Tear Film Hyperosmolarity is Associated with Increased Variation of Light Scatter Following Cataract Surgery.

Purpose: To study the association between tear film hyperosmolarity and ocular light scatter in a cataract surgery population. Patients and Methods: Contiguous, 20-second objective scatter index (OSI) scans were recorded in hyperosmolar (≥320 mOsm/L) and normal subjects (<308 mOsm/L) with cataract nuclear opacity ≥3. OSI was measured at screening, baseline and 90 days following surgery. Along with symptoms of ocular surface disease, slit-lamp examination included corneal staining (0-3), tear film breakup time (TBUT) and evaluation of meibomian gland disease (MGD). An additional cohort of hyperosmolar subjects were measured for OSI at screening, baseline, and 5, 10, 15 and 30 minutes following instillation of 0.18% sodium hyaluronate (HA). Results: Thirty-one eyes of 31 patients were included. There was a significant difference in post-operative OSI variation when comparing hyperosmolar (0.65±0.30, N=11) to normal subjects (0.33±0.11, N=10, p=0.005). Of note, there were no significant differences in OSI variation when subjects were sorted by staining (p=0.9), TBUT (p=0.7), symptoms (p=0.7), or MGD status (p=0.9). Instillation of 0.18% HA (N=10) did not alter OSI at 5 minutes, but significant reductions in OSI of 28.8%, 38.5% and 36.7% (all p < 0.001) were observed at 10, 15 and 30 minutes. Conclusion: Hyperosmolar patients exhibited significantly increased variation in light scatter following cataract surgery that was undifferentiated by staining or TBUT. Elevated osmolarity may be indicative of light scatter equivalent to that of a grade 2-3 cataract.

Novel heterozygous OPA3 variant in a family with congenital cataracts, sensorineural hearing loss and neuropathy, without optic atrophy and comparison of pathogenic and population variants.

Heterozygous mutations in the OPA3 gene are associated with autosomal dominant optic atrophy-3 (OPA3), whereas biallelic mutations cause autosomal recessive 3-methylglutaconic aciduria type III. To date, all cases with pathogenic variants in the gene OPA3 have presented with optic atrophy. We report a large family with congenital cataracts, hearing loss and neuropathy, with a likely pathogenic novel missense variant in OPA3, c.30G>C; p.(Lys10Asn) that segregates with disease in the family pedigree. The family's clinical presentation has significant phenotypic overlap with previously reported cases of OPA3, except for a notable lack of optic atrophy. The analysis of all known disease-associated variants in OPA3 revealed an enrichment in missense variants in patients with OPA3 phenotype compared with loss-of-function variants, which are more likely to be observed in individuals with 3-methylglutaconic aciduria type III, supporting different mechanisms of disease. This case broadens the clinical and genetic spectrum associated with OPA3 mutations and highlights that optic atrophy is not an obligate feature of OPA3-related disorders.

Retisert implantation without incisional sclerotomy in patients with uveitis and extensive pars plana fibrosis.

Purpose: To describe an alternate surgical technique for fluocinolone acetonide (Retisert) implantation in patients with extensive pars plana and pars plicata fibrosis secondary to chronic non-infectious uveitis. Methods: This retrospective, interventional case series included five eyes of four patients who had poorly controlled chronic non-infectious uveitis. Retisert was implanted successfully using a novel approach. The device was introduced into the posterior segment through the anterior chamber and posterior capsulotomy, forgoing the need for full-thickness scleral incision and minimizing the risk of retinal detachment and associated complications. Results: Five eyes underwent passage of Retisert implant through the anterior segment via a limbal incision and a posterior capsulotomy. Retisert was successfully implanted in all patients in the posterior chamber. No intraoperative or postoperative complications were encountered. Up until the last follow-up, all eyes demonstrated the stability of the implant. Visual acuity improved in four out of five eyes. Conclusions: Retisert can be implanted via the anterior chamber in patients with extensive fibrosis in the pars plana and pars plicata regions. This approach may minimize the risk of retinal traction and damage to the implant when compared to the traditional full-thickness sclerotomy method in these high-risk cases.

Immediate Sequential Bilateral Cataract Surgery in Patients with Bilateral Visually Significant Cataracts.

Purpose: To report our experience of performing immediate sequential bilateral cataract surgery (ISBCS) in patients with visually significant cataracts and reduced preoperative corrected distance visual acuity (CDVA). Methods: Data of patients who underwent ISBCS for visually significant cataracts and had preoperative CDVA ≤20/32 (≤0.2 logMAR) in each eye were retrospectively reviewed. Refractive and visual outcomes were evaluated for the last available postoperative visit. Intraoperative and serious postoperative adverse events occurring within the first three months of surgery were reviewed. Results: A total of 1335 patients (2670 eyes) were included in the analysis, with a mean age of 71.9 ± 9.5 years. On the last visit, 50.2% and 89.1% of eyes achieved uncorrected distance visual acuity (UDVA) ≥20/20 (0.0 logMAR) and ≥20/32 (0.2 logMAR), respectively. Of all eyes, 83.8% were within ±0.50D, and 96.4% were within ±1.00 D of emmetropia. Ten patients had postoperative bilateral ametropia of more than 1.00D in each eye, but eight of them still achieved binocular UDVA ≥20/40. Intraoperative events occurred in 14 eyes of 13 patients (per-eye incidence: 0.524% or 1 in 191 eyes). A total of 86 postoperative adverse events occurred in 80 eyes of 53 patients (per-eye incidence 2.996% or 1 in 33 eyes), of which cystoid macular edema was the most common. Only three eyes had CDVA reduced by more than two Snellen lines compared to preoperative CDVA, two of which were not related to cataract surgery. There was no patient with bilateral CDVA loss. Conclusion: In our cohort of patients with visually significant cataracts, ISBCS resulted in good refractive predictability and a low incidence of serious adverse events.

Comparative Analysis of Clinical and Patient-Reported Outcomes of a New Enhanced Monofocal IOL and a Conventional Monofocal IOL.

Purpose: To compare the outcomes of the Tecnis Eyhance ICB00 IOL, designed to enhance intermediate vision, to a conventional Tecnis Monofocal ZCB00 IOL. Methods: This retrospective analysis compared two cohorts of patients undergoing lens replacement surgery with bilateral implantation of the Tecnis ICB00 or the Tecnis ZCB00 IOL (383 patients in each group). Monocular and binocular uncorrected distance (UDVA), intermediate (UIVA; 66cm), and near (UNVA; 40cm) visual acuities, refractive predictability, and patient-reported outcomes were compared. A sub-analysis of patients with the Eyhance IOL was performed to compare patients who achieved bilateral emmetropia to those with mini-monovision. One-month postoperative outcomes were analyzed. Results: Both groups had comparable UDVA outcomes. On average, both monocular and binocular UIVAs were approximately one Snellen line better in patients implanted with Eyhance IOL (monocular UIVA: ICB00 0.23 ± 0.18 logMAR, ZCB00 0.33 ± 0.19 logMAR; binocular UIVA: ICB00 0.18 ± 0.18 logMAR, ZCB00 0.26 ± 0.20 logMAR, p < 0.01). Likewise, the mean UNVA was also one Snellen line better with the ICB00 model (monocular UNVA: ICB00 0.51 ± 0.20 logMAR, ZCB00 0.61 ± 0.18 logMAR; binocular UNVA: ICB00 0.42 ± 0.19 logMAR, ZCB00 0.51 ± 0.22 logMAR, p < 0.01). There was no difference between the two groups in overall satisfaction or visual phenomena. A subgroup of patients who achieved mini-monovision with Eyhance IOL had, on average, one Snellen line better UIVA and UNVA compared to patients with bilateral emmetropia. Conclusion: Patients receiving the enhanced monofocal IOL had better intermediate and near vision compared to those receiving the conventional monofocal IOL, with similar levels of patient-reported photic phenomena in both groups.

Current state and future perspectives in the diagnosis of eyelid margin disease: clinical review.

The eyelid margin is vital to ocular surface integrity. Much peer-reviewed literature has been established in eyelid margin inflammation, better known as blepharitis. The purpose was to review and understand the impact of eyelid margin disease. Anterior blepharitis causes inflammation at the eyelash base, ciliary follicles, and the palpebral skin. Posterior blepharitis occurs when there is inflammation with the posterior eyelid margin disease. In common usage, the term "blepharitis" used alone almost always refers to anterior blepharitis. Classification of eyelid margin disease should be based on etiopathogenesis, location, primary vs secondary, and chronicity. Blepharitis has several etiopathologies (infectious, inflammatory, and squamous). Meibomian gland dysfunction (MGD) can refer to the functional and/or structural problems with the meibomian gland. Meibomitis (or meibomianitis) occurs when there is inflammation associated with the MGD. The presence of blepharitis and/or MGD (with or without inflammation) can affect the ocular surface and thereby affect anterior segment and cataract surgeries. This review article evaluates the differential diagnoses of eyelid margin disease, including various forms of blepharitis, MGD, and meibomitis.

A survey of perceptions of exposure to new technology in residents and practicing ophthalmologists.

BACKGROUND: Incorporation of the rapid advances in ophthalmologic surgical and diagnostic techniques inherent in the field poses a challenge to residency training programs. This study investigates exposure to new technologies during residency and perception of its impact on practice patterns. METHODS: Ophthalmology residents at various training levels and practicing ophthalmologists who had completed their training were invited to participate in a survey study assessing exposure to various technologies in residency and in practice. Data collection occurred from December 2022 to June 2023. Descriptive statistics were performed. RESULTS: The study received 132 unique responses, including 63 ophthalmology residents and 69 practicing ophthalmologists. 65.2% (n = 45) of practicing ophthalmologists and 47.6% (n = 30) of current residents reported discussion/training on newly developed products on the market (e.g. premium IOLS, MIGS), was "minimally discussed but not emphasized" or "not discussed at all" in residency. 55.1% (n = 38) of practicing ophthalmologists reported that exposure to new technologies during residency did influence types of technologies employed during practice. The majority resident physicians reported enjoying being trained on newer technology and feeling more prepared for future changes in the field (95.2%, n = 60) and felt that having industry partnerships in residency enhances education and training (90.5%, n = 57). CONCLUSIONS: Considering how to maximize exposure to newer technologies/devices during residency training is important, and may contribute to training more confident, adaptable surgeons, who are more likely to critically consider new technologies and adopt promising ones into their future clinical practice.

Angle Kappa is Not Correlated with Patient-Reported Outcomes After Multifocal Lens Implantation.

Purpose: To examine the effect of preoperative angle kappa on patient-reported outcomes after multifocal lens placement during cataract surgery and determine if it is an effective measure for preoperative patients screening for multifocal lens placement. Setting: Private refractive surgery clinics. Design: Retrospective cohort study. Methods: All patients undergoing bilateral cataract or refractive lens exchange surgery with a target of emmetropia between 2013 and 2017 at Optical Express (Glasgow, UK) with multifocal lens placement for whom preoperative angle kappa measurement and a postoperative month 1 patient-reported outcomes measures were available were included. Results: A total of 1368 patients were identified. Median preoperative angle kappa was 0.41mm with an interquartile range of 0.30mm to 0.53mm. Preoperative angle kappa did not have a significant association with patient-reported satisfaction with vision (correlation coefficient 0.15, 95% confidence interval -0.081 to 0.39, P = 0.20) nor with patient-reported photic phenomena (P > 0.09 for all comparisons). A receiver-operator characteristic analysis did not yield a viable cutoff predictive of patient-reported satisfaction. Conclusion: Angle kappa was not predictive of patient-reported satisfaction in this study. This study did not find evidence that it should be used as a screening test for patients considering multifocal intraocular lens placement.

Eyelid margin disease (blepharitis and meibomian gland dysfunction): clinical review of evidence-based and emerging treatments.

Blepharitis is a common ophthalmic condition with multiple etiologies and no definitive, universal treatment. The treatment modalities for managing lid margin diseases vary depending on the disease's cause, location, and severity. For anterior blepharitis, management options include eyelid hygiene with warm compresses, eyelid scrubs, baby shampoo, and over-the-counter eyelid cleansers. Topical antibiotics and antibiotic-steroid combination drops/ointments for the eye and eyelid may accompany these. For posterior blepharitis/meibomian gland dysfunction (MGD), at-home warm compress or in-office administration of heat therapy/thermal pulsation treatment that aims to clear obstruction in the meibomian glands and restore meibum secretions to maintain a healthy tear film is recommended. In addition to the above treatment strategies, various other compounds to manage lid margin diseases are in the late stages of development. This review summarizes the available treatment modalities or those in the pipeline for treating blepharitis and MGD.

Bilaterally subluxed diffractive intraocular lenses: big expectations and even bigger comorbidities.

A 78-year-old woman with an ocular history of cataract surgery with a diffractive intraocular lens (IOL) in each eye has developed fluctuating vision, greater in the right eye than the left eye, after 4 years. She has a history of inactive central serous retinopathy and a vision potential of 20/25 + 2 in the right eye and 20/25 in the left eye. She has well-controlled diabetes, hypertension, and hypercholesterolemia. She has enjoyed her spectacle independence for some time and wishes to have her vision restored. On examination, her uncorrected distance visual acuity (UDVA) was 20/50 in the right eye and 20/25 in the left eye and her uncorrected near visual acuity (UNVA) was J3 in the right eye and J1 in the left eye. Intraocular pressures (IOPs) measured 22 mm Hg in the right eye and 18 mm Hg in the left eye. Pupils had limited reactivity with irregularity in the right eye but no obvious relative afferent pupillary defect. Motility and confrontation visual fields were unremarkable in both eyes. Retinal acuity meter was 20/20 in both eyes, and manifest refraction was plano -1.25 × 105 20/40, J3 in the right eye and +0.50 × 20/25, J1 in the left eye. Pertinent findings on slitlamp examination included temporal iris atrophy and transillumination defects greater in the right eye than the left eye, peripupillary pseudoexfoliative changes in both eyes, significant inferior subluxation of a diffractive 3-piece posterior chamber IOL in the capsular bag with lens-pitting peripherally and few central, moderate pseudophacodonesis, and an open posterior capsule in the right eye. In the left eye, she had mild inferior subluxation of a single-piece acrylic diffractive IOL in the capsular bag with moderate pseudophacodonesis and an open posterior capsule (Figure 1JOURNAL/jcrs/04.03/02158034-202403000-00019/figure1/v/2024-02-20T193212Z/r/image-tiff). All other anterior segment findings were unremarkable. On dilated posterior examination, she had a cup-to-disc ratio of 0.50 in the right eye and 0.65 in the left eye without edema hemorrhage or pallor. There were attenuated vessels in both eyes, posterior vitreous detachment in both eyes, and a few small drusen peripherally in both eyes. There was retinal pigment epithelium irregularity and dropout parafoveal in the right eye and subfoveal in the left eye (Figure 2). There was no evidence of macular edema, subretinal fluid, choroidal thickening, or neovascular membranes. The periphery was unremarkable in both eyes.JOURNAL/jcrs/04.03/02158034-202403000-00019/figure2/v/2024-02-20T193212Z/r/image-tiff What testing would you obtain preoperatively to help guide your decision-making? How would you counsel the patient regarding comorbid conditions and expectations?

Effect of residual sphere on uncorrected visual acuity and satisfaction in patients with monofocal and multifocal intraocular lenses.

PURPOSE: To assess the effect of residual sphere on vision and satisfaction in pseudophakic patients. SETTING: Private clinics, United Kingdom. DESIGN: Retrospective case series. METHODS: A multivariate model evaluated the effect of 1-month residual sphere on outcomes of pseudophakic patients. Odds ratios (ORs) were calculated to assess the relative risk of not achieving ≥20/20 monocular uncorrected distance visual acuity (UDVA), ≥20/50 uncorrected near visual acuity (UNVA), and not being satisfied with vision. ORs were assessed for residual sphere -1.00 to +1.00 diopter (D) in quarter-diopter steps, using 0.00 D as a reference. RESULTS: The analysis included 38 828 multifocal and 11 571 monofocal intraocular lenses (IOLs). The residual myopic sphere ≤-0.25 D and hyperopic sphere ≥+0.50 D had a clinically meaningful effect on UDVA. Although monofocal IOLs had an improvement in UNVA with every additional 0.25 D of myopia, the change in ORs with increasing myopia was not significant for multifocal IOLs. The mean improvement in UNVA comparing eyes with 0.00 D and -1.00 D sphere was 0.26 logMAR for monofocal and 0.03 logMAR for multifocal IOLs. Low near-addition IOLs had a slightly higher gain in UNVA with increasing myopia, but the gain was not as substantial as with monofocal IOLs. The effect of ametropia on satisfaction was more pronounced for multifocal IOLs. For every 0.25 D of residual myopia, there was >25% increase in dissatisfied patients. CONCLUSIONS: Although myopia improved UNVA in eyes with monofocal IOL, multifocal IOLs did not benefit from residual myopia. Multifocal IOL patients desiring distance vision should be targeted closest to emmetropia, even if it means targeting slight hyperopia.

Toric Monofocal Intraocular Lenses for the Correction of Astigmatism during Cataract Surgery: A Report by the American Academy of Ophthalmology.

PURPOSE: To review the published literature evaluating the visual and refractive outcomes and rotational stability of eyes implanted with toric monofocal intraocular lenses (IOLs) for the correction of keratometric astigmatism during cataract surgery and to compare those outcomes with outcomes of eyes implanted with nontoric monofocal IOLs and other astigmatism management methods performed during cataract surgery. This assessment was restricted to the toric IOLs available in the United States. METHODS: A literature search of English-language publications in the PubMed database was last conducted in July 2022. The search identified 906 potentially relevant citations, and after review of the abstracts, 63 were selected for full-text review. Twenty-one studies ultimately were determined to be relevant to the assessment criteria and were selected for inclusion. The panel methodologist assigned each a level of evidence rating; 12 studies were rated level I and 9 studies were rated level II. RESULTS: Eyes implanted with toric IOLs showed excellent postoperative uncorrected distance visual acuity (UCDVA), reduction of postoperative refractive astigmatism, and good rotational stability. Uncorrected distance visual acuity was better and postoperative cylinder was lower with toric IOLs, regardless of manufacturer, when compared with nontoric monofocal IOLs. Correcting pre-existing astigmatism with toric IOLs was more effective and predictable than using corneal relaxing incisions (CRIs), especially in the presence of higher magnitudes of astigmatism. CONCLUSIONS: Toric monofocal IOLs are effective in neutralizing pre-existing corneal astigmatism at the time of cataract surgery and result in better UCDVA and significant reductions in postoperative refractive astigmatism compared with nontoric monofocal IOLs. Toric IOLs result in better astigmatic correction than CRIs, particularly at high magnitudes of astigmatism.

Comparison of the 1st Generation and 3rd Generation Wavefront-Guided LASIK for the Treatment of Myopia and Myopic Astigmatism.

Purpose: To compare refractive, visual, and patient-reported outcomes associated with a 1st generation wavefront-guided (WFG) treatment with those associated with a 3rd generation WFG treatment. Patients and Methods: This retrospective study included patients who underwent femtosecond laser-assisted in situ keratomileusis (LASIK) for myopia/myopic astigmatism. Two random stratified samples of patients who underwent either 1stgeneration (WaveScan, Johnson & Johnson Vision, Santa Ana, CA) or 3rd generation (iDesign 2.0, Johnson & Johnson Vision, Santa Ana, CA) treatment matched on preoperative refraction were compared (4290 eyes of 2145 patients in each group). One-month postoperative visual, refractive, and patient-reported outcomes were analyzed. Refractive and monocular visual acuity analyses were performed using one random eye of each patient. Results: The percentage of eyes achieving 20/20 or better uncorrected vision was 91.3% (1958/2145) in the 1st generation group and 95.9% (2056/2145) in the 3rd generation group (p<0.01). Binocularly, the percentage of patients with 20/20 or better UDVA was 97.0% (2080/2145) and 99.2% (2127/2145) in the 1st and 3rd generation groups, respectively (p<0.01). The mean postoperative MSE was -0.01 ± 0.33 D in the 1st generation group and +0.19 ± 0.33 D in the 3rd generation group (p<0.01). Postoperative refractive astigmatism had a mean value of -0.20 ± 0.26 D and -0.18 ± 0.24 D in the 1st and 3rd generation groups, respectively (p<0.01). The mean correction index of refractive astigmatism was 1.09 ± 0.53 in the 1st generation group and 1.02 ± 0.38 in the 3rd generation group, p<0.01. The overall percentage of patients satisfied with vision was 92.8% (1991/2145 patients) in the 1st generation group and 97.3% (2087/2145 patients) in the 3rd generation group (p<0.01). Conclusion: For the majority of postoperative variables, there were significant differences between 1st and 3rd generation treatments. The 3rd generation treatments had better visual acuity outcomes and higher patient satisfaction.

Early Clinical Experience with a New Hydrophobic Acrylic Single-Piece Monofocal Intraocular Lens.

Purpose: To evaluate early clinical outcomes and adverse events (AEs) in cataract patients following implantation of a monofocal hydrophobic acrylic IOL with a new optimized non-constant aberration-correcting design (CT LUCIA 621P). Methods: This retrospective study included patients with visually significant cataracts who underwent implantation of the CT LUCIA 621P IOL. Refraction, corrected (CDVA) and uncorrected (UDVA) visual acuity of the last available visit were used in the analysis. Intraoperative and postoperative AEs of the cohort were reviewed. Results: A total of 191 eyes of 133 patients with the mean age of 70.2±11.2 years were included in this study. The mean follow-up time of the last available visit was 1.7±1.3 months. The mean postoperative monocular UDVA was 0.09±0.16 logMAR (≈20/25), and 74.9% (143/191) eyes achieved ≥20/25 UDVA. The percentage of eyes with manifest spherical equivalent (MSE) within ±0.50D and ±1.00D of emmetropia was 84.8% (162/191) and 98.4% (188/191), respectively. Linear regression of attempted vs achieved MSE showed a tight relationship, with the coefficient of determination close to 1 (R2=0.99), indicating a very predictable refractive correction. The reported AEs were those typically expected after cataract surgery. There were no AEs related to intraoperative manipulation with the IOL/injector or to postoperative stability of the IOL in the capsular bag. No eye lost ≥2 lines of CDVA. Conclusion: The implantation of CT LUCIA 621P resulted in good refractive predictability and visual outcomes. No IOL-related adverse events were reported.

Late approach for LASIK flap striae.

A 24-year-old man was referred for postrefractive surgery evaluation. The patient had a history of uneventful laser in situ keratomileusis (LASIK) in both eyes 3 months previously. According to the surgeon who originally performed the surgery, on slitlamp examination, only microstriae in the left eye was detected on postoperative day 1 and a more conservative follow-up approach was adopted without further immediate intervention. The patient returned only 3 months after surgery, complaining of low vision in the left eye that, according to the patient, had been present since postoperative week 2. The patient was then referred for examination and surgical procedure with a diagnosis of significant postoperative striae. The slitlamp examination revealed a LASIK flap with striae, epithelial filling, and a wrinkled appearance (Figure 1JOURNAL/jcrs/04.03/02158034-202312000-00017/figure1/v/2023-11-20T151558Z/r/image-tiff). There were no signs of infection or inflammation. Originally, the LASIK flap was programmed to be 110 µm. Preoperative manifest refraction in the right eye was -5.25 (20/20) and in the left eye was -5.25 (20/20). Assuming it is a case of late-approach LASIK flap striae, how would you proceed? Would you try to hydrate and lift the flap and just reposition it? Would you avoid lifting and associate phototherapeutic keratectomy (PTK) with excimer laser on top of the flap? Would you consider topo-guided surgery with regularization of the visual axis or even amputation of the flap?

Modified intrascleral haptic fixation of the light adjustable lens in a case of spontaneous adult-onset bilateral lens subluxation.

Purpose: To describe the application of the light adjustable lens (LAL) using an intrascleral haptic fixation (ISHF) technique for the correction of aphakia and post-operative refractive error. Observation: The LAL was placed using a modified trocar-based ISHF technique for visual rehabilitation following removal of bilateral cataracts in a patient with ectopia lentis. She ultimately obtained an excellent refractive outcome after adjustment with micro-monovision. Conclusions and Importance: Secondary intraocular lens placement has a much higher risk of residual ametropia than traditional in-the-bag lens placement. The ISHF technique with the LAL presents a solution for eliminating postoperative refractive error in patients requiring scleral-fixated lenses.

Isolated Ocular Mpox without Skin Lesions, United States.

We report a case of a 53-year-old HIV-negative patient in San Francisco, California, USA, with no classic mpox prodromal symptoms or skin lesions who experienced fulminant, vision-threatening scleritis, keratitis, and uveitis. Deep sequence analysis identified monkeypox virus RNA in the aqueous humor. We confirmed the virus on the cornea and sclera by PCR.

Immediate Sequential Bilateral Surgery in Refractive Lens Exchange Patients: Clinical Outcomes and Adverse Events.

PURPOSE: To evaluate outcomes and the incidence of adverse events (AEs) in patients who underwent bilateral same-day refractive lens exchange (RLE). DESIGN: Retrospective case series. PARTICIPANTS: Patients of a private intraocular surgery provider in the United Kingdom who underwent RLE in both eyes on the same day with treatment dates between March 2018 and December 2021. METHODS: Clinical outcomes and AEs were collected for a continuous cohort of patients undergoing bilateral same-day RLE (in the absence of visually significant cataracts) or had mild cataracts (corrected visual acuity ≥ 20/40). One-month clinical outcomes were analyzed. MAIN OUTCOME MEASURES: Refractive outcomes and visual acuity, intraoperative and postoperative AEs, and secondary surgical interventions recorded within the first month after surgery. RESULTS: A total of 17 330 patients (34 660 eyes) were included in the analysis. Of these, 28 827 eyes received a multifocal intraocular lens (IOL), and 5833 eyes had a monofocal IOL. The percentage of eyes within ±0.50 diopters (D) of intended refraction was 85.5% and 86.2% for monofocal and multifocal IOL eyes, respectively. There was a total of 55 intraoperative AEs recorded in 55 eyes of 54 patients (per-eye incidence: 0.159%). Posterior capsule tear was the most common intraoperative event occurring in 37 eyes (0.107%). The number of AEs recorded within the first postoperative month was 267, occurring in 263 eyes of 177 patients (per-eye incidence: 0.759%). These included cystoid macular edema (CME) (172 eyes; 0.496%), significant corneal edema (28 eyes; 0.081%), persistent inflammation (27 eyes; 0.078%), significantly raised intraocular pressure (27 eyes; 0.078%), toxic anterior segment syndrome (8 eyes; 0.023%), wound leak (3 eyes; 0.009%), retinal detachment (1 eye; 0.003%), and retinal tear (1 eye; 0.003%). There were 56 secondary surgical interventions recorded within the first month of surgery, occurring in 54 eyes of 47 patients (per-eye incidence: 0.156%). The most common secondary intervention was the rotation of a misaligned toric IOL (24 eyes; 0.069%). CONCLUSIONS: Elective same-day bilateral RLE had a low incidence of serious AEs, and high refractive predictability.

OC-01 (Varenicline Solution) Nasal Spray for the Treatment of Dry Eye Disease Signs and Symptoms in Subjects with Autoimmune Disease: Integrated Data from ONSET-1 and ONSET-2.

Purpose: We evaluate the treatment effect of OC-01 (varenicline solution) nasal spray (VNS) in dry eye disease (DED) subjects from two randomized trials who self-reported autoimmune disease (AID). Patients and Methods: Post hoc subgroup analysis of subjects reporting a history of AID from the integrated OC-01 VNS 0.03 or 0.06 mg and vehicle control (VC) treatment groups of the ONSET-1 and ONSET-2 trials. Mean change in Schirmer test with anesthesia score (STS, mm) and Eye Dryness Score (EDS) from baseline to 28 days was compared between OC-01 VNS and VC groups. Consistency of treatment effect in subjects with and without AID was evaluated using treatment-subgroup interaction terms in ANCOVA models for mean changes from baseline STS and EDS, and in a logistic regression model for proportion achieving ≥10 mm STS improvement. Results: Of the 891 participants, 31 reported comorbid AID. In all models, the treatment-subgroup interaction terms were not significant (p>0.05), indicating consistency of therapeutic effect of OC-01 VNS in subjects with and without AID. In subjects with AID, the treatment difference for STS was 11.8 mm and -9.3 for EDS and difference for proportion of subjects with ≥10 mm STS improvement was 61.1%. The most common adverse event was sneeze (82-84%), graded as mild by 98% of subjects. Conclusion: OC-01 VNS demonstrated consistency in improving both tear production and patient-reported symptoms in subjects with AID, consistent with pivotal ONSET-1 and 2 trial results. Further investigation is warranted, and results may further support use of OC-01 VNS for DED in AID patients.

Management of Pain after Photorefractive Keratectomy: A Report by the American Academy of Ophthalmology.

OBJECTIVE: To evaluate current best practices for postoperative photorefractive keratectomy (PRK) pain control. METHODS: Literature searches in the PubMed database were last conducted in October 2021 and were restricted to publications in English. This search identified 219 citations, of which 84 were reviewed in full text for their relevance to the scope of this assessment. Fifty-one articles met the criteria for inclusion; 16 studies were rated level I, 33 studies were rated level II, and 2 studies were rated level III. RESULTS: Systemic opioid and nonsteroidal anti-inflammatory drugs (NSAIDs); topical NSAIDs; postoperative cold patches; bandage soft contact lenses (BCLs), notably senofilcon A contact lenses; and topical anesthetics were demonstrated to offer significantly better pain control than comparison treatments. Some other commonly reported pain mitigation interventions such as systemic gabapentinoids, chilled intraoperative balanced salt solution (BSS) irrigation, cycloplegia, and specific surface ablation technique strategies offered limited improvement in pain control over control treatments. CONCLUSIONS: Systemic NSAIDs and opioid medications, topical NSAIDs, cold patches, BCLs, and topical anesthetics have been shown to provide improved pain control over alternative strategies and allow PRK-associated pain to be more tolerable for patients.
