Evaluating the effectiveness of chatbots and traditional resources in patient education on dry eye disease Gizem Gürbostan Soysal, Murat Mercanlı, Zeynep Özer Özcan, İbrahim Edhem Yılmaz, Mustafa Berhuni Clinical and Experimental Optometry, 2026 CLINICAL RELEVANCE Artificial intelligence chatbots demonstrate potential as valuable educational resources for patients with dry eye disease, offering complementary information to established medical platforms. BACKGROUND The increasing prevalence of dry eye disease necessitates reliable and comprehensible patient information resources. This study evaluates and compares the quality of information provided by contemporary AI chatbots with established ophthalmological sources. METHODS Three leading AI chatbots (ChatGPT-3.5, Gemini, and Llama) and the American Academy of Ophthalmology (AAO) website were systematically evaluated using 20 common patient questions about dry eye disease. Responses were assessed for accuracy using the Structure of Observed Learning Outcome (SOLO) taxonomy, understandability and actionability using the Patient Education Materials Assessment Tool (PEMAT), and linguistic accessibility using Flesch-Kincaid readability metrics. RESULTS Gemini demonstrated superior understandability with a mean PEMAT-U score of 73.4 ± 11.4, significantly higher than ChatGPT (65.4 ± 10.6), Llama (63.4 ± 10.3), and AAO (52.5 ± 19.3) (p < 0.001). No significant differences were observed in actionability scores (p = 0.120). The AAO website exhibited the highest reading ease score (50.4 ± 17.9, p = 0.015). For accuracy assessment, ChatGPT achieved the highest mean SOLO score (3.4 ± 0.7), followed closely by Gemini (3.3 ± 0.8), with no significant performance differences detected among chatbots (p = 0.574). No instances of incorrect or potentially harmful information were identified across any evaluated source. CONCLUSION While AI chatbots demonstrate promising capabilities for patient education in dry eye disease, particularly in providing comprehensive and understandable information, their higher linguistic complexity presents a potential accessibility barrier. Future development should focus on enhancing readability while maintaining comprehensive content, positioning chatbots as valuable complements to - rather than replacements for - professional medical consultation.
Long term results for transepithelial and standard photorefractive keratectomy in the treatment of moderate to low myopia and astigmatism Nesime Setge Tiskaoglu, Mustafa Berhuni, Cem Ozturkmen Turkish Journal of Clinical and Experimental Ophthalmology, 2025 Purpose: To evaluate the results of photorefractive keratectomy (PRK) and transepithelial PRK (t-PRK) in moderate and low-grade myopia and astigmatism. Materials and Methods:The records of 144 eyes of 72 t-PRK and 132 eyes of 66 PRK patients were retrospectively analysed.Pre and postoperative 36-month best corrected visual acuity (BCVA) and refractive errors were recorded.Surgical values as well as postoperative epithelial healing and haze staging were also recorded. Results:The average age of t-PRK patients was 28.296.8years, and the average age in the PRK patient group was 28.155.0years.The time to epithelial closure was significantly longer in the PRK group compared to the t-PRK group.T-PRK and PRK group showed significant improvement in postoperative BCVA, spherical and cylindrical refraction. Conclusion:T-PRK and PRK procedure was found to be both effective and safe in our population group.
Lack of Response to Intravitreal Ranibizumab Treatment in Adult Onset Foveomacular Vitelliform Dystrophy Complicated with Choroidal Neovascularization. A Case Report Mustafa Berhuni, Nesime Setge Tıskaoğlu, Cem Ozturkmen Ceska A Slovenska Oftalmologie, 2025 Adult-onset foveomacular vitelliform dystrophy (AOFVD) is a rare disease characterized by accumulation of yellowish deposits in the macula. Rarely, it may be complicated by choroidal neovascularization (CNV). Cases with CNV may be confused with occult CNV in age-related macular degeneration. In our case, we will present the visual and anatomical results of a patient with AOVF-related CNV, in which we administered 3 doses of intravitreal ranibizumab (IVR). A 59-year-old female patient, who attended our clinic with the complaint of decreased vision in both eyes, was diagnosed with AOVF-related CNV in both eyes and was treated with 3 doses of IVR for 3 months. Despite the improvement in visual and anatomical functions 1 month after the first dose, vision decreased, and anatomical functions regressed to the pre-injection state in continued injections. IVR therapy is not an appropriate treatment option in the treatment of AOVF-associated CNV.
Choroidal Vascularity Index and Subfoveal Choroidal Thickness in Rheumatoid Arthritis Assessed with Enhanced-Depth Imaging Optical Coherence Tomography Mustafa Berhuni, Fatih Albayrak, Mehmet Göl Ocular Immunology and Inflammation, 2025 PURPOSE To evaluate the effects of rheumatoid arthritis (RA) on choroidal vascularity index (CVI) and subfoveal choroidal thickness (SFCT). METHODS The study included 56 eyes of 56 rheumatoid arthritis patients and 65 eyes of 65 age- and sex-matched healthy normal participants. CVIs of all participants were measured by transferring enhanced depth imaging optical coherence tomography (EDI-OCT) images to the image J program that is software used for image binarization and compared between the 2 groups. SFCT, central macular thickness (CMT) and optic disc parameters of all participants were measured with spectral domain OCT and compared. RESULTS The mean CVI values of the RA and control groups were 65.9 ± 1.52 and 68.56 ± 1.62, respectively, and were significantly lower in the RA group (p = 0.001). Mean SFCT values of the RA and control groups were 290.11 ± 15.18 and 332.88 ± 11.04, respectively, and SFCT was significantly lower in the RA group (p = 0.001). RA patients have thin SFCT and low CVI. There was no significant difference between the two groups in terms of CMT and optic disc parameters. CONCLUSION RA patients have lower CVI and thinner SFCT than healthy participants.
Focusing on the Future: Patient-Centered Insights into Trifocal Intraocular Lens Adoption Ibrahim Edhem Yilmaz, Mustafa Berhuni, Cem Öztürkmen, Hakim Ali Reyhan Ceska A Slovenska Oftalmologie Casopis Ceske Oftalmologicke Spolecnosti A Slovenske Oftalmologicke Spolecnosti, 2025 AIMS To analyze determinants affecting the selection of trifocal intraocular lenses (IOLs) and to evaluate patient satisfaction and adaptation patterns post-implantation in a Turkish cohort. MATERIAL AND METHODS A cross-sectional study was conducted using a 17-item questionnaire administered to 96 patients who underwent phacoemulsification with PanOptix trifocal IOL implantation. Demographics, IOL selection factors, surgeon trust, visual adaptation, and satisfaction metrics were analyzed across various patient subgroups. RESULTS The cohort (mean age 60.62 ±11.94 years; 58.3% male) demonstrated 96.9% overall satisfaction post-implantation. Significant findings included higher satisfaction rates among patients under 65 years (98.3% vs 94.7%, p = 0.042), among tertiary-educated patients (98% vs 75%, p = 0.03), and 82.3% complete spectacle independence. Visual phenomena were reported at contemporary rates (glare: 18.8%, halos: 22.9%). Ninety-one percent of patients achieved visual adaptation within three months. Preoperative counseling participation (86.7% vs 71.4%, p = 0.035) and consistent follow-up attendance (88.9% vs 73.3%, p = 0.028) emerged as significant predictors of satisfaction. CONCLUSION Patient satisfaction with trifocal IOLs correlates significantly with age, educational background, and engagement in the treatment process. While overall satisfaction rates are high, outcomes appear influenced by demographic factors and healthcare engagement patterns. These findings emphasize the importance of comprehensive preoperative assessment, patient education, and tailored follow-up protocols in optimizing trifocal IOL outcomes across diverse population segments.
