[PUBLICATION TRENDS AND IMPACT OF OPHTHALMOLOGY DEPARTMENTS IN ISRAEL: SUMMARIZING OVER A DECADE OF RESEARCH WITH AN INTERNATIONAL PERSPECTIVE (2011-2021)].

BACKGROUND: A focused bibliographic analysis of Israel's ophthalmology research productivity has never been performed. OBJECTIVES: To assess the research output of Israeli ophthalmology departments between the years 2011-2021 and compare to leading countries in the discipline. METHODS: The PubMed search engine was used to detect all medical articles published between the years 2011 and 2021, with at least one author from an Israeli ophthalmology department. Each entry was reviewed for: year of publication, journal, department, sub-specialty, and study design. Journals were ranked according to Scopus Cite Score. Research output and population data of 7 top-ranked countries in ophthalmology (USA, UK, Japan, Germany, Australia, Canada, China) were documented for comparisons. RESULTS: Overall, 1,919 publications were included. Total research output of Israeli ophthalmology departments significantly increased throughout the study period (R2=0.85, P<0.0001). Medical retina publications were the most prevalent (493 articles, 25.6%), and the most commonly utilized design was cohort (536 articles, 28%). Over a third of all articles (669) were published in Q1 ophthalmology journals, and 16% were published in the top-10 journals. Israel was ranked (1/8) and (3/8) in publications per population and physician, respectively, compared to the other assessed countries. CONCLUSIONS: Between 2011-2021, the research productivity of the Israeli ophthalmological community has constantly increased across all sub-specialties and in high-impact journals. Israel's relative contribution to the ophthalmic medical literature is noteworthy internationally.

The 100 Most-Cited Articles on Optic Neuritis: Trends of Subtypes, Authorship, and Time.

BACKGROUND: Optic neuritis (ON) is an optic nerve inflammation that may lead to different degrees of vision loss. In recent decades, ON research facilitated a better understanding of the disease and its subtypes. This bibliometric analysis aimed to detect the 100 most-cited medical articles related to ON in the last 50 years (1972-2021) and describe publication trends arising from the list. METHODS: The Scopus database was used to locate and screen the 100 most influential ON papers based on the number of citations per article. Each entry was reviewed for the first author (name, gender, institution, and country), year of publication, journal, number of citations, ON subtype, and study design. The mean impact factor (IF) of each journal was calculated. RESULTS: The median number of citations was 265 (range 182-2,396). Observational studies on neuromyelitis optica-associated ON were the most common (27%), and the most influential decade was 2002-2011 (54 papers). Seventy-nine percent of articles were published in neurology journals, and a positive correlation between the mean number of citations per article and the journal mean IF was observed ( r = 0.62, P < 0.001). Between 2009 and 2021, female authors led more ON studies (52%), and more publications originated outside the USA (68%), compared with previous years. CONCLUSIONS: This analysis summarizes the impact and shifting trends of ON research in the last decades.

Effects of delay in anti-vascular endothelial growth factor intravitreal injections for neovascular age-related macular degeneration.

PURPOSE: To assess the impact of COVID-19-related delay in intravitreal injection timing on macular structure and visual acuity (VA) among patients treated for neovascular age-related macular degeneration (nvAMD). METHODS: We reviewed demographic and clinical data and macular ocular computerized tomographic images of 34 patients (48 eyes, group A) who did not follow their injection schedule during the first wave of COVID-19 and compared them to 46 patients (71 eyes, group B) who did. Functional worsening was defined as a loss of at least 0.1 in decimal VA. Anatomic worsening was defined as new or increased subretinal/intraretinal fluids or new hemorrhage. RESULTS: The planned mean ± standard deviation intervals between the intravitreal injections were 5.7 ± 2.7 weeks for group A and 5.5 ± 2.4 weeks for group B (P = 0.60). The actual intervals were 13.6 ± 6.8 (7.9 ± 5.2 weeks' delay) and 5.3 ± 2.4 weeks (no delay), respectively (P < 0.001). The best corrected visual acuity worsened in 23 group A eyes (47.9%) and in 6 group B eyes (8.5%) (odds ratio [OR] 9.97, P < 0.001). Anatomic features indicative of nvAMD worsening were detected in 31 group A eyes (64.6%) and in 16 group B eyes (22.5%) (OR 5.73, P < 0.001). A new macular hemorrhage was observed in 4 group A eyes (8.3%) and in no group B eyes (P = 0.09). CONCLUSION: Delay in timely retinal care during the COVID-19 restrictions period resulted in short-term negative outcomes, including macular bleeding, in nvAMD patients.

Anxiety and pain perception using a speculum-free eyelid retraction technique for intravitreal injection.

PURPOSE: This study compared pain and anxiety levels in individuals receiving intravitreal injections (IVIs) using a speculum-free injection technique, the lid splinting eyelid retraction technique, or using a speculum. METHODS: This was a prospective study of individuals receiving IVI at a single tertiary care medical center who responded to a questionnaire and visual analog scale (VAS) between December 2019 and January 2020. In one group, a speculum was used prior to injection, whereas in the other group, a speculum-free injection technique was used. RESULTS: A total of 108 individuals were included in this study: 54 received IVI with the speculum-free lid splinting eyelid retraction technique and 54 received IVI with a speculum. A correlation between pain and anxiety was demonstrated in the control group (p-value < 0.01); however, in the speculum-free group, this correlation was lower and not significant. When comparing pain and anxiety between the study groups, lower median pain (Mood's: Z = 5.378, p-value < 0.001) and lower anxiety (Mood's: Z = 2.108, p-value = 0.035) scores were demonstrated in the speculum-free group than in the control group. The distribution of pain scores was significantly different between the study groups (Kolmogorov-Smirnov: D = 0.518, p-value < 0.001), and trending differences in anxiety between the groups were observed (Kolmogorov-Smirnov: D = 0.259, p-value = 0.053). CONCLUSION: The lid splinting eyelid retraction technique, a speculum-free technique, was associated with less anxiety and pain in patients than the use of a speculum. As IVI often involves repeated treatment, identifying modifiable factors that may relieve anxiety and pain is of utmost importance.

Interface Fluid Syndrome 2 Decades After Laser-Assisted In situ Keratomileusis.

PURPOSE: To report a case of late-onset interface fluid syndrome (IFS) after laser-assisted in situ keratomileusis (LASIK). METHODS: A 94-year-old man was referred for evaluation because of persistent corneal edema 10 days after Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) for pseudophakic bullous keratopathy. RESULTS: After an uneventful DSAEK, the patient was treated with topical antibiotics and steroids. On presentation, a well positioned and oriented DSAEK graft was observed in the right eye, yet the cornea was edematous. Applanation tonometry was normal. Anterior-segment optical coherence tomography (AS-OCT) revealed a LASIK flap with a fluid cleft beneath it. Requery confirmed that LASIK was performed 21 years ago. Topical steroids were stopped, and after 2 weeks, the cornea was clear, and AS-OCT revealed complete resolution of the interface fluid. CONCLUSIONS: Even decades later, IFS should be considered as a source of corneal edema in patients after LASIK. Monitoring these patients with AS-OCT is recommended.

Pediatric Ocular Injury Due to Hand Sanitizer Exposure: An Emerging Hazard.

OBJECTIVES: The objective of this study was to describe the incidence and severity of ocular exposure to alcohol-based hand rub (ABHR) in children presenting to a tertiary medical center during the severe acute respiratory syndrome coronavirus 2 pandemic. METHODS: A retrospective single-center observational study conducted from February 21, 2020, to October 11, 2020. Subjects 10 years or younger who presented with ABHR-induced ocular injury were included. The same period from 2019 was studied and a comparison was performed between the 2 years. Outcome measures included the number of subjects with ocular injury due to ABHR, extent of ocular epithelial defects, length of hospitalization and time to resolution. RESULTS: A total of 9 patients presented to the Pediatric Emergency Department after sustaining ocular chemical injuries from ABHR during this period. Treatment included immediate irrigation followed by topical antibiotics, steroids, and lubrication. Six children were discharged and followed as outpatients with no reported adverse ocular sequelae. Three patients exhibited epithelial defects involving 85% to 100% of the cornea, 30% to 75% of the conjunctiva and required inpatient treatment ranging from 4 to 11 days. All patients experienced a complete resolution of the ocular epithelial defects after 12 to 19 days. No long-term irreversible damage was observed and visual acuity returned to normal in all patients. CONCLUSIONS: The utilization of ABHR during the severe acute respiratory syndrome coronavirus 2 pandemic resulted in childhood ocular injury. Prompt treatment led to good visual outcomes. These products should be regarded as potentially toxic and stored out of the reach of young children.

Response of ophthalmologists in Israel to the novel coronavirus (2019-nCoV) outbreak.

PURPOSE: The coronavirus disease (COVID-19) pandemic has evolved into a formidable healthcare crisis. Ophthalmologists are at daily personal risk of acquiring and transmitting the virus. Implementation of official practical and protective guidelines can be challenging and is often absent. The purpose of this study was to describe the status of ophthalmology practice in Israel, at the early stages of the outbreak. METHODS: A 17-item questionnaire was distributed to ophthalmologists practicing in Israel. Data was obtained regarding demographics and clinical and surgical practice during the pandemic. RESULTS: One hundred and sixty-seven ophthalmologists completed the survey from all regions of Israel. The survey was distributed during the early stages of the outbreak. At this time, no official government guidelines were in place. Most respondents reported no reduction of elective clinic visits and surgeries and no utilization of triage questionnaires. COVID-19 guidelines were reportedly promulgated to hospital ophthalmologists but not to community and private physicians. Personal protective equipment (PPE) measures were reportedly utilized; however, many respondents often acquired them individually. A majority of respondents advocated that healthcare institutions limit clinic and surgery services to emergency services. CONCLUSION: During the critical early stages of the COVID-19 outbreak in Israel, this study emphasizes the delay in development of emergency guidelines, necessary to protect patients and ophthalmologists from this highly transmissible disease.

Management of labor after external cephalic version.

OBJECTIVES: Current literature evaluating the role of induction of labor (IOL) following successful external cephalic version (ECV) attempt as compared to expectant management is limited. We aim to assess the risk of cesarean delivery in those undergoing immediate IOL following successful ECV as compared to those who were expectantly managed. METHODS: A retrospective cohort study of successful external cephalic versions. The study group included 57 women that were induced after procedure in the lack of maternal or fetal indications for induction of labor. These women were compared to 341 expectantly managed women. Maternal and fetal characteristics and outcomes were compared. RESULTS: Gestation age at delivery was higher among the expectant management group (401/7 vs. 384/7, median, p=0.002) as compared to the induction group. Cesarean delivery rates were similar between both groups (28 [8.2%] vs. 3 [5.3%], p=0.44). In a multivariate logistic regression analysis, only nulliparity was significantly associated with cesarean delivery (adjusted odds ratio 3.42, confidence interval 1.61-7.24, p=0.001). No correlation was found between the version-to-delivery interval and the risk for cesarean delivery. CONCLUSIONS: Induction of labor after successful ECV was not shown to influence cesarean delivery rates. As immediate IOL may result in higher rate of early-term deliveries, and in light of the lack of clinical benefit, we advocate against elective IOL following successful ECV.

Successful vaginal delivery after external cephalic version (ECV): does time interval from ECV to delivery make a difference? A multicenter study.

PURPOSE: The risk of cesarean delivery after a successful external cephalic version for breech presentation is higher as compared with fetuses in cephalic presentation. However, the role of the time interval between version attempt to delivery on the risk for cesarean delivery is unclear. We aimed to study the effect of the time interval from a successful external cephalic version to delivery on the risk for cesarean delivery and assess factors associated with cesarean delivery after a successful version. METHODS: We conducted a multicenter, retrospective cohort study, including all successful external cephalic version at two medical centers between 2011 and 2019. We compared patient baseline characteristics, obstetric characteristics, maternal and neonatal outcomes in women that delivered by vaginal delivery with those who delivered by cesarean delivery. RESULTS: Overall, 769 deliveries were included. Of these, 98 women (12.7%) had cesarean delivery and 671 (87.3%) had vaginal delivery. Women who had cesarean delivery had a higher rate of obesity (44.9% vs 21.9%, p < 0.001; OR 2.88, CI 1.65-5.03) and nulliparity (45.9% vs 24.5%, p < 0.001; OR = 2.58, CI 1.67-3.98). The risk for intrapartum cesarean delivery did not differ according to time interval from external cephalic version to delivery. CONCLUSIONS: The time interval between successful external cephalic version and delivery was not associated with mode of delivery. This finding is in contrast to previous reports. The risk for cesarean delivery after successful version is higher in nulliparous, obese women, and women whose weight gain in pregnancy was higher.

Macular Ganglion Cell Complex and Peripapillary Retinal Nerve Fiber Layer Thinning in Patients with Type-1 Gaucher Disease.

Type-1 Gaucher disease (GD1) is considered to be non- neuronopathic however recent evidence of neurological involvement continues to accumulate. There is limited evidence of retinal abnormalities in GD1. The purpose of this study was to evaluate the retinal findings of patients with GD1. Thirty GD1 individuals and 30 healthy volunteers between the ages 40-75 years were prospectively enrolled. Macular and optic nerve optical coherence tomography (OCT) scans of both eyes of each patient were performed and thickness maps were compared between groups. Patients with a known neurodegenerative disease, glaucoma, high myopia and previous intraocular surgeries were excluded. It was shown that patients with GD1 presented with higher incidence of abnormal pRNFL OCT scan and showed significantly thinner areas of pRNFL and macular ganglion cell complex (GCC) when compared to a healthy control population. Changes in retinal thickness were not associated with GD1 genotype, treatment status, disease monitoring biomarker (lyso-Gb1) and severity score index (Zimran SSI). Further investigations are needed to determine whether these findings possess functional visual implications and if retinal thinning may serve as biomarker for the development of future neurodegenerative disease in this population.

External cephalic version at term: A 6-year single-operator experience.

BACKGROUND: External cephalic version (ECV) should be offered for patients presenting with a noncephalic pregnancy that are willing to deliver vaginally. Various reports have evaluated predictors for successful ECV. Yet, none have reported a single-operator large cohort experience. We aim to analyze the outcome of referrals for ECV. METHODS: We conducted a retrospective cohort study of prospectively collected data. We performed a multivariate analysis of data with respect to ECV procedures performed by a single operator in a 6-year period. Maternal and fetal characteristics were compared between ECV success and failure groups. RESULTS: Six hundred and two women underwent ECV. Of them, ECV was successful in 432 (71.7%). A multivariate binary logistic regression model demonstrated that high liquor volume was a predictor of ECV success (Adj OR 1.17 [95% CI 1.09-1.26]). Failure of ECV was correlated with anterior placenta (0.44 [0.56-0.76]) and nulliparity (0.21 [0.11-0.36]). Adverse events were rare and mostly minor, occurring in 1% of procedures. CONCLUSIONS: ECV has a high success rate and a low complication rate, enabling vaginal birth and avoiding cesarean. The role of manipulation of modifiable determinants such as liquor volume should be further assessed in future studies.

Late preterm versus term external cephalic version: an audit of a single obstetrician experience.

PURPOSE: Recent literature evaluating the optimal timing for external cephalic version (ECV) in non-cephalic presentation is limited and hampered by methodological issues. We aimed to compare late preterm ECV [term (36-37 weeks of gestation] to term ECV ( > 37 weeks). METHODS: We conducted a retrospective cohort study of prospectively collected data of ECV procedures performed by a single operator during a 6 year period. Maternal, ECV procedure, delivery and fetal characteristics were compared between preterm ECV and term ECV. RESULTS: Overall, 547 (91.6%) of ECVs were term ECV while 50 (8.4%) procedures were preterm ECV. Success rate of ECV was 72.0% in the preterm ECV group vs. 71.5% in the term ECV group, p = 0.93. Proportion of preterm delivery was higher among the preterm ECV group (8% vs. 0%, p < 0.001), so does the proportion of early term deliveries (36.0% vs. 22.8%, p = 0.03). The rate of low birth weight was higher among the preterm ECV group (10.0% vs. 3.11%, p = 0.01). Rates of Apgar score at 5 min ≤ 8 were higher in the preterm ECV (4.0% vs. 0.5%, p = 0.007). Vaginal delivery and intrapartum cesarean delivery rates did not differ between study groups (72.0% vs. 73.2%, p = 0.83 and 10% vs. 8.4%, p = 0.69). CONCLUSION: Initiating ECV before term is associated with increased rate of preterm delivery, early term delivery and low birth weight. No effect was found in mode of delivery, intrapartum cesarean delivery, reversion and spontaneous version. We advocate against preterm ECV until future prospective trials will better delineate the effect of preterm ECV on maternal and neonatal outcomes.

Vitreous hemorrhage as an early sign of acute bacterial endophthalmitis following intravitreal ranibizumab injection.

PURPOSE: To report a case of acute bacterial endophthalmitis after antivascular endothelial growth factor injection with a rare presentation of vitreous hemorrhage. METHODS: An 84-year-old woman presented with sudden painless vision loss in her left eye, 3 days after intravitreal ranibizumab injection for cystoid macular edema due to neovascular age-related macular degeneration. The patient was otherwise asymptomatic. Dense vitreous hemorrhage was observed. At follow-up the next day, the patient complained on severe left eye pain. After examination, acute endophthalmitis was diagnosed. RESULTS: Intravitreal injection of vancomycin, ceftazidime and dexamethasone was performed. Vitreous and aqueous cultures grew Enterococcus faecalis. After treatment, the inflammation subsided but it took 3 months for the vitreous hemorrhage to totally resorb. Visual acuity was reduced to light perception. CONCLUSIONS: Vitreous hemorrhage may be an atypical presentation of acute bacterial endophthalmitis occurring after intravitreal injection.

The efficacy and safety of external cephalic version after a previous caesarean delivery.

BACKGROUND: External cephalic version (ECV) in the presence of a uterine scar is still considered a relative contraindication despite encouraging studies of the efficacy and safety of this procedure. We present our experience with this patient population, which is the largest cohort published to date. AIMS: To evaluate the efficacy and safety of ECV in the setting of a prior caesarean delivery. MATERIALS AND METHODS: A total of 158 patients with a fetus presenting as breech, who had an unscarred uterus, had an ECV performed. Similarly, 158 patients with a fetus presenting as breech, and who had undergone a prior caesarean delivery also underwent an ECV. Outcomes were compared. RESULTS: ECV was successfully performed in 136/158 (86.1%) patients in the control group. Of these patients, 6/136 (4.4%) delivered by caesarean delivery. In the study group, 117/158 (74.1%) patients had a successful ECV performed. Of these patients, 12/117 (10.3%) delivered by caesarean delivery. There were no significant complications in either of the groups. CONCLUSIONS: ECV may be successfully performed in patients with a previous caesarean delivery. It is associated with a high success rate, and is not associated with an increase in complications.

Exploring the Accuracy and Readability of ChatGPT in Providing Information to Patients With Keratoconus.

Patients with keratoconus may lack sufficient understanding of their illness. The authors assessed the accuracy and readability of ChatGPT (OpenAI) responses to common questions regarding keratoconus and found that the provided data are precise, with minor inaccuracies. The complexity of responses requires a high reading level, which may be unsuitable for many patients. [J Pediatr Ophthalmol Strabismus. 2024;61(5):e43-e46.].

Optimizing axial length measurement success in advanced cataract patients through pupil dilation.

PURPOSE: To evaluate the impact of pharmacologic pupil dilation on axial length (AL) measurement in patients with dense cataracts and previous failed AL measurements carried out without pupil dilation. DESIGN: Retrospective case series. METHODS: All participants underwent swept-source optical coherence tomography (SS-OCT) biometry. Patients with unsuccessful AL measurements due to dense cataract underwent an additional SS-OCT biometric evaluation after pupil dilation, and the SS-OCT AL measurement was compared to the immersion ultrasound. RESULTS: The study included 3668 eyes of 3668 patients who underwent SS-OCT between October 2021 and March 2023. Of them, 102 eyes (2.8%) had failed AL measurements because of dense cataract. Eighty-seven of those 102 eyes underwent a repeat SS-OCT biometric exam following pharmacologic pupil dilation, after which AL measurements were successfully achieved in 27 (31.0%) of the 87 eyes. These measurements were found to be consistent with immersion ultrasound, supporting the validity of SS-OCT biometer measurements post dilation. CONCLUSIONS: Pharmacologic pupil dilation improved the rate of successful SS-OCT biometrically measured AL in patients with failed AL measurement due to dense cataract.

Refining glaucoma diagnosis and treatment in cataract surgery candidates: contribution of preoperative OCT retinal nerve fiber layer.

PURPOSE: To evaluate the clinical significance of preoperative spectral domain optical coherence tomography (OCT) of the retinal nerve fiber layer (RNFL) thickness in identifying glaucoma and better managing patients scheduled for routine cataract surgery. SETTING: Department of Ophthalmology, Shaare Zedek Medical Center, Jerusalem, Israel. DESIGN: Retrospective cohort study. METHODS: Consecutive patients scheduled for cataract surgery were enrolled from February 2022 to August 2022. Participants underwent routine OCT RNFL studies which were evaluated by a glaucoma specialist. Findings were compared with those of preoperative fundus biomicroscopic examinations conducted by the referring ophthalmologist. The main outcomes were the incidence of newly detected glaucoma based on OCT RNFL findings and the consequent changes in patient management. RESULTS: In total, 486 patients met the inclusion criteria of whom 112 (23%) had abnormal RNFL. 31 patients (6.4%) had abnormal OCT RNFL findings attributed to comorbidities other than glaucoma, and 81 patients (16.7%) were suspected to have glaucoma based on their OCT RNFL findings, from which 44 patients (9%) were newly diagnosed with glaucoma or as glaucoma suspects, resulting in management modifications that included routine glaucoma follow-up (25 patients, 5.1%), initiation of intraocular pressure-lowering treatment (12 patients, 2.5%), and conversion to combined cataract-glaucoma surgery (7 patients, 1.4%). CONCLUSIONS: OCT RNFL for cataract surgery candidates proved valuable in detecting glaucoma that had not been revealed by standard fundus biomicroscopic examination. The additional information provided by OCT RNFL can potentially enhance patient management and optimize outcomes.

Clinical Outcomes of Transscleral-Sutured Intraocular Lens Combined With Descemet Membrane Endothelial Keratoplasty.

PURPOSE: The aim of the study was to report clinical outcomes of Descemet membrane endothelial keratoplasty (DMEK) combined with transscleral-sutured intraocular lens (IOL) compared with DMEK combined with phacoemulsification and posterior chamber IOL (Phaco-DMEK). METHODS: A retrospective chart review of all patients who underwent DMEK combined with transscleral-sutured intraocular lens fixation or combined with phacoemulsification for Fuchs endothelial corneal dystrophy from 2016 to 2021 at the Toronto Western Hospital or the Kensington Eye Institute (Toronto, ON, Canada) and had at least 18 months of follow-up was performed. Main outcomes were postoperative distance-corrected visual acuity, rebubbling rate, graft survival rate, and complications. RESULTS: Twenty-one cases of DMEK combined with transscleral-sutured IOL (DMEK-TSS-IOL) and 44 cases of Phaco-DMEK were evaluated. Twelve eyes (57.15%) had a foldable acrylic 3-piece IOL (AR40E) and 9 (42.85%) had a single-piece polymethylmethacrylate (PMMA) IOL (CZ70BD). LogMAR distance-corrected visual acuity improved significantly from 1.48 ± 0.62 (SD) to 0.86 ± 0.82 ( P = 0.01) 12 months after DMEK-TSS-IOL and from 0.41 ± 0.29 logMAR to 0.11 ± 0.11 logMAR ( P < 0.0001) after Phaco-DMEK. No statistically significant differences were observed in donor ( P = 0.97) or 1-year postoperative endothelial cell density ( P = 0.11) between the groups. Rebubbling was necessary in 33.33% of eyes in DMEK-TSS-IOL compared with 25% of Phaco-DMEK eyes ( P = 0.55). Graft survival rate was 76.19% in the DMEK-TSS-IOL group compared with 90.90% in the Phaco-DMEK group ( P = 0.13). CONCLUSIONS: Transscleral-sutured IOL combined with DMEK is an option for the management of endothelial diseases in aphakic eyes or those which require IOL exchange for the experienced surgeon. However, when compared with routine Phaco-DMEK, there are higher complication and lower survival rates at 18 months.

Early Impact of Laser Vision Correction (LVC) on the Stability and Quality of the Retinal Image.

This retrospective comparative study analyzes the early postoperative impact of laser vision correction for myopia on the optical quality and stability of functional vision using a double-pass aberrometer. Retinal image quality and visual function stability were assessed preoperatively, one and three months after myopic laser in situ keratomileuses (LASIK) and photorefractive keratectomy (PRK) using double-pass aberrometry (HD Analyzer, Visiometrics S.L, Terrassa, Spain). The parameters analyzed included vision break-up time (VBUT), objective scattering index (OSI), modulation transfer function (MTF), and Strehl ratio (SR). The study included 141 eyes of 141 patients, of whom 89 underwent PRK and 52 underwent LASIK. No statistically significant differences were noted between the two techniques in any analyzed parameters at three months postoperatively. However, a significant drop was observed in all parameters one month after PRK. Only the OSI and VBUT remained significantly altered from baseline at the three months follow-up visit, with an increased OSI by 0.14 +/- 0.36 (p < 0.01) and a shortened VBUT by 0.57 +/- 2.3 s (p < 0.01). No correlation was found between the changes in optical and visual quality parameters and age, ablation depth, or postoperative spherical equivalent. The stability and quality of the retinal images were similar between LASIK and PRK at three months postoperatively. However, significant degradation in all parameters was found one month after PRK.
