Abstract Details

Purpose:

Analysis of corneal topography data to identify and evaluate signs of Dry Eye Disease and comparison of corneal surface data before and after dry eye treatment in surgical refractive patients.

Setting:

Kyiv Eye Microsurgery Center

Methods:

The keratotopographic data of refractive surgical patients (3 clinical cases) before and after treatment of dry eye disease were presented and analyzed. Case 1: Changes in topography data in candidacy for Clear Lens Extraction with Multifocal Toric IOL. Case 2: Keratotopographic data dynamic reflected the preoperative ocular surface optimization in a cataract surgery patient and made it possible to accurately calculate the multifocal IOL. Case 3: Treatment after Laser Refractive Surgery improved corneal regularity, vision quality and patient satisfaction

Results:

Corneal topography can detect subtle irregularities to the ocular surface. Missing data on topography, poor data repeatability, red hot cone-like spots due to steepenin are common result of dry eye.Topographic indices allow more quantitative analysis of topographic data. Changes in index values characterize the change in the regularity of the corneal surface. Keratotopography allows to evaluate the quality of treatment for dry eye disease. With the stabilization of the tear film, the surface of the cornea becomes more regular, dry spots disappear, topographic indices change, and measurements become repeatable.

Conclusions:

Dry eye disease has an adverse effect on vision quality, refractive error determination, corneal imaging and refractive surgery results. Keratotopography is a powerful non-invasive tool for assessment corneal shape and identify patients with irregular cornea related to dry eye disease that requires treatment. Topography is important to determine dry eye treatment efficacy. Furthermore, in cases of refractive surgery, keratotopography helps with patient selection, proper preoperative preparation and postoperative treatment, which significantly improves the surgery outcomes.
