Moisture chamber goggles for the treatment of postoperative dry eye in patients receiving SMILE and FS-LASIK surgery.

BACKGROUND: The incidence of refractive surgery-related dry eye disease (DED) is rising due to the increasing popularity of corneal refractive surgery. The moisture chamber goggles (MCGs) have been shown to tear evaporation by increasing local humidity and minimizing airflow. The current study aims to evaluate the efficacy of moisture chamber goggles for refractive surgery-related DED. METHODS: In this nonrandomized open-label controlled study, 78 participants (156 eyes) receiving refractive surgery were enrolled between July 2021 and April 2022, and sequentially allocated to MGC and control groups. 39 participants were allocated to the MGC groups, of which 53.8% received small-incision lenticule extraction (SMILE) and 46.2% received femtosecond laser-assisted in situ keratomileusis (FS-LASIK), and were instructed to wear MCGs for the duration of 1 month postoperatively, in addition to the standard postoperative treatment received by the control groups (56.4% SMILE, 43.6% FS-LASIK). Participants underwent full ophthalmic examinations, including visual acuity, manifest refraction, DED evaluations, and higher-order aberrations (HOAs), both preoperatively and at routine follow-ups 1 day, 1 week, and 1 month after surgery. DED parameters included non-invasive tear film break-up time (NIBUT), tear meniscus height (TMH), conjunctival congestion, lipid layer thickness (LLT), and ocular surface disease index (OSDI) questionnaires. Student's t-test was used for comparisons between control and MCG groups, and between preoperative and postoperative parameters within groups. RESULTS: Postoperative NIBUT decreased in both SMILE and FS-LASIK control groups 1 day after the surgery (SMILE, P = 0.001; FS-LASIK, P = 0.008), but not in the corresponding MCG groups (SMILE, P = 0.097; FS-LASIK, P = 0.331). TMH in the MCG group was significantly higher at 1 week (P = 0.039) and 1 month (P = 0.015) in SMILE, and 1 day (P = 0.003) in FS-LASIK groups. In FS-LASIK participants, significantly lower HOAs and coma levels in the MCG group were observed 1 day (total HOAs, P = 0.023; coma, P = 0.004) and 1 week (total HOAs, P = 0.010, coma, P = 0.004) after surgery. No consistent statistically significant intergroup difference was observed between MCG and control groups in conjunctival congestion, LLT, and OSDI. CONCLUSIONS: MCGs effectively slowed tear evaporation, increased tear film stability, and improved HOAs in patients receiving SMILE and FS-LASIK surgeries. MCG is an effective adjuvant therapy in the comprehensive management of refractive surgery-related DED.

Eye-mounting goggles to bridge the gap between benchtop experiments and in vivo robotic eye surgery.

A variety of robot-assisted surgical systems have been proposed to improve the precision of eye surgery. Evaluation of these systems has typically relied on benchtop experiments with artificial or enucleated eyes. However, this does not properly account for the types of head motion that are common among patients undergoing eye surgery, which a clinical robotic system will encounter. In vivo experiments are clinically realistic, but they are risky and thus require the robotic system to be at a sufficiently mature state of development. In this paper, we describe a low-cost device that enables an artificial or enucleated eye to be mounted to standard swim goggles worn by a human volunteer to enable more realistic evaluation of eye-surgery robots after benchtop studies and prior to in vivo studies. The mounted eye can rotate about its center, with a rotational stiffness matching that of an anesthetized patient's eye. We describe surgeon feedback and technical analyses to verify that various aspects of the design are sufficient for simulating a patient's eye during surgery.

Assessment of the Blue Light Ocular Hazard by Solar Measurements and the Impact of Selected Sunglasses Based upon the Limits of the International Commission on Non-Ionizing Radiation Protection Guideline.

ABSTRACT: A quantitative assessment of the blue light hazard for the human eye related to direct solar irradiation is presented. For six radiation situations, missing eye protection was compared to protection by nine different commercial sunglasses with and without an optimized blue light filter. Measurements of the solar irradiance were performed on Earth's surface as well as at an elevation of 12 km in the cockpit of an airliner. An irradiation time limit was calculated from the measurement data, within which the maximum blue light dose of 100 J m -2 , recommended by the International Commission on Non-Ionizing Radiation Protection and mandatory for the safe operation of lamps according to the norm ICE 62471, is reached. The results suggest that the blue light dose limit is violated within less than 3 s when looking without eye protection directly into the sun. For Category 3 sunglasses without the optimized blue light filter, time limits of 10 to 25 s on Earth's surface and 7 to 8 s at 12 km altitude were observed. The investigated Category 3 sunglasses with optimized blue light protection and suited for traffic use allow a time limit of more than 40 s on Earth's surface and 18 to 95 s in the airliner's cockpit. The outcome of the study is that the eye protection against blue light hazard related to solar radiation can be quantified using existing limits and that the choice of sunglasses is relevant: Traffic-worthy sunglasses optimized for protection against blue light hazard offer a better protection than non-optimized sunglasses.

Evaluation of operator eye exposure and eye protective devices in interventional radiology: Results on clinical staff and phantom.

PURPOSE: To assess occupational eye lens dose based on clinical monitoring of interventional radiologists and to assess personal protective eyewear (PPE) efficacy through measurements with anthropomorphic phantom. METHODS: Two positions of the operator with respect to X-ray beam were simulated with phantom. Dose reduction factor (DRF) of four PPE was assessed, as well as correlation between eye lens and whole-body doses. Brain dose was also assessed. Five radiologists were monitored for one-year clinical procedures. All subjects were equipped with whole-body dosimeter placed over lead apron at the chest level and eye lens dosimeter placed over the left side of the PPE. Kerma-Area Product (KAP) of procedures performed during the monitoring period was recorded. The correlation of eye lens dose with whole-body dose and KAP was assessed. RESULTS: DRF was 4.3/2.4 for wraparound glasses, 4.8/1.9 for fitover glasses, 9.1/6.8 for full-face visor in radial/femoral geometries. DRF of half-face visor depended on how it is worn (range 1.0-4.9). Statistically significant correlation between dose value over the PPE and chest dose was observed, while there was no correlation between eye lens dose and chest dose. The results on clinical staff showed statistically significant correlation between dose values over the PPE and KAP. CONCLUSIONS: All PPE showed significant DRF in all configurations, provided they were worn correctly. Single DRF value is not applicable to all clinical situations. KAP is a valuable tool for determining appropriate radiation protection measures.

RELATIONSHIPS BETWEEN TYPES OF PROTECTIVE EYEWEAR AND EYE LENS DOSE WITHIN ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY.

In this study, variations in eye lens dose across different types of protective operator eyewear as well as the most appropriate protective methods when conducting endoscopic retrograde cholangiopancreatography were evaluated. The eye lens doses of 10 types of commercially available protective eyewear were compared. The ratio of the measured value near the eye to the measured value at the eye lens position ranged from 0.65 to 5.40 and it varied according to the mounting position of the dosemeter as well as the type of protective eyewear. Thus, the eye lens dose may have been overestimated or underestimated. Regardless of the working conditions, a face shield type of protective eyewear is recommended to reduce the eye lens dose. Moreover, it is preferable to attach a lens dosemeter near the eye to measure and evaluate the eye lens dose.

Radiation Exposure of Crystalline Bodies during Interventional Therapy and Related Research Status.

The aim of this study was to estimate the exposure dose level of ocular corpuscles during the common interventional procedures of interventional radiology workers. This article retrospectively analyzed the general instruments and equipment of interventional therapy, the general methods and steps of interventional therapy, and the influence of X-ray of interventional surgery. The related contents of eye protection for interventional radiology workers were summarized. This study found that there was a significant linear correlation between the equivalent dose of lens and the exposure time. The tube voltage, tube current, and the size of fluoroscopic field of vision also have an impact on the radiation of workers during surgical exposure. Interventional surgery is difficult and easy. The exposure time of difficult surgery is relatively long, so the dose received by interventional staff is large. The intervention staff should improve their professional knowledge, be proficient in the operation technology, and try to reduce the exposure without affecting the diagnosis and treatment effect. During the intervention operation, the eye substance of the operator is exposed to a certain dose of radiation, and the wearing rate of protective lead glasses of the intervention staff is very low. Therefore, we must pay attention to the protection of the eyes, strengthen the protection management, and reduce the exposure dose of the intervention staff as much as possible.

An investigation into potential improvements in the design of lead glasses for protecting the eyes of interventional cardiologists.

The lens of the eye can be damaged by ionising radiation, so individuals whose eyes are exposed to radiation during their work may need to protect their eyes from exposure. Lead glasses are widely available, but there are questions about their efficiency in providing eye protection. In this study, Monte Carlo simulations are used to assess the efficiency of lead glasses in protecting the sensitive volume of the eye lens. Two designs currently available for interventional cardiologists are a wraparound (WA) style and ones with flat frontal lenses with side shielding. These designs were considered together with four modifications that would impact upon their efficiency: changing the lead equivalent thickness, adding lead to the frames, elongating the frontal lenses, and adding a closing shield to the bottom rim. For the eye closest to the source, standard models of lead glasses only decrease the radiation reaching the most sensitive region of the eye lens by 22% or less. Varying the lead thickness between 0.4 mm and 0.75 mm had little influence on the protection provided in the simulation of clinical use, neither did adding lead to the frames. Improved shielding was obtained by elongating the frontal lens, which could reduce radiation reaching the eye lens by up to 76%. Glasses with lenses that had a rim at the base, extending towards the face of the user, also provided better shielding than current models, decreasing the dose by up to 80%. In conclusion, elongating the frontal lens of lead glasses, especially of the WA design, could provide a three-fold increase in shielding efficiency and this is still valid for lenses with 0.4 mm lead equivalence.

Multipressure Dial Goggle Effects on Circumpapillary Structure and Microvasculature in Glaucoma Patients.

PURPOSE: To evaluate the effects of pressure changes induced by a multipressure dial (MPD) on circumpapillary retinal nerve fiber layer (RNFL) and capillary density (CD) measurements in patients with glaucoma using OCT angiography (OCTA). DESIGN: Prospective interventional study. PARTICIPANTS: Twenty-four patients with primary open-angle glaucoma. METHODS: One eye of each patient underwent negative pressure application with the MPD. The MPD alters intraocular pressure (IOP) relative to atmospheric pressure by generating a negative pressure vacuum within a goggle chamber that is placed over the eye. Each participant underwent serial high density OCTA imaging (AngioVue) of the optic nerve head at different negative pressure increments of -5 mmHg, starting from 0 mmHg, ending at -20 mmHg, and then returning to baseline. Images were acquired after 2 minutes of sustained negative pressure at each target pressure to allow for stabilization of the retinal structures and microvasculature. The RNFL thickness and CD measurements were automatically calculated using the native AngioVue software, and then exported for analysis. MAIN OUTCOME MEASURES: The influence of different levels of negative pressure on circumpapillary RNFL thickness and CD measurements, assessed by a linear mixed-effects model with repeated measures. RESULTS: The mean (± SD) age was 71.0 years (± 7.8 years), the baseline IOP was 17.5 mmHg (± 3.6 mmHg), and there was a mean 24-2 mean deviation of -2.80 dB (± 2.55 dB). Serial circumpapillary CD measurements showed a statistically significant dose-dependent increase from baseline, without negative pressure application, to the maximum negative pressure application of -20 mmHg (difference, 2.27%; P = 0.010). Capillary density measurements then decreased symmetrically when lowering the negative pressure to baseline. Circumpapillary CD measurements at target negative pressures of -10 mmHg, -15 mmHg, and -20 mmHg were significantly higher than the baseline measurements (all P values < 0.05). Circumpapillary RNFL thickness remained the same throughout different levels of negative pressure. CONCLUSIONS: Circumpapillary CD measurements showed a dose-dependent increase with the induction of negative pressure, while RNFL thickness measurements remained unchanged.

Introduction. In December 2019, in Wuhan, China, there was an outbreak of atypical pneumonia caused by the SARS-CoV-2 virus, which is a type of coronavirus causative of COVID-19, which overtime became a pandemic. In this context, the use of personal protective equipment is of special interest, especially when providing care in vaginal delivery, due to the confusion in obstetric circles regarding the best way to protect healthcare personnel in these cases. The objective of this review article is to identify which are the personal protective elements indicated for providing care in vaginal birth and their correct use during COVID-19. Division of Covered Topics. A narrative review of the literature was carried out, accessing the following databases: PubMed, Medline, Elsevier, Google Scholar, and websites such as the World Health Organization (WHO), Center for the Control and Prevention of Diseases (CDC), and the American College of Obstetricians and Gynecologists, among others.

[Estimation of Eye Lens Dose during the Handling of Radiopharmaceuticals and Using X-ray Protective Goggles for Dose Reduction in Nuclear Medicine].

PURPOSE: The purposes of this study were to estimate the eye lens dose during the handling of radiopharmaceuticals and to validate the requirement of X-ray protective goggles in nuclear medicine. METHOD: Simulated eye lens radiation exposure (3-mm dose equivalent rate) was measured using a radiophotoluminescent glass dosimeter (RPLD) positioned at distances of 30 and 60 cm from 99mTc, 111In, and 123I radiation sources. Reduction rates were evaluated for the following means of radiation protection: X-ray protective goggles (0.07-, 0.50-, and 0.75-mm lead equivalent), a syringe shield, and a lead glass plate. RESULT: 3-mm dose equivalent rates without protection were obtained at 6.13±0.13 µSv/min/GBq for 99mTc, 23.08±0.19 µSv/min/GBq for 111In, and 11.07±0.11 µSv/min/GBq for 123I. Reduction rates for each source were over 90% for the syringe shield and the lead glass plate. The 0.75-mm lead equivalent X-ray protective goggles decreased the 3-mm dose equivalent rate by 68.8% for 99mTc, 60.6% for 111In, and 68.1% for 123I. CONCLUSION: Although the estimated eye lens equivalent dose during the handling of radiopharmaceuticals did not exceed the threshold dose, our results suggest that 0.75-mm lead equivalent X-ray protective goggles are needed to reduce the exposure of the lens while handling 99mTc, 111In, and 123I radiation sources.

Influence of safety glasses, body height and magnification on the occupational eye lens dose during pelvic vascular interventions: a phantom study.

OBJECTIVE: By simulating a fluoroscopic-guided vascular intervention, two differently designed radiation safety glasses were compared. The impacts of changing viewing directions and body heights on the eye lens dose were evaluated. Additionally, the effect of variable magnification levels on the arising scattered radiation was determined. METHODS: A phantom head, replacing the operator's head, was positioned at different heights and rotated in steps of 20° in the horizontal plane. Thermoluminescent dosimeters (TLD), placed in the left orbit of the phantom, detected eye lens doses under protected and completely exposed conditions. In a second step, radiation dose values with increasing magnification levels were detected by RaySafe i3 dosimeters. RESULTS: Changing eye levels and head rotations resulted in a wide range of dose reduction factors (DRF) from 1.1 to 8.5. Increasing the vertical distance between the scattering body and the protective eyewear, DRFs markedly decreased for both glasses. Significant differences between protection glasses were observed. Increasing magnification with consecutively decreasing FOV size variably reduced the dose exposure to the eye lens between 47 and 83%, respectively. CONCLUSION: The safety glasses in the study effectively reduced the dose exposure to the eye lens. However, the extent of the protective effect was significant depending on eye levels and head rotations. This may lead to a false sense of safety for the medical staff. In addition, the application of magnification reduced the quantity of scattering dose significantly. To ensure safe working in the Cath-lab, additional use of protective equipment and the differences in design of protective eyewear should be considered. KEY POINTS: • Eye lens dose changes with physical size of the interventionist and viewing direction. • The use of magnification during fluoroscopic-guided interventions reduces scattered radiation.

The effects of eye masks on post-operative sleep quality and pain in school-age children with CHD.

OBJECTIVE: This study aimed to explore the effects of eye masks on the sleep quality and pain of school-age children with CHD after surgery. METHODS: Forty school-age children with CHD who underwent open-heart surgery in the Cardiac Surgery Department of a provincial hospital in China from January 2020 to December 2020 were selected. The children were randomly divided into the experimental group (n = 20) and the control group (n = 20). Children in the control group were given routine sleep care, and the children in the experimental group were given a sleep intervention with eye masks for three nights following the removal of tracheal intubation. The Pittsburgh Sleep Quality Index was used to evaluate the sleep quality of the children. The Children's Pain Behaviour Scale was used to evaluate the pain of the children. RESULTS: After three nights of receiving the eye masks intervention, the sleep quality scores of the children in the experimental group were significantly lower than those of the control group, the difference was statistically significant (p < 0.05) and the sleep quality of the children in the experimental group was higher. The pain scores of the children in the experimental group were significantly lower than those of the children in the control group, the difference was statistically significant (p < 0.05), and the children in the experimental group suffered less post-operative pain. CONCLUSION: Eye masks are a simple, safe and economical intervention, that is beneficial for improving the post-operative sleep quality and relieving post-operative pain in school-age children with congenital heart disease.

Eye protection in interventional procedures.

Data suggest that radiation-induced cataracts may form without a threshold and at low-radiation doses. Staff involved in interventional radiology and cardiology fluoroscopy-guided procedures have the potential to be exposed to radiation levels that may lead to eye lens injury and the occurrence of opacifications have been reported. Estimates of lens dose for various fluoroscopy procedures and predicted annual dosages have been provided in numerous publications. Available tools for eye lens radiation protection include accessory shields, drapes and glasses. While some tools are valuable, others provide limited protection to the eye. Reducing patient radiation dose will also reduce occupational exposure. Significant variability in reported dose measurements indicate dose levels are highly dependent on individual actions and exposure reduction is possible. Further follow-up studies of staff lens opacification are recommended along with eye lens dose measurements under current clinical practice conditions.

Combat-related ocular injuries in the Israel Defense Forces during the years 2013 to 2019.

BACKGROUND: Ocular injuries account for up to 13% of battle injuries, despite the implementation of advanced protective eyewear (PE). The aim of this study was to describe the extent of ocular injuries over the last years among Israel Defense Forces soldiers and to examine the change in PE policy introduced in 2013 and the effect of a high-intensity conflict on ocular injury characteristics. METHODS: This retrospective registry-based analysis derived data from the Israel Defense Forces Trauma Registry and included soldiers who sustained combat-related ocular injuries between the years 2013 and 2019. Demographic data and injury characteristics of casualties, as well as information regarding the use of PE, were collected and analyzed. RESULTS: A total of 2,312 military casualties were available for this study; the incidence of combat-related ocular injuries was 8.9% (n = 113). Ocular injuries occurred among male soldiers (98.2%) with a mean ± SD age of 22.7 ± 4.6 years; mechanism of injury was penetrating in 59.3% of the casualties and blunt in 22.1% of the casualties, ocular injury was isolated in 51.3% of the casualties, and others sustained concomitant injuries including head (32.7%), upper extremity injury (17.7%), lower extremity (15.9%), torso (8.0%), neck (6.2%), and other (5.9%) injuries. Ocular injuries rate was similar among casualties who used PE (11.2%) and those who did not use PE (13.0%) while injured (p = 0.596). Rate of open globe injuries was 9.1% in casualties who used PE and 39.5% (p = 0.002) in casualties who did not. CONCLUSION: Eye protection may significantly reduce ocular injuries severity. Education of the combatants on the use of PE and guidance of medical teams on proper assessment, initial treatment, and rapid evacuation of casualties are needed to improve visual outcomes of the casualties further. LEVEL OF EVIDENCE: Epidemiological study, level IV.

Partial recovery of visual function in a blind patient after optogenetic therapy.

Optogenetics may enable mutation-independent, circuit-specific restoration of neuronal function in neurological diseases. Retinitis pigmentosa is a neurodegenerative eye disease where loss of photoreceptors can lead to complete blindness. In a blind patient, we combined intraocular injection of an adeno-associated viral vector encoding ChrimsonR with light stimulation via engineered goggles. The goggles detect local changes in light intensity and project corresponding light pulses onto the retina in real time to activate optogenetically transduced retinal ganglion cells. The patient perceived, located, counted and touched different objects using the vector-treated eye alone while wearing the goggles. During visual perception, multichannel electroencephalographic recordings revealed object-related activity above the visual cortex. The patient could not visually detect any objects before injection with or without the goggles or after injection without the goggles. This is the first reported case of partial functional recovery in a neurodegenerative disease after optogenetic therapy.

Effect of the use of earplugs and eye masks on the quality of sleep after major abdominal surgery: a randomised controlled trial.

Significant sleep disturbance can occur following major abdominal surgery. We aimed to evaluate the effectiveness of earplugs and eye masks in improving sleep quality and patient satisfaction, reducing nursing demands and in the incidence of delirium in patients after major abdominal surgery. We conducted a randomised controlled trial in 100 patients undergoing major abdominal surgery. We randomly allocated participants to sleep with or without earplugs and eye masks on postoperative days 1-3. The primary outcome measure was sleep quality as measured by the Richards-Campbell Sleep Questionnaire. Secondary outcomes were patient satisfaction, frequency of nursing demand and incidence of delirium measured by the Neelon and Champagne Confusion Scale. Median (IQR [range]) sleep scores were 64 (38-74 [0-100] and 60 (44-82 [18-100]) for the control and intervention groups, respectively (p = 0.310). Age and Pittsburgh Sleep Quality Index scores were found to be significant factors affecting sleep quality. There were no differences in patient satisfaction, reduction in frequency of nursing demands or incidence of delirium on postoperative days 1-3 after major abdominal surgery. The compliance rate in the intervention group was 60-65%. This study has demonstrated that the use of earplugs and eye masks did not contribute to improvements in sleep quality. Of note, sleep quality was moderate, with higher age and worse baseline sleep quality contributing to worse sleep scores. More studies are needed to investigate interventions to improve sleep quality after major abdominal surgery.

Are X-ray Safety Glasses Alone Enough for Adequate Ocular Protection in Complex Radiological Interventions?

ABSTRACT: The maximum annual radiation ocular dose limit for medical staff has been reduced to 20 mSv in the current European directive 2013/59/Euratom. This multi-centric study aims at reporting the protected and unprotected eye lens doses in different fluoroscopically guided interventions and to evaluate any other factors that could influence the ocular dose. From July 2018 to July 2019, ocular radiation doses of six interventionists of four departments during complex interventions were recorded with a thermoluminescent dosimeter in front of and behind radiation protection glasses to measure the protected and unprotected doses. The position of personnel, intervention type, fluoroscopy time, total body dose and use of pre-installed protection devices like lead acrylic shields were also systematically recorded. Linear regression analysis was used to estimate the doses at 2 y and 5 y. The annual unprotected/protected ocular doses of six interventionists were 67/21, 32.7/3.3, 27.4/5.1, 7/0, 21.8/2.2, and 0/0 mSv, respectively. The unprotected dose crossed the 20-mSv annual limits for four interventionists and protected dose for one less experienced interventionist. The estimated 5-y protected ocular dose of this interventionist was 101.318 mSv (95%CI 96.066-106.57), also crossing the 5-y limit. The use of a lead acrylic shield was observed to have a significant effect in reducing ocular doses. The annual unprotected and protected ocular doses for interventionists dealing with complex interventions could cross the present permitted yearly limit. The measurement of significant protected ocular dose behind the radiation protection glasses emphasizes the additional indispensable role of pre-installed radiation protection devices and training in reducing radiation doses for complex procedures.
