U.S., March 19 -- ClinicalTrials.gov registry received information related to the study (NCT07481227) titled 'FS-LASIK Versus TransPRK for Mixed Astigmatism' on March 15.
Brief Summary: Mixed astigmatism is a type of refractive error in which the two principal steep and flat meridians focus the light in front and behind the retina, respectively.1 Laser vision correction (LVC) for mixed astigmatism is challenging as it involves a bitoric ablative pattern to flatten the steepest meridian and steepen the flattest one. The aim of the current study was to compare the visual and refractive outcomes of FS-LASIK versus single-step TransPRK for treatment of patients with mixed astigmatism.
