Background: Pseudoexfoliation syndrome (PEX) is a common age-related ocular condition characterized by the accumulation of a fibrillar, pseudoexfoliative material on the anterior segment of the eye. This study aims to investigate the histopathological characteristics of pseudoexfoliative material within different ocular structures, including the eyelid, conjunctiva, and anterior lens capsule. Methods: A total of 32 anterior lens capsules, 3 eyelid fragments, and 12 conjunctival specimens were obtained from patients clinically diagnosed with PEX during ocular surgeries at the Onioptic Hospital of Ophthalmology. The tissue specimens were subsequently processed using the classical histological technique of paraffin embedding. This process enabled the production of serial sections with a thickness of 4 microns, facilitating the microscopic examination of fine details. The sections were stained with the hematoxylin-eosin (HE) method for the observation of microscopic structures. Results: This study’s findings reveal that PEX material, characterized by its fibrillar and amorphous components, is consistently present across multiple ocular structures, including the anterior lens capsule, eyelid, and conjunctiva. When stained with H&E, the PEX material typically appears as amorphous, eosinophilic deposits. Under higher magnification, these deposits exhibit a fibrillar structure, often appearing as irregular, granular, or filamentous aggregates. Conclusions: The deposit of fibrillar material in the eyelid and conjunctiva, though less commonly emphasized compared to other structures, is a significant finding that sheds light on the systemic nature of the syndrome. The consistent identification of fibrillar eosinophilic deposits across these structures highlights the systemic distribution of PEX material, reinforcing the notion that PEX syndrome is not confined to the anterior segment of the eye.
Background: This study aims to evaluate the visual performance, both quantitative and qualitative, of the novel non-diffractive extended monofocal intraocular lens (Evolux, Sifi) following cataract surgery. This serves as a preliminary study to assess its feasibility and improve the research methodology. Methods: We conducted a single-arm, non-randomized, retrospective study at Onioptic Hospital, Craiova, Romania, involving patients who underwent cataract surgery from November 2022 to August 2023. The following visual parameters were evaluated 3 months postoperatively: monocular uncorrected (UDVA) and corrected (CDVA) distance visual acuity at 4 m; uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuity at 60 cm; uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity at 40cm; postoperative refraction expressed as spheric equivalent (SE) and Quality of Vision (QoV) questionnaire scores. The contrast sensitivity and defocus curve were evaluated 1 month postoperation in 22 patients who underwent surgery in both eyes. SPSS Statistics 26.0 was used for statistical analysis, employing percentages, standard deviations (SDs), and a 95% confidence interval (95% CI). Results: Among the 103 eyes from 81 patients (mean age of 68.7 ± 1.845), 64% achieved an UDVA of logMAR 0.1 or better, and 91.26% achieved a CDVA of logMAR 0.1 or better at 3 months. Additionally, 83.24% of the eyes exhibited a UIVA of logMAR 0.3 or better, and 60.19% attained an UNVA of logMAR 0.3 or better. The SE was within ±0.50 D in 77.76% of the eyes. The QoV mean scores were as follows: frequency = 30.20 ± 16; severity = 17.19 ± 12.45; bothersome = 15.45 ± 12.94. Conclusions: The Evolux IOL demonstrated very good biometric predictability and excellent distance visual performance and very good intermediate vision, with no photopic side effects or glare in our sample population. This study provides a strong foundation for a larger comparative study with an extended depth-of-focus (EDOF) IOL, incorporating contrast sensitivity and defocus curve assessments to enhance the research quality.
