Comorbidities in Corneal Refractive Surgery Candidates: A Cross-Sectional Study

Background: Individuals with refractive errors sometimes have other associated ocular and systemic abnormalities. Objectives: To explore comorbidities in Corneal Refractive Surgery (CRS) candidates to examine any contraindications for CRS. Methods: This was a cross-sectional study. Medical records of individuals who underwent surgery screening at Chiang Mai University LASIK Center, Mai, Thailand, were reviewed. All clinical data the initial visit evaluated. Eyes history CRS phototherapeutic keratectomy excluded. Results: A total 1,167 cases (2,334 eyes) recruited, out which 643 females (55.09%). Myopia most common type error (2,120 eyes, 90.83%), 868 (40.94%) eyes had high myopia. Approximately 45% (n=526) worn contact lenses. The five (eyes, proportion) included keratoconus suspect (297, 12.72%), cataract (246, 10.53%), dry eye/probable eye (208, 8.91%), glaucoma (184, 7.88%), amblyopia (149, 6.38%). conditions that affected choices or outcomes hypertrophic scar/keloid (169 cases, 14.48%) followed by allergy/asthma (127 10.88%). 1,028 (44.04%) excluded from CRS, mainly due abnormal corneal topography (470/1,028 45.72%). Conclusion: Most myopic lens wearers. Serious sequelae myopia use not uncommon. Additionally, diseases regularly options. contraindication topography. Our study, thus, emphasizes need thorough screenings candidates.
