Purpose: To compare subjective quality of vision between two wavefront-guided lasers in the treatment of myopia up to 1 year postoperatively.
Methods: In this prospective randomized study, 100 eyes of 50 patients were treated with wavefront-guided LASIK. One eye was treated with the WaveLight Allegretto Wave Eye-Q 400-Hz excimer laser (Alcon Laboratories, Inc., Hünenberg, Switzerland) and the other was treated with the VISX Star S4 IR CustomVue excimer laser (Abbott Medical Optics, Santa Ana, CA). Patients completed a questionnaire assessing quality of vision and visual symptoms preoperatively and at postoperative months 1, 3, 6, and 12.
Results: The Allegretto system demonstrated non-statistically significant superiority in several subjective parameters as early as 1 month after surgery. At 12 months, there was better clarity during the day (P = .001) in the Allegretto group. Subgroup analyses were performed on eyes with preoperative higher order aberrations of 0.3 µm or less and in patients with preoperative higher order aberrations greater than 0.3 µm. In subgroup analysis, there were no differences between the two systems in eyes with low higher order aberrations or high higher order aberrations. Patients did not express any preference for one system over the other when surveyed at 1 year postoperatively.
Conclusions: One year after surgery, there were no differences in self-reported quality of vision outcomes with the exception of better clarity of vision during the day in the eyes treated with the Allegretto system. Patients did not express any preference for one treatment modality over the other.

Optic nerve gliomas (ONG) are benign central nervous system tumours and the most common tumours of the optic nerve in children, often occurring before age 20. These tumours are slow-growing and can be treated with surgery and/or radiation therapy. Surgical resection is, however, associated with significant morbidity and loss of vision in the affected eye.

To analyze patients' quality of life (QOL) after laser vision correction (LVC) from a worldwide literature review. Studies of prospective or cross-sectional design which evaluated QOL in patients after LVC and compared that to preoperative values or a matched group of emmetropes were included. The Web of Science, PubMed, Scopus, and ProQuest were searched for relevant articles published until February 2024.

The integration of artificial intelligence (AI) into new approach methods (NAMs) for toxicology rep-resents a paradigm shift in chemical safety assessment. Harnessing AI appropriately has enormous potential to streamline validation efforts. This review explores the challenges, opportunities, and future directions for validating AI-based NAMs, highlighting their transformative potential while acknowledging the complexities involved in their implementation and acceptance.

Visual impairment is an important factor in the decline of patients' quality of life. The purpose of this study is to investigate the impact and feasibility of carrying out low vision rehabilitation nursing on the quality of life and nursing burden of low vision patients.
