Theranostic‐Guided UV‐A Light Corneal Wavefront Photo‐Reshaping for Presbyopia Correction: A Preclinical Study

Journal of Biophotonics, Volume 18, Issue 2, February 2025.
This study investigated a theranostic‐guided UV‐A light corneal wavefront photo‐reshaping technique in human eyes using an integrated system for spatially patterned delivery of riboflavin. Results showed consistent corneal steepening, reduced spherical aberration, and smooth wavefront shaping, with unchanged optical quality, suggesting potential ...

Sustainability in Cataract and Refractive Surgery: Current Challenges and Future Perspectives

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
Cataract and refractive surgery are integral to improving vision health and quality of life; however, their growing environmental impact poses significant concerns. These procedures contribute notably to medical waste, excessive energy consumption, and pharmaceutical overuse, amplifying the carbon footprint of health care.

The Impact of Horizontal Marking on the VisuMax Surgical Bed Headrest on the Outcomes of Myopic Astigmatism Correction With Small Incision Lenticule Extraction

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
Aims: To investigate the impact of horizontal markings on the VisuMax surgical bed headrest on the accuracy of astigmatism correction in small incision lenticule extraction (SMILE). Methods: This retrospective study categorized preoperative astigmatism severity into low‐astigmatism (−0.25 to −1.75 D) and moderate‐to‐high astigmatism (−2.00 to −4.50 D).

Peri-operative intrastromal corneal segmentation after creation of corneal cuts based on laser induced optical breakdown: A perspective study

Journal of the European Optical Society-Rapid Publications
Refractive correction techniques, such as Lenticule Extraction and LASIK, are pivotal in corneal surgery. Precise morphological characterization is essential for identifying post-operative complications, which can be compromised by image noise and low ...

Comparison of dry-eye parameters after three kinds of all laser corneal refractive surgery [PDF]

, 2015
准分子激光角膜屈光手术是目前应用最广泛的矫正近视的方法之一，经过30年的发展，检查设备和手术仪器越来越先进，但是术中及术后角膜瓣的并发症依然无法完全避免。2000年后飞秒激光应用于角膜屈光手术，开创了全激光角膜屈光手术的时代，飞秒激光辅助的准分子激光原位角膜磨镶术（FS-LASIK）使得角膜瓣的制作更加安全，而飞秒激光小切口基质透镜取出术（SMILE）进一步实现了无角膜瓣的角膜屈光手术，经上皮准分子激光屈光性角膜切削术（TransPRK）应用单一的准分子激光完成角膜上皮和基质层的切削 ...

Quality of Life After Laser Vision Correction: A Systematic Review and Meta‐Analysis

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
Purpose: To analyze patients’ quality of life (QOL) after laser vision correction (LVC) from a worldwide literature review. Methods: 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.
