Factors Influencing Refractive Surgery Rejection in Israeli Patients

Background: One of the major causes of reversible visual impairment is a refractive error, which can be corrected through refractive surgery. Data regarding the outcomes and complications of these procedures exist; however, there is a notable gap in understanding the factors leading to patient rejection, particulariy in diverse populations Like Israel. Objectives: To detect clinical risk factors of patients who intend to undergo LASIK procedure and to improve the conversion rates of LASIK procedure in this population. Methods: The study included a retrospective analysis of patients who were rejected from having refractive surgery in two Enaim Refractive Surgery Centers: Jerusalem and Tel Aviv. Comparisons between centers were conducted using the t-test for continuous variables and Fisher's exact test for categorical data. Results: Our study included 337 patients who were rejected from having refractive surgery, including 152 (45.1%) who were rejected permanently and 185 (54.9%) rejected temporarily. The most common reasons for permanent rejection were corneal irregularity (n=81, 53.3%), keratoconus (n=27, 17.8%), thin Corneas (n=13, 8.6%), and amblyopia (n=10, 6.6%). The most common temporary reasons were unstable refraction (n=96, 51.9%), prolonged use of contact lenses (n=54,29.2%), and corneal irregularity (n=16, 8.6%). Conclusions: The leading permanent cause of rejection for refractive surgery was a corneal irregularity, whereas the primary temporary cause was unstable refraction. In a time of rapid technological advancements and growing demand for freedom from glasses, there is an increasing need for more informed and patient-focused refractive correction approaches.
