Regardless of the IOL formula used, the PE was on average higher in eyes without macula oedema (group 1). The myopic dioptric shift was dependent on preoperative macular thickness and absolute change of macular thickness. This association was more markedly pronounced in group 1. CONCLUSIONS Increased retinal thickness is the main cause for underestimation of the cornea-photoreceptor layer distance, and therefore could contribute to inaccuracy in IOL power calculations. The current results show that a myopic shift tends to be less pronounced in cases where a macula oedema is present. Eyes with pure traction have less predictable refractive results in terms of higher PE and dioptric shift.

Abstract
PURPOSE To study the efficacy of a single 0.7 mg dexamethasone intravitreal implant in vitrectomized eyes with refractory macular edema secondary to combined cataract extraction and macular pucker removal. METHODS In 8 eyes of 8 consecutive patients with refractory macular edema secondary to combined cataract extraction and 25-gauge vitrectomy with internal limiting membrane peeling for macular pucker removal, the injection of the 0.7 mg dexamethasone implant was performed. Best-corrected visual acuity, central retinal thickness measured by spectral domain optical coherence tomography, and intraocular pressure were evaluated at baseline, 1 month, and 6 months. RESULTS After a mean follow-up of 6.75 ± 0.71 months, best-corrected visual acuity was significantly increased (P < 0.0001) from 20/50 to 20/23 (P < 0.0001), mean central retinal thickness decreased significantly from 439 ± 45 μm to 296 ± 49 μm (P < 0.0001), and intraocular pressure changed significantly (P = 0.02) from 14.63 ± 1.19 to 16 ± 0.93. In no case postoperative hypotony or other complication was observed. CONCLUSION A single injection of the 0.7 mg dexamethasone intravitreal implant resulted effective in the treatment of refractory macular edema secondary to combined cataract extraction and vitrectomy for macular pucker removal allowing a stable visual acuity recovery.

Abstract
BACKGROUND The aim of this study was to assess the safety and surgical results of femtosecond laser-assisted phacovitrectomy. METHODS A retrospective analysis of the medical records of patients over 50 years of age with vitreoretinal pathology, who had undergone pars plana vitrectomy using 23-gauge instruments and femtosecond laser-assisted cataract surgery and implantation of an intraocular lens, was performed at the Instituto de Microcirugía Ocular between June 2012 and September 2013. The diameter of the anterior capsulorhexis was set at 4.8 mm in cases where a gas tamponade was used and at 5 mm in all other cases. During the pars plana vitrectomy, posterior capsulotomy was performed on all eyes. An assessment was carried out of preoperative characteristics, surgical indications, postoperative results and complications. Only patients with a minimum of 3 months of follow-up were included. RESULTS A total of 21 eyes in 21 patients (71.4% women) were treated. Mean age (± SD) was 65.8 ± 6.4 years (range 53-76). The most common indication for surgery was epiretinal membrane (61.9%), followed by vitreous haemorrhage (23.8%) and macular hole (14.3%). The mean preoperative best corrected visual acuity (BCVA) was 0.81 ± 1.01 logMAR and the mean postoperative BCVA was 0.12 ± 0.19 logMAR (p = 0.003). 85.7% of patients improved their visual acuity. The remaining patients maintained their visual acuity. The only intraoperative complication related to femtosecond laser was 1 case of suction loss (4.8%). A patient with rhegmatogenous retinal detachment discovered during surgery required an additional circular scleral procedure and developed synechiaes in the early postoperative period (<1 month). There were no cases of subluxation of the intraocular lens. Mean follow-up was 6 months (range 3-14). CONCLUSIONS The application of femtosecond laser in phacovitrectomy is a safe and effective technique that presents advantages compared to conventional techniques in cases of macular pathology and/or vitreous haemorrhage.

Abstract
BACKGROUND/AIMS 23-gauge pars plana vitrectomy (ppv) is a new method for vitreo-retinal surgery. It may reduce operation time, the risk of complications, and patient discomfort, especially in combination with simultaneous bimanual microincisional cataract surgery (b-MICS). METHODS Seventy-five consecutive patients who underwent combined cataract surgery and ppv at our center between 1 January 2008 and 31 December 2010 were included. The first 36 patients were treated with 20-gauge ppv, the following 39 patients with 23-gauge ppv. Study end points 8 weeks after surgery were duration of the procedure, improvement of visual acuity, and occurrence of complications. RESULTS Duration of surgery was reduced in 23- vs 20-gauge ppv (54.0 ± 11.6 vs 61.0 ± 19.0 min, P=0.08). Visual acuity improved significantly in both the groups (20-gauge: logMAR 0.750 ± 0.304 before and 0.369 ± 0.273 after surgery; 23-gauge: logMAR 0.663 ± 0.340 before and 0.339 ± 0.273 after surgery). There were no appreciable group differences in baseline or post-treatment visual acuity. CONCLUSIONS 23-gauge ppv in combination with b-MICS is a suitable, safe, and effective method for the treatment of combined cataract and vitreo-retinal diseases. The procedure is somewhat shorter and patient discomfort during and after surgery is improved. In terms of efficacy and safety, 23-gauge ppv is equivalent with conventional 20-gauge ppv.

Abstract
Purpose. To evaluate early and late postoperative anterior segment complications of phacovitrectomy and foldable intraocular lens (IOL) implantation in eyes with cataract and coexisting vitreoretinal disease in diabetic and nondiabetic patients. Setting. Department of Ophthalmology, Baskent University Hospital, Ankara, Turkey. Methods. The records of 189 consecutive patients with cataract and posterior segment pathology necessitating phacovitrectomy were retrospectively analyzed. Patient profile, indications for surgery, preoperative findings, intraoperative and postoperative course, and postoperative outcome were evaluated. Phacoemulsification was performed through a clear corneal incision with IOL implantation prior to 23-G pars plana vitrectomy. Results. There were 97 (51.3%) diabetic and 92 (48.6%) nondiabetic patients. The most common indications for surgery were vitreous hemorrhage (57; 58.7%), tractional detachment (35; 36%), and premacular hemorrhage (5; 5.1%) in diabetic patients, and rhegmatogenous retinal detachment (40; 43.4%), macular hole (22; 23.9%), epiretinal membrane (20; 21.7%), and vitreomacular traction (10; 10.8%) in nondiabetic patients. Early (within 4 weeks) postoperative complications included elevation of intraocular pressure, fibrinous uveitis, corneal edema, and development of posterior synechia. Long-term (after 4 weeks) complications included migration of silicone oil into the anterior chamber, posterior capsule opacification, and decentered IOL. The ratio of fibrinous uveitis, posterior synechia, and posterior capsule opacification was found higher in the diabetic group (all p<0.05). Conclusions. Combined vitreoretinal surgery and phacoemulsification is safe and effective in treating vitreoretinal abnormalities coexisting with cataract in diabetic and nondiabetic patients. Diabetic patients should be monitored more carefully for fibrinous uveitis and posterior synechia in the early postoperative period and for posterior capsular opacification in the late postoperative period.

Abstract
Background The purpose of this study was to evaluate the incidence and amount of macular edema by optical coherence tomography (OCT) after combined small gauge sutureless vitrectomy with phacoemulsification and intravitreal triamcinolone. Methods This retrospective case series included 194 consecutive eyes undergoing nonemergent vitrectomy with phacoemulsification and intravitreal triamcinolone. Ninety-one eyes had preoperative and postoperative OCT available and were included in the analysis. The eyes were evaluated for retinal thickness with preoperative and postoperative OCT, and for preoperative and postoperative best-corrected visual acuity. The main outcome measures were retinal thickness, OCT appearance, and best-corrected visual acuity. Results The incidence of macular edema in all eyes preoperatively was 64.8% and postoperatively was 50.5%. Mean central subfield and center point thickness in eyes with macular edema preoperatively were 361 μm and 349 μm, respectively, and postoperatively were 315 μm and 304 μm, respectively. In eyes without preoperative macular edema, mean preoperative central subfield and center point thickness were, respectively, 210 μm and 181 μm versus 220 μm and 192 μm postoperatively. Best corrected visual acuity improved from 20/190 preoperatively to 20/150 at postoperative month 1 and 20/110 at month 6. Postoperative intraocular pressure ≥ 25 mmHg was observed in 7.7% of eyes, none of which required surgical intervention for steroid-induced glaucoma. Conclusion Use of intravitreal triamcinolone with combined vitrectomy and phacoemulsification may play an important role in modulating postoperative macular edema. Adverse pressure rise is infrequent and usually limited.

Abstract
Lens extraction during vitrectomy is sometimes necessary to obtain an adequate view of the retina. Currently, phacoemulsification through a clear corneal incision with implantation of a foldable intraocular lens has become the preferred technique for cataract extraction during pars plana vitrectomy. The authors described the technique of lensectomy using a bimanual microincisional cataract surgery technique during pars plana vitrectomy and insertion of the intraocular lens at the end of surgery, which has several advantages over conventional coaxial phacoemulsification procedures.

Abstract
PURPOSE To evaluate the effect of the blue light-filter intraocular lenses (IOLs) in vitrectomy combined with cataract surgery, focusing on the surgeon's ability to perform specific vitreoretinal procedures and on the patients' outcome. DESIGN Randomized clinical trial. METHODS Sixty patients, recruited from our outpatient department, were assigned randomly to receive an ultraviolet-filter IOL (clear IOL group) or a blue light-filter IOL (yellow IOL group) combined with a vitreoretinal procedure. Main outcome measures were intraoperative conditions for the surgeon and the functional outcome. Second outcome measures were complication rates and vitreoretinal diagnoses. RESULTS The questionnaire responses showed that the blue light-filter IOLs did not represent an impediment to vitreoretinal surgery (P>.05). No intraoperative complications were encountered in either group. Patients in both IOL groups showed comparable functional results with respect to visual acuity, contrast sensitivity, color vision, and glare effect (P>.05). The functional outcome was influenced significantly by the vitreoretinal diagnosis (P<.01). CONCLUSIONS With the possible advantage of macular protection and no intraoperative or functional disadvantage, the routine use of the blue light-filter IOL in combined surgery can be recommended.

Abstract
PURPOSE To assess the efficacy and safety of bimanual microphacoemulsification combined with vitrectomy in eyes with clinically evident cataract and vitreoretinal pathology. SETTING Institute of Ophthalmology of the University of Modena and Reggio Emilia, Modena, Italy. METHODS This prospective case series comprised 19 consecutive patients with clinically significant cataract who were scheduled for vitrectomy. Bimanual microphacoemulsification was performed, and an Acri. Smart 46 S hydrophobic acrylic intraocular lens (IOL) with a 6.0 mm optic (Acri.Tec, Inc.) was implanted in the capsular bag. Immediately after, standard 3-port vitrectomy was performed. RESULTS The prevailing vitreoretinal pathology was retinal detachment, with 1 case of macular pucker and 1 case of macular hole. In all cases, the IOL was implanted in the capsular bag. There were no intraoperative complications during the cataract surgery or vitrectomy. Follow-up 1, 15, 30, 90, and 180 days after surgery showed significant visual recovery in all cases. The mean endothelial loss was 10.05%+/-2.01% (SD). In 3 cases that had tamponade with heavy silicone oil, progressive posterior capsule opacification occurred 6 months after surgery. CONCLUSIONS Bimanual microphacoemulsification combined with vitrectomy was effective and safe. The microincisions and 19-gauge instruments provided excellent chamber resistance that simplified surgical maneuvers in eyes that might have a distorted fundus reflection and increased zonular laxity. The Acri. Smart 46 S IOL, which can be injected through a 2.0 mm incision, provided good fundus visibility during vitrectomy and good maneuverability up to the extreme periphery without resulting in glare or distracting reflections for the surgeon.

Abstract
PURPOSE Evaluate the use of an ophthalmic endoscope in patients with a retinal detachment and anterior media opacity. MATERIALS AND METHODS A retrospective interventional case series. Search of a comprehensive database of retinal detachment patients with pre-operatively impaired anterior segments such that lens extraction, a keratoprosthesis, or extensive anterior segment manipulation was required for adequate repair. Pars plana vitrectomy was carried out with an endoscope without manipulation of the anterior segment. Characteristics of the detachment were recorded, as were complications/subsequent surgeries, pre-operative, 3-month post-operative, and final follow-up visual acuities. RESULTS Before surgery, five patients had a gas-induced cataract after a failed pneumatic retinopexy; one patient had a Reis-Buckler's dystrophy and corneal ulcer; three patients had synechiae around iris-fixed lenses. One patient had proliferative vitreoretinopathy. The median pre-operative vision was hand motion (20/30 to light perception). The median final visual acuity was 20/30 (20/20-20/200). Two patients required a subsequent lens extraction, one patient had a recurrent detachment. CONCLUSION In appropriate retinal detachment patients, endoscopy can be safe and effective, while limiting the scope of the surgical intervention.
