Abstract
INTRODUCTION The purpose of this study was to evaluate the clinical outcomes and quality of life of newly generated monofocal intraocular lens (IOL) in patients diagnosed with idiopathic epiretinal membrane (IEM) following phacovitrectomy. METHODS In this prospective study, 42 patients with IEM and cataract underwent pars plana vitrectomy. They were divided into the ICB00 group (21 patients) and the ZCB00 group (21 patients). Data collected before and after the surgery were compared between the two groups, including uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), vision-related quality of life (VRQOL), intraocular pressure, contrast sensitivity (CS), and central macular thickness (CMT). RESULTS The preoperative characteristics of the two groups showed no significant differences. However, at the 6-month follow-up after surgery, there were significant improvements in UDVA (p < 0.001), UIVA (p < 0.001), VRQOL (p < 0.001), CS (p < 0.001), and CMT (p < 0.001) compared to baseline. Notably, the Eyhance ICB00 group showed a significantly higher UCIVA value at 6 months post-surgery when compared to the Tecnis ZCB00 group (p = 0.001), while other parameters did not show significant differences between the groups. CONCLUSION The Eyhance IOL significantly improved both intermediate and distance visual acuity, with no notable difference in quality of life or CS compared to the Tecnis ZCB00 IOL after IEM removal. It appears to be a favorable choice for combined cataract and vitreoretinal surgery, offering enhanced vision for daily tasks and a promising alternative to traditional monofocal IOLs.

Diagnostics (Basel) 2024; 14:1483. [PMID: 39061620 PMCID: PMC11275800 DOI: 10.3390/diagnostics14141483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Revised: 07/02/2024] [Accepted: 07/06/2024] [Indexed: 07/28/2024] Open
Abstract
BACKGROUND The present study compares the anatomical and functional outcomes (best-corrected visual acuity (BCVA) and central macular thickness (CMT)) among membrane peeling with or without SF6 tamponade in patients with epiretinal membrane. METHODS We retrospectively reviewed patients diagnosed with macular pucker who underwent pars plana vitrectomy and membrane peeling in a tertiary center in Taiwan from January 2021 to December 2022. Subjects were categorized into with or without SF6 tamponade groups (SF6 group and BSS group). Postoperative intraocular pressure and complications were documented. Logistic regression analyses were performed to identify the prognostic factors during follow-up. RESULTS A total of 89 eyes were enrolled, including 34 eyes in the BSS group and 55 eyes in the SF6 group. The mean age was 66 years old, and a female predilection was demonstrated. Both groups possessed statistically significant improvement in BCVA and CMT after the operation. There was no significant difference in CMT between the groups at any time of observation, yet we observed significant differences in baseline BCVA and BCVA at last follow-up among the two groups. Both groups yielded an approximate enhancement of LogMAR 0.3 in BCVA postoperatively. There was no significant difference noted in postoperative IOP between the two groups. CONCLUSION Membrane peeling with or without SF6 tamponade yields comparable outcomes anatomically and functionally. This may indicate that SF6 tamponade for idiopathic macular pucker surgery may not provide extra benefit, and therefore warrants reconsideration as standard procedure.

Abstract
An epiretinal membrane (ERM) is a frequently occurring disease affecting the macula, which can be associated with visual impairment and metamorphopsia, depending on the severity and location. A distinction is made between an idiopathic form caused by age-related changes of the vitreous body and a secondary form associated with diseases of the posterior segment. The development of fibrocellular epiretinal membranes formed by dedifferentiation of intraretinal and extraretinal cells at the level of the vitreomacular interface plays a major role in the pathogenesis. The diagnostics and indications for surgical treatment of ERM are based on the visual acuity, evidence of metamorphopsia, ophthalmoscopic findings and optical coherence tomography (OCT) of the macula. In addition to the possibility of observation of the course where benign spontaneous courses are not uncommon, pars plana vitrectomy (PPV) with peeling of the ERM and internal limiting membrane (ILM) to prevent recurrences is the treatment of choice in symptomatic patients. The prognosis after surgical treatment is very good. In approximately two thirds of the cases, an improvement in visual acuity and/or a reduction of metamorphopsia can be achieved, with a number of predictive, primarily OCT-based factors enabling a prediction of the functional prognosis. Comprehensive patient education regarding the generally long duration of postoperative rehabilitation and the possibility of persistent symptoms or visual deterioration despite successful membrane removal is essential.

Abstract
BACKGROUND The effect of air tamponade among patients undergoing vitrectomy with membrane peeling for removal of epiretinal membranes (ERM) is controversially discussed. The aim of the present study was to analyze differences in outcomes between air tamponade and balanced salt solution (BSS) in a study population with preoperative intraretinal cystoid changes. PATIENTS AND METHODS This randomized study included patients scheduled for pars plana vitrectomy with membrane peeling owing to ERM and intraretinal cystoid changes. Air tamponade or BSS at the end of surgery was applied according to preoperative randomization. Optical coherence tomography and best-corrected distance visual acuity (DCVA) measurements were performed before surgery, 5 days after surgery, and 3 months after surgery. RESULTS From 96 patients included, 85 eyes had full follow-up and could be included for analysis. Median improvement of DCVA was + 16 EDTRS letters (IQR: 8 to 22) among patients with BSS, while it was + 13 EDTRS letters (IQR: 8 to 17) among patients with air tamponade. There was a trend for better improvement of DCVA when BSS was left at the end of surgery, compared to air tamponade, but not reaching statistical significance. CONCLUSIONS There were no statistically significant differences concerning resorption of preoperative intraretinal cystoid changes, improvement of visual acuity, and final DVCA between air tamponade and BSS.

Abstract
PURPOSE To evaluate the impact of different intraocular tamponades on the vision-related quality of life (VRQOL) after idiopathic epiretinal membrane (IEM) surgery with epiretinal membrane peeling. METHODS We prospectively enrolled 50 patients diagnosed with IEM who underwent pars plana vitrectomy. Patients were consecutively assigned to either the air tamponade (air) group (25 patients) or the balanced salt solution (BSS) tamponade group (25 patients). The following data were collected before and after surgery and compared between the two groups: VRQOL, best-corrected visual acuity, intraocular pressure, metamorphopsia, contrast sensitivity, and central macular thickness. RESULTS Pars plana vitrectomy was performed in 50 eyes. At baseline, there were no significant differences between the two groups. At 6 months postoperatively, VRQOL ( P < 0.001), best-corrected visual acuity ( P < 0.001), central macular thickness ( P < 0.001), contrast sensitivity ( P < 0.001), and metamorphopsia ( P < 0.001) improved significantly in comparison with baseline, without significant differences between the air tamponade and BSS groups. CONCLUSION Removing IEM significantly improved visual function and VRQOL. Despite improvements, this study showed no difference postoperatively whether air or BSS tamponade was used during surgery. As a result, air tamponade may not be a mandatory treatment for IEM surgery and provides no additional advantage compared with BSS tamponade.

Abstract
This study aimed to compare the surgical outcomes of pars plana vitrectomy (PPV) with and without air tamponade in patients with idiopathic epiretinal membrane (iERM). We prospectively enrolled 145 patients with iERM who underwent a 25-gauge transconjunctival sutureless PPV. Patients were assigned to either the air tamponade (air) group (79 eyes) or balanced salt solution (BSS; no tamponade) group (66 eyes). The central macular thickness (CMT), peripapillary retinal nerve fiber layer (pRNFL) thickness, and best-corrected visual acuity (BCVA) were compared for two years. At baseline, there were no significant differences between the two groups. CMT and BCVA were not significantly different between the groups for 2 years. However, the air group had a significantly lower thickness in the superior temporal pRNFL sector at 1 month (p = 0.01) and in the inferior temporal and superior temporal pRNFL sectors at 3 months (p = 0.02 for both). There were no significant differences between both groups in all the pRNFL sectors from 6 months to 2 years. The outcomes of PPV with air tamponade and that with no tamponade appear to be equivalent. This shows that air tamponade may not be an imperative procedure for iERM surgery and has no additional benefit.

Abstract
PURPOSE Epiretinal membrane is a macular disorder leading to metamorphopsia and decreased visual acuity. The aim of the present study was to assess the possible effects of air tamponade, balanced salt solution (BSS), and combined phacoemulsification on functional and anatomical outcomes. PROCEDURES This prospective exploratory analysis included 72 eyes with idiopathic epiretinal membranes, scheduled to undergo 23-G pars plana vitrectomy with membrane peeling. Air tamponade or BSS was used in all cases. Optical coherence tomography (OCT) imaging was performed intraoperatively, and follow-up including visual acuity testing and OCT measurements was conducted until 3 months postoperatively. RESULTS Mean best-corrected visual acuity improved between +2.1 and +3.1 letters, and mean central subfield thickness of the macula decreased between -29.6 and -76 µm in the examined groups, without significant differences between the air tamponade and BSS groups. There was no significant difference in the presence of intraretinal cystoid changes between the groups. CONCLUSIONS The use of air tamponade did not show any significant differences in the anatomical and functional postoperative results compared to BSS. Furthermore, phacovitrectomy did not result in significantly more intraretinal cystoid changes 3 months after surgery.

Abstract
PURPOSE Epiretinal membranes (ERM) are macular disorders leading to loss of vision and metamorphopsia. Vitrectomy with membrane peeling displays the gold standard of care. Aim of this study was to assess risk factors for postoperative intraretinal cystoid changes in a study population randomized for balanced salt solution and air-tamponade at the end of surgery. METHODS A prospective randomized study, including 69 eyes with idiopathic ERM. Standard 23-gauge three-port pars plana vitrectomy with membrane peeling, using intraoperative optical coherence tomography (OCT), was performed. Randomization for BSS and air-tamponade was performed prior to surgery. RESULTS Best-corrected visual acuity improved from 32.9 letters to 45.1 letters 3 months after surgery. Presence of preoperative intraretinal cystoid changes was found to be the only risk factor for presence of postoperative intraretinal cystoid changes 3 months after surgery (p = 0.01; odds ratio: 8.0). Other possible risk factors such as combined phacoemulsification with 23G-ppv and membrane peeling (p = 0.16; odds ratio: 2.4), intraoperative subfoveal hyporeflective zones (p = 0.23; odds ratio: 2.6), age over 70 years (p = 0.29; odds ratio: 0.5) and air-tamponade (p = 0.59; odds ratio: 1.5) were not found to be significant. CONCLUSION There is strong evidence that preoperative intraretinal cystoid changes lead to smaller benefit from surgery.

Abstract
To evaluate the refractive outcomes of balanced salt solution infiltration during small-incision lenticule extraction (SMILE).This randomized prospective study enrolled 52 patients (104 eyes) with myopic astigmatism. Patients underwent SMILE to correct the myopic astigmatism in Daping Hospital of the Third Military Medical University between January and July 2013. One eye of each patient received traditional SMILE (control group) and the other received a modified SMILE procedure (liquid infiltration group). The corrected distance visual acuity (CDVA), postoperative uncorrected distance visual acuity (UDVA), refraction, wavefront aberration, intraocular pressure (IOP), modulation transfer function (MTF) cut-off frequency, and objective scattering index (OSI) were evaluated.UDVA in the liquid infiltration group was significantly higher than that in the control group at 1 day postoperatively, but not at 1 month after surgery. Moreover, OSI and MTF cut-off frequency in the liquid infiltration group were higher than those in the control group at early follow-up. However, no significant intergroup difference was observed in the OSI and MTF cut-off frequency at 3 months after surgery. In addition, the predictability was better in the liquid infiltration group than in the control group. The changes of horizontal coma in the liquid infiltration group were lesser than those in the control group. However, no intergroup difference was observed in the reduction of IOP at 1 month after surgery.The modified SMILE procedure results in better visual outcomes than did the traditional SMILE procedure when used for treating myopic astigmatism.

Abstract
Purpose. To assess functional and morphological alterations following video-documented surgery for epiretinal membranes. Methods. Forty-two patients underwent video-documented 23-gauge vitrectomy with peeling of epiretinal (ERM) and inner limiting membrane (ILM). Patient assessment was performed before and 3 and 6 months including best corrected visual acuity (BCVA), slit lamp biomicroscopy, SD-OCT, and central 2° and 18° microperimetry. In addition, all video-documented areas of peeling on the retinal surface were evaluated postoperatively using an additional focal 2° microperimetry. Retinal sensitivity and BCVA were correlated with morphological changes (EZ and ELM) in the foveal region and in regions of membrane peeling. Results. Overall, BCVA increased from 0.6 (±0.2) to 0.2 (±0.2) logMAR after 6 months with an increase in retinal sensitivity (17.9 ± 2.7 dB to 26.8 ± 3.1 dB, p < 0.01). We observed a significant correlation between the integrity of the EZ but not of the ELM and the retinal sensitivity, overall and in peeling areas (p < 0.05). However, no significant correlation between alterations in the area of peeling and overall retinal sensitivity regarding visual acuity gain could be observed after 6 months (p > 0.05). In contrast, overall postoperative retinal sensitivity was significantly decreased in patients with a visual acuity gain lower than 2 lines (p < 0.05) correlating with EZ defects seen in OCT. Conclusions. Mechanical trauma of epiretinal membrane and ILM peeling due to the use of intraocular forceps may affect the outer retinal structure. Nevertheless, these changes seem to have no significant impact on postoperative functional outcome.
