Three impactful studies span prevention, aesthetics, and dermatologic therapy. A BMJ Open Ophthalmology study proposes a contact lens Sun Protection Factor (CL-SPF) with laboratory, ray-tracing, and cell assays, enabling clearer UV-protection communication. An international Delphi consensus outlines first global guidance for managing aesthetic needs in medication-driven weight loss. A randomized trial supports facial/neck atopic dermatitis control with ruxolitinib cream using decentralized, photo-based assessments.
Research Themes
- UV protection metrics and ocular health communication
- Aesthetic management during medication-driven weight loss (GLP-1 era)
- Topical JAK inhibition for facial/neck atopic dermatitis
Selected Articles
1. Development of a Sun Protection Factor for contact lenses (CL-SPF).
Using standardized SPF methods, spectrophotometry, ray tracing, and in vitro cell assays, the authors propose a contact lens SPF (CL-SPF) that maps lens UV-block performance to familiar SPF categories. Class 1 UV-blocking lenses reached CL-SPF ~60–66 (SPF 50+ equivalent), while non-blocking lenses offered CL-SPF ~1–2. Geometry-dependent sunglass gaps and higher conjunctival UV susceptibility underscore that lenses protect mainly the cornea.
Impact: Introduces a consumer-friendly, cross-disciplinary metric with methodological triangulation that can standardize UV-protection labeling for contact lenses and inform counseling alongside sunglasses use.
Clinical Implications: Eye care professionals can use CL-SPF to communicate UV protection, recommend Class 1 UV-blocking lenses for high-risk patients, and emphasize that contact lenses do not protect exposed conjunctiva/sclera—necessitating sunglasses and hats.
Key Findings
- Measured UV transmission of 15 contact lenses and 3 spectacle materials; derived CL-SPF using standard in vitro SPF methodology.
- Non-UV-blocking lenses: CL-SPF 1.0–2.0; Class 2 blockers: 12.3–24.8 (≈SPF15); Class 1 blockers: 59.6–66.2 (≈SPF50+).
- Ray tracing showed sunglasses’ ocular protection varies with solar angle and head orientation; average 76%–89% light reduction depending on tint.
- In vitro assays indicate ocular surface cell damage profile similar to skin, with conjunctival cells more UV-susceptible.
Methodological Strengths
- Triangulation of spectrophotometry, standardized SPF modeling, ray tracing, and cell assays.
- Direct mapping to widely understood SPF categories enhances translational relevance.
Limitations
- In vitro and modeling study without clinical UV exposure outcomes.
- Limited product set and lab conditions may not capture real-world wear environments.
Future Directions: Prospective studies linking CL-SPF categories to clinical photoprotection outcomes and development of standardized labeling across manufacturers; evaluation of combined strategies (CLs + sunglasses/hats).
2. Consensus Statements on Managing Aesthetic Needs in Prescription Medication-Driven Weight Loss Patients: An International, Multidisciplinary Delphi Study.
Through a three-round international Delphi process grounded in interviews, market research, and a literature review, experts defined medication-driven weight loss (mdWL), identified affected facial tissue layers (skin; superficial/deep fat), and recommended 3D volumetric analysis plus PROMs for assessment. The consensus outlines sequencing and timing of non-surgical treatments and highlights patient/physician concerns to guide aesthetic care in the GLP-1 era.
Impact: This is the first global consensus addressing the rapidly expanding mdWL population, providing practical, multidisciplinary algorithms likely to shape aesthetic assessment and treatment sequencing.
Clinical Implications: Adopt 3D volumetric analysis and PROMs for mdWL assessment; prioritize skin and fat pad changes; plan treatment sequencing to avoid an appearance of weight regain while maintaining natural, healthy outcomes.
Key Findings
- mdWL best defined by the percentage of BMI lost within ≤6 months.
- 3D volumetric analysis is recommended for quantitative assessment; photo-numeric scales and PROMs for qualitative assessment.
- mdWL primarily affects skin and both superficial and deep facial fat pads.
- Consensus details selection and timing of non-surgical treatments across the mdWL journey and addresses patient/physician concerns.
Methodological Strengths
- International, multidisciplinary panel with three-round Delphi methodology.
- Triangulated preparatory work (patient interviews, market research, systematic literature review).
Limitations
- Consensus-based guidance lacks randomized comparative evidence.
- Panel size and voting thresholds not specified in the abstract; external validity may vary by practice setting.
Future Directions: Prospective validation of proposed assessment tools and treatment sequencing, and head-to-head studies of aesthetic interventions stratified by mdWL trajectory and tissue changes.
3. Ruxolitinib cream monotherapy for facial and/or neck atopic dermatitis: results from a decentralized, randomized phase 2 clinical trial.
In a decentralized, double-blind phase 2 trial (n=77), twice-daily 1.5% ruxolitinib cream achieved higher head/neck EASI-75 responses at Week 4 than vehicle (37.0% vs 17.4%) using blinded photographic assessments; treatment was well tolerated. After Week 4, all patients used as-needed ruxolitinib through Week 8.
Impact: Provides controlled evidence specific to the cosmetically sensitive face/neck areas using decentralized, blinded photographic assessments, supporting topical JAK inhibition in regions where tolerability and safety drive prescribing.
Clinical Implications: Ruxolitinib cream is a reasonable option for facial/neck AD where steroid-sparing and tolerability are priorities; decentralized photo-based monitoring could facilitate access and adherence.
Key Findings
- Randomized 2:1, double-blind, decentralized phase 2 trial with 77 patients (44.2% Black), baseline head/neck EASI 1.2.
- Week-4 head/neck EASI-75 responses favored ruxolitinib cream over vehicle (37.0% vs 17.4%) using blinded central photographic assessment.
- Ruxolitinib cream was well tolerated; all patients transitioned to as-needed use through Week 8.
Methodological Strengths
- Double-blind randomized design with central blinded photographic assessment.
- Decentralized trial conduct increases generalizability and patient access.
Limitations
- Short primary treatment window (4 weeks) and small sample size limit power and durability assessment.
- Low baseline head/neck EASI may constrain generalizability to more severe disease.
Future Directions: Larger, longer trials comparing ruxolitinib cream to active comparators on face/neck, with safety endpoints relevant to sensitive skin and skin of color, and real-world decentralized monitoring.
