Comprehensive Assessment Of The Condition Of The Ocular Surface In Patients Before And After Refractive Surgery

To conduct a comprehensive assessment of the condition of the ocular surface, including data from subjective and objective methods of studying dry eye syndrome, in patients before and after refractive surgery. 

In this study, a comprehensive assessment of the condition of the ocular surface was carried out in the first group - 30 patients (30 eyes) who are scheduled for surgery using FemtoLasik technology with initially no subjective signs of dry eye syndrome and in the second group - 30 patients (30 eyes) who are scheduled for surgery using refractive lenticular extraction technology (SMILE) with initially no subjective signs dry eye syndrome. 

The diagnosis of dry eye syndrome was established based on the results of a comprehensive examination of the ocular surface, which included, along with traditional ophthalmological methods - biomicroscopy of the anterior segment, a test screen, staining of the ocular surface with fluorescein solution, Norn samples, and special ophthalmological diagnostic methods using modern diagnostic modules for assessing the condition of the ocular surface of the Mediworks slit lamp (China) and Sirius corneotopograph Schwind (Germany). The subjective severity of dry eye syndrome was determined using a test questionnaire to identify clinical signs of xerosis of the ocular surface - OSDI. 

There is a discrepancy between the data of subjective and objective methods of examination of the ocular surface in patients with refractive profile, which requires optimization of screening for dry eye syndrome before refractive surgery. 

A comprehensive diagnostic approach to assessing the condition of the ocular surface, based on subjective and objective data, forms a holistic view of the homeostasis of the ocular surface in refractive profile patients, which will subsequently determine the choice of the optimal laser vision correction technology, the tactics of patient administration and the features of the course of the postoperative period.
