What this Trial Is About
Researchers are analyzing the outcomes of cataract and refractive surgeries by reviewing patient data retrospectively. The goal is to continuously assess visual and refractive results and to compare different intraocular lenses (IOLs) and refractive procedures. This observational study focuses on adult patients who have undergone these eye procedures. The study includes patients who have received refractive or cataract surgery with implantation of an intraocular lens. There are no treatment interventions or new procedures in this study; rather, it collects and analyzes existing clinical data from patients of the clinic who have already undergone these surgeries. Participants' visual outcomes will be evaluated 3 to 6 months after their surgery. Researchers will assess various measures including uncorrected and distance-corrected visual acuity at different distances, subjective refraction, accuracy of achieved refraction compared to the target, and quality of vision through questionnaires and contrast sensitivity tests. The study also monitors surgical and post-operative complications to better understand the results of these procedures.
