The association between upper tarsal conjunctiva appearance and corneal biomechanical weakening in refractive surgery candidates.

ABSTRACT: Current evidence suggests allergic conjunctivitis and contact lens use may affect corneal biomechanics, but the relationship between conjunctival changes and biomechanical abnormalities remains unclear. This study aimed to determine whether upper tarsal conjunctival roughness and redness are associated with corneal biomechanical weakening in refractive surgery candidates without ectatic corneal disease. Conducted at Chiang Mai University LASIK Center between July 2023 and January 2024, conjunctival roughness and redness were graded using the Institute for Eye Research (IER) scales, while corneal biomechanics were assessed through Corvis parameters. The study included 434 eyes from 217 participants (70.5% female), with a mean age of 33.4 years (SD 8.3). Ocular allergy was reported by 23.0%
